Anti-Zebra Scrum

(11) 94 Tests with Anti-Zebra Serum. 



These tests were all made on one day with one antiserum obtained 

 from a rabbit treated with the serum of Equus greyvi Giinther, Grevy's 

 zebra, which died at the Zoological Society's Gardens, London. This 

 antiserum was moderately powerful, giving a precipitum of "012 c.c. with 

 its homologous blood.

Note. A number of the tests here recorded are not included in the 

 tables at the end. The footnote to the preceding tests with anti-donkey 

 serum applies also to these bloods. In addition, the three tests with 

 anti-zebra serum upon the 3 cetacean blood-samples are not included 

 in the tables. 



The close relationship existing between Equus caballtts and a 

 species of zebra (Equus burclielli) has been demonstrated by crossing.
