106 PROTISTS AND DISEASE 



6. Vacuoles. These I have seen once as sketched in 

 Fig. 29, i. The granules between the vacuoles were in a 

 state of oscillation or Brownian movement. I have seen 

 a similar appearance in a sclerotium of Badhamia utricularis 

 after it had been 12 hours in water. 



7. Flagellate Bodies. This striking feature I have only 

 once observed in a culture on the fourth day. The material 

 was from abundant lesions, some of which I heaped up in 

 the hollow of one of the cupped slides for hanging-drop 

 preparations, and placed in a moist chamber as shown in 

 Fig. 28. The result I described in the Centralblatt fur 

 Bakteriologie, 1895, vol. i. p. 245. 



The description, slightly condensed, runs 

 " The most remarkable appearance consists in the 

 presence of a great number of actively-moving flagellate 

 bodies. They have a roundish head of the size of a red 

 blood corpuscle, and a single powerful flagellum, and under 

 a one-twelfth immersion lens were easily seen and un- 

 mistakable ; many passed across the microscopic field and 

 then escaped from sight. Many of the molluscum bodies 

 were unchanged ; of others, but a thin shell remained ; 

 still others had apparently undergone a liquefaction in their 

 central part, and in this area were numerous highly-refracting 

 oscillating granules." 



I may add that in what I called the " heads " of the 

 motile bodies Fig. 29, Jc, there were moving granules quite 

 like those in the molluscum bodies. The " heads " may be
