196 THE BEGINNINGS OF IIFE. 



meshes -g-^o^" in diameter, at first made their appear- 

 ance, and after a lapse of twelve hours the individual 

 units became more distinct and began to assume an 

 oval form. Whilst still aggregated together, they were 

 noticed slightly to increase in size. After a time they 

 separated from one another, and then began to elongate 

 into filaments which gradually displayed the characters 

 of Fenki Ilium glaucum. Pineau pointed out that the re- 

 semblance between these inferior members of the ani- 

 mal and of the vegetable kingdoms is so close, ^qu'il 

 est impossible de distinguer une monade d'un globule 

 mycodermique dans les premieres phases de leur de- 

 veloppement.' 



The specimens of Monas lens made their appearance 

 in a pellicle which formed on an infusion of veal. 

 They appeared first in the midst of it ^ as an indistinct 

 areolar network, the meshes of which were about g-gVu-" 

 in diameter.' This network gradually became more 

 distinct, owing to the contours of its component cells 

 becoming more clearly defined. These at last separated 

 from one another, and then each revealed a fine whip- 

 like filament proceeding from a part of its circumfer- 

 ence. The individual corpuscles, which were at first 

 quite stationary and in contact with one another, ex- 

 hibited slow oscillating movements as they separated ^. 



^ He says, one sees first ' de petits amas de granulations dont les 

 contours commen9aient par etre diffus ; peu a peu ces amas devenaient 

 plus nettement circonscrit et ils finissaient par acquerir I'aspect de 

 v^ritables Monades, d'abord immobile, puis douees de mouvement.'
