isolate typhoid bacilli from the river Seine at Ivry at a

 where the water is abstracted for the supply of Paris 

 with drinking water. 



Beumer 1 was able to detect the typhoid bacillus in 

 a well-water used for drinking purposes in a country 

 place near Greifswald, where an outbreak of typhoid 

 fever had occurred. 



Brouardel and Chantemesse, 2 in the course of an 

 investigation which they conducted into the causes of 

 an epidemic of typhoid fever which prevailed at Cler- 

 mont-Ferrand, claims to have discovered the typhoid 

 baccillus in the water supplying that place as well as 

 other places in the neighbourhood which were affected 

 with the disease. 



Henrijean 3 found typhoid bacilli in the drinking 

 water supplying a village in Belgium during an epidemic 

 of typhoid fever. 



Kamen 4 detected typhoid bacilli in water supplying 

 a military garrison, amongst whom typhoid fever had 

 broken out. 



Loir 5 discovered the typhoid bacillus in river Seine 

 water which was being distributed to a portion of Paris 

 during the summer of 1887, in consequence of the 

 scarcity of the Yanne water, which yields the supply 

 under ordinary circumstances.
