over the entire surface: in agar streak culture there is abundant 
massive growth, glistening and faintly tinged with yellow: milk is 
coagulated on the fifth day, the curd solid with a yellowish cast, and 
per cent. of acidity 0.8: on potato a dry, beady, raised and dirty 
yellow growth: in fermentation tube no gas is produced in glucose 
bouillon, growth only in the open arm of the tube: grows well in 
Uschinsky’s media, a ring of yellow color being deposited around the 
upper part of the tube: bouillon becomes slightly turbid, with thick 
zoogloea. 
MICROCOCCUS MELLEUS grandinis.— Found in hailstones: a coccus, 
occurring singly, about 1” in diameter: non-motile: no spore forma- 
tion observed: grows well at 20°C., feebly at 37°C.: aerobic: will not 
grow in hydrogen (Novy’s method): does not liquefy gelatine: yellow 
(melleus)?: stains readily with all the anilines : in gelatine plate cultures 
the surface colony small, about 1™™ in diameter; with an irregular 
margin, the outer portion a darker yellow than the center, granular ; 
the submerged colony round, edges irregularly indented, contents 
granular: in gelatine stick culture a thin feather-like growth along 
the line of puncture, growth spreading irregularly on the surface, 
amber colored: in agar streak culture grows abundantly as a raised, 
glistening, and amber yellow-colored growth: when touched with a 
needle the growth adheres and can be drawn out in a long string: 
milk is not coagulated, and there is no acidity: on potato a dry 
raised growth, bright amber color, growth slow: in fermentation tube 
no gas is produced, and growth is only in the open arm of the tube: 
grows slowly in Uschinsky’s media, a zooglcea of a pale yellow color 
being formed: in bouillon a slimy mass is formed that settles to the 
bottom of the tube.— F. C. Harrison, Guelph, Ontario.
