maltose are fermented. In yeast water containing organic 
acids, growth is as rapid as in the sugar nutrient solutions; 
but instead of forming a film, the growth on the surface 
is limited to the margin along the side of the culture flask. 
The cells vary in size from 2 X 10-25& or 3 X 7-8и. 
Gelatin is liquefied. Chlamydospores and muriform many- 
celled spores oceur in acid yeast-water solution. 
Culture 9, Oospora sp?—The colonies of this organism ap- 
pear much like certain white yeasts. They are circular in 
outline and have a more or less wrinkled surface. Growth 
of this organism does not take place by budding; but the 
mycelium, which is dichotomously branched, predominates

in all media. The cells (fig. 9) are elongated, 2-2.5 X 12-15и, 
or short and rectangular, 3-446, In yeast water containing 
organie acids, certain of the cells may become quite large 
and siekle-shaped, 4—5»x(20-30& Мо chlamydospores or 
conidia are found in any of the cultures. When grown in 
Raulin's nutrient sugar solutions the liquid becomes bright 
red in color. This characteristic easily distinguishes this 
organism from the other cultures with mycelial growth. 
Gelatin is liquefied. 
Culture 10, Alternaria, sp?—This organism growing on 
agar forms a membrane of yeast cells and mycelium of a 
flesh-pink color. The yeast cells (fig. 10) vary in size from
