DEVIATION OF THE ALEXIN IN HEMOLYSIS.

the corpuscles, but too little to produce an abundant precipitate, had 

 been put in tube A we should expect that hemolysis would have 

 taken place. This may be experimentally verified. In a tube 

 containing 0.025 of a cubic centimeter of ox serum, 0.05 of a cubic 

 centimeter of corpuscles and only 0.2 of a cubic centimeter of 

 immune serum, hemolysis occurs as well as in a control that con- 

 tains no ox serum. 



In such experiments, however, it is evident that if the amount of 

 rabbit > ox serum is too much diminished no hemolysis will occur 

 owing to the fact that the corpuscles are not sufficiently sensitized. 



In the following tables are given the results of experiments in 

 which the amounts of rabbit > ox serum vary. In table A the 

 mixtures contain ox serum; in B there is no ox serum, but salt 

 solution in its place; the doses of ox corpuscles and rabbit alexin 

 are constant.
