circumstances. It is evident that much might be done with the chim- 

 panzee to make him an agreeable companion to man. Fortunately, this 

 hard fate may be spared to the chimpanzee, because he cannot support 

 existence in the colder regions to which our race has become acclimated.

The negroes do not seem to court his companionship. One notable feat- 

 ure in the chimpanzee remains to be stated, and that is his peculiar 

 behavior to other animals. He is perfectly contemptuous in his treat- 

 ment of our small, domestic animals, such as rabbits. He is frightened 

 at large and fierce dogs, and exhibits an extreme terror at snakes and 

 ugly reptiles. In this latter fact we recognize a mental state which is 

 still shared by man, suggesting the probable origin of the serpent as an 

 embodiment of the devil in the ideas of primitive man, and which still 

 survives among us at the present day. Another species of man-ape is 

 the tschego {Anthropopithicus tsehego), which is only known from a 

 single living female brought to Dresden from Loango. This species 

 seems to be but little smaller than the gorilla, intermediate in size be- 

 tween this and the chimpanzee. In the proportion of its parts the most 

 notable peculiarity seems to be that the legs are longer than in the 

 other man-apes. The behavior of the specimen in confinement did not 

 differ greatly from that already related of the chimpanzee. 



The Asiatic man-apes differ from those of Africa by the proportion- 

 ally longer arms, which reach down to the ankles. The orang-outang 

 (Simia satyrus) inhabits most commonly the island of Borneo, and has 

 recently been collected in considerable numbers by Mr. Alfred Wallace. 

 It has only twelve pairs of ribs, as is usual with man. The body is 

 broad at the hips, and joined to a pyramidal-shaped head by a short 

 neck, which is still further concealed by heavy folds of the skin, which 

 can be puffed out by the animal when angry. The eyes and ears are
