REPORT.
Bacteriologically the water of the Vellore Central Jail is in much better order than on the last two
occasions. The fœcal germs present are fewer in number, less objectionable in kind, and there are fewer
varieties. In all these directions therefore there is improvement to record. It will be well if this can be
maintained or better, still farther improved upon. There is still room for it.
Chemically the water is never good but apart from its great hardness and high content of salts the water
of the General well is not very bad. The organic matter present is moderate in amount and of vegetable
origin. The water of the Kitchen well is worse in every chemical particular.
