Opinion by
Mr. Justice Potter,February 21,1910:
The defendant in this case sold to the plaintiff a gas engine, warranted to develop under certain conditions a specified amount of power. Plaintiff received, used and paid for the engine, but claimed that it never worked in a satisfactory manner, and that it would not under any circumstances produce the stipulated amount of power. This action was brought to recover the damages resulting from the alleged breach of the warranty. The trial resulted in a verdict for the plaintiff for $3,745.42, and from the judgment entered upon this verdict, the defendant has appealed. Nine assignments of error have been filed. The first specification violates rule 31, as it does not contain, a reference to the page of the paper-book where the matter complained of may be found in the printed evidence. This assignment must therefore be dismissed: Downey Bros. v. Penna. R. R. Co., 219 Pa. 32. The second, third and fourth assignments are to the charge of the court, and the sixth and seventh complain of answers to points submitted by defendant. The record shows no exception taken *317at the trial, either to the charge, or to the answers to the particular points referred to in these assignments. For this reason they cannot be considered: Sibley v. Robertson, 212 Pa. 24; McConnell v. Penna. R. R. Co., 206 Pa. 370. Counsel recognized the force and effect of the rule at the argument, and did not press the assignments in question.
Defendant’s fourth point recited that in plaintiff’s statement no claim had been made, as an item of damages, for the difference in value between the engine delivered and that which was purchased; and as defendant maintained that under the evidence this was the only proper measure of damages, it was contended that no recovery could be had. The refusal of the fourth point is made the subject of the fifth assignment of error. It is true that plaintiff’s statement of claim does not plainly define the cause of action, and does not make it clear whether the plaintiff intended to rescind the contract, or to claim in affirmance thereof. But as the fourth point presented by defendant asks for binding instructions in its favor, it was not error to refuse it. If there was a breach of its warranty, the defendant was bound to respond in damages to the plaintiff to the amount of the difference in value between the engine furnished, and that which it contracted to supply. As the trial judge states in his charge, the evidence shows no attempt upon the part of the plaintiff to rescind the contract. Its whole course of action showed a positive affirmance or ratification of the contract. It kept the engine, and used it more than two years, and is therefore only entitled to recover the damages arising from the breach of the warranty. Under such circumstances, the measure of damages is the difference between the value of the article as warranted, and the real value of that which was furnished: Seigworth v. Leffel, 76 Pa. 476; Himes v. Kiehl, 154 Pa. 190. The learned trial judge evidently had this rule in mind, for he said to the jury, “The most that the plaintiff can recover upon the element of price, if it is entitled to recover damages in this case, would be the difference between the contract price, and what was the value of the machine, such as it was.” But he did not stop with this, and in another part of his charge, he permitted the jury to *318take into consideration as part of the-damages; the alleged loss of productive power in the factory, owing to the decrease in the power of the engine. This could mean nothing less- than loss of profits in the business, and would be too remote and uncertain an element for proper consideration by the jury, in estimating the damages.
Counsel for appellant further allege, in the ninth assignment, that the trial judge erred in permitting plaintiff’s counsel, against objection, to send out with the jury a statement and calculation prepared by counsel, for the purpose of indicating to the jury, the amount of the verdict to which he thought the plaintiff was entitled. The record does not show what the statement contained, except as to one item of $2,500 for the difference between the value of the engine received, and another. We do not find anything in the evidence to support this estimate, or indicate the actual value of the engine and producer which was furnished. The point raised by this assignment seems to fall directly within the ruling in Himes v. Kiehl, 154 Pa. 190. The cause of action there was similar to the one before us now, and it was there held that the measure of damages was (p. 196): “ The difference between the actual value of the engine as it was at the time of the sale and its value if it had been as warranted.” The trial judge in that case per-' mitted a statement to be sent out with the jury which contained the following: “Difference between actual value and guaranteed value — $150.” This action by the court was held to be error, and it was pointed out that the matter in dispute was not represented by any fixed sum, but was essentially a matter to be determined under all the evidence, and by the jury alone. So in the present case, the claim being for unliquidated damages, the fixing of the amount was a question peculiarly appropriate for the judgment of' the jury, under the evidence. In Quinn v. Transit Co., 224 Pa. 162, we said (p. 165): “ It is error for counsel to state to the jury the amount of damages claimed in the declaration. The damages are to be ascertained by the jury from the evidence, and are not to be determined by any estimate of counsel not based on the evidence. Any suggestion to the jury of the arbitrary amount *319in which the damages are laid, in the declaration, is highly improper: Reese v. Hershey, 163 Pa. 253.” It must be manifest that it would be equally injurious for counsel to hand to the jury a written statement, as was done in this case, containing at least one large item which was merely his own estimate of the amount of the damages sustained by his client in that particular, but which was not supported specifically by the evidence. Counsel for appellee in his argument suggests that the $2,500 item was excluded from the statement; but if it was, the record fails to show it. Rather does it appear that the entire statement including this item, was sent out with the jury, with the instruction from the trial judge that the jury were not to regard the statement as evidence, but as “merely the counsel’s argument.” We do not regard this as sufficient to cure the mistake, or to overcome the effect of the error.
The judgment is reversed with a venire facias de novo.
