SMALLPOX, SYPHILIS, CANCER, ETC. 167 



was laid the foundation of the delusive Chlamydozoa- 

 theory of von Prowazek. 



Again, in an article published in the British Medical 

 Journal, 10th Dec. 1892, Metchnikoff left the impression 

 that he regarded as coccidial the bodies described by Souda- 

 kewich in cancers. In the next issue appeared a letter of 

 mine stating that they are not coccidia " in the biological 

 sense of the word." 



At the present time one investigator writing with seeming 

 indifference to the history of the subject, and apparent 

 neglect to examine epithelial lesions, claims Cytoryctes luis 

 as a Coccidium. 



This protozoon has had such a disastrous effect on 

 pathology that I am almost ashamed to have given the 

 first description of its early microgametogenesis. 



The sporozoa idea not only diverted me from the right 

 path but also led me into error ; thus in 1893, in the course 

 of an examination of an adenoma of a cat's lip among the 

 sections of the tumour which show cysts that contain bodies 

 like those of cystic ureteritis, another of a seminal vesicle 

 of an earthworm found its way, probably from the razor 

 of the microtome. Too keen on the mistaken trail of 

 Sporozoa it was this particular section that, not suspecting 

 what it was, I chose to show at a meeting of the Pathological 

 Society, arid a drawing of it disfigures p. 93 of my " Morbid 

 Growths and Sporozoa." 



So long as I accepted Olpidiiforma and kindred bodies
