FIG. 84. 

 Resolution of Euglense into smaller Organisms. ( x 6co.) 



a. Euglena in its active state. 



b. Euglena contracted and about to encyst itself. 



c. Colourless spherical outgrowth from transforming Euglena. 



d. Subsequent stage outgrowth elongated and containing irregularly 



disposed solid matter, which gradually aggregates itself into 

 spherules (e), each of these afterwards becoming enclosed within 

 one of the units into which the mass segments. These subse- 

 quently liberate themselves as active Monads (g), which gradually 

 assume the forms of h, j, and k ; whilst the latter motionless form 

 either develops cilia (/), or else becomes fluent and moves about 

 as an Amoeba (m). 



n. Another form of outgrowth from transforming Euglena constituting 

 a brown, tuberculated Fungus-sporangium. 



o. Resolution of Euglena into Monads, partly green. 



p Resolution of Euglena into Algoid Corpuscles and Bacteria. 



q. Resolution of Euglena into Diatoms.
