OBSERVATIONS. 



Phaseolomyidae (Marsupials and Pronogrades) should 

 exhibit a liver in some instances primitive in character — • 

 in some almost indistinguishable from the human — and 

 in some intermediate, in type, between the two. As I 

 have already pointed out, the internal arrangement of 

 the Wombat's abdomen approximates closely to the 

 human, and this is especially noteworthy as regards the 

 spleen, pancreas, and the vermiform appendage, as well 

 as the liver.
