The defendant was convicted of the crime of using certain instruments upon the body of Wanda Szidzewicz with intent to procure her miscarriage, in consequence whereof she died. The Commonwealth offered in evidence a statement of the deceased as a dying declaration. The presiding judge, in the absence of the jury, heard evidence which justified him in admitting the declaration. He then told the jury, in substance, that he had found the statement to be a dying declaration and relevant and material to the issue, but that it was for them to determine whether it was a dying declaration within the law as he would explain the matter to them, and that unless they so found, they were not to consider it in any way; but if they did find that it was a dying declaration, they were to give it such weight as they thought it entitled to. The defendant excepted to this instruction, objecting more specifically to the part in which the judge said that the statement was a dying declaration. The statute prohibiting the court from charging in respect to matters of fact applies to the charge only. G. L. c. 231, § 81. During the rest of the trial the court has the same right concerning matters of fact that existed before the statute was adopted. Partelow v. Newton & Boston Street Railway, 196 Mass. 24. But the statement was not objectionable whether made during the trial or in the charge. Where the law requires a judge to make a preliminary finding of facts it is proper for him to state his finding to the jury. Commonwealth, v. Brown, 14 Gray, 419. Commonwealth v. Robinson, 146 Mass. 571. Commonwealth v. Brewer, 164 Mass. 577. Commonwealth v. Bishop, 165 Mass. 148. Commonwealth v. Rogers, 181 Mass. 184. In the charge, full and accurate instructions as to the admissibility of such declarations were given to which no exception was taken, and the final responsibility of deciding the questions relating thereto was placed upon the jury. No prejudicial error appears in connection with this exception.
The defendant offered to prove that when arrested she asked the arresting officer what she was arrested for and then told him that she was innocent of the alleged crime. The ruling of the trial judge excluding this testimony was right. *513The statement if made was merely self-serving. The statute giving an accused person the right to know from the officer the grounds on which the arrest is made, does not make her conversation with him competent at her trial. G. L. c. 263, §1.
No reversible error is disclosed by the record in connection with the use, by the witness Stapleton, of a memorandum to refresh his recollection. The only ground of objection alleged is that the witness was reading the memorandum instead of refreshing his memory from it. But the record shows that he was making a proper use of it under the direction of the court.
The defendant contends that a medical witness was improperly permitted to give an opinion as to the intent with which the instruments introduced into the body of the deceased were used. But this is not the import of the questions asked. The witness was the medical examiner who had performed an autopsy on the body of the deceased and found no evidence of violence outside or in. He had also testified to a statement made by her to the effect that the defendant had used instruments to procure her miscarriage. He was then permitted to answer, in reply to a question by the assistant district attorney, that the conditions which he found at the autopsy were consistent with the use of instruments with intent to procure an abortion. The Commonwealth was within its rights in asking the question. It did not call for any opinion as to the intent with which the act was done, nor even for an opinion whether instruments were used or an abortion performed. Evidence tending to show that there was nothing in the conditions disclosed at the autopsy inconsistent with the theory of the case based upon the other testimony offered by the Commonwealth was competent. Unless such a question were asked the jury might draw an inference from the doctor’s testimony that instruments to procure an abortion could not have been used.
The doctor who produced the hospital records testified at length in cross-examination as to the frequency and causes of accidental abortion; and stated that the condition which he found at the autopsy was consistent with an accidental abor*514tian; that if the patient lifted a heavy box of wood while pregnant she could have an abortion and that such a cause would be consistent with the condition found in the woman. It appears from the hospital records that she had lifted such a box four days before. Thereafter in cross-examination of a medical witness, the defendant’s counsel asked the question, whether one could have an abortion from the constant jarring operation of a sewing-machine; and on being asked, by the trial judge, whether he contended that it happened in that way and whether such evidence would be introduced, replied: “The woman said so herself. I think I have a right to examine the doctor about his knowledge.” The judge excluded the question subject to the defendant’s exception, stating that they did not need to go into questions on which there was no evidence. When the defendant later began to inquire further of the same witness about accidental abortions, the judge said, “Haven’t you been over the question?” and counsel said that it was new; that he had not been over this phase, and then started to ask another question about accidental abortions. The judge then ruled, subject to defendant’s exception, that counsel could not inquire further of that witness about accidental abortions. It did not appear from any offer of proof that material evidence was expected to be elicited by replies to the questions asked. There was no testimony offered in the case or that tends to show any trouble which might be connected with the use of a sewing-machine. When we consider the extent to which counsel was permitted to cross-examine a doctor called by the Commonwealth in regard to accidental abortions and their causes, and the uncontroverted testimony that the condition found at the autopsy was consistent with an accidental abortion, it cannot be said that the judge abused his discretion in refusing to permit counsel to inquire further as to such abortions. In so far as the inquiries were made to test the knowledge of the witness the matter was largely in the discretion of the judge and upon this record the ruling must stand.
The defendant having testified without objection, so far as the record discloses, that she had not assisted in the de*515livery of a child on Wright Street and had never told Dr. Stapleton or any one else otherwise, and that no one had ever said in her presence that she, Mrs. Cantor, had made such delivery, the trial judge permitted the Commonwealth to offer evidence that the defendant’s husband in the defendant’s presence stated to Dr. Stapleton that she had delivered this woman on Wright Street of a child and that the defendant said nothing. In these circumstances it was for the jury to say whether the defendant by her silence assented to the statement made by her husband. The testimony was competent to contradict that of the defendant. Foster v. Worthing, 146 Mass. 607, 608. It is assumed that the defendant’s acts on Wright Street were material, as they might well be, to show the defendant’s knowledge of such matters.
One of the defences was that at the time of the alleged abortion the defendant was attending a birthday party of her grandchild in New York. In support of this claim her counsel asked a witness, showing him a paper, if that was a certificate of the child’s birth. This was excluded subject to the defendant’s exception. The question related to a collateral matter and it did not appear that the paper was a proper record to be admissible in evidence, or that the witness was competent to answer the question asked.
A court stenographer was called for the purpose of contradicting Dr. Sawyer, who had testified for the Commonwealth that he had told the deceased that she could not live. The evidence offered was to the effect that Dr. Sawyer had said that he did not know whether the deceased thought she was going to die. This was properly excluded for the reason that it did not contradict the doctor’s testimony.
All exceptions argued have been considered and no reversible error is disclosed by the record.
Exceptions overruled.
