The defendant was tried for murder, found guilty without capital punislnnont, and sentenced to imprisonment in the State Penitentiary for life. Prom this judgment he has appealed.
It appears by a bill of exceptions that the defendant placed on the stand certain witnesses, and asked each of them seriatim, “to state the acts, declarations and conversations and exclamations, they saw, had with and heard the prisoner make, at any time shortly before, at the-time of, or after the killing of Sinnott, tending to show the condition of his mind; which question and answer was objected to by the Attorney General for the State, on the grounds that his (the prisoner’s) statements, declarations and conversations- were inadmissible, and were illegal. The court sustained the objection to the question and answer, in so far as to limit the same to the acts and the exclamations of the prisoner a short time previous to and at the time of the killing2, and to the acts after the occurrence.”
In signing the bill, the judge adds, “Every conversation for two osthree months previous to the homicide, accompanying any act indicating unusual excitement, was admitted; other conversations were excluded.”
The defense in this case was insanity. In the solution of the question presented by this bill of excex>tions, it becomes necessary, therefore, to inquire what scope is allowed to'the prisoner in establishing such a defense by the enlightened spirit of modern jurisprudence.
Insanity is a disease. It has its pathology and its symptoms, and it would seem that its existence can be determined only by a careful scrutiny of those symptoms. The tree is to be known by its fruits : the condition of the hidden mechanism is to be ascertained by those communicated movements which are external and ax>x>arent. To this end the usual expressions of a mental state are original and competent evidence. If they are the natural language of mental alienation, they furnish satisfactory, and sometimes the only proof of its existence. It is true, that such expressions may be feigned, and often are; but whether they were real or feigned is for-the jury to determine. Hence, the rule prevails that as indicia of the mental condition, not only the acts, but the conversations, exclamations and declarations of the person may be shown. Of course, this rule should not be extended beyond the necessity on which it is founded — mere narration or statement by the accused, as that at a certain time he said or did something, or that at a certain time he was insane, must be excluded; but testimony of such dex>ortment, action, comx>laints, exclamations, declarations and expressions, as usually and naturally accompany and furnish proof of an existing-malady, ought to be freely admitted.
We think it equally well settled that all such indicia occurring after the commission of the offense, may be shown, and that the judge, therefore, erred in confining the testimony to acts done after the homi*41cide. It is true, that, mania is often simulated, and it is quite likely that the danger of simulation may increase after the commission of a. homicide; but this consideration relates rather to the effect of the testimony than to its admissibility. It may have little weight; but such as it has, the jury must estimate. Previous or subsequent insanity in itself is no matter of excuse; the mania must have existed at the time the act was done; yet, evidence of the presence of the malady, either before or after the- act, is proper to be weighed by the jury, for the purpose of forming a conclusion whether insanity existed at the time the alleged crime was committed. And this evidence, we apprehend, may be identical in character with that which is admitted to establish mental unsoundness prior to the act.

For the' reasons given, it is ordered that the judgment appealed from be avoided, and the verdict of the jury set asido, and that the cause be remanded for a new trial, according to law.
