Fic. 16.—One-third natural size. Ribs of right side, first, third, seventh and eleventh. 
first from the middle of tubercular facet to sternal extremity is 
2.25 inches, which is relatively short. The fifth, between the 
same points, is 7.12 inches, while the seventh, along outer curve, 
is 10.25 inches. From center of head to center of tubercle of the 
first rib is one inch, which is very nearly the same distance as in the 
corresponding points throughout the series. The ribs, in general, 
have the muscular impressions and processes, and also the angles, 
strongly marked. Their surfaces, in the main, have a crumpled 
and reticulated appearance. 

Fie. 17.—One-third natural size. Scapulee: A, inner face of left; @. acromion ; ¢, 
coracoid process; B, external view of right; mn, neck and supra-scapular notch: C, 
right scapula resting on edge, showing height of spine. 
The scapulz, though badly broken, retain their more important 
points. The longer diameter of the glenoid cavity is 1.37 inches, 
or about the same asin man. The shorter diameter is .87 of an 
inch, making the two distances as 11 to 7. Said surface is more 
concave than in man. 
The coracoid process is long and massive, and is bent downward 
and inward much more than in Castor. It is.75 of an inch long,
