With these points in view the following experiments were 

 undertaken, the arrangement of which is evident from the tables.

It is evident from the results of the tests of 40 sera collected 

 at random over a period of several months that none of them, 

 in the quantity used, contained a sufficient amount of natural 

 amboceptor to cause hsemolysis when brought in contact with 

 red corpuscles of monkey and guinea pig's complement. How- 

 ever, the majority of the same sera contained a considerable 

 amount of antisheep natural hasmolytic amboceptor. 



ANTIMONKEY HEMOLYTIC AMBOCEPTOR 



The difficulty in production of high-value antihuman hsemolytic 

 amboceptor has been already mentioned in this paper. In our 

 experience the average number of injections necessary to produce 

 useful serum amounted to at least five injections and the resulting
