kind distributed over every region of the globe, each exhibiting 
differences in habits, customs and superficial complexion, Man 
forms but one species, Yomo sapiens, the sole representative of 
the unique genus of his family. ‘Though the genus Homo is 
thus far apparently zoologically isolated, there is a remarkable’ 
group of animals, which we designate ‘“‘ Apes,” and which, 
possessing many of the same structural characters more or less 
modified, stand apart from all the other Mammalia, and make 
a distinct approach to Man. Between Man, however, and the 
Apes, even the untrained eye at once perceives, amid obvious 
marks of inferiority, unmistakable resemblances, while anatomi- 
cal investigations reveal that ‘‘the points in which Man d'ffers 
from the Apes most nearly resembling him, are not of greater 
importance than those in which the Ape differs from other and 
universally acknowledged members of the group.” (#/ower and 
Lydekker.) ‘The Apes, on the other hand, are so nearly related 
to the Monkeys, the Baboons and the Marmosets, by characters 
which insensibly merge into each other that they, along with 
Man, must logically be embraced in the same zoological 
division. The animals known to us as Lemurs, called by the 
Germans “ Half-Apes” and by the French “‘False-Monkeys,” are 
the nearest to the Apes and Man of all the remaining Mammals, 
though there are many points of divergence from the above- 
named groups. The Lemurs, in fact, exhibit considerable 
affinity to lower forms of Mammalia, especially to the In- 
sectivora, but in internal structure and habit they approach 
the Anthropiform* group just referred to—in the flattened 
form of the digits, the opposable great toe, with its ankle- 
bone (the ento-cuneiform) rounded for its articulation, as in the 
higher Apes and Man.
