466 L. Rogers — Relationship of the ivater-supply, water-logging [No. 4, 



Hooghly, so that the water-levels do not help in explaining the 

 difference. On the other hand, the dwellers near the river will mostly 

 drink river water, while those who live more inland are entirely 

 dependant on tank water. The other part of the South Barrackpore 

 Municipality which was examined lies to the east of the railw r ay opposite 

 North Barrackpore, and consists of the villages of Chandanpukuria 

 and Nona. The spleen-rate wns found to be 516, while the ground 

 water-level was 10 ft. 4 in. below r the surface in February, but had risen 

 to within 5 ft. during the rains of 1899, figures which are much more 

 favourable than those of Maniktolla and Chitpore-Cossipore, which 

 have the lowest spleen-rates. This, the most north-easternly Ward of 

 the South Barrackpore Municipality, is also dependant on tank water 

 for its drinking supply. The much lower spleen-rate, then, of the parts 

 near the river, as compared with those at a distance of two miles or 

 more from it, is again borne out by this Municipality, the figures of 

 which are giveu in the table below.

— This is a sms 



ill Municipalit\ r 



which 



lies on the east 



bank of the Hooghly between South and North Barrackpore, and is 

 bounded on the south by the Khardaha Khal, and on the north by the 

 Tittaghar Khal, and on the east by the Grand Trunk Road. It is 

 divided into four Wards numbered I. to IV. from north to south. Two 

 Mills in Wards II. and 111. supply a limited amount, of filtered water 

 more especially to the inhabitants of Ward II., but Wards I. and IV. on 

 either side of the other two driuk nearly entirely river and tank water. 

 Here, then, was a very good opportunity of putting to a crucial test 

 the question as to whether filtered water drinkers suffer less from enlarge- 

 ment of the spleen than do those who drink other kinds, so notes were 

 made regarding nearly all of the people examined in this Municipality 

 as to what water they usually drunk, whether filtered, Hooghly, or tank.
