DETECTION OF PATHOGENIC BACTERIA IN WATER 259

 Canalbacillus (Eintaro Mori) (see p. 429). The two latter 

 species were new, whilst the first was the well-known 

 bacillus of mouse septicaemia previously discovered by 

 Koch. 



Jaeger 1 states that he successfully isolated a bacillus 

 from the river Blau, a small, highly polluted tributary 

 of the Danube, which was pathogenic to white mice. 

 This bacillus he calls Proteus fluorescens (see p. 421), 

 and asserts that he discovered it also >in the car- 

 cases of birds which had died of a mysterious disease 

 at a small village through which the Blau flows, and 

 where the practice was to throw such carcases into the 

 stream as the readiest means of getting rid of them. 

 Jaeger attributes an outbreak of jaundice-fever (Weyl's 

 disease) which occurred in a military station situated 

 on the stream in question to the soldiers having become 

 infected with this bacillus whilst bathing in its waters. 



Lortet 2 alleges that he was able to isolate the 

 tetanus bacillus (see p. 423) from mud obtained from 

 the bottom of the Dead Sea. 



G. Eoux 3 also states that he has found the tetanus 

 bacillus in large numbers in the sediment of the filter- 

 beds belonging to the waterworks supplying Lyon with 

 the river Ehone water. Miquel has also found this 

 bacillus in the rivers Seine and Marne. 



Lortet 4 has also examined the mud taken from 

 the bottom of the Lake of Geneva. The water in the 

 neighbourhood of the spot from which the sample was
