Woolley, J.,
charging the jury:
Gentlemen of the jury:—This action was instituted by the plaintiff against the defendants upon a promissory note, made by *501the latter to the order of the former, whereby the plaintiff seeks to recover from the defendants the sum of two hundred and fifty-nine dollars and ninety-two cents, the principal of the obligation, with lawful interest thereon from the fifth day of October, A. D. 1912, together with the sum of.one dollar and seventy-one cents protest charges. The plaintiff proves that the note was given in payment of the purchase price of a mare and a rake, sold by the plaintiff and purchased of her by the defendants at a public vendue, held upon her premises in this county on the fifth day of October, A. D. 1912; that the price of the mare was two hundred and forty dollars and the price of the rake was eight dollars, the difference between the aggregate of the two sums and the face of the note being the interest added; that the note was protested and the sum demanded remains unpaid.
The defendants admit the purchase of the mare and rake at the prices stated, and that the note was given in payment therefor, but for defense avail themselves of the terms of a statute of this state, Chapter 588, Volume 20, Laws of Delaware, which provides “that want or failure in whole or in part of the consideration of bills and notes for the payment of money may be shown as a defense total or partial,” when, as in this case, the action is between the original parties thereto, and in proof of a total failure of the consideration of the note, maintain, that the mare was sold by the plaintiff under an express warranty of her soundness, that at the time of the sale and for a period theretofore and until thereafter returned, the mare was unsound, which condition was discovered by them shortly if not immediately after receiving her, that they promptly acquainted the plaintiff with the condition of the mare, by notifying the plaintiff in person the day after the sale and twice later by informing her son, who it is claimed had at the vendue announced the mare to be sound, and as the mother’s agent represented her in the transaction, that the mare was sick, and after caring for and doctoring the mare from the date of purchase until the thirtieth day of March following, working her as it is claimed, but two times during this interval, they returned her to the plaintiff. Upon this representation of facts the defendants maintain there is a total failure of the considera*502tian for the note, in that the contract of sale was vitiated by a breach of the plaintiff’s alleged warranty of the soundness of the mare and that by way of recoupment, the defendant sustained damages in the manner testified to and to an amount in excess of the total of the plaintiff’s demand against them upon the note, for money laid out and expended in the care of the mare, the cost of her keep, medical attendance, medicines, etc.
In reply, the plaintiff maintains that in the sale of the mare, neither she nor any one with her authority warranted the mare to be sound; but if it should be found that by expression or implication, such a warranty may be attributed to her, then in fact ' the mare was sound at the time of the sale and consequently she committed no breach of warranty as claimed by the defendants.
[1] The plaintiff maintains that under the statute which permits the maker of a note to show a partial or total failure of consideration of the note, when sued upon, the maker of the note may not include and embrace therein the elements of damage that may be consequent therefrom and accumulate in respect thereto, even though the same may be included and recovered in a counteraction upon the same matter, “instituted by the maker against the payee. This we do not believe to be the law, as the obvious intent of.the statute is not to permit the maker of a promissory note to vary the terms thereof, but when sued thereupon by his original promisee, to enable him to make the same claims or demand with respect to the matter that constituted a want or failure of consideration of the note, as he could have made, if he himself had instituted a suit against the promisee on the same matter out of which the consideration of the note arose. If in this instance, no note had been given for the purchase price of the mare, and the plaintiff had sued directly on the contract of sale, the defendants could have replied a breach of a special warranty and have recouped in damages. Obviously then, they may attempt the same thing in defending upon the note upon the want of consideration.
[2] There is in this case no dispute as to the sale of the mare. This is admitted. There is however, a dispute as to the terms of the sale, and from the controversy that revolves thereabout, you *503are to extract the truth. For this truth you are to reach into the testimony, of which you are the sole and exclusive judges and which by the Constitution of this state we are forbidden to consider or discuss with you. In seeking the truth, that is, what constitutes the true and precise terms of this sale and the compliance or violation thereof by all the parties, you are to reconcile the testimony if jmu can, and if you cannot you are to accept that testimony which you consider to be most worthy of belief and reject that which you consider least worthy of belief, having regard to the intelligence, interest and bias of the witnesses and their capacity and inclination to see, and understand and remember that to which they have testified.
The first question for you to consider and determine is whether the sale of the mare was made with a warranty as to her soundness. If, at the time of the sale, there was no warranty as to her soundness made by, or with the authority of, the plaintiff, then the defendants purchased the mare at their own risk. If they made the purchase at their own risk, there is then no failure of a consideration of the note, and your verdict should be for the plaintiff for the principal, interest and protest charges proven.
[3-6] If you find that at the time of the sale there were representations made by the plaintiff or by one authoritatively acting for her, as to the mare’s soundness, you are next to determine whether they amount to a warranty. Whether the plaintiff in this case, who is the mother of the son managing the sale, authorized the son to make the warranty, is to be gathered or it may be implied, from the general authority which she permitted him to exercise in managing her sale. No particular words or formula are necessary to create a warranty. Every affirmation made by the vendor or her qualified agent at the time of sale, as a fact and as an inducement to the sale, if the buyer relies thereupon, amounts to a warranty. Whatever representations are made by the seller at the time of the sale as to the quality of the thing sold is generally held in law to amount to an express warranty. Any disease or infirmity of the mare not visible and palpable at the time of the sale which impaired her usefulness, would render her not sound, and whether known to the plaintiff or not would constitute a

*505[7] 1. The defendants must prove an express warranty, viz.: that the plaintiff expressly stated that the mare was sound, or represented her as a sound mare, or that such representations as to soundness were made by some person acting under the authority of the plaintiff. These representations must have been made either just before or at the time of the sale.
2. If the defendants have proved the contract of warranty, they must next show the breach thereof. They must prove that the unsoundness existed at the time of the sale. Any disease, infirmity or defect which then rendered the mare less fit for present use and convenience, and not openly and palpably visible, and which is discoverable only by persons of skill and judgment, in regard to the qualities of horses, constitutes unsoundness. They must also show that the leg did not “come right”.
[8] 3. The third thing that must be proved is damages.
It is the right of a party to a contract under certain circumstances to rescind it. And in order to avail himself of the right of rescission, it must be done in a certain way. It is usually done by the return and delivery of the thing purchased, which delivery must be made within a reasonable time. In this particular case it is alleged that the mare was returned by the defendants to the plaintiff. It is contended by the defendants that the return was a good delivery, and it is contended by the plaintiff that it was no delivery at all. It is for you to decide whether it was a delivery. In law a delivery is the transmission of property from one person to another. That is the physical part of it. And the legal part is that it must be done as quickly as can be done under the particular circumstances of the case. There is no rule with respect to delivery that will apply in every case. You have heard the situation of the plaintiff when she sold the mare. You have heard of her change of residence between the time that she sold the mare and the time the mare was attempted to be returned to her. It is for you to decide whether or not when the defendants undertook to return the mare to the plaintiff they did it in as reasonable and as practicable and sensible a way as they could under the situation in which they found themselves with respect to the plaintiff.
*506We say to you that the best delivery is the physical return of property to the person to whom it is intended to be returned. If I hand you a bucket, I deliver the bucket to you from my hand to your hand, which is a complete delivery and there can be no question about it; but a manual delivery to a person to whom the delivery is attempted cannot always be made, because it is made impossible at times by the change of residence, change in circumstances of health, sickness, physical presence or physical absence of the parties—all of those things vary the ability of one person to return or deliver the property to another person. Therefore, it is for you to decide in this case as to the act and fact of delivery, whether under the circumstances of this case the defendants returned the mare into the possession of the plaintiff as well as they could under the circumstances of the plaintiff’s residence on the farm, and their ability to deliver such a thing as a horse.
[9] The next question for you to determine is whether the mare, if returned, was returned within a reasonable time. What will constitute a reasonable time within which to rescind a contract, is usually a matter of construction of the contract and is therefore a question of law for the court and not for the jury. When, however, it develops that the terms of a contract are in dispute and being in dispute are uncertain and unknown until determined by the jury, then construction of the disputed terms of the contract cannot be made by the court and in such cases of dispute the question of what are the terms of the contract, and the reasonable time for an act thereunder, for instance, the terms of a warranty and a reasonable time for rescission, or the time for delivery and a reasonable time to replace goods not delivered under a contract of sale, are often questions proper and necessary to be determined by a jury under the circumstances of the case. Love v. Barnesville Mfg. Co., 3 Penn. 152, 156, 50 Atl. 536; Barnesville Mfg. Co. v. Love, 3 Penn. 570, 571, 52 Atl. 267.
[10] The warranty alleged in this case is unusual in that it is twofold in its nature, extending as it is claimed to the general soundness of the mare as against invisible defects, and to the recovery of an unsound leg, which was a visible defect. If you find there was no warranty for the recovery of the unsound leg, *507it was the duty of the defendants to have returned the mare to the plaintiff promptly and immediately upon the discovery by them that the mare was not as otherwise warranted. Anything else would constitute unreasonable time.
If, however, you find there was, in addition to a general warranty of soundness, a warranty that an injured leg “had to come right”, the defendants were entitled to keep the mare under the latter warranty for such time as under the circumstances would be reasonable for the leg to get better or worse. This latter warranty, assuming both warranties to have been made as claimed by the defendants, justified the defendants keeping the mare for a time longer than, without it, they would have been justified in keeping the mare under the terms of the general warranty as to soundness. There being in this case a conflict of testimony not only as to the existence of the warranties, but also as to their terms, and there being a dispute as to whether one warranty was related to the other so as to affect the reasonableness of the time within which rescission should have been made, we consider that this is not a case in which the court can determine as a construction of the contract, because of lack of certainty as to its terms, whether the rescission was made within a reasonable time after a breach of the warranty, but is a case in which that question should be submitted to you, gentlemen of the jury.
[11] A sale properly rescinded is substantially like one never made or completed, and when the buyer of a mare makes a proper and timely rescission of the sale, the seller is liable to the buyer under notice of recoupment, in an action for the purchase price, for the expense of keeping the mare and for all consequential damages caused by the breach of warranty. Webster v. Beebe, 1 Boyce 318, 76 Atl. 54; Williston on Sales, p. 1021; Hillard on Contracts, Vol. 2, p. 195.
[12] If the plaintiff or her agent induced the delay in the return of the mare by statements to the defendants, the plaintiff has then waived her right to have the mare returned within the time that first might be considered reasonable, after the defendants discovered that she was not sound.
If you believe that the defendants lawfully and properly *508rescinded the contract of sale for the mare, then the plaintiff is not entitled to recover the two hundred and forty dollars, the purchase price of the mare, with eight months’ interest; and if you believe that the defendants have proven damages sustained by them as a result of the breach of warranty equal to or in excess of the balance of eight dollars and.interest due on said note, your verdict should be for the defendants. Benson v. Wilmington City Ry. Co., 1 Boyce 207, 75 Atl. 793.
If you should find that the defendants made a legal return and delivery of the mare to the plaintiff because of a breach of the plaintiff’s warranty as to the mare’s qualities, the plaintiff cannot recover against the defendants, but as against the claim of the plaintiff, by reason of the statute, you may set off the sum of two hundred and forty dollars, the price of the mare, and such damages consequential upon the alleged breach of the plaintiff’s warranty as may have been proven up to the amount of the plaintiff’s demand on the note, but not in excess of it.
If, however, you find that the defendants did not make a delivery of the mare to the plaintiff, under the law as we have instructed you, then we say to you that the defendants may still defend upon the ground of the alleged breach of a warranty, and if you find that the mare was not sound as warranted, then you may set off against the demand of the plaintiff on the note given for the purchase of the mare, which is the two hundred and forty dollars, such an amount of money as you find represents the difference in value between the mare as sound and the mare as unsound.
Verdict for plaintiff.
