haptophores of the toxins. This is made clear by refer- 

 ence to the following ideogram : 



Fia. 135. 



In cases in which distinct intoxication of the cell is 

 effected by the toxin molecule, not only do the hap- 

 tophorous groups attach themselves to the adapted hap- 

 tophilic receptors, but the toxophorous groups also find 

 attachment to adapted toxophilic receptors:

 toxophore to the toxophile group, respectively. 



Tt can be conjectured that when the haptophorous 

 groups seize upon the adapted receptors, the cell proc- 

 esses are embarrassed through the inability of the cell 

 to absorb its customary nutrient molecular groups, 

 which are interfered with by the presence of the toxin 

 molecules, which, though adapted for combination with 

 the receptors, are of no use to the cell. To prevent 

 starvation the cell is supposed by Weigert and Ehrlich to
