          KEETON, District Judge.   Appealing from a judgment for
                                          

the defendant  on a  jury verdict, plaintiff-appellant  argues an

interesting undecided  issue of  New Hampshire law  regarding the

scope  of strict  liability on  the ground  of product  defect in

relation  to warning  and instructions  for use.   May  a product

marketer be held strictly liable on the basis of failure to warn,

for  harm  to  a  building  into which  its  product  (containing

asbestos fibers) was  installed, even though the jury  has found,

in answering  special questions,  that plaintiff failed  to prove

any departure from ordinary prudence with respect to warning  and

instructions for use?

          We  conclude  that  the  jury  findings,  together with

settled  rules  of  federal  procedural  law  and  New  Hampshire

substantive law, preclude our reaching this interesting question.

For  the reasons  explained,  we  affirm  the  judgment  for  the

defendant on the verdict of the jury.

                                I.
                                          I.

          Plaintiff-appellant  alleged that  defendant's product,

Monokote  3,  a fireproofing  material,  purchased in  1971  by a

subcontractor  in  compliance with  specifications,  and used  in

constructing  a building occupied and used  at all relevant times

by plaintiff (an  entity designated in  the general contract  for

construction of the building as "owner") was defective because of

a  percentage of  asbestos  particles in  the  product.   In  the

various  counts of  the  complaint, plaintiff  alleged claims  of

negligence (in manufacture, sale, and warning), strict  liability

                               -2-


for product defect, and breach of implied warranty.

          The case was submitted to  a jury on special questions,

Fed. R. Civ. P. 49(a).  The jury returned the following answers:

                       SPECIAL VERDICT FORM
                                                     
               1.    On  the statute  of  limitations
            defense, do you find for the Plaintiff or
            the Defendant?

                x  Plaintiff               Defendant
                                                     

               If you find for the Defendant  on this
            issue, stop and return a verdict in favor
            of the Defendant.

               If  you find for the Plaintiff on this
            issue, answer questions 2, 3, 4, 5 and/or
            6.

               2.  On  Plaintiff's negligence  claim,
            do  you find  for  the Plaintiff  or  the
            Defendant?

                   Plaintiff            x  Defendant
                                                     

               3.  On Plaintiff's  products liability
            claim, do  you find for the  Plaintiff or
            the Defendant?

                   Plaintiff            x  Defendant
                                                     

               4.    On Plaintiff's  implied warranty
            claim,  do you find  for the Plaintiff or
            the Defendant?

                   Plaintiff            x  Defendant
                                                     

               5.  If you  found for the Plaintiff on
            one or more of  its claims (questions  2,
            3,  or  4)  please  write  the amount  of
            damages  you  award  to  Plaintiff  using
            words  and  figures   (as  in  writing  a
            check).

               Damages awarded:       ----none----   
                                                               

                          ($          )

               6.  If you  found for the Defendant on

                               -3-


            each of Plaintiff's claims  (questions 2,
            3, and 4), then return a verdict in favor
            of Defendant.

DATE:  11/3/93                   /s/             
                                                           
                           Foreperson

          The court's  charge to  the jury  included instructions

advising  the  jury they  should  answer that  the  plaintiff had

proved  negligence  if  they  found by  a  preponderance  of  the

evidence that  defendant failed to exercise  ordinary prudence in

manufacture, or  in sale,  or in  relation to warning  (including

instructions  for use).   Thus, unless  plaintiff-appellant shows

some trial error that undermines this finding (and we conclude in

Part III, infra, that  plaintiff-appellant has failed to  do so),
                         

we  must accept  as  an established  fact  that, in  relation  to

warning and instructions for use of the product, plaintiff failed

to prove any departure from ordinary prudence.

          The  court's charge  to  the jury  on strict  liability
                                                                           

failed to  include any reference  to warning or  instructions for

use.     We  assume,  as  did  the  trial  court  in  considering

plaintiff's  motion  for new  trial, that  this  was error.   See
                                                                           

Chellman v. Saab-Scania AB, 637 A.2d 148 (N.H.  1993).  The trial
                                    

court concluded, however, that the error was harmless.  So do we,

though on  somewhat different  reasoning from that  of the  trial

court because, unlike  the trial  court, we do  not undertake  to

predict  exactly  how the  Supreme  Court of  New  Hampshire will

resolve  a novel  issue of  substantive law  on which  plaintiff-

appellant relies.

                               II.
                                         II.

                               -4-


          It  is  settled  law   in  New  Hampshire  that  strict

liability  for  product  defect  includes  manufacturing  defect,

design defect, and warning  defect.  See Chellman, 637  A.2d 148;
                                                           

see  also Brochu v. Ortho Pharmaceutical Corp., 642 F.2d 652, 661
                                                        

(1st Cir. 1981).

          New Hampshire cases  have not yet  determined, however,

whether, as appellant asserts,  a breach of the  strict liability

duty to warn can be proved on some basis short of proving failure

to  exercise  ordinary  prudence   in  relation  to  warning  and

instructions for use.  Stated another way, the undecided question

is  whether the duty of warning under the strict liability theory

requires something more  of the  marketer than does  the duty  of

warning under negligence law and, if so, what.

          Whether  the  duty  is  more onerous  is  an  unsettled

question  of   New  Hampshire  substantive  law.     Contrary  to

appellant's assertion, this question of New Hampshire law was not

decided in Chellman, 687 A.2d  148.  Instead, that was a  case in
                             

which the  plaintiff did not ask the court to submit a negligence

claim to  the jury.  See  id. at 151.  In  that context, omission
                                       

from the trial court's  charge of even an instruction  on prudent

care  with  respect  to  warning  was  reversible  error  because

plaintiff was completely  deprived of the opportunity to have the

jury consider the duty-to-warn claim.  In this case, in contrast,

the jury did consider  a duty-to-warn claim.   They did so  under

the  negligence question.   And  we must  conclude that  the jury

rejected that claim because they were instructed that they should

                               -5-


find for  plaintiff in answering the negligence  question if they

found for the plaintiff  on other grounds or  if they found  that
                                                      

defendant failed to use ordinary prudence in relation  to warning

or instructions for use and that this failure was a  cause of any

harm sustained by plaintiff.

          In three separate avenues of attack, appellant seeks to

avoid  the preclusive  effect of  the jury  finding of  no causal

negligence.   The  first avenue  is a  two-fold challenge  to the

finding itself, which  we discuss in  Part III.   We examine  the

other avenues separately in Parts IV and V.

                               III.
                                         III.

          Appellant  has  challenged  the  jury's  finding  of no

causal negligence  on two  grounds.   Appellant asserts that  the

trial court's  duty-to-warn instruction  on the negligence  count

was erroneous.  Appellant also asserts that the trial court erred

in  failing to instruct the  jury on the  New Hampshire statutory

asbestos  exposure standard.   We conclude that  neither of these

attacks has merit.

A.        The Duty-To-Warn Instruction Given
          A.        The Duty-To-Warn Instruction Given

          Appellant challenges the duty-to-warn instruction given

by  the  trial court  on  the  negligence claim.    The jury  was

instructed  that the defendant had a duty  to warn if it "knew or

should  have known that the fireproofing it sold to the plaintiff

was  dangerous  to  people or  that  it  would  damage property."

Appellant argues  that this  instruction is erroneous  because it

requires the plaintiff to prove that the product "was dangerous."

                               -6-


Relying on  language in  Chellman,  the appellant  argues that  a
                                           

defendant has a duty to warn if a product "may be dangerous."

          This argument is based more on form than substance.  It

is difficult to  imagine what different meaning would be conveyed

by  an instruction, instead of that given, that the defendant had

a  duty  to  warn if  it  knew  or  should  have known  that  the

fireproofing it sold to the  plaintiff may be dangerous.   To the
                                                    

extent that  this  phrasing  conveys  the  same  meaning  --  for

example, that  the defendant had a duty  to warn if the defendant

knew or should  have known that the  product causes harm  in some

(but not necessarily  all) instances -- the  instruction given by

the court was not in error.

          To  the  extent  that  appellant  is  urging  that  its

proposed  language  conveys  a  different  meaning  --  that  the

defendant has a  duty to warn if it should  have known that there

was a  mere possibility that the  product was in the  category of

dangerous products (i.e., one that causes harm in some instances)

-- the  argument for application of  a legal test  framed in this

particular way has no basis in New Hampshire law.

          Under New  Hampshire law, a manufacturer  need not warn

of all potential dangers associated with a product.  See Thibault
                                                                           

v. Sears, Roebuck  & Co., 395  A.2d 843 (N.H.  1978)(manufacturer
                                  

need  not  warn of  known, but  very  unlikely, risk  of danger).

Similarly, one may  infer from  this precedent that  there is  no

duty to warn on the basis of speculation that a  product might be

dangerous.  Thus, the meaning conveyed by the court's instruction

                               -7-


is closer to the  formulations found in New Hampshire  cases than

is appellant's  proposed alteration,  which itself is  subject to

different interpretations, some  of which  are inconsistent  with

the  formulations in the New  Hampshire cases.  Thus, appellant's

challenge on this ground fails.

B.        The New Hampshire Asbestos Exposure Standard
          B.        The New Hampshire Asbestos Exposure Standard

          Appellant  challenges  the  trial  court's  failure  to

instruct  the  jury on  the  New  Hampshire  standard for  indoor

nonoccupational asbestos exposure.  See N.H. Rev. Stat. Ann. 141-
                                                 

E:6.     This   numerical  standard   (.01  f/cc)   triggers  the

applicability of  certain  New Hampshire  regulations  concerning

asbestos  abatement procedures used as a  part of construction or

maintenance.

          The court instructed the jury  on federal OSHA and  EPA

regulations,   as  well   as   the   New  Hampshire   regulations

establishing procedures to be  followed during asbestos abatement

projects.   The court told  the jury that  the various  state and

federal statutes were relevant  to the issue of damages  only and

not  to the  defendant's  liability.   Since  the jury  found  no

liability and therefore did  not reach the issue of  damages, the

court's alleged error  in failing to instruct the jury on the New

Hampshire   asbestos   exposure  standard   is,   in  retrospect,

irrelevant and therefore harmless, unless appellant can establish

relevance to liability issues.

          Appellant's challenge on  appeal contains the  implicit

assertion that  the New  Hampshire asbestos exposure  standard is

                               -8-


relevant to  the defendant's liability.   The appellant, although

objecting to the court's  failure to instruct the jury on the New

Hampshire statute, did  not object  to that part  of the  court's

instruction telling the jury that these statutes were relevant to

the issue of damages only and not to the issue of liability.  The

appellant  having  failed  in  its  objections  and  request  for

instruction to articulate an  argument for relevancy to liability

or any legal  basis for  relevancy, we review  the trial  court's

instruction only  for plain error.  See  Poulin v. Greer, 18 F.3d
                                                                  

979, 982 (1st Cir. 1994).

          We  conclude that it was  not plain error,  if error at

all.   The  New  Hampshire asbestos  exposure  standard does  not

impose  a  rule of  conduct on  sellers  of asbestos  products or

contractors using  asbestos products.  Instead,  it establishes a

threshold of  authorization for the  director of the  Division of

Public  Health Services  to  take certain  regulatory action,  if

warranted.   See N.H. Rev.  Stat. Ann. 141-E:8.   In addition, it
                          

triggers  the  applicability  of  certain  safety regulations  to

asbestos removal  and abatement projects  at relevant  buildings.

See N.H. Rev. Stat. Ann. 141-E:7.
             

          We conclude that no  decision cited to us, and  none of

which we are aware, establishes a basis for plaintiff's assertion

that the New Hampshire asbestos exposure standard  is relevant to

the  defendant's  liability.     Moreover,  given  that  the  New

Hampshire state regulators have  taken no action with  respect to

appellant's building, the  standard at issue bears only  upon the

                               -9-


calculation  of costs  the appellant might  incur in  the future.

For these  reasons, we hold that  even if there was  error in the

trial  court with respect to this  asbestos exposure standard, it

was harmless in this case.

                               -10-


                               IV.
                                         IV.

          In oral  argument and  in its brief,  appellant asserts

that  as a matter  of substantive law  a claimant  is entitled to

have the court instruct  the jury that a claim  of strict product

liability  is to  be decided  by a  jury in  a single  evaluative

finding after  jury consideration of all relevant factors.  Thus,

for  example, the appellant argues that if the jury thought there

was  some  evidence  of  departure from  ordinary  prudence  with

respect to  warning but not enough evidence  for the jury to find

departure  from  ordinary  prudence  by a  preponderance  of  the

evidence,  the jury  could nevertheless  take this  evidence into

account  among all the other factors  they considered in deciding

whether the product was defective.

          Appellant asserted in oral  argument before this  court

that the jury in  a strict product liability case  is allowed to,

and should be  instructed to,  make one overall  weighing of  all

factors bearing upon (1) manufacturing defect, (2) design defect,

and (3) warning defect.   Appellant cites no precedent explicitly

supporting this contention, and we are aware of none.

          Two  independently  significant  points are  implicitly

essential to the validity of the argument.  We consider each.

A.        Consideration of the Cumulative Effect of the Evidence
          A.        Consideration of the Cumulative Effect of the Evidence

          Appellant's argument depends on an  implicit assumption

that  a   claimant  need   not  establish  independently,   by  a

preponderance  of  the evidence,  any one  of the  three separate

theories  of  strict  liability  (manufacturing   defect,  design

                               -11-


defect, and warning defect).

          In the context of this  case, appellant argues that the

evidence of failure to warn, although not sufficient by itself to

support a finding of  strict liability by a preponderance  of the

evidence, may  be combined  by the  jury with  any evidence  of a

design defect and may result in a finding of  strict liability by

a preponderance  of the evidence.  In some cases, this would lead

to  the  anomalous result  that  the  jury  could find  defendant

strictly liable by a preponderance of evidence without finding by

a preponderance of the evidence a manufacturing defect, a  design

defect, or a warning defect.

          For example, the appellant implies that a plaintiff can

prevail if  the  jury  finds  none  of the  three  defects  by  a

preponderance  of the evidence  and yet  finds that  the evidence

shows a .40 probability  of each and, in some  unexplained way, a

.51 probability of defect in its overall weighing of all evidence

received at trial.

          This  argument is flawed.  A .40 probability of each of

three  separate  defects  cannot  add  up  to  a  .51 probability

overall.  Instead, in this assumed circumstance, unless the three

are interdependent (as  they may be), there  is no better  than a

.064  probability (.40 x .40 x .40)  that all three are true, and

neither mathematically nor as  a matter of common sense  do three

.40 probabilities show a .51 probability that one of the three or

some combination of two or all three is true.

          Moreover, as a matter of settled law, judicial opinions

                               -12-


and commentators  alike refer  to proof of  manufacturing defect,

design  defect, and  warning defect  as three  different ways  of

proving  product defect, not just as factors bearing upon one way

of  proving  product  defect.    See  Brochu,  642  F.2d  at  661

and warning defects").

          Appellant  cites  Chellman  as  holding,  or  at  least
                                              

implying, that there is only one strict product  liability theory

in  New Hampshire  law,  and that  only  one question  about  the

adequacy  of  plaintiff's proof  of  strict  liability should  be

submitted to a jury.  A  close reading of the case, however, does

not support the view  that Chellman addressed the  choice between
                                             

(a)  treating manufacturing  defect, design  defect, and  warning

defect  as  separate  theories,   each  involving  a  distinctive

standard for determining liability, and (b) treating the three as

merely factors  in a single multiple-factors  standard for making

an  evaluative  determination  that a  product  is  or  is not  a

defective product.

          In Chellman, the defendant argued that strict liability
                               

for design defect and  strict liability for failure to  warn were

distinct,  and that the plaintiff  had failed to  plead a strict-

liability-for-failure-to-warn claim.   See Chellman, 687 A.2d  at
                                                             

151.   In  deciding that  the plaintiff's  complaint sufficiently

stated  a  strict liability  claim,  on the  basis  of inadequate

warning, to  meet plaintiff's  burden of  pleading, see  id., the
                                                                      

court  did not  need  to or  purport  to decide  whether  proving

defective warning and proving  defective design in respects apart

from  warning were two  separable ways of  proving strict product

liability.    Thus, Chellman  neither  endorses  nor rejects  the
                                      

general proposition that manufacturing defect, design defect, and

warning defect are commonly treated by courts and commentators as

                               -14-


three separate ways of proving product liability.

          The  commonly accepted  understanding that  a plaintiff

must  establish  one or  another of  the  three kinds  of defects

(manufacturing  defect, design  defect, or  warning defect)  by a

preponderance  of the evidence  leaves the jury  entirely free to

weigh a single  item of evidence as relevant to  claims of two or

even all three kinds of defect.  Thus, for example, New Hampshire

case law  supports the  proposition that evidence  concerning the

existence and adequacy  of a warning  is relevant not  only to  a

warning defect  claim, but  also to a  design defect claim.   See
                                                                           

Chellman, 637 A.2d at 150; Reid v.  Spadone Machine Co., 404 A.2d
                                                                 

1094, 1097 (N.H. 1979)("This  condition [the placement of certain

buttons on  a machine], coupled with  inadequate warnings against

two-person  use, could properly be found to have made the machine

'unreasonably dangerous.'").

          The  issue before  us  now, however,  does not  concern

admissibility of evidence.   The jury was free under  the court's

rulings,  absent limiting instructions,  to consider all evidence

received  at trial.  In these circumstances, we conclude that the

jury's finding of no violation  as to the duty-to-warn negligence

claim bars  the strict-liability-duty-to-warn claim.   This is so

because in finding  that there  was no liability  for failure  to

warn on the negligence theory  the jury necessarily found  either

(1) that  plaintiff failed to prove that the defendant's warnings

and instructions violated the prudent care  standard or (2) that,

if the warning was inadequate, plaintiff failed to prove that the

                               -15-


inadequacy of the warning caused the plaintiff's injury.
                                          

          Under either of the two possible interpretations of the

jury's finding, the jury has determined that plaintiff has failed

to  prove by a preponderance  of the evidence  any violation of a

duty  of prudent  care  as to  warning.   This  bars the  strict-

liability-as-to-warning claim  unless the  law  of New  Hampshire

imposes  a more onerous duty than one  of prudent care as part of

the law of strict product liability.

B.        An All-Factors Evaluative Determination
          B.        An All-Factors Evaluative Determination

          Appellant's weighing-of-all-factors  argument, if taken

at face  value and without  qualification, leads implicitly  to a

surrender of judicial responsibility  for instructing the jury to

respect the law's outside  limits on jury discretion.  It is true

that appellant's argument for an unlimited all-factors evaluative

determination by the jury  has a surface plausibility, which  may

appear to be reinforced by support in some states for application

of a standard requiring the jury to "weigh competing factors much

as they  would in  determining the  fault of the  defendant in  a

negligence case."   Back v.  Wickes, 378 N.E.2d  964, 970  (Mass.
                                             

1978).  Thus:

              In   evaluating   the  adequacy   of  a
            product's   design,   the   jury   should
            consider,   among  other   factors,  "the
            gravity  of  the   danger  posed  by  the
            challenged  design,  the likelihood  that
            such danger would  occur, the  mechanical
            feasibility   of   a  safer   alternative
            design, the financial cost of an improved
            design, and the  adverse consequences  to
            the  product  and  to the  consumer  that
            would result from an alternative design."

234, 242 (E.D. Pa. 1977)).

          The  plausibility of appellant's argument is reinforced

by  the  statement  of the  Supreme  Court  of  New Hampshire  in

Thibault that:
                  

              Inquiry  into  the  dangerousness of  a
            product    requires    a    multi-faceted

            many   conflicting  factors   .  .   .  .

            and similar factors are questions of fact

1988) and discussing the "danger-utility" test used  by the Maine

courts).  Perhaps even more supportive of appellant's argument is

another passage from the opinion of the Supreme Judicial Court of

Massachusetts in Back v. Wickes Corp.:
                                               

              In  balancing  all  of   the  pertinent
            factors [in deciding whether there  was a
            design  defect] the jury makes a judgment
            as  to the  social  acceptability of  the
            design, and  this  is the  same  judgment
            originally  made by  the designer  of the
            product.

378 N.E.2d at 970.

          Even if  one  takes these  passages to  mean that  some

policy weighing is left  to the jury, however, it does not follow

that   the  legal  system   approves  an   unlimited  all-factors

evaluative  determination by  the jury.    Even when  approving a

                               -17-


multiple-factors-weighing-test  for  jury   use  in  finding   an

"ultimate fact,"  such as product  defect, the legal  system does

not authorize the jury  to give whatever weight the  jury chooses

to  arguments of public policy  for and against strict liability.

To do so would leave to  the jury an authority and responsibility

that is  unguided by  any public  policy  determinations made  in

statutes and precedents.

          Ordinarily  issues of  public policy  are in  the first

instance appropriate for a legislature's determination by statute

and, if not determined by statute,  may be determined by a  state

court of last resort in its decisions setting precedents.

          We do not understand appellant's counsel as  explicitly

arguing  for a broad and sweeping jury discretion that extends to

public   policy  issues   ordinarily  decided   by   statutes  or

precedents.   We  consider  the argument  in  this extreme  form,

however, because of the procedural posture of this case.

          Appellant seeks a new  trial despite a supportable jury

finding that defendant did not fail to exercise ordinary prudence

with  respect   to  warning   and  instructions  for   use.  This

contention,  however,  is  procedurally  barred  unless plaintiff

proffered an  instruction or  objection clearly giving  the trial

judge  and the  opposing party  notice of  this theory  of claim,

including a  formulation of an acceptable  limit or qualification

to  distinguish  plaintiff's  contention  from  an  argument  for

unlimited jury discretion.   Thus, we  consider the more  extreme

implications of the  unqualified argument to make the  two points

                               -18-


that a limit is essential and that the burden is on the plaintiff

to propose  an acceptable explanation  of that limit  rather than

asking a trial court to leave a jury unguided.

          To sustain appellant's  argument for a new trial on the

procedural  record before us, we would have to determine that New

Hampshire  tort law places no  limit on the  jury's authority, in

reaching  the  jury's  overall  evaluative finding  in  a  strict

liability  case, to weigh all policy arguments (or at least those

policy arguments supported by any evidence received in the trial)

for and against strict liability, in reaching the jury's  overall

evaluative finding in a strict liability case.

          We  cannot  say that  New  Hampshire  has adopted,  and

cannot  predict that it will  adopt, the novel  position that the

jury  has  this  authority.    Allowing  the jury  such  sweeping

authority  would  be contrary  to  premises  so fundamental  that

courts only rarely sense a need to advert to them.

          The  first  of  these  basic premises  of  settled  law

concerns the  role of precedent in  the legal system.   A court's

acceptance  of   an  argument  for   a  literally   "all-factors"

evaluative decision by a jury of a strict product liability claim

would have the effect of delegating to the jury the authority and

responsibility  for  weighing  conflicting  arguments  of  public

policy  bearing upon the scope and limits of strict liability and

striking the  balance that determines the  legal system's answer,

case by case.  This would undermine the  function of precedent in
                      

the  legal system -- to promote evenhanded decision of like cases

                               -19-


alike.  Judicial decisions considering similar arguments for jury

discretion  to weigh  public policy  arguments have  rejected the

idea.   See, e.g., Shackil v. Lederle Laboratories, 561 A.2d 511,
                                                            

528 (N.J. 1989) (the majority, over vigorous dissent, declined to

leave to a jury a public policy choice that, it was argued, would

drive  DPT vaccine  for  infants off  the  market); Bammerlin  v.

determination  whether a  truck  cab  manufacturer complied  with

federal   safety  standards);   Bryant  v.   Tri-County  Electric

the jury, weighed "the public policy goals of protecting consumer

and discouraging the sale  of defective goods" and held  that the

strict  liability doctrine  applied to  the services  of electric

utilities).  But cf.  Dawson v. Chrysler Corp., 630  F.2d 950 (3d

the dangers of  such a case-by-case determination in  the context

of  motor vehicle  safety standards  but declining  to reverse  a

judgment entered  on a verdict  of a  jury that was  allowed very

broad discretion by the trial court's charge).

          A  second   basic  premise  of  settled   law  is  that

determinations of liability (whether under a concept of "duty" or

"cause" or some other terminology  such as "scope of  liability")

are never exclusively "fact"  questions to be decided by  a jury,

or by a judge as factfinder in a non-jury trial.   Even when some

disputed issue of historical  fact is relevant, the determination

                               -20-


of "duty," "cause," or  "scope of liability" is a  mixed law-fact

determination  rather than  exclusively  a fact  question.   See,

707,   708  (1st   Cir.  1989)("Negligence   and   causation  are

traditionally  mixed questions of fact and law."); cf. Milliken &

          When  a jury  participates  in the  determination of  a

mixed-law-fact question,  it does so under  instructions from the

trial  judge  explaining  the  legal aspects  of  the  evaluative

"finding" the jury  makes.  See Kissell v.  Westinghouse Electric

is properly instructed  as to  the law); see  also Chellman,  637

          In the  face of  these settled principles,  no decision

cited to us, and none of which we are aware,  in New Hampshire or

elsewhere,  requires  the submission  to  the  jury  of a  single

                               -21-


evaluative  question determining  a strict  liability claim.   We

conclude  that, in deciding this  appeal in a  diversity case, we

should not  predict an expansion  of strict  liability under  New

Hampshire law to the extent of permitting juries a discretion not

guided by instructions  on the  limits set by  the public  policy

choices,  explicit and  implicit, in  New Hampshire  statutes and

precedents.  Cf. Thibault,  395 A.2d at 847 (indicating  that the

          Remaining  for  consideration  is appellant's  argument

that  even  if  the jury  should  not  be  allowed such  sweeping

discretion, at least appellant  should be allowed a new  trial to

seek a jury finding under an instruction on duty to warn somewhat

more burdensome to  a defendant  than merely a  duty of  ordinary

prudence.  This  issue, however,  is the question  stated at  the

beginning  of this Opinion.  It is the interesting question that,

on federal procedural grounds, we conclude we should not reach in

this case.  Not  having objected precisely on this ground and not

having proposed to the  trial judge an acceptable  instruction to

the  jury on a question that, viewed most favorably to appellant,

                               -22-


is  a  mixed-law-fact  question,   appellant  is  precluded  from

advancing this contention now. 

          Plaintiff's requests  for instruction and  objection to

the  charge,  generously  construed  in  plaintiff's favor,  were

sufficient,  we assume, to  alert the trial  judge to plaintiff's

contention that  a departure from ordinary  prudence with respect

to  warning  and instructions  for use  would render  the product

defective for the purpose  of plaintiff's strict liability claim.

In  its  denial of  the  motion for  new  trial, the  trial court

conceded that its instruction had been in error in this regard.

          Apart  from  this  ground  of  request  and  objection,

however, plaintiff  proffered no form  of instruction on  duty to

warn as part of the strict liability claim.  For this reason, the

request  and objection were  not specific enough  to preserve any

other issue  with respect to the strict liability instruction for

consideration on motion for new trial or on appeal.   See Fed. R.
                                                                   

Civ. P.  51; see also  Jordan v. United  States Lines,  Inc., 738
                                                                      

F.2d 48 (1st Cir. 1984)(holding that appellant's objection to the

trial court's instruction on the definition of  "unseaworthiness"

was not  specific enough to satisfy Rule  51).  Moreover, even in

the brief before this  court and on oral argument,  appellant has

failed  to propose any instruction that would define the issue or

issues  left to be  tried after we  accept, as already  tried and

fairly determined, the issues decided by the jury verdict.

          The  jury findings  (which we  have determined  are not

undermined by any of appellant's attacks) must stand.  And, as we

                               -23-


have noted,  appellant has  not  proffered any  definition of  an

issue, for which there is support in precedent or in reason, left

to  be tried  on new  trial.   To  remand for  new trial  without

providing  any guidance  about the  issue or  issues to  be tried

would be inappropriate.   And, of course, it would  be manifestly

unfair to set aside the fairly determined jury findings and award

a  new trial  without  limitation.   Thus,  we affirm  the  trial

court's denial of the plaintiff's motion for new trial.

                           CONCLUSIONS
                                     CONCLUSIONS

          First.    Plaintiff-appellant's challenges to the  jury

findings on the basis  of the instructions given on duty  to warn

in  negligence are without merit and  the jury findings establish

that plaintiff failed  to prove causal negligence in any relevant

way  (including due care in warning and instructions for use) and

plaintiff failed  to prove that  defendant is strictly  liable on

any ground apart from failure to warn.

          Second.         Plaintiff-appellant's    requests   for

instruction and objection  to the charge on  the strict liability

claim were not sufficient to preserve on motion for new trial and

on  appeal the contention that, under New Hampshire law, the duty

to warn as a part of a strict liability  claim requires more of a

defendant than does the duty to warn in a negligence claim.

          Third.   New Hampshire substantive law does not require

that a product defect  be determined on the basis of an unlimited

all-factors  weighing  by  a  jury,  unguided  by  statutory  and

decisional limitations on the scope of strict liability.

                               -24-


          Fourth.     In light of  these conclusions,  the jury's

verdict in defendant's favor on  the duty to warn as part  of the

negligence claim precludes a finding in plaintiff's favor  on the

duty to warn as part of the strict liability claim, and any error

of  the trial  court with  respect to  the instruction  on strict

liability was harmless.

          Judgment for defendant is AFFIRMED, with costs.
