Report on the Bacteriology of Water. 3') 7 



Beumer (" Zur Aetiologie d. Typhus abdominalis," ' Deutsche 

 medicinische Wochenschrift,' 1887, No. 28) 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 had 

 occurred. 



A similar discovery of the bacillus was made by Brouardel and 

 Chauternesse ("Enquete sur les Causes de 1'Epidemie de Fievre 

 typhoide qui a regne a Clermont-Ferrand," ' Annales d'Hygiene 

 publique et de Medecine legale,' vol. xvii, 1887, pp. 385 403 ; also 

 ' Revue d'Hygiene,' vol. ix, p. 368) in the course of an investiga- 

 tion of an epidemic of typhoid which prevailed at Clermont-Ferrand, 

 and in which neighbouring places using the same water supply were 

 also involved. 



Finkelnburg (" Ueber einen Befund von Typhusbacillen im Brun- 

 nenwasser," ' Centraibl. f. Bakteriol.,' vol. ix, p. 301) states that he 

 isolated the typhoid bacillus from a well which had in all probability 

 been contaminated with typhoid dejecta. 



Henrijean (" Contribution a 1'Etude du Bole etiologique de 

 1'Eau potable dans les Epidemics de Typhus," 'Annales de Micro- 

 graphic,' vol. ii, p. 401) found typhoid bacilli in the drinking water of 

 a Belgian village during an epidemic of typhoid fever. 



Kamen (" Zum Nachweise der Typhusbacillen im Trinkwasser," 

 ' Centralbl. f . Bakteriol.,' vol. xi, p. 32) detected typhoid bacilli in 

 water supplying a Russian military garrison, amongst whom typhoid 

 fever had broken out. 



Pere ("Contribution a 1'Etude des Earix d'Alger," 'Annales de 

 I'lnstitut Pasteur,' vol. v, p. 79) states that he was able to isolate 

 the typhoid bacillus from drinking water in Algiers, where typhoid is 

 endemic, occurring every year during the months of August, Septem- 

 ber, and October. 



Martin states (" Presence du Bacille typhique dans les Eaux 

 d' Alimentation de la Ville de Bordeaux," ' Revue sanit. de la Pro- 

 vince,' 1891, No. 181, p. 93; 'Centralbl. f. Bakteriol, vol. xi, 1892, 

 p. 413) that the typhoid bacillus was found by Ponchet in the public 

 water supply of Bordeaux during an outbreak of typhoid in that 

 city. 



Fodor (" Die Beziehungen des Typhus zum Trinkwasser," ' Cen- 

 tralbl. f. Bakteriol.,' vol. xi, 1892, p. 121), in a paper read at the 

 International Hygienic Congress held in London in 1891, describes 

 an outbreak of typhoid fever at Budapest, during which he succeeded 

 in detecting the typhoid bacillus no less than five times in the public 

 water-supply. It was afterwards ascertained that the waste water 

 from a laundry attached to the hospital gained direct access to the 

 principal water main in the town.
