Qnatdltatli'c Pnclpitui Tests 



From the above it will be seen that the larger reactions are all 

 confined to Bovidae and Cervidae, although from some cause the last 

 two of these (Nos. 595 and 502) gave low figures. These measui'ements 

 were unfortunately not made in duplicate consecjuently there is no 

 control. Nevertheless the result agrees fairly with those obtained with 

 other antisera of this class. It will be seen that the whale (098) gives 

 a higher figure than either the horse or pig, although the difference 

 is very slight. 



Tests with Anti-Mexican-Deer i:ieniiii (1. \\. "02). 



Antiserum from rabbit treated with the serum of Cariacus 

 inexicatius ((581 ). 



Of other mannnalian bloods, those of Carnivora (11) gave 15 "/o 

 reaction, those of Pi'imates (7) gave 18 "/o reaction, the percentage given 

 being the average for the groups. On the other hand the bloods of 

 Marsupialia (8) all gave no trace of reaction. 



From the above we see that the high jjercentages are confined to 

 Cervidae and Bovidae amongst the Ungulata, The high })ercentages 

 obtained with non-homologous bloods in these groui)s is difficult to 

 inteipret, the blood-relationshiji a])]i(ars very close in any case. The 

 bloods of Sus and Equus give results lemarkably in accord, and both 

 are practically the same as with the Rorqual (Balaenoptera). A very 

 moderate reaction is observed with the bloods of Carnivora and Primates, 

 both being fairly equal, whereas the distance separating the Marsu])ialia 

 is clear from the total absence of reaction with their bloods.
