148 STORRS AGRICULTURAL EXPERIMENT STATION. 
Miik.—Rendered alkaline and curdled at 20°, but not at 37°. Digestion 
occurs later and the milk has a strong odor. 
Potato.—A filiform, raised, smooth, white, luxuriant growth. 
Grows at 20° and only slightly at 37°. Aerobic. 
Bact. lactis plicatumn.s. A non-acid, white, liquefying Bacterium. Isolated 
from milk by Harding. 
Morphology.—Size, 3u-5u x .8u-.94, growing in long chains. No spores, no 
capsules, and Gram stain irregular. 
Gelatine colony.—A slow liquefying colony, showing a peculiar folding. 
Gelatine stab,—A needle growth, beginning’to liquefy in one day, and about 
half liquefied in ten days; infundibuliform. 
Agar streak.—Filiform, thick, smooth, opaque, whitish, moist, moderately 
luxuriant. 
Fermentation tubes.—All three sugar bouillons are slightly acid, but there is 
no closed arm growth, and no gas. 
Bouillon.—A sediment and slight turbidity, but no pellicle. 
Milk.—Rendered alkaline, curdled in three days and subsequently digested. 
Potato.—Spreading, thick, mottled, wrinkled, white, luxuriant, with dis- 
colored potato. 
Grows at 20° and. 37°. Aerobic. 
Variety A.—Differs in the following points: No chains observed. Colony 
without the peculiar folding. Digestion of milk not noticeable. Growth on 
potato scanty and not wrinkled. 
Bact, lactis Gorinii n. 8. A non-acid, white, liquefying Bacterium. The 
original of this organism was sent from Italy by Gorini. Two very similar cul- 
tures were found by us, one in New York and one in Connecticut. The 
original culture had the following characters: 
Morphology.—Size, 1.54-2.54 x Iu. Rods with square ends. No chains, no 
spores. Gram stain positive. 
Gelatine colony.—A slow liquefier, producing a large pit with irregular mottled 
clusters of bacteria, 
Gelatine stab,—Begins to liquefy in two days and is 3{ complete in three 
weeks. Infundibuliform. 
Agar streak.—Spreading, raised, smooth, opaque, white, moist, luxuriant, 
viscous. 
Fermentation tubes.—Dextrose and saccharose are acid; lactose not acid. 
No closed arm growth; no gas. 
Bouillon.—A sediment, turbidity, and a pellicle. 
Milk.—Made strongly alkaline, curdled and completely digested at 20°. 
Potato,—Spreading, thick, smooth, opaque, moist, luxuriant; potato dis- 
colored. 
Grows well at 20° and 37°. Aerobic.
