384 THE CHIGNON FUNGUS. 
this peculiar form ; and it seems to me that we have here 
a pretty complete history of the life of this fungus,— 
namely, the sporular subdividing and assuming an algal 
Fig. 5. form, which in turn 
becomes amecebi- 
form, and furnishes 
ciliated cells that 
supply the earliest 
condition of the 
fungus, as seen in 
Fig. 4, scattered 
over the hair. 
But not satisfied 
with these results, 
I set to work to grow the fungus in sugar and water, 
under constant observation. A rapid enlargement of the 
sporular cells took place, as in the former case, and in 
some of the larger cells the most distinct circulation of 
the granules around the inner circumference of the parent 
cell was witnessed by myself and my friends, and a beau- 
tiful object it was. Finally, I obtained a result similar to 
the former one. 
Fig. 6 represents the appearance of the fungus at the 
end of fourteen days, seen with an 4 inch object-glass- 
Fig. 7 is a portion of the mycelium, taken from the 
part over the hair, more highly magnified with a 1-12th 
object-glass. 
The ends of the filaments seen in Fig. 8 are analogous, 
in fact identical with those forms which I have figured in 
my work on parasitic diseases of the skin as resulting 
from the growth of oidium. The globose head contains 
spores, and is an early stage. The double cell figured in 
the centre was of a green color like many others.
