561

 Islands on the Sukface of Gelatine, x 285

Proteus miraMlis.— Cocci -4/1 

 to '9 fi. They occur singly and in 

 zoogloea, and sometimes in tetrads, 

 pairs, chains, or as short rods in 

 twos resembling Bacterium termo — 



concentric circles, which in time 

 liquefies the medium. Similar 

 movements are observed in capsule- 

 cultivations as in Proteus vulgaris. 

 They were isolated from 

 putrid meat infusion. 



Proteus septicus 

 (Babes). — Eods -4 /i in 

 width, and filamentous 

 forms. 



Colonies rapidly liquefy 

 _.,^^ the gelatine. 



Inoculated in the depth 

 of gelatine the bacilli form 

 a turbid funnel, or com- 

 pletely liquefy the gelatine 

 in twenty-four hours. 



On aga;r the growth is 

 reticulated. 



On potato brownish- 

 white. 



Cultures have an un- 

 pleasant odour. 



They are pathogenic in 

 mice. 



They were isolated from 

 the organs in a case of 

 human septicemia. 



Proteus sulfureus (Lin- 

 denborn). — Rods '8 ft in 

 width, varying in length, 

 and long filaments. 



They correspend in mor- 

 phology and cultures with 

 Proteus vulgaris. 



They produce sulphuretted hy- 

 drogen in cultures. 



They were isolated from water. 

 Proteus vulgaris (Hauser).—

in fact, in all conceivable transition 

 forms. 



Cultivated on nutrient gelatine 

 they form a thick whitish layer in 



Rods varying in size ; some mea- 

 sure 4 ^ in length, and are almost 

 as broad as long, and others vary 

 from "94 to 1'25 /i long and '42 to
