 Soi^e: the Water-supply. 



Having, then, ascertained that there must be some local condition in Delhi tending 

 to produce " abscess and ulcer," and a condition to which the native troops are more 

 exposed than the Europeans, we have next to endeavour to ascertain to what extent 

 these statistics indicate the occurrence of the special form of disease known as " Delhi 

 sore " among the troops, and whether it occurs more among the native than the European 

 troops. 



Although the existence of a peculiar form of sore in Delhi has been long well 

 known, it was, as already mentioned, only after the mutiny that the occurrence of the 

 disease among the troops stationed there attracted any special attention. Previous to 

 that period the greater part of the troops in the station were located in the old cantonment 

 at some distance from the city, and it is a well ascertained fact that there is but a 

 very slight tendency to the development of the affection in people living there as 

 compared with those within the city walls. The troops occupied the interior of the city 

 from the latter part of 1857, and from that date the prevalence of the disease among
