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 toxæmias that result from the decomposition of albumens.
