Bajrtol, I.,

delivered the opinion of this court:

The cause of action in this case is a promissory note, drawn by E. C. Leitch & Co., in favor of Sewell, Januey & Owens, and endorsed to the plaintiffs.

The suit was instituted, against, Leonard C. Leitch and Daniel Kent, the former of whom was returned “non estP The defendant, Kent, pleaded in abatement the non-joinder of a certain Richard G. Mackall, wlio, it is alleged, was one of the partners of the firm of L. C. Leitch & Co.

At the trial, evidence was produced tending to prove that Leitch and the defendant were partners, constituting the firm, and also some evidence lending to prove that Richard G. Mackall was also a partner of the firm.

Upon this evidence the court, at the instance of the defendant, instructed the jury “that if, from the evidence, they believed that Richard G. Mackall was a member of the firm of Leonard C. Leitch ¿L Co., at the time of the execution of the note in this suit, then the jury should find for the defendant under the issue.”

*74(Decided March 26th, 1861.)

And the plaintiffs asked the following instruction: “That unless the jury shall find, from the evidence, that Richard G. ■Mackall was an actual partner of the firm of L. O. Leitch &• Go., at the time the note sued upon was executed, the plaintiffs are entitled to recover upon the present issue. [That evidence that the said Mackall was a secret or dormant partner of that firm at the time, is not sufficient to establish such actual partnership under the present issue.”]

The first part of this prayer was admitted by the defendant; but the court refused to grant the latter part, between brackets.

. In the opinion of this court, there was error in thus ruling. There was evidence in the cause,proper for the consideration of the jury, tending to prove that Mackall (if a partner of the firm) was only a secret or dormant partner, unknown to the plaintiffs; and if the jury so find, then, according to the authorities, the non-joinder of Mackall was no ground of abatement. See 2 Greenlf’s Ev., secs. 25, 134. Coll, on Part., sec. 719. De Mautort vs. Saunders, 20 Eng. C. L. Rep., 410. Mullett vs. Hook, 22 Eng. C. L. Rep., 259. Mitchell vs. Dall, 2 H. & G., 171, 172.

Many more authorities might be cited, establishing the proposition we have stated. The instruction given to the jury was, therefore, erroneous, and the plaintiffs were entitled to have the direction asked for by them given to the jury. The words “actual partner,” in this prayer, were obviously used as the opposite to secret or dormant partner; the usual and correct terms are ostensible or active partner; construing the prayer as if these words had been used, it properly states the law of the case, and ought to have been granted.

Judgment reversed and procedendo ordered.
