inch, possessed no trace of a contractile vesicle, no food- 

 balls, a few of the linear bodies, some of the nuclear- 

 looking bodies and nothing that could be differentiated 

 as the original nucleus. Tne nuclear-looking bodies were 

 granular, as the ones cited above, and instead of being 

 free in the endoplasm, were congregated in five spheri- 

 cal masses, each mass being composed of from four to six 

 units and was enclosed in a very distinct raembtane, 

 which was made even more distinct by adherent granules. 



In a short while and without any apparent move- 

 ment of the body, three of these spherical masses were 

 thrown out with some force; the fissure in the ectoplasm 

 of the encysted amoeba was not closed; and the whole 

 form collapsed, still containing two of the masses. In 

 about fifteen minutes after being ejected, the membran- 

 eous coverings of the units were ruptured and the con- 

 tained nuclear-looking bodies were freed. The average 

 size and appearance of these bodies were the same as the 

 ones seen discharged from the amoeba first recorded. In 

 the course of a few minutes they were seen to go through 

 identically the same phenomena as was observed to take 

 place with the one first mentioned. The field was now 

 tilled with these zoospores, and being free from all other 

 forms of life, offered a good opportunity for further study. 



In about three hours after beginning the observation, 

 some of the zoospores had slackened their movements, 

 would come to a halt for a short while, and then start 

 off again; a number were less active than the rest and in 

 a short while became quiescent. Selecting a (];iiet speci 

 men that measured 1-2000 inch and using ;; -\ objective it 

 could be distinctly seen to elongate itsrlf and then re- 

 sume its original size; would throw out a single minute 

 lobate process now from one side and again from the 

 other side. The dark blue mass of aggregated gran- 

 ules first observed in the nuclear-looking bodies after 

 they had been ejected from the amoeba, had become
