clearly entitled to the one or the other. She owed the bank nothing, and put up the $2,000 merely to obtain the bonds, which had previously been transferred to her. Assuming that the bank, according to the terms of the collateral note, had the right to retain the bonds until the other obligation held by it against Elias August was paid (
Bank v. Strever, 18 N. Y. 502 ; Bank v. Hall,
83 N. Y. 338 ; Hutchinson v. Manhattan Co.,
150 N. Y. 250 , 44 N. E. 775 ; Gillet v. Bank, 160 M. Y. 549, 55 N. E. 292 ), it should have corrected her understanding of the arrangement by asserting this right, and declining to receive the plaintiff’s money impressed with the condition upon which she paid it. The bank had no right to obtain the money of the plaintiff, a stranger to the original contract, and then refuse performance of the condition upon which the money was obtained. The law will not countenance this mode of doing business, nor allow any one to profit by sharp dealing, but will hold the bank to methods more conformable to fair dealing and proper business principles. It must be held that, if the bank had the right to retain the bonds until the other obligation of Mr. August was first paid, such right was, on principles of equitable estoppel, waived, as to the plaintiff, when it took her money with knowledge that the money was paid only in consideration of a relinquishment of all claim of the bank upon the bonds. The plaintiff certainly expected to get the bonds, and the bank officials took her money knowing that she parted with it upon the belief that the bonds would be surrendered, and that the bank had agreed to surrender them. By their conduct the bank officials assented to the plaintiff’s understanding of the agreement, and cannot keep her money, and repudiate the understanding on which they knew she paid it. This would seem to accord with every notion of substantial justice and the principle that, “where the language of a promisor may be understood in more senses than one, it is to be interpreted in the sense in which he had reason to suppose it was understood by the promisee.” Hoffman v.
