ON THE ANATOMY OF THE 



lages of the eighth pair, unite below the last piece 

 of the sternum, (which was here cartilaginous,) as in 

 this figure, a a. 



The sternum consists of five pieces. The figure 

 of the fourth piece is nearly globular, (as at b)« 

 The different pieces were united by cartilage ; the 

 xiphoid measured 1.3 inch, and the whole sternum 

 4.2 inches. 



The general curvature of the vertebral column 

 and of the ribs, does not materially differ from the 

 human subject. The chest appears to be rather 

 more roomy below, in proportion to its upper diame- 

 ter ; and the lower lumbar vertebrae are more sud- 

 denly inclined backward, to enlarge the brim of the 

 pelvis. The following are the dimensions of the 

 thorax. 



Circumference of the thorax at its widest part, i RChes * 

 when the skin is removed, - — 18.0 



Diameter from the root of xiphoid cartilage, 

 to the external side of the 8th rib, = 6.0 



Lateral diameter of the thorax at the 2d false 

 rib, - = 6.5
