“ To punish an individual utterly unconscious of the difference between right and wrong at the time of committing the alleged crime, shocks one's sense of natural justice, and confounds all the principles on which it can be administered by man. How can we hang a maniac who, in a paroxysm of madness, kills the keeper who was endeavouring to soothe or to restrain him? Or one who shoots another whom, under the veritable and sole influence of delusion, he believed to be in the act of killing him, and that he was therefore acting solely in self-defence? ”
