I. Introductory. 



UUEING the last year the Society has lost two of the most valuable and interesting 

 Anthropoid Apes from its collection — viz., the Bald-headed Chimpanzee " Sally " and 

 the Lesser Orang " George." As neither of these forms has been investigated anato- 

 mically, except as regards the skeleton, I desire to offer to the Society some account 

 of their structure as an addition to the existing knowledge of the Anthropoid Apes. 

 Indeed, these are about the only two forms of the structure of the soft parts of which 

 we have at present absolutely no knowledge. Unfortunately both animals were in 

 certain respects in an unfavourable condition for dissection. The viscera of the 

 Chimpanzee were very greatly diseased, while the enormous quantity of fat deposited 

 round the abdominal viscera of the Orang rendered their condition if possible stQl more 

 unfavourable for examination. 



The Chimpanzee " Sally," as is well known, lived for a longer time in the Society's 

 Gardens than has been recorded of any other Anthropoid Ape. She was purchased in 

 October 1883, and died in August 1891, having thus been with us for eight years and 

 some months. For notices of the character and intelligence of this animal, the reader 

 is referred to papers by Mr. A. D. Bartlett ' and Mr. Romanes ^ Immediately 

 after the death of the animal Mr. Smit made some careful drawings of the hands and 

 feet and other external characters, which I now exhibit (Plates XX.-XXII.). A figure 

 used in illustration of Mr. Bartlett's paper upon the Ape shows the general aspect and
