 tions on 'the viscera of this animal. The literature dealincj 

 with the anatomy of the chimpanzee is pretty extensive, 

 but it is mainly confined to an account of its osteology and

The animal I dissected was 2 feet 2 J inches in height, 

 when measured from the top of the head to the heel. It 

 had all its milk teeth and the first permanent molars. It
