SPECIES DESCRIBED BY VARIOUS WRITERS. 2OJ 



Bacillus septicus, Klein. * Rods varying in 

 size, non-motile. They form threads or leptothrix 

 filaments, and are rounded at the ends. They are 

 anaerobic, and form spores independently of access 

 of air. In a nourishing fluid they are overcome 

 by the presence of micrococci, Bacterium termo or 

 Bacillus subtilis. They occur in the soil, in putrid 

 blood, and many putrid albuminous fluids, and 

 occasionally in the blood-vessels of man and 

 animals after death. 



Bacillus of septicaemia of man, Klein. f 

 Rods singly or in chains, i 2-5 //, long, -3 -5 //, 

 wide, which were observed in the blood-vessels of 

 the swollen lymphatic glands, forming continuous 

 masses in the capillaries and the minute veins. 



Bacillus of gangrenous septicaemia, Ar- 

 loing and Chauveau. Short rods, possessing 

 spores, were observed around wounds in gangre- 

 nous septicaemia, and considered to be the cause 

 of the gangrene. 



Bacillus of ulcerative stomatitis in the 

 calf, Lingard and Batt. Rods 4 p, 8 /*, or more 

 in length ; i p, in width. Spores are frequently 

 present. Injected into the rabbit or mouse they 

 produce a fatal result. They were observed in 

 ulcerations on the tongue and mucous membrane 

 of the mouth of calves.
