THE CLASSIFICATION OF BACTERIA 197 



208. Bact. Mansfieldii 



B. No. 18 Conn: I.e., 1893, 51. 



Morphology. Bacilli 1.4-2.0 /n, in twos and threes. 



Gelatin colonies. Round, white, punctiform, i mm., spreading only slightly. 



Gelatin stab. Surface growth white, spreading, rather dry. 



Agar slant. Growth white, rather limited to spreading. 



Potato. Growth thick, spreading, mottled ; somewhat raised in mounds, 



becoming brown and more uniform. 

 Bouillon. Turbid, with a sediment and slight pellicle. 

 Habitat. Milk from Mansfield, Conn. 



209. Bact. Schottelii (Trevisan) 



Darmbacillus Schottelius : Der Rotlauf der Schweine, Wiesbaden, 1885. 

 B. coprogenes-fatidus : Fliigge, Die Mikroorganismen, 1886. 

 B. Schottelii Trevisan : Genera, 1889, 17. 



Morphology. Bacilli shorter than B. subtilis. Spore germination polar. 

 Gelatin colonies. Deep: compact, pale yellowish. Surface: gray, trans- 

 lucent, spreading ; strong putrefactive odor. 

 Potato. Growth thick, gray. Non-pathogenic. 

 Habitat. Isolated from the intestinal contents of swine. 



210. Bact. subtiliforme (Schroter) 



Bacillus I Bienstock: Zeit. f. klin. Med., VIII, 1884, 1-2. 



B. subtiliformis Schroter : Pilz Schles., 1886, 160. 



B. mesentericvs Trevisan : Genera, 1889, 115. 



B.fcscalis 1 Kruse: Fliigge, Die Mikroorganismen, 1896, 215. 



Morphology. Like B. subtilis. Gelatin colonies have the form of a mesen- 



terium. 

 Habitat. Faeces. 



211. Bact. simile (Schroter) 



Bacillus II Bienstock : l.c. 



B. similis Schroter : l.c. 



B. coprocinus Trevisan : Genera, 1889, 15. 



B.fcecalis II Kruse: Fliigge, Die Mikroorganismen, 1896, 213. 



Morphology. Like the preceding. 



Gelatin colonies. White, glistening, smooth, becoming uneven, with lobular 



outgrowths. 

 Habitat. Faeces.
