quisite to set forth in the plea, the record of the former acquittal,” &c. 1 Chit. Crim. Law, 459. The pleas in this case, conform to this simple rule of pleading, but go one step further and show, that the verdict relied on as an acquittal of the plaintiff in error, was set aside, and that a new trial was ordered. The Solicitor General demurred to the pleas, and the Court below sustained the demurrer. If the defendant rely upon the record, as he must, for his acquittal, .he must plead and prove a subsisting record of acquittal. It is no record if set aside. But it is argued, that the acquittal of the offence of murder, remains, although the verdict of guilty of manslaughter is set aside. The verdict of guilty of manslaughter is only an implied acquittal of the accused of the charge of murder, and if the verdict from which the inference is drawn, is set aside, nothing is left to sustain the inference.

If a party be accused of a high offence, and on an indictment therefor, he is convicted of one of inferior grade, he must be' careful, how he removes the only barrier to a second trial. The State can in no case move for a new trial on the acquittal of a person indicted. Our statute declares that in criminal cases, the jury shall be judges of the law and the facts, and the Legislature has effectually guarded this prerogative of the jury against invasion by the Courts to the prejudice of a person indicted, by enacting that on the acquittal of any defendant or prisoner, no new trial shall on any account be
