OP THE Bones of the 

 Thoracic and Pelvic 

 Limbs so placed as to 

 show corresponding 

 paPvTS in both. (A. 

 T.) h 



Tlie preaxial borders of 

 both limbs are towards 

 tlie reader's right hand, 

 and the dorsal or tnie ex- 

 tensor surfaces are shown 

 tiiroiighout the whole ex- 

 tent of the limbs. The 

 somewhat artificial repre- 

 sentation given in these 

 figures cannot be obtained 

 from a single view of the 

 specimens in one position, 

 but it is easily brought out 

 by slightly shifting the 

 bones or changing the 

 point of view. The hu- 

 meral tuberosities are 

 separated so as to show 

 them on the borders of the 

 bone. Fig. 110, Thoracic
