from potassium to zinc. Monilia made sufficient growth to be 
easily visible to the naked eye in the starch medium containing 
potassium nitrate at a concentration of 0.8 molar or less, while 
at a concentration of 1.33 molar the spores germinated and pro- 
duced microscopic growth. In a starch medium containing cal- 
cium nitrate at a concentration of 0.667 molar, the spores germi- 
nated but produced such a small amount of mycelium that it 
could be observed only with the aid of the microscope., It is 
interesting to note that after three days no germination had taken 
place in this medium. This shows that in such concentrations 
growth is very slow. In all media containing calcium nitrate at 
a concentration of 1.33 molar or less, there was abundant growth.
