Ant i- Reindeer Serum

though weakly. Of 3 equine bloods two gave no reaction, one gave a 

 moderate reaction ; the blood of Hyrax gave a negative result. Of the 

 non-ungulate bloods those of the Primates gave the highest percentage 

 of reactions all told. 



(4) 69 Tests tuith Anti-Reindeer Serum. 



This antiserum was obtained by injecting a guinea-pig with the 

 blood and clouded serum of Rangifer tarandus, kindly sent me by 

 Privatdocent Dr Max Liihe from the Zoological Gardens at Konigsberg. 

 The antiserum was unfortunately very weak, yielding only a precipitum 

 of '004 when standardized with its homologous blood. Owing to its 

 limited quantity it was impossible to carry out more than a very small 

 nvnnber of tests, especially as some antiserum was used for the quan- 

 titative tests reported in Section VII.

Other mammalian bloods than those noted were not tested for the 

 reason that the antiserum had become exhausted. Here, as in the 

 preceding table, the Pecora only show greater reactions, the Cervidae 

 giving more of the marked reactions than do the Bovidae. Of the other 

 mammalian sera tested those of a pig, horse. Rorqual (385 Balae- 

 noptera rostrata) gave a faint clouding. All other bloods showed no 

 trace of reaction.
