The patient, get. nineteen, entered the hospital (125, 32) Nov. 8th, 1865. Four years before he was shot in the knee, and for the next year kept his bed, with much swell- ing and profuse suppuration. No motion in joint for three years, though there was but little pain. The knee was bent to an acute angle ; the leg was much atrophied, and the bone could be felt through an old sinus. Amputation on the llth. On the 21st the bone protruded ; much pain followed ; and on the 29th of Dec., 5 in. of the femur were removed. To the extent of about 4 in. it was sur- rounded by new bone from to f in. in thickness ; and on section, in the recent state, it showed finely the appear- ances of osteo-n^elitis. (See Nos. 1280-1).

1444. Upper half of the astragalus, from a woman about forty- five years of age, " and of a decidedly scrofulous diathesis."
