“CASE 2.—A woman, aged forty-six years, suffering from cardiac disease, hemiplegia, and dementia, took fifteen grains of chloral, three times a day, with calming effect. On the nineteenth day of the treatment numerous purple-red spots appeared in the neighborhood of the left elbow; on the next day many similar spots were seen on the shoulders and forearms, which coalesced with the others. On the twenty-first day livid spots came on the face; the left arm swelled and became hard. On its surface appeared a multitude of minute points, of a much deeper color, which did not diminish on pressure. Next day there were dark purple spots and discolorations; some small, round, and circumscribed; others broad and irregularly shaped, on the legs and abdomen, and in stripes on either side of the vertebral column. Simultaneously with the petechia there was great prostration, tendency to somnolence, weakness and excitability of the pulse, sore lips, thickly coated tongue. On the twenty-third day the spots and discolored patches had extended in every direction, and the previously bright-red spots had assumed a deep-purple color. Finally, signs of lung congestion appeared, with gradual failure of power, and death, after several fainting fits, on the twenty-sixth day. At the autopsy numerous ecchymoses, of every shape and size, were observed, more or less, on all parts of the skin; the right lung was congested and œdematous; the heart dilated and its valves thickened; over the right central hemisphere there was a large arachnoid cyst, containing fluid blood. “With the foregoing may be joined a case, related by Monkton, in which, after four days’ administration of sixty grains of chloral daily, a rash resembling slight variola, with hemorrhagic purpura, appeared, and death occurred on the sixth day, by syncope. “Finally, may be mentioned two patients of Pelman, in whom, after treatment with chloral, there were larger and smaller petechia over the whole skin; in one which proved fatal numerous petechia were found on the mucous membrane of the larynx and under the endocardium, and a hæmatoma on the right side in the skull, reaching to the base, the fluid contents of which gave evidence of their recent origin.
