keeps the species separate ; but there is far less fun among 

 the monkeys. The keeper at our Zoo, will, moreover, 

 point out to any one who shows an interest in his charges, 

 the several kinds. Among the catarrhine or old world 

 monkeys he will probably be able to show you examples 

 of the long-tailed Africans (Cercopithccns), and will give 

 one a handful of nuts, all of which the little fellow will 

 tuck away into his mouth and thrust them into his cheek- 

 pouches till he seems to be suffering from a severe attack 

 of the mumps. Then he may be able to show you a 

 long-tailed Indian monkey (Semnopithecus), one of the few 

 kinds of old world monkeys which have no cheek-pouches 

 but have most voluminous and complicated stomachs 

 instead. There is such a dear little fellow of this kind in 

 the Dresden Zoo with black face fringed with light grey 

 hair. He and I are the best of friends. He is intelligent 

 enough to understand my broken German better than 

 many of the Deutschlanders themselves, and is under the 

 firm belief that I have visited Dresden on purpose to 

 bring him cherries and nuts. The keeper will also point 

 out the macaques, which are for the most part from Asia ; 

 and will call them by their names and perhaps point out 

 a particular pig- tailed macaque as the most intelligent of 

 all and the cleverest thief under his charge. The 

 macaques are a hardy race and are highly intelligent. 

 Darwin tells us that a dealer who used to train monkeys 

 to perform offered a far higher price if he was allowed to 

 select one after a few days' trial. When asked how he 

 could ascertain in so short a time which would best suit 

 his purpose, he replied that everything depended upon the 

 power of attention. If a monkey whom he wished to 

 teach something more serious kept looking off to watch a 

 fly on the wall, or turned aside to admire his own tail, or 

 indulged in any frivolities of that sort he was a hopeless
