140 MAMMARY APPARATUS OF THE MAMMALIA 



forms of the Placentalia is superfluous. In 

 more recent times, numerous other authorities 

 have come to the same result as Huxley, 

 notably Bensley, who on the strength of 

 extremely careful investigations of the teeth 

 and foot-structure of the Marsupials was led 

 to phylogenetic conclusions that often coincide 

 with mine most surprisingly. 



But I have special satisfaction in drawing 

 attention to the fact that very recently 

 Gregory, a pupil of Osborn, on the basis of a 

 critical examination of all the morphological 

 and palieontological data concerning the 

 phylogenesis of Mammals, has come to 

 Huxley's point of view, and that Hill too, in 

 his last contribution on " The Early Develop- 

 ment of the Marsupialia," has furnished new 

 and important proofs of the correctness of the 

 same. 



Where so many investigations, pursued on 

 the most varied organ-systems, have led to 

 such concordant results, it may safely be 

 assumed that they express the true course of 

 phylogenesis.
