delivered the opinion of the court.
This action was commenced by attachment upon sundry notes, issued by the defendants as bank notes, and which they had refused to redeem, on presentation, in gold or silver, as they were bound to do by their charter.
Some moveable- property was attached, and William M. Beal, the agent of the defendants in New-Orleans, was cited as garnishee, and required to answer interrogatories. An attorney having been appointed by the court to represent the *488absent defendants, the case was submitted to a jury, who gave a verdict in favor of the plaintiff for the amount claimed, and eight per cent, interest, agreeably to the laws of the state of Mississippi. The defendants’ counsel having failed in his attempt to have the verdict set aside and a new trial granted, judgment was entered against them, and they appealed.
The -competency of a witness, or his in-terestin the matter in controversy, may be ascertained by examining him on his voir dire; if the party objecting does not choose, to do this, the party offer i ng hi m may rebut the presumption of his incompetency by other evidence. The partner of a firm, subscribed as security to an attachment bond, who was absent when the name of the firm was signed, is primó, facie, a competent witness to testify in the case.Two bills of exception were taken on the trial by the defendants’ counsel. 1st. To the opinion of the court admitting George W. Huntington, as a witness, on the ground that he was a partner of the firm of Wilcox, Anderson & Co., which firm was designated by the judge as the security of the plaintiff on .the attachment bond, and had subsequently signed said bond.
2d. To the opinion of the court, admitting a witness to prove that the signature of Wilcox, Anderson & Co. on the bond was in the handwriting of Wilcox, one of the partners; that Huntington was absent from the state at the time the bond was signed; and that the act of partnership does not authorize the signing of such bonds.
The judge did not err in overruling these exceptions. When the witness Huntington was offered, the defendants’ counsel might have ascertained, by examining him on his voir dire, whether he had any interest in the controversy. If the defendant’s counsel did not think it safe to do so, the plaintiff had the right to rebut, by other evidence, the presumption which the signature of Wilcox, Anderson & Co. to the attachment bond created against the competency of the witness. The fact that he was out of the state, and that he did not sign the bond, made him prima facie a competent witness ; and if he had assented to or ratified the act of his partner, the defendants’ counsel was bound to prove it, but has not attempted to do so. It was not necessary to prove that the act of partnership did not authorize the signing of the bond ; we are bound to presume that it did not, until the contrary is shown.
Before pleading to the merits, the defendants’ counsel excepted to the action on the ground that the notes sued *489upon had been transferred to the plaintiff by the person who presented them to the bank; that they had been put anew in circulation by this transfer, and that no demand was averred to have been made by the plaintiff.
Bank notes when presented at the bank and payment refused, become mere evidence of debt, fluctuating in value according to the credit of the bank, and are fair subjects of trade and commerce. Trading in them is not putting them in circulation anew, so as to do away with the original demand and the effect of non-payment.This exception was overruled, and although it was earnestly pressed upon us in argument, it appears to have been abandoned in the court below. However this may be, it cannot avail the defendants. It is proved that the notes were presented at the bank, and payment refused. When they ceased to be convertible into gold or silver, they lost the character of bank notes, and became mere evidences of debt, which fluctuated in value as the reputation of the bank for solvency increased or diminished. While this state of things lasted, they were fair subjects of bargain and sale. Trading in them was not putting them in circulation, and the plaintiff, under his purchase, acquired them with all the benefits and advantages which had vested in the previous holder, by the fact of his demand of payment. Upon the merits, the verdict and judgment are fully supported by the evidence, and must be affirmed.
It is, therefore, ordered, adjudged and decreed, that the judgment of the Parish Court be affirmed, with costs.
