MANDRILL AND CELEBESIAN APE 



being guarded by sentinels which are posted round its 

 retreats. The voice of the baboon, like the voices of 

 other creatures, has been variously put into descriptive 

 language. An eminent naturalist, clearly with an 

 anti-Teutonic bias, compared it to the German word 

 " Hoch." Various human actions have been ascribed 

 to baboons. It seems probable that they were the 

 origin of the story of the gorillas of Hanno, who referred 

 to them as stone- throwing and living in throngs. When 

 annoyed, or in an offensive mood, this baboon will open 

 its mouth and as it were yawn at a neighbouring 

 baboon ; it is suggested that this yawn is not so much 

 ennui as a desire to prove to the other the length and 

 sharpness of its canines. When still more angry the 

 ape will smite the ground with its hand like an argu- 

 mentative man with his perceptions and feelings 

 heightened by alcohol. 



The sociable though ferocious and omnivorous 

 mandrill, with its blue-ridged nose, is another member 

 of the genus often represented at the Zoo. The most 

 aberrant baboon is the Celebesian Cynopithecus niger, 

 which is the only Eastern baboon ; it is black in hue, 

 smallish in size (as compared with other baboons) and 

 milder in disposition than are the large dog- faced apes 

 of Africa. 



THE GIBRALTAR APE 



This ape, also known as the Barbary ape, Macacus 

 inuus, is the only monkey that occurs now in Europe ; 

 and, as is well known, it is confined to the rock of 

 Gibraltar, which it haunts in very modest numbers. 

 At one time so unfavourable were natural circumstances, 

 or so inveterate the dislike of the inhabitants, that the 

 numbers sank to so low an ebb as three individuals. 

 But in 1893 the Governor of Gibraltar ascertained, and
