It folloAvs from these experiments that two injections of 

 monl^ey's red cells are sufficient to produce serum of 100 hsemo- 

 lytic units per cubic centimeter, which is useful serum for tests. 

 This can be accomplished within thirteen days, using not more 

 than from 2.5 cubic centimeters to 3 cubic centimeters of blood. 



In Table II the results of comparative tests are given. In 

 one series antihuman amboceptor and human red cells were used ; 

 in the other the same specimens of blood were subjected to a 

 test in which antimonkey hsemolytic system was employed. 

 Otherwise the arrangement of the tests was identical in both 

 series.

Table II shows that the results of the complement fixation 

 test with antimonkey amboceptor and monkey's red cells were 

 identical with those obtained when antihuman hsemolytic system 

 was employed. "^^
