 much higher (note the percentages) than in the other mammalia when 

 the number of bloods examined is taken into account.

It is worthy of note, that the tests made with the three preceding 

 antisera for Carnivora agree in causing a larger proportion of reactions 

 amongst the Primates than amongst any of the other mammalia, 

 excepting the results with anti-hyaena serum which show a large 

 proportion of ftiint reactions amongst the Ungulata. 



One of the two rodent bloods giving a x reaction again proved to 

 be No. 257 referred to under anti-hyaena serum. 



(4) 358 Tests with Anti-Seal Serum. 



The antiserum used in the following tests was obtained by treating 

 a rabbit with the serum of Phoca vitidina L., the Common Seal (No. 242). 

 The antiserum was weak, only giving a precipitum measuring "006 c.c. 

 Avhen "1 c.c. of antiserum was added to '5 c.c. of a 1 : 100 dilution of 

 homologous serum.
