Bacillus gasoformans (or gasbildender), from water; a very active 

 small baoUluB ; liquefles the gelatine, forming bubbles of gas. 



Bacillus liodermos, from milk ; resembles Bacillus mesentericus

Bacillus inflatus (Koch), from air; bacilli 4 to 5 /u long, sometimes 

 in filaments, showing two large spores in each rod (rare). 



Bacillus lactis albus, from mUk ; bacilli 3 /i long, in long filaments ;

 win not stain by Gram ; a gas-bubble is formed during lique-

 organs of a boy who died from septicaemia, following gangrene 

 of the skin, etc. ; oval or rod-shaped bacilli with round ends ; a

 four days after death ; bacilli 2 to 3 /n long. 



Bacillus venenosus licLuefaciens (Vaughan), from water ; bacUli 

 with rounded ends ; the gelatine liquefies very slowly.

 rounded ends ; solitary, in pairs or chains ; a gas-bubble is 

 formed in gelatine stick cultures. 



Proteus septicus (Babes), from the intestinal canal in a case of septi- 

 CEemia ; curved motile rods or filaments, often in chains ; lique- 

 fies blood serum ; cultures have a very offensive odour. 



Proteus sulfureus, from water ; resembles Proteus vulgaris. 



TTrobacillus Pasteuri (Miquel), from decomposing urine; baoUli 4 to 

 6 Ai long, generally in pairs ; wiU only grow on nutrient gela- 

 tine when alkaHne, or when urea is added, forms spherical 

 spores at one extremity of the rod.

 2 to 10 /t long.
