60 STORRS AGRICULTURAL EXPERIMENT STATION. 
No. 69, °(Rare.) 
Morphology, size, .8u by 2m. 
Gelatin plate; a liquefying colony, with a nucleus and a broad, granular 
margin, or sometimes uniformly granular without the nucleus. 
Gelatin stab; a narrow funnel, which widens as it liquefies into a broad 
funnel, The liquid has a granular tinge at the surface, and is cloudy, with a 
slight granular sediment. 
Agar; rapid growth, spreading widely into a white, opaque layer, with 
irregular, glistening edge. 
Potato; white, or cream white, and semi-transparent. 
Milk, curdles in five to six days into a soft curd, which is alkaline. It then 
digests into a colorless liquid, with a bitter taste. Produces butter with a 
sharp, sour taste, but a thoroughly “/Aical butter aroma. 
GROUP IX. LIQUEFYING BACILLI WITH SPORES NO LARGER THAN 
THE ROD. 
-No. 207. Bacillus subtilis. 
Not an uncommon inhabitant of milk. 
° 
No. 177. Bacillus megatherium. 
This species has been found once or twice. It is easily recognized from its 
great size, 2.54, in diameter, and its spores of much less diameter. Its com- 
plete characters have not been studied here. 
No. 184. (Rare.) 2B. lactis V. (?) (Fligege.) 
Morphology; a large rod, with square ends forming long chains. 
Gelatin plate, liquefies rapidly. Under the surface appear opaque, rough 
gelatin colonies, with a fibrous rim. Colonies liquefy rapidly, spreading into a 
uniformly granular or fibrous colony, 2 cm. in size in two days. When the 
colonies are near together the fibers become twisted and look like anthrax 
colonies. 
Gelatin stab; needle growth abundant. There is a horizontal liquefaction, 
with a rough, white, wrinkled, tough shiz, looking like a mould. The skin 
later becomes somewhat yellow, and the gelatin-is finally completely liquefied, 
with a yellow scum. 
Agar, abundant, rough, whitish yellow skin, with an ieeulah edge. 
Potato, a very abundant growth, thick and dry, forming an alos! 2a 
white surface. 
Mitk; no curd appears, but the milk digests in one to two weeks into a 
translucent liquid, with a thick, folded scum on the surface. It is strongly 
alkaline. 
This appears to me to be quite similar to 2. lactis V. (Fligge). It differs, 
so far as can be determined from his description, only in its action on milk, 
which, in Fitigge’s organism, did not produce the folded skin on the surface of 
the digested milk.
