THE OEGANISM IS A BACILLUS. 



THE GELATINE IS LIQUEFIED. 



THE OBGANISM IS MOTILE. 



THE COLONIES AEE GEEEN OE YELLOW. 



Bacillus fluorescens liquefaciens, from water ; small bacilli, in pairs ; 



an air-bubble forms on the surface of the liquefied gelatine in 



stick cultures. 

 Bacillus melochloros (von Schrotter), from air ; characterized by its 



rapid growth, grayish-white colonies, appearing in four hours, 



becoming yellow on the second day ; slender rods with round 



ends ; actively motile (rare). 

 Bacillus aQLuatilis (Frankland), from water ; short rods forming 



filaments ; feebly motile ; pale yellow colonies. 

 Bacillus radiatus aquatilis (Zimmerman), from Chemnitz water; 



radiate colonies, having fine filamentous offshoots. 

 Bacillus ochraceus (Zimmerman), from Chemnitz water. 

 Bacillus pyocyaneus (Gessard), from green pus ; slender rods with 



rounded ends provided with a flagellum ; the fluorescent green 



tint is developed in about two days, and gradually changes to 



olive green. 

 Bacillus citreus cadaverus (Strassmann), from the blood of a cadaver 



fifty hours after death ; oval bacilli, 0*9 f- long, in chains. 

 Bacillus termo of Vignal, from healthy salivary secretion; bacilli 



1 to 2yu.long, constricted in the centre, resembling diplococci ; 



actively motile ; liquefies blood serum ; has a putrefactive odour. 

 Bacillus viscosus, from water ; resembles exactly Bacillus fluorescens 



liquefaciens. 

 Ascobacillus citreus (Unna and Tommasoli), from the skin in a case 



of seborrhoeic eczema ; small motile bacilli 1 /t long ; the growth 



on potato resembles the tracing on a vine-leaf. 

 Bacillus scarlatinas (Klein), from scarlet fever ; said to be identical 



with Klein's Streptococcus scarlatinse ; inoculation experiments 



gave negative results ; a small bacillus ; motility unknown.
