the junction of the second and third phalanx to the point of juncture of the ulna with 

 the radius at the wrist. The knife passed readily through the os magnum, the semi- 

 lunar bone, and the outer articular edge of the radius. The distal end of the os magnum 

 was found to be completely disintegrated, and between it and the upper end of the second 

 metacarpal bone was lodged a mass of dark-brown substance, the brown tint predominating 

 towards the centre, where, it might almost be described as presenting a dark-red tint. 

 Several other aggregations of dark material were found lying between this mass and 

 the flexor tendons. 



In the subcutaneous tissue along the back of the radius, there were several isolated 

 little cavities, or cysts, containing aggregations of a cheesy, fatty substance mixed 

 with black granules. They could be picked out separately for examination ; in the 

 dark masses filaments could be distinguished after prolonged immersion in potash ; but 

 in the yellowish, roe-like particles, picked out of the same cavities and similarly treated.

no such filaments could be demonstrated when the particles were carefully selected. 

 These isolated cavities were limited to the subcutaneous areolar tissue between the 

 extensor tendons and the skin of the back of the wrist. 



Specimen IV. — Another hand, also amputated a short distance above the wrist joint. 

 The hand was considerably thickened and the wrist swollen : the palmar surface was 

 puffed up, and numerous openings both there, on the dorsal surface, and between the 

 fingers, communicated with a large cavity within. A scalpel was carried longitudinally 

 through the middle of the hand, the bones that still remained being readily divided, 

 as well as the end of the radius for a short distance. All the carpal together with a 

 great part of the metacarpal bones were destroyed, — the basal half being the portions 

 in the latter most affected. The phalanges were somewhat softened, but were not 

 eroded, and contained no black matter. The metacarpal bone of the third finger was 

 eaten out and rough, the destruction having proceeded so far as to separate the bone 

 into two rough, irregular fragments. There was not much thickening on the uneroded 

 surfaces. The cavities in the bones were not lined, and the bone presented the appear-
