ii 4 PROTOZOA AND DISEASE 



growths which contain bodies that I regard as protozoa in masses, 

 such as are fairly represented in Fig. 41, that I based my opinion 

 that about one-third of the weight of such growths consists of 

 protozoa. At the time (1893) it was thought that I could not be 

 speaking seriously. I repeat my opinion here, and no words were 

 ever more seriously intended.
