Anti-Wallaby Serum 



199 



The reactions noted occurred within 40 minutes. 



The reactions of the first and second class were confined to two 

 cetacean bloods, those of Bulaenoptera rostrata, and Phocaena communis. 

 Some medium cloudings are noted amongst the Artiodactyla, some faint 

 cloudings amongst these and other mammalia. 



VII. Antiserum for Marsupialia. 



691 Tests with Anti-Wallaby Serum. 



The antiserum used in these tests was obtained from a rabbit treated 

 with the serum of Onychogale unguifera Gould, the Nail-tailed Wallaby, 

 the animal having died at the Zoological Society's Gardens, London. 

 The antiserum possessed but moderate power, yielding a precipitum of 

 '007 c.c., on being standardized.

* No. 289 gave curious results with other antisera. See tables. 



It will be seen from the above that the action of this antiserum was 

 limited, as far as the large reactions go, to the Macropodidae. The 

 bloods of the latter gave 40 /o of the large reactions, 53 % of the second- 

 class reactions, one gave a faint clouding; in other words, taking the
