Tests with Anti-Reindeer ^erton (G. vi. '02). 



The antiserum used in this series was obtained by treating a rabbit 

 with the serum of Rancjifer tarandus (483). Only the bloods of Ungu- 

 lata and that of the whale were tested. Antiserum weak. 



The above figures are fairly conijiarable with th(^se obtained with 

 other antisera for this group. The figures for Capra, Cobus, and ()\is 

 (towards the end of the series) are too low, judging from what has been 

 obtained in other series. The whale on the other hand again gives 

 a remarkably high figure, this being in accord with the qualitative tests 

 on three samples of cetacean blood.
