CHAPTER X 



NOTES ON SMALLPOX, SYPHILIS, CANCER, ETC. 



Cystic disease of the urinary tract. Sometime before 1892 

 representative London pathologists had sought the opinion 

 of T. Spencer Cobbold upon some microscopic bodies found 

 in two instances of disease ; one of these was a condition 

 similar to that of which some details are shown in Fig. 46. 

 Cobbold pronounced the bodies to be " psorosperms," 

 meaning that they were sporozoa of some sort. This opinion 

 was accepted by English pathologists. The fullest account 

 of my case is in Part II, where the difficulty I had in adopting 

 the accepted view is explained. When I realised that it is 

 parasites one sees in those cysts, Fig. 46, 1, I did not think 

 I was merely in presence of a rare disease, which by reason 

 of its rarity would, in itself, have the less importance for 

 mankind ; but I felt that what I was studying was probably 

 a rare manifestation of several common diseases, such as 

 some forms of kidney-disease, papillomas of the bladder, 

 and adenomas of the prostate. 



Last year for the first time I saw Cornu's illustrations 

 of Olpidiopsis ; some of them are suggested in Fig. 15, p. 60.
