382 THE CHIGNON FUNGUS. 
knots the size of pin-points, surrounding the shaft of the 
hair; they are readily felt on drawing the hair through 
the fingers ; they are somewhat difficult to detach. If a 
hair be placed under the microscope with a quarter-inch 
objective, the mass will be seen to be made up of cellular 
bodies surrounding the hair, such as are seen in Fig. 1, 
Fig: L kindly drawn for 
me by Dr. Braxton 
Hicks; F. R. 5. 
It will be seen 
that the mass has 
the appearance of 
a fungus growth, 
of which two dis- 
tinct forms are here 
present, viz., mycelial or filamentous, seen in the central 
part of Fig. 1; and sporular or cellular, seen in Fig. 2, 
which is the outer part of Fig. 1. 
The hair is apparently healthy, and if the slide be 
pressed the mass will break away from 2 
the hair on either side, bringing away 
with it more or less of the satiate: and 
leaving behind a healthy shaft. The 
cells are seen to be of various shapes and sizes. Fig. 3 
gives a good representation of them; they are from aos tO 
xw inch; many are like the torula Fig. 3. 
cells developed from Penicillium. 
Others are larger, undergoing divis- 
ion very actively ; they may be sub- 
divided into two, three, or four parts, 
or much more freely. This indicates 
the assumption by the parasite of an algal condition. In 
watching the mass on the hair carefully, it is evident that
