1382. The same; connected with caries of the first lumbar vertebra. A small opening upon each side of the spine; with extensive cicatrices, from former counter-irritation. 1847.
1383. Two lumbar vertebrae. The body of one is extensively destroyed by caries; and in its centre is a piece of dead bone far advanced in the process of separation. Some chronic arthritic growth, also, from the edges of the bodies. 1847. Dr. J. C. Warren.
1384. A lumbar vertebra, showing a large piece of bone in the process of separation from the under surface; caries not at all extensive. 1847. Dr. J. C. Warren.
1385. Three lumbar vertebras, showing deep caries of the bodies, but without loss of thickness. Edges of two of the bodies anchylosed by chronic arthritis. Laminae and processes not affected. 1847. Dr. J. C. Warren.
1386. One lumbar vertebra, similar to the last; the body being almost destroyed by caries, but without loss of thickness. 1847. Dr. J. C. Warren.
1387. Five lumbar vertebrae, and one dorsal; preserved in connection, and showing a caries upon one side. Quite a cavity in the fifth lumbar; though the disease is generally superficial. No curvature. Bones atrophied.
From a man, æt. twenty-eight years, who died in the hospital (50, 160). Disease of nearly one year's duration, and began with severe pain in the abdomen. A large abscess formed in the groin, early in the disease, through which, toward the last, the urine passed; and a second, near the back part of the crest of the ilium. On dissection, this last was found denuded; and there was a large abscess
