 as the result of pressure upon its cartilages. The line, a, shows the point 

 to which the column would reach if its cartilages were natural. Fig. 165 

 represents, 3, the cartilage extended ; Fig. 166, the same, 3 compressed ; 

 the spinous processes, s, being made to approach in the former case, and
