have only oue articulatiug surface for each rib. All the ribs are 

 more or less arched, 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 transverse 

 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. 



OP THE STEENIJM. 



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 :
