524 Diseases of Joints. 



The bodies of tlie last cervical and first six dorsal verte- 

 brae have been destroyed, and have disappeared. The spine 

 has thus been so bent upon itself that the head of the first rib 

 is close to that of the sixth, and the bodies of the sixth cervical 

 and sixth dorsal vertebrae nearly touch. The spine of the 

 third dorsal vertebra is greatly atrophied, and there is a distinct 

 space between its laminae and those of the vertebrae above 

 and below it. Some of the articular processes seem to be 

 anchylosed. This must have been a case of paraplegia, and 

 probably also of abscess. G. C. 596. a.

Bodies- — Portion of a dorsal and lumbar spine — in spirit, 

 showing extensive destruction of the bodies of two of the 

 lower dorsal vertebrte. 



Some of the di'bris of the affected vertebrae seems to have 

 been crushed backwards upon the spinal cord, and no doubt 

 compressed it. The bodies of the adjacent vertebrae have been 

 eroded on the surface, and opaque patches of caseation can be 

 seen here and there in their interior, although there has not 

 been much alteration of their general shape. Part of the wall 

 of an abscess cavity is shown attached to the sides of all the 

 bodies in the preparation. It seems to have opened backwards 

 past the transverse processes, as well as communicated with the 

 canal at the place where the bodies have disappeared.

— Parapleg'ia. — Lower cervical and dorsal spine, apparently 

 of a young person — in spirit, showing great destruction of the 

 bodies in the mid-dorsal region.
