The Vertebral Column of the Bushman Race of South Africa. 371 
the vertebrae, the spinous process and lamina overlap each other in a 
much lesser degree in the Bushman, thereby allowing a greater latitude of 
movement in the thoracic resrion. 
Lumbar Begion. Vertebrae Lumbales. 
The various measurements of the bodies and canals are taken as in the 
thoracic vertebrae, and the general lumbar index which indicates the 
amount of curvature of the spine in this region as far as the vertebrae are 
concerned is also added ; thus : —
