The plaintiff’s only objection to the reception of Day’s mortgage in evidence is, that it was not admissible under the defendant’s answer. His answer alleged that the replevied goods were his property, and not the property of the plaintiff. And as it was not necessary that he should set forth in his answer the evidence of his property in the goods, in order to render such evidence admissible on the trial, the objection cannot be sustained.
Nor can we sustain the objection to the admission of the defendant’s testimony as to his taking possession of the mortgaged goods, and the disposition made of them, before Day (the mortgagor) was in default. Although, by the terms of the mortgage, Day had a right to keep possession of the goods, and use and enjoy them, till he should be in default, yet he might waive that right and any other right reserved to him by the- mortgage, and make a new agreement with the defendant (the mortgagee) for any lawful disposition of the mortgaged goods. And it is not a legal objection to the validity of such new agreement, that it is not in writing. Chit. Con. (10th Amer. ed.) 115, and cases there cited. See also Shearer v. Babson, 1 Allen, 486.
The argument for the plaintiff assumed, what the bill of exceptions does not distinctly show, that the oral agreement on which the parties to the mortgage acted was made before the mortgage was executed, and was therein merged and thereby annulled. But if we were to adopt the plaintiff’s assumption, it would not avail him. A waiver may be shown by acts or by omission to act, as well as by express agreement. And though one oral ■ agreement may be annulled by a written one, yet another may be afterwards made, in the same terms, and will operate as a waiver of provisions in that written agreement, to the same extent as if no previous oral agreement had been made. Upon the testimony in the present case, the court have no doubt that Day, after the mortgage was made, by his acts, if not by express agreement, waived the right of retaining the exclusive possession and control of the mortgaged goods. *321Whether, if it had appeared that the defendant wrongfully took possession of the goods, in violation of Day’s rights, the plaintiff could have been entitled to maintain this action, is a question on which no opinion is required.
Evidence was rightly admitted that Day, at the time when he made the mortgage, was in good pecuniary credit in his neigh borhood. Bartlett v. Decreet, 4 Gray, 111. Heywood v. Reed, 4 Gray, 579, 580. Carpenter v. Leonard, ante, 32.
We are of opinion that the plaintiff has no legal ground of exception to the instruction given to the jury concerning the proof which it was necessary that he should produce in support of his action. The remark of the judge that there should, on the evidence, be “judicial certainty” that the mortgage was made in fraud of the insolvent laws, might have been objectionable, if it had not been explained by him. But he forthwith, and in the same sentence, stated to the jury what he meant by judicial certainty, to wit, that they were to be reasonably satisfied that the defendant had reasonable cause to believe the insolvency and fraudulent purpose of Day, &c. This rendered the instruction unexceptionable.
Exceptions overruled.
