present in the blood and exudations of the animal. 

 They occurred in the blood and juices, and espe- 

 cially in the glomeruli of the kidneys, of several 

 fatal cases of choleraic diarrhoea. 



Bacillus pyogenes fcetidus, Passet. Small 

 rods, with rounded ends of about 1*45 p, in length, 

 and '58 fj. in width ; often in twos, or linked 

 together in chains. They are motile, and spore- 

 formation occurs. When cultivated in nutrient 

 gelatine, a greyish, veil-like growth forms on the 

 surface. In plate cultivations white points appear 

 after twenty-four hours, which develop into greyish 

 spots, and these enlarging coalesce into a layer. 

 In nutrient agar-agar the cultivation resembles the 

 growth on gelatine. On blood serum a moderately 

 thick greyish-white streak develops, and on steril- 

 ised potato an abundant, shining, brownish culture. 

 From all these media a putrid odour emanates, but 

 no smell is detected from a cultivation in milk. 

 Inoculated into mice and guinea-pigs abscesses 

 are produced or death from septicaemia results. 

 They were isolated from putrid pus. 



Bacillus in septicaemia of man, Klein.* 

 Rods singly or in chains, i 2*5 p long, -3 '5 p 

 wide, which were observed in the blood-vessels of 

 the swollen lymphatic glands. They are possibly 

 identical with the following: 



Bacillus in gangrenous septicaemia, Ar- 

 loing and Chauveau. Short rods, possessing
