    Very numerous—sixteen to twenty-four in number. 4. Agglutination reaction. 5. Sugar reactions (see below). 6. Very pathogenic. Animals hcemorrhagic diarrhoea. 7. Stain: {a) Original methyl violet or carbolic methylene blue. {b) Culture Gi'am and weak carbol-fuchsin. Morgan’s No. i bacillus, to prove: 1. Litmus milk gives alkaline reaction, but very slowly. (Distinguish from B. coli.) 2. Mannite or de.xtrin litmus bouillon both negative. (Distinguish from B. Gaertncr.) 3. No pi'oduction of acid on mannite, neutral- red agar plates. 4. Stain cover-slide for flagella. 5. Produces diarrhoea in rabbits fed on cultures. 6. Stain Gram and weak carbol-fuchsin. Indol reaction negative = B. typhosus, B. para- typhosus (a and b). Litmus milk : 1. Acid, no clot, no gas = 5. typhosus. 2. Acid to alkaline and gas-formation = A’, para- typhosiis, B. typhosus, to prove : ]. Hanging drop actively motile—much more so than B. coli communis or other allied organ- isms. Often shows long fllamentous forms. 2. Cover - slide : bacillus is longer and more slender than B. coli communis. Stain for
