AFRICAN BABOONS 
‘n which two of the toes are united by a web; of this 
gibbon there have been examples at the Zoo, and may 
be at the present moment. The hoolock is easily tamed, 
and is not as a rule very vicious. A female lately in- 
habiting the ape house showed a positive dis'ike to 
her own sex in the human species, but put up with the 
attentions of men. In India the animal appears to 
be often tamed, and will reside in a “ compound ”’ for 
years. Under these circumstances, Dr. Candler tells 
us, it seldom uses its voice, the need for this expression 
of opinion having departed with the rest of the herd. 
At the Zoo, on the other hand, the gibbon makes 
vocal the ape house, stimulated thereto, it may be 
surmised, by adjacent chimpanzees, and by the con- 
versation of the keeper and of visitors. 
THE CHACMA BABOON. 
This is a necessary abbreviation of the Hottentot 
word “ T’chatikamma,” which is really not pronounce- 
able by us, and is, moreover, a trifle difficult of correct 
spelling. The name refers to the baboon, Pafio por- 
carvus, which with twelve other species inhabits Africa. 
The chacma, and baboons generally, lie at the base of 
the Catarrhine series, or Old World apes. They have 
the cheek pouches, the downward looking and approxi- 
mated nostrils, and the thirty-two teeth, disposed as 
in man, and the non-prehensile tails of that division 
of apes. The baboons differ from other Catarrhines 
by their “very dog-like face,’ by the rather swollen 
muzzle, and by the large size of the posterior callosities. 
The males have also particularly large canine teeth. The 
tail is short. Our chacma, which is always to be seen 
at the Zoo, and has recently been placed outside instead 
of inside the stuffy monkey house, lives in the South of 
Africa in troops up to about 100 in number. This
