have just mentioned, does not leave the cor- 

 puscles. 



According to Ehrlich, however, the process is not 

 analogous to a staining process, but follows definite 

 laws of chemical combination, there being, in fact, no 

 affinity whatever between the complement and the 

 blood cells or bacteria. Furthermore, according to 

 this authority, the complement always acts through 

 the mediation of the immune body, which possesses 

 two combining groups; one, the cytophile group, 

 combining with the cell, and another, the comple- 

 ment ophile group, combining with the comple- 

 ment. 



From the foregoing statements it is now evident 

 that Ehrlich and Bordet differ as to their belief in 

 the existence of the complementophile group of the 

 immune body and the haptophore group of the com- 

 plement. A schematic exposition of the relation 

 existing between the cell, immune body and com- 

 plement, according to the views of Ehrlich and of 

 Bordet, is given in the figures below:
