THE CHIMPANZEE

usually have the same vocal characteristics, and this 

 appears to be the strongest point in favour of 

 assigning them to separate species, but it is not 

 impossible that even this may be waived. 



Leaving this question for others to decide, as they 

 find the evidence to sustain them, we shall, for the 

 present, regard them as one kind, and consider their 

 physical, social and mental status. 



Whether they be all of one species, or divided 

 into many, the same habits, traits, and modes of life 

 prevail throughout the entire group, so that one 

 description will apply to all, so far as we have to 

 deal with them in general. There are many in- 

 cidents to be related elsewhere, which apply to 

 individuals of the special kinds mentioned, but for 

 the present the term chimpanzee is meant to include 

 the whole group, except where it may be otherwise 

 specified.
