answers, although she never began a conversation. During the day she sat apparently sullen and abstracted, and seemed to take no notice of what was passing. After the elapse of three weeks, as she was sitting in her usual manner, she uttered a shriek, appeared for a few moments in a state of alarm and confusion, and suddenly recovered.—Of her repeated attempts at suicide she had not the slightest recollection.—When I visited her the following day she received me as a perfect stranger; and was not conscious she had ever seen me before; and during several subsequent interviews, in order to be certain of her recovery, I was persuaded she did not retain the slightest remembrance of any of the circumstances of her malady. A third case of this nature lately occurred. A young man with hereditary predisposition to insanity, his mother and grandmother having been so disordered; in consequence of severe losses, was seized with a paroxysm of furious madness, which continued without abatement for four months. At the expiration of three months he had a considerable mortification on the lower part of the back, which required surgical attention during three weeks. When the sore was healed he was removed to another situation for the treatment of his insanity, where he perfectly recovered. After his complete restoration he neither recollected the asylum where he was first placed, the disease of his back, nor his removal to the situation where he ultimately regained his reason. To the states of mind above described, the question of good and evil can in no way apply; because these persons have wanted all recollection of their state, and of any act perpetrated; which implies that they were unconscious of any motive urging them to its commission; and which being unremembered, renders them incapable, as moral agents, of contemplating the RIGHT or WRONG of the act previous to its execution. It is likewise well known, that even ideots, who are ordinarily tranquil, and apparently harmless, will occasionally burst into paroxysms of fury, and deal indiscriminate destruction to those around them, frequently without the slightest cause, and certainly without pre-meditation:—and whose inferior scale of intellect does not enable them to give a reason for their actions. These states have been mentioned that they may be recognized by the medical practitioner, and become known to the advocate, in order that he may apply them to the existing law.
