possibility that, in the organ used, substances are 

 inherent which are also contained in other organs. In 

 saying this we are thinking of such a case as the 

 following. It may be that an individual has 

 some diseased connective tissue in some part of his 

 body. The supporting tissues of the organism also 

 have their metabolism, and are quite able to give off 

 disharmonious products into the blood, especially if 

 they are profoundly altered or broken down. Every 

 organ contains connective tissues, though whether 

 they possess an organically specific structure is 

 highly doubtful. It would certainly be of the 

 greatest importance, if so-called failures were tested 

 with connective tissue pure and simple, and then with 

 the corresponding organ without its connective 

 tissue. It would also be advisable, in the case of 

 unexpected results, to test with the albumens of 

 blood serum, and those of blood corpuscles. Studies 

 of this kind will lead much more quickly to clear 

 results than the hurried collection of data which have 

 probably been all subject to the same source of error. 

 Amongst other observations which have been

communicated up to the present time we shall refer 

 to the following. Epstein found that out of thirty- 

 seven cases of cancerous patients all but one, 

 originating from a cachectic patient, aged So, 

 decomposed the coagulated albumen of carcinoma, 

 while in no one case was the albumen of placenta
