Her intellect did not begin to weaken until two years since, but she ceased growing and learning after the first attack. At this time she does not know her right hand from her left; does not know her mother, and shows no signs whatever of ordinary intelligence. From being cleanly as a child, is now most filthy—in fact, is in every sense an idiot. Has never menstruated. _On examination_—although, as stated by Dr. Marley, the mammæ were very rudimentary—there was full development, and indeed abnormal hypertrophy, of the external genitals. Feb. 18. The usual operation performed, under chloroform. The hands to be restrained, and the patient most carefully watched. Feb. 19. Has passed a good night, and is quiet. Feb. 23. Has been very drowsy since the operation. To-day asked for food for the first time, and showed some signs of intelligence. Feb. 26. Gave rational answers to several questions which were asked her. Also remembers from day to day any promises of delicacies of diet or money. March 1. Passed a good night; feels free from pain. Was given some printed cards, which she read—_the first time for nine years_. March 2. Improving much. Is much more modest in her behaviour, but still passes her excretions without regard to time or place. Notices passing events, and remembers names and faces. March 3. Has given sensible and somewhat witty replies to various questions asked her in the presence of about twenty medical gentlemen, who to-day came to see the operation. When moneys were given her, she at once told their different relative value. March 4. Morning: Seems no worse for the excitement of yesterday.—Evening: Had a slight fit. March 5. A little heavy and stupid to-day. Somewhat irritable and obstinate. March 6. Much better. Has a daily clearer notion of right and wrong. Likes books with pictures and large print. When she comes to hard words, she asks the meaning, like a child, but cannot always grasp the meaning of an explanation. March 8. Not quite so well to-day. Had a slight epileptic fit this evening, followed by a very severe one in two hours. March 9. Again much better, but irritable. March 12. Two fits. March 16. Not so well: another fit to-day. She from this time seemed to retrograde; and on the 4th of April was discharged as incurable.
