Opinion by
Mr. Chief Justice Fell,On a trial for murder the question of degree is always for the jury. It goes to them with the question of guilt and an instruction that withdraws it is erroneous: Commonwealth v. Sheets, 197 Pa. 69; Commonwealth v. Kovovic, 209 Pa. 465; Commonwealth v. Frucci, 216 Pa. 84. In the case last cited a reversal was had because of the instruction in the charge, “You will have to do in this case with the kind of murder stated in the statute as wilful, deliberate and premeditated murder” and in the answer to the request of the jury to again define to them murder of the first degree, murder of the second degree and manslaughter, “It is the wilful, deliberate and premeditated killing that you are to deal with in this case.” These expressions were held to be equivalent to an instruction that the crime committed was murder of the first degree and to take from the jury the right to fix the degree. In the case at bar the instruction complained of was, “The crime with which you have to do in this case, under the testimony and according to the theory of the Commonwealth, is the kind known as a wilful, deliberate and premeditated killing.” It is argued that this instruction under the ruling in Commonwealth v. Frucci, supra, entitled the appellant to a reversal. This expression standing alone is not free from criticism, but considered in the connection in which it was used it is not open to the objection urged *599against it. It was followed by the statement, “It is therefore necessary that you should have a distinct understanding as to what is meant by ‘wilful, deliberate and premeditated killing’ ” and by clear instructions on the subject and the jury were repeatedly told that it was their duty to fix the degree. Considering the whole charge the jury must have understood that it was the Commonwealth’s theory based on its testimony to which the court referred.
We have reviewed the testimony in the case as required by the Act of February 15, 1870, P. L. 15, “to determine whether the ingredients necessary to constitute murder of the first degree shall have been proved to exist.” This review is limited to the inquiry whether competent evidence to sustain a conviction was presented by the Commonwealth: Grant v. Commonwealth, 71 Pa. 495; Commonwealth v. Garrito, 222 Pa. 304; Commonwealth v. DeMasi, 234 Pa. 570. We find that, it was and that under the Commonwealth’s testimony the murder was wilful, deliberate and premeditated. With this our duty ends; the credibility of the witnesses was for the jury. The remaining assignments of error call for no discussion; a number of them are not based on exceptions, and those that are are without merit.
The judgment is affirmed and the record is remitted for the purpose of execution.
