Opinion by
Mr. Justice Walling,On March 22, 1920, the wife of defendant, Floyd Smith, gave birth to a male child, called Francis Smith. They were then residing at Elmira, New York, and, as they had been married but two months, defendant denied the paternity of the child. On April 20, 1920, its dead body was found partly covered by rocks in the bed of a creek, near South Waverly in Bradford County, Pa. At the trial defendant admitted placing the child’s body in the creek and that he had caused its death, but claimed the latter was accidental. He was convicted of murder of the first degree and, from the sentence pronounced thereon, brought this appeal.
We have carefully examined the entire record but find no cause for reversal. There was evidence that defendant had been unkind to the child, had tried to give it away and had threatened its life. In that connection the district attorney stated in opening the case, “that the child was so treated that the officers of the Society for the Prevention of Cruelty to Children were called in.” Defendant’s counsel objected to this statement and unsuccessfully requested the withdrawal of a juror. When proof of such statement was offered it was excluded, but the trial judge finds the district attorney acted in good faith. It is not necessary to decide whether the proof offered was competent, for a conviction will not be set aside because in outlining his case in good faith the dis*586trict attorney accidentally refers to some matter as to •which the trial judge later excludes evidence (see Commonwealth v. Henderson, 242 Pa. 372), otherwise every offer of incompetent testimony made in the presence of the jury on part of the Commonwealth might cause a mistrial.
Defendant was arrested April 22, 1920, in Binghamton, New York, and thereupon made a written statement of an incriminating nature. This was properly admitted in evidence as it was shown by the Commonwealth to have been voluntarily made, without coercion or promise.
While in jail, awaiting trial, defendant wrote a letter to his wife, who was also confined in another part of the jail on the same charge, which contains damaging statements. Defendant handed the letter, unsealed, to a fellow prisoner with a request to deliver it to the wife, which was not done. The trial judge properly admitted the letter as evidence for the Commonwealth; it never came to the wife’s possession and therefore was not a piece of evidence furnished by her directly or indirectly. In this the case differs from Com. v. Fisher, 221 Pa. 539. As the open letter was handed to a third party and never reached the wife, it cannot be regarded as a confidential communication between husband and wife: Hammons v. State (Kan.), 68 L. R. A. 234; People v. Dunnigan, 163 Mich. 349, s. c. 31 L. R. A. (N. S.)940. It is not unlike the case of statements made by a husband to his wife in presence of a third party, and to which the latter may testify: 5 Chamberlayne on the Modern Law of Evidence, sec. 3699, p. 5294.
Captain Shay, of the Binghamton police department, was present and talked with defendant when hie made the written statement, and we see nothing prejudicial in permitting the captain to testify that later when he sought further conversation with defendant, the latter said he refused to talk on advice of counsel. That was a proper attitude for a defendant to take and did no harm. Nor was it improper to permit the district attor*587ney to ask the defendant upon cross-examination who his counsel then was.
The latitude of cross-examination is largely in the discretion of the trial judge; and there was no such abuse thereof as calls for a reversal in permitting the district attorney to ask defendant what he meant by certain expressions in the letter to his wife, as it was in evidence, and greater latitude is permissible in the cross-examination of parties than of other witnesses. In other words, when a letter, written by a party to the suit, is in evidence, it is not reversible error to permit him to be asked on cross-examination what he meant by certain doubtful expressions therein.
What is excusable conduct in a prosecuting attorney depends somewhat upon the surroundings and atmosphere of the trial. Here defendant had just testified that before he made the statement at Binghamton the district attorney had taken him aside and practically promised him and his wife immunity if he would “tell the truth.” It was then the district attorney asked, “Don’t you know that is a miserable frame-up in your mind?” The question was improper and the trial judge promptly sustained an objection to it, but it was not such glaring misconduct, under the circumstances, as required the withdrawal of a juror. It was natural for the district attorney to resent the charge of grave misconduct made against him, and to take the witness stand, as he did, and deny it. Had he failed to do so, it would have been a tacit admission that he promised the defendant immunity to secure a confession; hence, it would be unjust to apply here the unwritten rule that precludes a lawyer from being a witness for his client.
The defendant and his wife left Elmira with this child on the afternoon of April 16, 1920, and arrived in Waverly about dark, where they left the train, and, as he states, walked south into Pennsylvania intending to leave the infant on the porch of some farm house. They came to an earth road, it began to rain and he testifies *588that the wife went back to the railroad waiting station, while he went on with the child, and further that as he approached a farm house he was set upon by a dog and, in running away, stumbled in the road and fell upon the babe causing its death, and then being frightened placed it in the creek, with the stones upon it, as above stated. This story disagrees with his Binghamton statement wherein he says the child Avas alive and crying when he left it in the creek. It disagrees with one statement he made that they had given the child to a young married couple and with another statement that they had given it to a woman named Myrtle. An autopsy disclosed that the infant’s head had been crushed on both sides, as if placed on a large rock and then violently struck with a smaller one; and further that it was dead when placed in the creek. Defendant took with him that night a bundle of the child’s clothes, which was found next day on a near-by freight car with no mud or dirt upon it. This discredits the alleged fall with the babe and bundle in the wet dirt road. Moreover, it would be next to a physical impossibility for a man to fall forward, as he says he did, in a dirt road, while carrying an infant, so as to fracture both sides of its flexible skull. All the evidence points to the conclusion of a wilful killing under such circumstances as seem to excuse the district attorney’s remark to the jury that Under the evidence its perpetrator “didn’t have the heart of a man, or the soul of a man.” At least such remark under the facts did not demand a discharge of the jury and a continuance of the case. Complaint is also made that the district attorney said to the jury, “Don’t you suppose he told the attorney about the whole matter?” As the context is not stated, it is impossible to know to whom or what the question referred or whether it was improper.
As the verdict of the jury implies a finding that the killing was wilful and intentional, the defendant was not harmed by the district attorney’s remark to the effect that involuntary manslaughter was a minor offense.
*589The charge of the trial judge was fair and adequate and the criticisms made to excerpts therefrom are entirely without merit.
The assignments of error are all overruled; the judgment is affirmed and the record is ordered remitted for the purpose of execution.
