II. Tests with Anti-Insectivore Sera. 



These tests were conducted with but a single antiserum, 383 bloods 

 being examined. Maximum reactions were only obtained with the 

 blood of Erinaceus, whilst slight reactions were only obtained with a 

 very few (3'5 %) of all the other bloods examined, although the anti- 

 serum was very powerful. 



III. Tests with Anti-Carnivore Sera. 



Four antisera were used in this group : anti-cat (785 tests), anti- 

 hyaena (378 tests), anti-dog (777 tests), anti-seal (358 tests). The 

 results in all four cases agreed in showing a preponderance of larger 

 reactions amongst the bloods of Carnivora, as distinguished from other 

 Mammalia, maximum reactions usually taking place amongst more 

 closely related forms in the sense of descriptive zoology. 



IV. Tests with Anti-Ungulate Sera: (a) Artiodactyla. 



1. Anti-pig serum (818 tests) only gave maximum reactions with 

 bloods of Suidae, moderate reactions with those of Pecora and Tylopoda. 

 Of the bloods of the Artiodactyla, as a whole, 66 /o reacted in some 

 degree. Owing to the power of the antisera used a " mammalian 

 reaction " was frequently observed, 51 % of the non-ungulate bloods 

 giving slight reactions. All of the three cetacean bloods examined 

 gave a moderate or slight reaction. 



2. Anti-llama serum (363 tests) only gave maximum reactions with 

 its homologous blood, moderate reactions with the bloods of an allied 

 species and that of Camelus. The percentage of slight reactions was 

 high only amongst Ungulata. 



3. A considerable number of antisera were prepared for Pecora, 

 and tested on a large number of bloods :
