 height of the maximum ordinate. The two curves 

 run nearly parallel to each other at a distance of 

 ten units. Only at high values of the abscissa, 

 where the probable error of a determination is very 

 great in the case of haemolysis, is there a little

deviation from parallelism. The parallelism, within 

 the errors of observation, indicates that the sensi- 

 bility of the erythrocytes is distributed in accordance 

 with the law of probabilities, which is the most 

 regular distribution we could expect. 



Even for erythrocytes some observers have 



found that their destruction by means of haemolytic 



** agents goes on according to the monomolecular law 



with progress of time. This law is proved with a
