Besides the cranium, the following bones have been 

 secured : — 



1. Both thigh-bones, perfect. These, like the skull, 

 and all the other bones, are characterized bv their unusual 

 thickness, and the great development of all the elevations 

 and depressions for the attachment of muscles. In the 

 Anatomical Museum at Bonn, under the designation of 

 " Giant's-bones," are some recent thigh-bones, with which 

 in thickness the foregoing pretty nearly correspond, al- 

 though they are shorter.
