7. 212. Lateral Curvature, with Anchylosis.— Cervical and 



dorsal vertebrfe, with the ribs attached — macerated, illustrat- 

 ing the above. 



The patient died of consumption. 



The spine, as a whole, is bent forward. There is a lateral 

 curve to the left, in the upper dorsal region, having its maxi- 

 mum about the fourth dorsal vertebra ; and one slightly to the 

 right in the lower dorsal region. The upper ribs on the left or 

 convex side are raised and opened out, the angles projecting 

 backwards, while those on the concave or right side are com- 

 pressed, and the angles flattened. The bodies of the fifth, sixth, 

 seventh and eighth dorsal vertebrse are fused together, and some 

 anchylosis has occurred between the eighth, ninth, and tenth 

 dorsal vertebrse. B. C. i. 3. M. 20. 



7. 213. Old-Standing" Lateral Curvature. — Last cervical, 

 dorsal, and two upper lumbar vertebra, with the ribs attached — 

 partially dissected and dried, showing alternating lateral curves. 

 A curve to the left in the upper dorsal region has its 

 maximum about the third vertebra, and one to the right in the 

 lower dorsal region has its maximum about the tenth vertebra. 

 Apparently there has been another curve to the left in the 

 lumbar region. There is a slight rotation of the vertebrae 

 towards the convexity, with corresponding changes in the ribs, 

 as noted in the previous specimens. The first rib is not as 

 much elevated as might have been expected. This may 

 have been due to faulty mounting. B. C. 1. 3. M. 15. 



7. 214. Advanced Lateral Curvature. — Cervical, dorsal, and 

 lumbar regions of a spine, with portions of ribs attached — 

 macerated, illustrating the above. 



From an adult who died of disease of the lungs. 



There is an alternating series of lateral curves. The 

 principal curve is in the lower dorsal region. Its convexity
