PROTOPLASM 



on the Enzymes marked a very important step 

 towards the discovery of the true chemical nature 

 of protoplasm. A special chapter has to be 

 dedicated to these remarkable substances, the 

 properties of which are eminently characteristic 

 of living matter. 



The final result of our discussion is that there 

 are many reasons for maintaining that protoplasm 

 really is of a peculiar chemical constitution, and 

 that it does not merely represent a mechanical 

 structure. But we have to concede that the 

 chemical nature of protoplasm is not founded 

 upon the peculiarities of one particular substance 

 which is characteristic of living protoplasm. There 

 are, we are certain of it, a great number of con- 

 stituents of protoplasm which form the substratum 

 of cell-life.
