eight times the breadth of the broadest rib, and equal to the 

 length of the cubitus from the summit of the olecranon to the 

 carpal articulation. 



The sum of the breadths of the ribs where broadest and the 

 ulnar length of the cubitus, the longest bone in the body of the 

 Camel, exceed the greatest width of the chest by the common 

 difference of the 4 longitudinal dimensions of the cranium. 

 The width of the chest, as stated below, is equal to the greatest 

 length of the head. The costal breadths and the length of the 

 cubitus are therefore 5th proportionals to the 4 longitudinal 

 dimensions of the cranium. 



It will be observed in the Tables, that the ribs on the right 

 side have been more ossified than those on the left. 



Of the Cavity of the Thorax and of the Sternum. 



The cartilages of the ribs being entire in the animal examined, 

 the dimensions of the cavity of the chest are seen to agree with 

 those of the separate bones of the body. 



The greatest width of the chest is equal to the greatest length 

 of the head. 



The length of the sternum is three fourths of the greatest 

 thickness of the body, namely, from the caudal end of the 

 sternum to the summit of the hump at the 6th dorsal ver- 

 tebra. 



The length of the caudal portion of the sternum is twice the 

 length of the 3rd and of the 5th portions ; and is equal to the 

 distance between the inner margins of the orbits. 



The rostral breadth of the caudal portion of the sternum is 

 twice its caudal breadth, and also twice its rostral thickness. 



The thicknesses of the other portions of the sternum increase 

 by regular augments as they approach the caudal portion.
