The mouth presented a horrible appearance. No sign of the teeth could be discovered, though it was stated that several had appeared. All that could be seen was a purple mass, which was so extensive that on superficial inspection it was difficult to distinguish between the upper and lower jaws, despite their wide separation. Scattered over this purple mass were areas of necrosing tissue, the odor of which was extremely unpleasant. Petechial hemorrhages were distributed over the back and limbs, and a large patch of extravasated blood was found in the region of the left hip. Tenderness was present in all the limbs, as manifested by moaning and by the facial expression. There was a general enlargement over both humeri throughout their length; the ulna and radius did not appear to be thus affected, but the index-finger of the right hand was enlarged, especially at the junction of the metacarpal bone with the first phalanx, the enlargement being at each side of the joint. In the legs the signs were extreme. At both knee-joints the skin was tightly stretched over the swollen epiphyses; the tenderness also was greater than at any other part. Bleeding from the gums and nose had occurred; no history of hæmaturia could be obtained. The motions were semisolid, green, and offensive. During the last twenty-four hours the infant had refused food. The baby was given large amounts of lemon juice and subcutaneous injections of salt solution and the necrosing surfaces of the gums were scraped and swabbed with boracic solution. By the third day the pulse was 100, the temperature 99.8°, the odor from the mouth scarcely noticeable, and the general condition distinctly improved. It continued to improve and to gain in weight and when seen at the end of the sixth week of treatment it was doing well and was quite happy. It will be well to consider in detail the signs and symptoms which may develop in the course of scurvy.
