■ “ One ground of the defense asserted was the insanity of the prisoner. After it had been shown that he was subject to fits of epilepsy, and to what were claimed to have been delusions ; that his mother died of paralysis and softening of the brain; that he occasionally talked in a manner which the witnesses deemed irrational; and that his mother had epileptic fits during her life-time, and her death was described in the certificate of the health department as in consequence of the ■disease of pachy meningitis; after this general proof Dr. O’Brien was called by the defense as an expert. After several efforts to frame a suitable question the doctor was permitted to answer that any man whose mother died of pachy meningitis would be predisposed to insanity. Such predisposition having been shown, the attention of the expert was drawn to ■the prisoner’s actual mental condition, and a series of hypothetical questions were framed, to some of which objections by the prosecution were sustained. The ruling of the court in these instances was based upon the doctrine that the hypothesis submitted for an opinion must be based upon the proofs, and must not go outside of the facts as to which some evidence had been given, and which, therefore, could be assumed as the possible truth. If the trial judge at one stage of the case expressed this doctrine somewhat more vigorously, he made no ruling which went beyond it. (People v. McElvaine, 121 N. Y. 250.) The first question assumed that the symptoms of the prisoner’s fits indirectly proved that they were epileptic, and wholly omitted the other facts relied on. The court complained-that the opinion of the expert was being asked 1 piecemeal,’ and the prisoner’s counsel tried again. The second attempt included an injury to the skull, of which it was conceded that there had been no proof. The third attempt was not •objected to, and the expert answered that the facts indicated ■epilepsy, and thati in epilepsy, of course, a person might at •any moment become insane.’ Very naturally the prisoner’s •counsel was not satisfied with this answer, and for the fourth time framed a hypothetical question, but in doing so assumed as a fact proved which had not been sworn to by anyone that ithe fits and fainting spells < indicated disease of the brain.’
“Along this line of inquiry a specific question was asked and excluded. It was this: £ Suppose that a man commits a crime, and that when arrested for the crime, from his language, he had forgotten all about the crime if he had committed it % ’ The court asked for the evidence tending to support the hypothesis, and it turned out to be that when arrested he asked what he was arrested for. The inquiry did not indicate forgetfulness of what had occurred, and no rational argument to that purpose could be founded upon it. The prisoner ran away after the shooting: he did not know whether his victim
