DESCRIPTION OF SPECIES. 



colonies, and on the surface a 

 greyish film. 



On agar they produce a greyish- 

 white growth. 



On potato a transparent whitish 

 film. 



They are fatal to rabbits, guinea- 

 pigs and small birds. 



They are probably identical with 

 Bacillus septicaemias haemorrhagicae. 



They were isolated from pus in 

 a case of tetanus. 



They were isolated from deep-sea 

 dredgings. 



Bacillus of Colomiatti. Minute 

 rods. Spore-formation occurs at 

 the ends of the rods. They can 

 be cultivated at 37 C. 



They form a thin film on agar 

 and on blood serum. 



They were isolated in cases of 

 conjunctivitis. 



Bacillus of Fulles, No. I. Rods 

 1 to 1'2 /u, in length, - 6 p in width. 



Colonies circular, granular, yel- 

 lowish-brown. 



On the surface of gelatine they 

 produce a thin film, and in broth 

 turbidity and flocculi. 



On potato the growth is yel- 

 lowish. 



No. II. Very short rods. 



Colonies circular, granular, yel- 

 lowish. 



In the depth of gelatine the 

 growth resembles Friedlander's 

 pneumococcus. 



On potato the growth is yellowish. 



They were isolated from earth. 



Bacillus of Guillebeau. No. I. 

 Short rods 1 to 2 p in length, 1 /n 

 in width. 



Colonies spherical, granular. 



In gelatine the bacilli produce a 

 growth in the track of the needle 

 and a white patch on the surface. 



On agar the growth is white, and 

 on potato yellowish, viscid, and con- 

 taining gas bubbles. 



They coagulate milk. 



No. II. Rods resembling the 

 above described but distinguished 

 by the production of viscid colonies 

 and, extremely slowly, of liquefac- 

 tion in the jelly. 



No. III. Rods also resembling the 

 above mentioned, but colonies are 



adherent to the jelly and coarsely 

 granular. 



Milk and other liquid culture 

 media are rendered extremely vis- 

 cid. 



Bacillus of Letzerich. Rods 

 sometimes bent, and filaments. 



They rapidly liquefy gelatine. 



They produce purulent peritonitis 

 and death in rabbits. 



They were isolated from urine. 



Bacillus of Martinez ( Stern - 

 berg). Short rods 1 to 1-2 \JL in 

 length and -5 to '8 p. in width ; 

 non-motile. 



Colonies circular and translucent, 

 with a central, nipple-like projec- 

 tion, and the surface covered with 

 mosaic markings. 



In the depth of gelatine the 

 growth consists of large spherical 

 translucent colonies in the track of 

 the needle, and a thin, translucent, 

 scanty growth upon the surface. 



They were isolated from the liver 

 in a fatal case of yellow fever. 



Bacillus 9f Nocard. (Vide Strep- 

 tothrix farcinica.) 



Bacillus of Okada. Short rods 

 rather thicker than the bacilli of 

 mouse-septicaemia, singly, in pairs 

 and in filaments. Spore-formation 

 not observed. 



Colonies granular and brownish. 



Inoculated in the depth of gelatine 

 they form a white filament, and on 

 the surface a milk-white patch. 



Inoculated on agar the growth 

 spreads over the surface forming a 

 milk-white layer. 



In broth they produce cloudiness 

 and a layer floating on the surface. 



They do not grow on potato. 



Cultures produce death in mice, 

 guinea-pigs and rabbits in twenty 

 hours. 



They were isolated from dust. 



Bacillus of Roth. No. 1 and 

 No. 2. Rods. 



Two varieties were isolated from 

 old rags. They appear to be 

 varieties of Bacillus coli communis. 



Bacillus of Sattler. 2 to 4-5 p 

 long and '58 p thick. 



They can be cultivated on nutrient 

 gelatine and blood serum.
