The opinion of the court was delivered, by
Agnew, J.The learned judge in the court below fell into an error in affirming the 1st point of the defendants that the law presumes a note mailed to the plaintiff at a place where he usually receives his letters and transacts his business, was received by him by due course of mail. A strong probability of its receipt may arise, and as a fact, in connection with the other circumstances, it was right to refer it to the jury. But in their hands it became not a legal presumption binding on them as a rule of law but only a natural probability, as it is termed; that is an inference of fact of the probability of the actual receipt, by mail,of the letter containing the note, arising from all the circumstances *291in evidence. A legal presumption is the conclusion of the law itself of the existence of one fact from others in proof, and is binding on the jury, primá facie till disproved, or conclusively, just as the law adopts the one or the other as the effect of proof. The learned judge was, no doubt, misled by the generality of the language of Mr. Greenleaf, in his Treatise upon Evidence, in relation to letters sent by mail, Vol. 1, § 40. But the authorities cited by him for the statement all refer to notice of the dishonor of bills or non-payment of notes. The necessity of notice of nonacceptance or non-payment and the inconvenience of giving it by special messenger to those residing at a distance, led to the adoption of the post by commercial usage which has settled into law. Hence the remark of the late C. J. Gibson, in Jones v. Lewis, 8 W. & S. 15, that no judge has said the post-office is not a legal place of deposit when the endorser lives in the countyy or at such distance as would make the employment of a special messenger burdensome.
But that this rule is the mere creature of commercial usage and not the result of the general principles of conduct which lie at the foundation of legal conclusions, is rendered palpable by his admission in that case that notice by deposit in the post-office to one living in the same city is insufficient. This was expressly decided at the same term in Kramer v. McDowell, 8 W. & S. 138. There is another class of cases where, by the acts of the parties, the mail is made the vehicle of their communications, as where a proposition by mail is accepted by the same channel. But by no law of the United States in reference to the mails or of the state is the post made a legal channel of communication which a party may adopt and make compulsory upon his correspondent. It was error, therefore, to hold that the law concludes that the note was received by the plaintiff, from the mere fact of a deposit of it in a letter mailed at a distant office, directed to him at the place where he usually received his letters and transacted his business. The purpose here was to show payment of the note. This was done by the production of the note itself, without a receipt or mark of payment or cancellation upon it, and without any evidence of its delivery to the plaintiff except the deposit in the mail. Payment was, therefore, to be proved by a double presumption at law, first, the legal presumption of delivery from the deposit in the joost-office, and, secondly, the presumption of its return into the hands of the drawers by delivery on payment.
Now, while the facts, when all collected by the jury, might have satisfied them that the note was actually in the possession of the plaintiff, by receipt through the mail, and found its way back into the hands of the defendants by their payment of it; it certainly was erroneous to instruct them that the possession of the *292note by the plaintiff was a conclusion of law from the fact of mailing it to him.
The judgment is therefore reversed, and a venire facias de novo awarded.
