hair. The largest specimen measured is said to have been 

 about one hundred and twenty-five centimeters high. Troglo- 

 dytes niger, the chimpanzee (Fig. 393), is a native of western 

 and central Africa; it is usually black in color and attains a 

 height of about one 

 hundred and fifty 

 centimeters. The 

 gorilla, Troglodytes 

 gorilla (Fig. 394), 

 is likewise a native 

 of Africa ; its hair 

 is dark gray in color 

 and it may exceed 

 the height of the 

 chimpanzee by fif- 

 teen or twenty cen- 

 timeters. These 

 three largest apes 

 are all more or less 

 arboreal, make nests 

 for themselves in 

 the branches, and 

 feed chiefly on fruits 

 and twigs. Which 

 one most resembles 

 man it is difficult to 

 say. The orang has 

 relatively longer 

 arms than the other 

 two, but its brain 

 is apparently more 

 highly developed. 



Man, Homo sapi- 

 ens, displays many 

 points of resemblance to these anthropoid apes, but also several 

 very fundamental differences. The arms are relatively shorter 

 than in the apes, the thumb is longer and more mobile, the great 

 toe cannot be approximated to the others. The hair is very 

 unequally distributed over the body, the erect position is easiest
