but become rapidly straighter and shorter until the fourteenth, 

 which is only about one inch and a-half long, and has the 

 slightest possible curvature. The length of the ribs are as 

 follows — but it must be recollected on the view of these 

 dimensions that, except the first, we possess no rib of the left 

 side. Possibly the ribs of left side, if known, would prove 

 smaller than their corresponding ribs. Thus the right trans- 

 verse apophyse of the ninth vertebra is perforated on the side, 

 but not the left one, although there is an open groove in it 

 for the passage of the left tendon. In the same way the 

 thirteenth and fourteenth vertical apophyses are perforated on 

 the right side of the emargination, but on the left side these 

 holes are open as usual, and only grooves. 



OF THE STERNUM. 



Only one of the pieces of the sternum was at first found, and 

 this would appear to be the middle one. It is composed of 

 two bones confluent at one of their sides, as is made evident 

 by a longitudinal medial furrow on the outside. The shape 

 of this piece is unsymmetrical, but quadrilateral, the right 

 component bone being somewhat larger than the left one. 

 The dimensions of the entire bone are as follows :
