52 STORRS AGRICULTURAL EXPERIMENT STATION. 
Milk.—Is curdled slowly at 35°, and becomes acid: At 20° no effect on milk 
is seen. 
NO. 19; 
Locality,—Cromwell, October, 1892. 
Morphology.—A short rod 2 y. by I p. with rounded ends. It never forms 
chains, has uniform stain and shows no spores. 
Motility.— 
Relation to Air.—WiAll not grow under mica. 
Temperature.—Will not grow at 35°. 
Colony on Gelatine.—A smooth, round surface colony with slow growth, which 
becomes after six days a lemon yellow colony about 44 mm. in diameter and 
sinks into a liquefying pit. 
Gelatine Stab.—Slight needle growth. A thin, opaque surface of a lemon 
yellow color, which becomes sunken in the middle into a pit. After a week the 
pit is quite deep, but the gelatine does not liquefy. 
A gar-Agar.—An abundant, smooth, spreading, lemon yellow growth. 
Potato.—An abundant, moist, lemon yellow growth. 
Boutllon.—A uniformly slightly cloudy liquid with a very slight sediment. 
Mitk.—I\s rendered slightly alkaline, but is not curdled. After two weeks’ 
growth at 20° the milk becomes partly transparent, showing that its casein has 
been peptonized. In six weeks milk becomes completely transparent and of a 
dark brown, almost red color. | 
No. 20. 
Locahty.—Cromwell creamery, October, 1892. 
Morphology.—A small bacillus 1-3 y. by .7 y. A uniform stain. No spores 
seen. Occasionally adhere in chains of three or four. 
Motilty,— 
Relation to Air.—Will grow under mica. 
Temperature.— Grows well at 35° and 20°. 
Colony on Gelatine.—A white bead spreading into a round surface colony 1 
mm. in diameter, sunken in the middle with a raised rim around the edge. 
Gelatine Stab.—Gas produced; slight needle growth and slight, dry surface 
growth. 
A gar-Agar.—Spreads diffusely in a thin, white layer showing branching marks 
radiating from the central streak. 
Potato.—Spreads diffusely into a watery mass with a yellow tinge. Later the 
growth thickens and the color may become a darker olive. 
Milk.—Curdles at 37°, but not at 20°. When curdled it is acid: 
Boutllon.—A uniformly cloudy liquid with a sediment. After three weeks a 
rather tenacious white scum appears. 
Nosrer, 
Locality,— Ellington creamery, November, 1892. . 
Morphology.—A slender rod 2 yp. by .8 uw. Frequently associated in long 
chains. No spores seen. 
Motihty.—Is motile. 
Relation to Air.—Will not grow under mica.
