THE ZOOLOGICAL SOOIETY. 197 



It dealt with some remarkable hybrids, of which the table below 

 gives the pedigree: 



Zebu (^— T— Gayal ? 



A. Hybrid $ (Zebu S x Gayal ?) Bison ^

B. Hybrid $ (Zebu <$ x Gayal ? x Bison cj) Bison ^

C. Hybrid 9 ... (Zebu (^ x Gayal ? x Bison ^ x Bison ^) 

 Born March 12, 1884. 



That is, the last hybrid was of one- eighth zebu and one- 

 eighth gayal blood and three-quarters bison, so that the state- 

 ment that the calf was " undistinguishable from a pure-bred 

 bison of the same age " causes no surprise. To a zebu bull the 

 hybrid A. produced four other calves, of three-quarters zebu 

 and quarter gayal blood, but with these nothing appears to 

 have been done ; nor were further experiments encouraged. In 

 commenting on the omission of the authorities to turn the 

 collection to practical account, Mr. W. B. Tegetmeier wrote in 

 the Field of January 14, 1899 : 



It is greatly to be regretted that we have not in England, in the 

 Zoological Gardens or elsewhere, any place where experiments or observa- 

 tions on the valuable results that might attend the hybridisation of our 

 domestic animals might be studied. Mr. Bartlett's hybrid bovines should 

 have been utilised. There is no doubt that in the hands of a successful 

 breeder, they might, under some conditions or circumstances, have greatly 

 tended to the improvement of our domestic cattle. 



In the volume for 1885 Bartlett's paper on Sally, the famous 

 chimpanzee, appeared. This dealt with her physical character 

 and her fondness for animal food; her mental qualities were 

 discussed by Romanes in a paper in the volume for 1899. 



Of the prosectorial papers forty-six were contributed by 

 Mr. F. E. Beddard and twenty-four by W. A. Forbes ; from Mr. 

 J. Bland Sutton came several pathological papers of interest. 

 That on the Diseases of Monkeys opens with the following 

 important passage : 



When a "generally received opinion" is made the subject [of careful 

 investigation, it not infrequently turns out to be erroneous. So with
