This explanation also applies to a considerable num- 

 ber of other cases of toxic action. 



It is of interest to note that in all these cases death be-

haves as a reaction which is continually going on, but at a 

 very slow rate until accelerated by the toxic agent. We 

 have assumed this acceleration to consist partly in the 

 increase of the velocity constant and partly in the stopping 

 of the reaction >A, causing a decrease in the sub- 

 stance (M) to which normal permeability (and perhaps 

 other normal properties) are due.
