When I was at the Kingston Asylum, Ontario, last August, a male patient had just escaped from the institution, and made a criminal assault upon a little girl in the neighbourhood. From the inquiries I made, I found that the case was one of much interest in its bearing on moral insanity (or imbecility), and I was allowed to read the notes in the well-kept case-book of the asylum. Dr. Metcalf, the medical superintendent, has very kindly permitted me to make use of them, and the farther particulars of this patient's history and acts, which he has given me. A photograph was subsequently taken, which I have had reproduced by the London Autotype Company. (See Plate.).
