*79By the Court,
Mosher, J.:The questions upon which the Court is called to pass, arise upon the admission of testimony and the instructions given and refused by the court below. I will consider these in the order in which they appear in the bill of exceptions.
Mrs. Dr. Thompson and Dr. Hanchett, being called on the part of the State, testified that the deceased had applied to each of them on the subject of her pregnancy. To this evidence the defendant excepted.
• In order to sustain the indictment, it became necessary for the State to establish the fact of the pregnancy of the deceased at the time she went to Glass’s house. The representations of a sick person, of the nature of the malady or the bodily feelings under which he is laboring at the time, especially if made to a medical attendant, are always received as original evidence.
As stated in the case in 9 Cushing, cited by defendant, the res gestee are different in different cases; and it is not perhaps possible to frame any definition which would embrace all the various cases which may arise in practice. The statements of Mary Hardman, made to her physician concerning her condition, are free from those objections which usually apply to the admission of hearsay. They were in the nature of a confession. They were made against every possible inducement to suppress, conceal or distort the truth; when modesty and shame protested against their utterance, and when the perils of her situation persuaded her to speak. It would be impossible not to distinguish a case of this class from those referred to in the cases cited by defendant, where persons have sought to avail themselves of their own declarations to influence verdicts in which they had a pecuniary interest.
Dr. Watkincls, having testified that his examination of the uterus was sufficient to enable him to tell whether the deceased died from hemorrhage or other causes, was asked the question, “What, in .your opinion, caused the death of the person from whom the uterus was taken?” The witness answered, “She died from hemorrhage caused, by the re*80moval of a foetus.” This question was objected to, for the reason that the answer would involve the point which the jury had to determine. "We think the objection not well taken. In order to ascertain the guilt or innocence of the defendant, it was necessary to ascertain the cause of the death.
It is true that general opinion of scientific men is regarded by some writers as a very unsatisfactory kind of evidence, and judges in many cases have received it with the utmost caution, but no inflexible rule has ever been laid down upon the subject. It has been truly said that scientific evidence is generally a matter of opinion, and a form of questions calculated to exclude opinions will often have the effect to destroy this class of evidence altogether. The' objection urged to scientific testimony is not so much to the form of the examination as to the uncertainty of scientific tests. In a large number of cases cited in Wills on Circumstantial Evidence, the opinions of medical witnesses were received. The better opinion seems to be that the form of the interrogatory is a question addressed to the discretion of the court, subject to such considerations as the nature of the particular matter under examination, and the character and ability of the witnesses. It appears that the testimony in question was but a small part of the expert testimony going to show the causes of the death. A number of medical men, whose character and ability are unquestioned, testified without objection to particular facts from which the jury could infer the causes of death. Some of these witnesses had assisted at the post-mortem examination of deceased, others had subjected the uterus to careful microscopic examinations, and their means for becoming acquainted with all the facts accessible in a case of this kind were ample.
On the trial the defense called Mrs. Mealey, wife of Charles Mealey, who was jointly indicted with defendant, and offered to prove statements made by Mealey at the time of leaving Albany with deceased, as to his purpose in going to Portland. This testimony was objected to, and the objection, we think, properly sustained. The appellant had obtained a separate trial, and we are unable to see how his *81case could be in anywise affected by proving Mealey’s declarations of his intentions at some time previous to any meeting between them. “Declarations to become part of the res gestee must have been made at the time of the act done which they are supposed to characterize.” (1 Greenleaf, note 1, § 108.)
- Mealey’s declarations made to his wife prior to his meeting with the defendant and to the performance of the act complained of, have no connection with that fact, which is the principal fact under investigation. These declarations are removed to a remote distance from the principal fact, and are separated from it by a number of circumstances and hypotheses having a doubtful bearing upon the main question. Théy were not part of the res gestee, and were therefore properly excluded. The condition of deceased as to pregnancy was a proper subject of inquiry. If she left Albany to go to Portland, intending to employ a physician to procure an abortion, it was proper that that fact should go to the jury for the purpose of Showing her pregnancy. This evidence was not objected to on the trial, and if liable to objection, it is too late to raise the objection now.
The court refused to instruct the jury that “the hypothesis contended for by the prosecution must be established to an absolute moral certainty, to the entire exclusion of any other hypothesis being true, or the jury must find the-defendant not guilty.” The instruction was properly refused. Absolute moral certainty is not attainable by the human mind. It is a well-understood and long-established rule, that in criminal cases the guilt of- the accused must be established “beyond a reasonable doubt.” Absolute moral certainty excludes not only reasonable doubt, but all doubt. It describes a fixed and uncompromising attitude of the mind, of which men are not capable in any of the situations in life. It means such a degree of certainty as precludes the possibility of error or mistake, and as presupposes the infallibility of witnesses and jurors. It imposes such conditions upon the administration of justice as would make the punishment of crime impossible, and the existence *82of criminal courts useless. Tlie law upon this subject, as laid down by the court, is contained in the three following instructions:
“It is not sufficient that the circumstances proved, coincided with, account for, and therefore render probable, the hypothesis sought to be established by the prosecution, but they must exclude to a moral certainty every other hypothesis but the single one of guilt, or the jury must find the defendant not guilty.”
“When a criminal charge is to be proved by circumstantial evidence, the proof ought to be not only consistent with the prisoner’s guilt, but inconsistent with every other rational conclusion.”
“Circumstantial evidence, to be sufficient for a conviction in this case, ought to be of a conclusive tendency; that is, its tendency ought to be, not only to convince the minds of the jury of the guilt of the defendant, but to exclude the supposition that the deceased destroyed her own life, either directly or indirectly, as the result of an abortion produced by herself.”
We are satisfied that the rule is here' stated as strongly in defendant’s favor as the law will permit.
The court was asked to instruct the jury that all the circumstances, in the chain of the State’s evidence, must concur in showing defendant’s guilt. The true rule was undoubtedly laid down in the case of Commonwealth v. Webster (5 Cush. 296, 318, 317 and 319); Each fact necessary to the conclusion sought to be established, must be proved by competent evidence, beyond a reasonable doubt. It is only required that “the circumstances, taken together, must be of a conclusive nature, and leading on the whole to a satisfactory conclusion and producing in effect a reasonable and moral certainty that the accused committed the offense charged.”
In Summer v. The State (5 Black, 579), it was said that if the jurors have a reasonable doubt as to any one of the circumstances in the chain of evidence, that one circumstance ought not to have any influence in making up their verdict. The jury may exclude any fact from their consid*83eration, ancl it is sufficient, if from the facts which are considered, their minds are drawn to conclude, to a reasonable and moral certainty, that the defendant is guilty. Nor does there appear to be any material difference between the instructions asked for and those given. The jury were instructed that to establish a charge, by circumstantial evidence, it was necessary that the proof should not only be consistent with the prisoner’s guilt, but inconsistent Avith his innocence. This language would not have been strengthened had the court said that all the circumstances necessary to the conclusions sought to be established must be consistent with the hypothesis of guilt and inconsistent with that of innocence. If a single material fact, “ or necessary circumstance,” remained unproven, or having been proven, was inconsistent with the theory of guilt, the crime was certainly not proven with that certainty which the law requires and which the instructions given required.
The court instructed the jury that if they believed, from the evidence, “that the child may have died, or been killed, in the womb of deceased, without any act or assistance on the part of the defendant, and defendant may have injured deceased and wounded or bruised her womb with instruments or otherwise, while in good faith endeavoring to assist nature in the delivery of such dead child, or in the delivery of the afterbirth of such dead child, then the jury must acquit.” It is insisted, by defendant, that it should not have refused to add to this instruction the words, “And the State must show, beyond a reasonable doubt, that none of these hypotheses may be true, to convict,” as it was requested to do by defendant’s counsel. To say that the hypothesis consistent with innocence may be true, contemplates the merest possibility of its truth, however remote, and it is equivalent to saying, “If you find there is a possibility of the innocence of the defendant, he is entitled to an acquittal.” The question was not, may either- of these hypotheses be true, or, in other Avords, is it possible for any of them to be true. The real question was, are you satisfied, beyond a reasonable doubt, that the hypothesis of the prosecution is the true one ?
*84The instruction as given by the court is open to the objection which I have just considered, and it substantially gave to the defendant the benefit of a possibility of innocence by instructing the jury to acquit if they found that the child may have died without defendant’s act, or that he may have injured deceased while in good faith endeavoring to assist nature in the delivery of the child. The law does not decide upon possibilities, but upon such probabilities as appear from the facts, judging by human experience, to be reasonable, and as leave the mind free from reasonable doubt.
It is urged by the defendant that there was no evidence whatever to the effect that defendant advised, aided or assisted any other person in the commission of the crime, and that the court had no right to instruct the jury upon a state of facts which did not exist. The evidence, as disclosed by the record, was circumstantial, and the jury might infer from it either that defendant performed the act charged as constituting the crime, with his own hand, or that he aided or encouraged deceased in doing it. The instruction was, therefore, proper. It is further urged that it justified the conviction of the defendant upon proof that the act charged was not necessary to preserve the life of the mother, whereas he ought not to be convicted if he performed the act believing, under appearances that wrould ordinarily produce such a belief in a competent person, that it was necessary to preserve the life of the mother. This instruction describes the offense precisely as the statute describes it. The real point to which the minds of the jury were directed by. it is that just examined, to wit, that he who aids or encourages the commission of a crime is as responsible as though he committed it with his own hands. The objection, however, having been made to other instructions of the court below, will be examined.
The guilty intent of defendant is presumed if the statutory ingredients of the crime are shown. The mind of man can only be explored by weighing his conduct. It devolved upon the State to show that the removal of the foetus was not necessary to preserve the life of deceased, and the de*85gree of certainty with which this is required to he shown is such that no competent person can be presumed to have believed the act necessary. In this case, had the jury found that the circumstances were such as to induce in a competent person a belief that the removal of the foetus was necessary, or had the testimony left that fact in doubt, this would have been sufficient to create a reasonable doubt in their own minds as to the necessity of the act, and the prisoner must have been acquitted.
A case might arise where there were circumstances at the time of treatment calculated to lead to a conclusion which subsequent developments would show was erroneous; but this is not such a case; and the court may refuse to instruct the jury where there is no testimony to which such instruction can apply. There was no attempt made to show, nor was there anything tending to show, that the act charged as a crime was, or appeared to be, necessary to preserve the life of the deceased. The theory of the defense was, that defendant had no agency in the removal of the foetus, and not that its removal was, or was thought to be, necessary to save the life of the mother. This is shown by the testimony contained in the transcript, where it is attempted to be shown that deceased procured her own death by the use of drugs prior to her meeting with defendant. More than this, every fact relied upon by the prosecution to show the act unnecessary was within the reach of defendant, if he is a competent physician, at the time he treated deceased.
The court was asked to instruct the jury that if they found that deceased had formed and expressed a design to relieve herself of her pregnancy, at the risk of her life, and that, before or after coming to stop with defendant, she may have endeavored to carry such design into effect without defendant’s knowledge or acquiescence, they must find defendant not guilty. Under such an instruction, the jury would have been • precluded from finding the defendant guilty, however conclusive the proof of guilt might be, by proof of an attempt by deceased, at some prior time, to commit the crime. It is immaterial whether deceased, prior to the commission of the crime, made an attempt upon her*86self or not, unless such an attempt contributed to her death.
Counsel for defendant ashed the court to instruct the jury that the declarations of standard medical books in reference to the effect of certain drugs, were entitled to more respect thaD the opinions of medical men who admit that they never used such drugs. There is nothing to show that medical books were offered in evidence.
Other grounds of error assigned in the bill of exceptions were not insisted upon. The charge and rulings as a whole were a fair exposition of the law governing in this class of cases, and' the prisoner does not appear to have suffered in any of his substantial rights. It was said by Lord Kenyon that “the natural leaning of the mind is in favor of prisoners; and in the mild manner in which the laws of this country are administered it has been a subject of complaint that the judges have given way too easily to formal objections in behalf of prisoners,” and this remark applies with peculiar force to our own country and times.
In the language of Mr. Chitty, ‘1 in criminal cases, where the public security is so deeply interested in the prompt execution of justice, it seems the minor consideration should give way to the greater, and technical objections be overlooked, rather than the ends of society defeated.”
We are of opinion that there was no error which could have prejudiced the defendant, and the judgment of the court below must be affirmed.
