IV. — MAMMALIA. 21 



Other respects they are so similar in structure to men that the 

 Bimana and Quadrumana are now placed in one order and called 

 Primates. But for convenience the older classification is here 

 retained, as being more generally understood. 



The MONKEYS are represented in the Museum by the 

 Anthropoid, or manlike Apes— viz. the Gorilla, the Orang- 

 Outang, the Chimpanzee, the Gibbon, and by other Monkeys less 

 like man. 



The Gorilla {Troglodytes gorilla) is represented by specimens 

 in a case between the pillars at the north side of the Central 

 Hall and by a skeleton in the Osteological collection. It is the 

 most manlike of the Monkeys, but its ferocious appearance shows 

 it to be far below even the lowest men. It is a native of Western 

 Africa. Many tales are told of its daring and its encounters with 

 travellers in the African forests. The ordinary height of the 

 Gorilla is about five feet six inches. The jaws are of tremendous 

 weight and power. The huge eye-teeth or canines of the male, 

 which are fully exhibited when, in his rage, he draws back his 

 lips and shows the red colour of the inside of his mouth, lend 

 additional ferocity to his aspect. The arms are very long and 

 powerful, extending nearly as low as the knees. The legs are 

 short and decrease in size from below the knee to the ankle, 

 having no calf. The great length of the arms and the shortness of 

 the legs form two of the chief differences between it and man. From 

 the structure of its skeleton, the Gorilla is not adapted for the erect 

 posture ; its favorite attitude is semi-erect with the weight partly 

 resting on the knuckles of its long arms, and in this way it 

 swings itself along as with a pair of crutches. It has been seen, 

 however, to walk with its hands clasped across the back of its 

 head and when enraged it is said to stand erect beating its chest 

 with its hands. 



The Chimpanzee {Troglodytes 7iiger) is also a native of 

 Africa. It is a much less formidable animal than the Gorilla, 

 although it is quite able to defend itself against its foes in the 

 forest. A specimen is to be seen in one of the cases in the gallery 

 of the " Old Wing."
