XI] BACILLI : SPECIFICALLY PATHOGENIC 233 



and spleen. Bacilli were found in the blood and exuda- 

 tions of these animals. On cultivating blood and lung 

 juice from the above case a crop of bacilli was produced 

 which on inoculation proved very poisonous in the same 

 way as in the previous cases. 



7. Bacillus enteritidis of Gartner} — This microbe was 

 found in the flesh of a cow that had been killed after ailing 

 with diarrhoea ; and the bacillus was also found in the 

 spleen of a man who died twelve hours after eating of the 

 above beef The morphological and cultural characters — 

 as far as investigated — coincide with those of bacillus coli ; 

 on rodents the cultures proved virulent on mice after 

 feeding, and on rabbits and guinea-pigs after subcuta- 

 neous injection. It seems to me quite probable that this is 

 the same microbe that I mentioned sub (5) as the beef-pie 

 (Portsmouth) bacillus. 



8. Of the same nature, i.e. allied morphologically and 

 culturally to a variety of bacillus coli, is the bacillus de- 

 scribed by H. Laser {^Centralblatt f. Baderiologie vnd 

 Parasit., xiii. Band, No. 7, p. 217) as a "gas-forming aerobic 

 bacillus," and which was met with in and cultivated from 

 the lung and liver of a young calf that had died, with several 

 others, from so'me unknown malady. The characters of the 

 microbe in microscopic specimens and in culture on the 

 various media show that it belongs to the colon group. 

 The cultures possess on subcutaneous injection into rodents 

 a moderate degree of virulence and produce in a small 

 percentage of them septicemic infection. 



9. A bacillus possessed of the power, to a considerable 

 degree, of forming gas has been obtained from the dead body, 

 and described by Welch and Nutall under the name of
