In his famous book on _The Expression of the Emotions in Man and
Animals_ (1872) Charles Darwin showed that many forms of facial
expression familiar in man have their counterparts in apes and other
mammals. He also showed how important the movements of expression are as
means of communication between mother and offspring, mate and mate, kith
and kin.
The anthropoid apes show notable differences of temperament as the
photographs show. The chimpanzee is lively, cheerful, and educable. The
orang is also mild of temper, but often and naturally appears melancholy
in captivity. This is not suggested, however, by our photograph of the
adult. Both chimpanzee and orang are markedly contrasted with the fierce
and gloomy gorilla.]
