546 WILD ANIMALS. 



can understand, and ever afterwards will probably ignore the re- 

 flection altogether. That there is no reality about it they appear to 

 be perfectly aware. The sense of smell being one of their principal 

 guides, almost more so than that of vision, they readily discover the 

 cheat, and so it may be with the chimpanzee, and the reflection 

 through being only visible and not detected by the other senses 

 may not conjure up any suggestion of another animal. This 

 fact was to some extent demonstrated by Mr. Brown himself, for 

 in a previous article on the intelligence of this species of ape, he 

 stated that he had placed a looking-glass in the cage with the 

 two animals. They at first took no notice of it, but, one of them, 

 finding the reflected image engaged evidently in the same occupa- 

 tion as himself began to watch it carefully " until he seemingly 

 became satisfied that what he saw was in some manner to him in- 

 comprehensible." If this were not so, the memory of the dead 

 companion, even if there were no actual grief at her loss, would 

 have elicited some recognition, for if sorrow is only very transient, 

 their memory is certainly of a more permanent character. This, 

 it may be said, has been proved on many occasions by their recog- 

 nizing with signs of extreme pleasure certain keepers who have 

 been long absent from them. 



These apes also express their pleasure in a very human-like 

 manner. A few years ago, the Zoological Society owned a female 

 chimpanzee, and some time after she had been in their possession, 

 they procured a male companion for her. Their introduction to 

 each other was described at the time as a most amusing incident. 

 The two creatures rushed into each other's arms after the 

 approved method of stage lovers under similar circumstances. 

 They rubbed their heads together, and kissed one another. Then 

 the gentleman affectionately patted the maiden's face, danced 

 round her, caught her about the waist with the fervour of his 

 dehght, exactly as if he were going to waltz with her, and then 

 they both proceeded to express their mutual satisfaction at their 

 chance encounter so far from home by dancing round the cage 

 and howling in ludicrous concert. 



" Sally," which is the name that has been given to the well- 

 known chimpanzee now in the Zoological Society's collection, and
