Smith v. United States
Pages 4

It is conceded that defendant committed the crime charged. No good purpose, therefore, would be subserved in reciting the horrible circumstances attending the conception and perpetration of the crime. A single question of law is presented for our consideration. The solo defense interposed on behalf of the defendant was insanity, and counsel for defendant requested the court to submit to the jury the following prayer: "The jury are instructed that if they believe from the evidence that at the time of committing the acts charged in the indictment the defendant was suffering from such a perverted and deranged condition of his mental faculties as rendered him incapable of distinguishing between right and wrong, or unconscious at such time of the nature of the act charged in the indictment while committing the same, or where though conscious of them and able to distinguish between right and wrong, and to know the acts were wrong, yet his will, the governing power of his mind, was, otherwise than voluntarily, so completely destroyed that his action was not subject to it but beyond his control, it will be their duty to acquit the defendant, and in such case their verdict shall be not guilty."
