by means of other methods, will be brought into line 

 with those acquired by means of the new methods. 

 Thus the discovery, by Hermann Pfeiffer and his 

 pupils, of the existence of toxic compounds in the 

 urine in certain diseases and in certain conditions, 

 should suggest to us that the products, which are 

 formed by the defensive ferments, are also finally 

 excreted. The comparative investigation of the 

 dialysates, however, will have to decide whether there 

 are direct relations of any kind between such products 

 of decomposition and the poisonous components of 

 the urine, and whether we are right in speaking of 

 toxaemias that result from the decomposition of 

 albumens.
