Lateral Curvature of the Spine. 



7. 208. Early Stage of Lateral Curvature. — A spinal column, 

 pelvis, and thorax — macerated, illustrating the above. 



The patient died of disease of the lungs. 



The spinal column is in a somewhat stooping position, and 

 there is a slight curvature with convexity to the left in the 

 dorsal region. The thorax on the right side is compressed, the 

 ribs being approximated. 



Originally entered as an illustration of the form of curva- 

 ture depending upon contraction of the chest from collapse of 

 the lungs. B. C. i. 3. M. 21.

7. 209. Early Stagre of Lateral Curvature.— Cervical dorsal 



and upper part of lumbar portion of a spine, with ribs, and part 

 of manubrium sterni — macerated, illustrating the above. 



A gentle lateral curvature is seen convex to the right 

 from the second dorsal vertebra downwards, and with a slight 

 rotation of the bodies towards the convexity. The ribs on the 

 concave side are, as usual, pressed together, while those on the 

 convex side are separated. Owing to the very slight amount 

 of rotation, the projection backwards of the angles of the ribs 

 on the convex side is only just appreciable, while the flattening
