The Special Committee appointed to enquire into the quality of Madras City
water-supply called for the analysis of a large number of samples. The results
of these analyses will be found in the report presented by the committee.
Routine analysis.-Towards the end of the year the routine analyses of piped
supplies and of jail supplies were resumed. To such supplies, at the instance of
the Pilgrim Commission, the water supplies at important railway junctions,
where large aggregations of people take place, were added.
