As an excuse for the commission of an act otherwise criminal, this term means an impulse towards its commission of such fixity and intensity that it cannot be resisted by the person subject to it, in the enfeebled condition of his will and moral sense re-sulting from derangement or mania. See INSANITY. And see State v. O’Neil, 51 Kan. 651, 33 Pac. 287, 24 L. R. A. 555.
