and a Flagellate (Chilomonas paramcecium). The results of im- 

 pregnation may be briefly summarised. 



In the case of those protozoa possessing simple contractile 

 vacuoles, such as the Peritricha studied, and forms of the Holo-

tricha like Lionotus folium and Nassula lateritia, the contractile 

 vacuole wall was deeply impregnated in all stages from systole to 

 diastole. In Paramoecium caudatum, in which there is present a 

 compound contractile vacuole consisting of the central reservoir 

 and its contributory canals, the impregnation occurred not only 

 around the central reservoir but also in the walls of the canals,
