54 STORRS AGRICULTURAL EXPERIMENT STATION. 

Division B. 
Bacilh not rendering milk acid, 
No. 126. (Rare.) 
Morphology; a bacillus, size, .74 by 1.2m. 
Gelatin plate; an opaque bead, 1 mm. in diameter, slightly scolloped edge. 
Very white, opaque. ae 
Gelatin stab, typical nail growth. Not characteristic. * 
Agar, thick, white and abundant. ‘The agar occasionally tinged green or 
yellow. 
Potato, a yellowish or dirty white growth. Not characteristic. 
Milk, no effect. Butter made from cream ripened with this organism has a 
cheesy aroma and taste. 
No. 66. (Common.) 
Agrees with No. 126, except that the milk is rendered slightly alkaline and 
the cheesy taste does not appear in the butter. Butter on the other hand de- 
velops an excellent nutty flavor of the highest quality. 
Possibly these two organisms should be classified with the fluorescent, inas- 
much as they occasionally render the agar slightly green. 
No. 84. (Common.) m 
Morphology, size, .6u by .8u to 1.24. Occasionally six or eight unite together, 
but no long chains, 
Gelatin plate; a rounded bead, with a smooth edge, finely granular and with a 
dark center. It spreads over the surface as a dry, thin growth, 2 mm. in 
diameter. 
Gelatin stab, needle growth abundant. Surface growth dry, irregular and 
glistening. 
Agar, widely diffused growth, branching irregularly and lobate. * Yellow 
color. 
Potato, growth thin and of a yellowish or brownish or even orange color. 
Milk, no effect upon milk, cream or butter. 
No. 198. (Common.) &. communis lactis IJ. 
Morphology, size, .84 by tu. Forms short chains in bouillon. 
Gelatin plate, colony of the B. coli type. Surface colony spreads into a 
white, bluish growth, I.5 mm. in diameter. They are slightly yellow under 
the microscope, and may have a somewhat raised center. The colony is moist 
and glistening. 
Gelatin stab; abundant needle growth, with a thin, slightly spreading, white, 
dry, surface growth. 
Agar, not characteristic. 
Potato, a slight lemon yellow tinge, but not characteristic. No effect upon 
milk or cream, 
Differs from No, 84 chiefly in the form of the gelatin colony, Probably the 
same as No. 26, Previously described. (Storrs Sta. Rep., 1893.)
