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 agar 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 septicaemia. Proteus sulfureus (Lin- denborn).—Rods '8 ;u. in width, varying in length, and long filaments. They correspend in mor- phology and cultures with Proteus vulgaris.
