Tuhcrcular Disease of the Spine. 531 



The bodies from the third to tlie eighth vertebrae have been 

 ■■aflfected. The inter-vertebral foramina just at the bend have been 

 obliterated by the pressure of debris into them. The laminae 

 of the affected vertebrae are ossified together, and the fourth 

 and fifth spinous processes and laminae are greatly atrophied. 



The coincidence of the blocking of the inter- vertebral 

 foramina with the atrophy of the spinous process should be 

 noted in connection with No. 7. 238 ; but whether there is any 

 relation between them, as cause and efTect is uncertain.

There is an acute curvature in the lower dorsal region, and 

 the lower six vertebrae are fused into a common wedge-shaped 

 mass, with its apex projecting backwards. There are cavities in 

 its interior. The spinous processes at the angle are somewhat 

 atrophied, and thus the apparent acuteness of the curve is 

 diminished. B. C. i. 3. M. 10.

" This is a fine example of the curve, which is the consequence of 

 caries and anchylosis. Tlie oesophagus reached directly from the neck to 

 the diaphragm, so that it was not more than three inches in length, while 

 the aorta measured between the same points nearly nine inches." 



The bodies of the vertebrae from the seventh dorsal to the 

 second lumbar inclusive have been greatly absorbed, and their 

 remains fused into a common mass, in which the seventh 

 dorsal vertebra above touches the second lumbar below. The 

 spinous processes at the projecting angle are somewhat absorbed. 

 The upper portion of the dorsal spine has a compensating
