there oozed from many points a quantity of dark blood, indeed the whole head was loaded with venous blood. The lateral ventricles were considerably enlarged and filled with water--four ounces were collected. The internal carotid arteries were much enlarged, and when divided, did not collapse, but remained open, as arteries in the other parts of the body. The consistence of the brain was doughy. CHAP. IV. CASES OF INSANE CHILDREN. In the month of March, 1799, a female child, three years and a quarter old, was brought to the hospital for medical advice. She was in good bodily health, and born of sane and undiseased parents. The mother, who attended, stated that her husband's parents and her own had never been in the slightest degree afflicted with mania, but that she had a brother who was born an ideot. She related that her child, until the age of two years and a half, was perfectly well, of ordinary vivacity, and of promising talents; when she was inoculated for the small pox. Severe convulsions ushered in the disease, and a delirium continued during its course. The eruption was of the mild kind, and the child was not marked with the pustules. From the termination of the small-pox to the above date, (nine months) the child continued in an insane state. Previously to the small-pox, she could articulate many words, and use them correctly for the things they signified: but since that time she completely forgot her former acquisitions, nor ever attempted to imitate a significant sound. Whatever she wished to perform, she effected with promptitude and facility. She appeared anxious to possess every thing she saw, and cried if she experienced any disappointment; and on these occasions she would bite, or express her anger by kicking or striking. Her appetite was voracious, and she would devour any thing that was given to her, without discrimination; as fat, raw animal food, or tainted meat. To rake out the fire with her fingers was a favourite amusement, nor was she deterred from having frequently burned them. She passed her urine and faeces in any place without restraint; but she could retain a considerable quantity of the former before she discharged it. Some cathartic remedies were ordered for her, with an emetic occasionally, and she was brought to the hospital every fortnight, but she did not appear in any degree amended. On June 22 she was admitted a patient, and continued in the hospital until the middle of October, when she was attacked with an eruptive fever, and consequently discharged. During this time little progress was made, although considerable pains were bestowed. She became more cunning, and her taste appeared improved. The cathartic medicine, which she drank at first without reluctance, became afterwards highly disgusting, and when she saw the basket which contained it, she endeavoured to escape and hide herself. To particular persons she was friendly, and felt an aversion to others.
