Bacillus. 91 



patients in India, in every case, the same Bacilli that they 

 found in Egypt. But it was still undecided whether these 

 Bacilli did not belong to the regular parasites of the gut, 

 having made their way into the mucous membrane of the 

 intestine under the influence of the cholera disease. Some 

 of the Bacilli were, therefore, isolated from the intestinal 

 contents of the purest cholera cases and cultivated in 

 gelatine, so as to investigate their distinctions from other 

 Bacilli. In this way it was demonstrated that this kind of 

 Bacillus was present in all the choleraic evacuations ex- 

 amined, as well as in all the intestinal contents from persons 

 who had died of cholera. On the other hand, the bodies 

 of eight persons who had died of pneumonia, dysentery, 

 phthisis, and kidney-disease were examined, as well as the 

 bodies of several animals, and other substances abounding 

 in bacteria, but in none of these cases was the cholera 

 Bacillus found. It is also reported that the same organism 

 was discovered in water from a tank, which had been 

 suspected of being a source of the disease. 



Bacillus of Syphilis. 



Despite the strenuous efforts which have been made 

 to demonstrate the existence of a specific Bacillus of 

 syphilis, it must be admitted that the evidence is as yet 

 inconclusive. 



There are also described the Bacillus of the pneumo-enteritis of the 

 pig (Klein, Proc. Roy. Soc., xxvii. p. 101), which resembles .#. anthracis, 

 but differs in the cylindrical spores, which measure only '5 /j. in length ; 

 the Bacillus of malignant oedema (Koch) ; B. urea (Miquel) ; and a 

 Bacillus in a badger's liver (Eberth).
