15 BASED PRIMARILY ON THE RELATION 

 OF A STRAIGHT LINE TO THE GREATER 

 PORTION OF THE VERTEBRAL BORDER 

 BELOW THE 5CAPOLAR SPINE . 



THE CONVLX TYPE' MAY &E 

 REGULARLY OR IRREGULARLY,

and Suggests Useful Symbols for Recording the Straight and the Varying 



Degrees of Convexity and Concavity 



Note the relation of the greater portion of the vertebral border below spine to the 



adjacent line in A, B and C. For comparison each scapula is posed with its long axis 



resting on a vertical line.
