THE OBGANISM IS A BACILLUS. 

 THE GELATINE IS NOT LIQUEFIED. 

 THE ORGANISM IS NON-CHEOMOGBNIC. 

 THE COLONIES ARE BRANCHED. 



Bacterium Zopfli (Flilgge), from the intestmes of chicken ; an actively 

 motile bacillus, 2 to 5 /i long ; the colonies resemble those of 

 Bacillus figurans. 



Bacillus of mouse septicsemia (Koch's bacillus of hog erysipelas), 

 very minute bacilli, 1 ;* in length ; the motility is doubtful ; 

 the colonies are characteristic, forming a delicate, cloud-like, 

 radiating growth ; stains readily by Gram. 



Bacterium Ziirrianum (Adametz), from water ; short rods with pointed 

 ends, about 1 ^ in length ; stains more deeply at the extremities 

 than in the centre ; the colonies resemble clusters of grapes. 



Bacillus stolonatus, from water ; a short motile bacillus ; on agar the 

 colonies are characteristic, branching and rebranching from the 

 central growth. 



Bacillus multipediculus (Flilgge), from air and water; long, slender 

 bacilli, forming zoogloea masses ; the colonies send off long, 

 slender, segmented processes, resembling the legs or antennae of 

 an insect. 



Proteus lethalis (Babfes), from septicsemic lung ; short rods with 

 rounded ends, swollen in the centre; forms short, flexible 

 filaments ; stains by Gram ; is not killed by a temperature of 

 80° C. ; the colonies are slightly yellow. 



Proteus Zenkeri (Hauser), from putrefying animal matter; motile 

 baciUi, from 1 to 2 /* in length ; is without odour, and does not 

 liquefy blood serum ; colonies form central laminated masses, 

 giving off processes forming round colonies at their extremities. 



Proteus hominis capsulatus, baciUi varying in size ; rather thicker 

 than the anthrax bacillus ; irregular in outline, non-motile 

 and capsuled; stains by Gram; the growth in gelatine stick 

 cultures resembles that of Friedlander's bacillus.
