Preface. 

 The brain of the interesting and well-known chimpanzee 

 " Sally," which lived for eight years in captivity at the Zoolo- 

 gical Gardens in London, has been recently figured and 

 described by Mr. Beddard (11) in his important memoir on 

 the anatomy of this ape, which he considers to be T. calvus; 

 there are, however, several features about this brain which 

 deserve further notice.
