have ripened, is thinly spread upon a glass slide, we find that 
each nucleus has collected round itself the proportion of 
protoplasm which would finally constitute a spore in which 
it stands as a centre, and each such portion has separated from 
those around it, or is in the act of so doing, and has become 
a distinct organism ; for if examined at the right maturing 
moment these young spores may be seen in slow movement, 
and throwing out hyaline pseudopodia which fill with granular 
plasma, with the same amoeboid character which they would 
again exhibit when the ripe spores burst, arid the new swarm- 
cells began the circle of development afresh (Fig. 13). 
A staining taken at this stage presents a beautiful object, 
resembling a tesselated pavement, each polygonal area being 
dotted with its nucleus.
