 have something human-like in their appearance. The Chim- 

 panzee and Orang approximate man in size, and the Go- 

 rilla is vastly more bulky than a man. 



* Huxley, who includes both Man and the. Quadrumana in one order, the 

 Order of Primates, divides that order into three Sub-orders, thus : 



iAnthropidse (Man). 

 Simiadse (Apes and Monkeys). 

 Lemuridne (Lemurs). 



Dr. Theodore Gill (see Arrangement of Families of Mammals, Smithso- 

 nian Miscellaneous Collections), divides the Primates into two Sub-orders : 



1. Anthropoidea (Man and Monkeys). 



2. Prosimias (Lemurs, Tarsiers, Aye-Aye, etc.).
