My paper to-day is the natural outcome of the address by Sir William Gowers upon “Sanity and Insanity, Lunacy and Law, the Views of a London Hospital Physician, particularly in regard to Private Patients,” given at our last general meeting in London. The discussion which followed was hardly worthy of the subject. Most of the earlier speakers, although eminent general physicians, had had little or no experience in the care and treatment of the insane; therefore, when the turn came for those practically acquainted with mental diseases to speak, the hour was advanced, the audience was weary, and an all too exacting brevity resulted.
