The comparison includes the following animals: —

3. Chimpanzee (mean of two). 



4 Macacus Rhesus (mean of two). 



5. Macacus cynomolgus. 



6. Cynocephalus Hamad ry as (Hepi, or Lion Baboon). 



7. Papio Maimon (Mandrill). 



8. Ateles ater (mean of two). (Spider Monkey.)

 in spirits by Captain J. B. Walker, F. R. G. S., from Africa.
