measuring a quarter of an inch in thickness and three fourths of 
asinch in circumference, collected on the surface of the medium 
instab and slant cultures. In case of stab cultures the agar was 
broken vertically along the line of inoculation. The colorless 
growth followed this break in the agar, and as the substratum 
vecame hard the mass collected as a colorless semi-fluid in the 
bottom of the test tube. 
On slant agar there was a thin colorless layer, imparting a 
fuorescent hue to the medium. In agar plate cultures the 
oganism formed small round colonies about the size of a pin 
tead, resembling a small drop of water. These colonies were 
‘ometimes found with the disease germ, in plate cultures taken 
directly from the beet. It also grew on sterilized potato, and 
‘0 some extent on gelatin. Immediately after separation from 
the beet root the organism produced fermentation, but the power 
Was lost after a time. Staining revealed only a structureless
