THE ORGANISM IS A BACILLUS. 



THE GELATINE IS LIQUEFIED. 



THE OEGANISM IS NON-MOTILE AND CHEOMOGENIC. 



THE COLONIES ARE GREEN OR YELLOW. 



Bacillus graveolens, from the scales of epidermis between the toes ; 

 baoiUi "8 /* in length, almost the same in breadth, resembling 

 micrococci ; the cultures have a disagreeable odour ; blood

Bacillus CUticularis (Tils), from water; bacilli 2 to 3 /t long, 0-5 /i 

 broad, soruetimes in filaments ; motility doubtful, some of the 

 shorter rods appearing to have slight movement. 



Bacillus lactis erythrogenes (Hueppe), baoiUus of red milk, also 

 found in the faeces of a sucking child ; short baciUi, 1 to 1'4 /j. in 

 length ; the colonies are first yellow, becoming pink, and give 

 off a very offensive smell. 



Bacillus smaragdinus foetidus, from nasal secretion in ozena ; small, 

 slender, shghtly-curved bacUU, half the size of Bacillus tuber-

 the whole of the medium becomes emerald green, later on 

 becoming brown. 



Bacillus buccalis minutus (BacUlus G of Vignal), short bacilli as 

 broad as long ; from healthy human sahva ; the two ends stain
