REPORT.
The water of the Bellary Central Jail is as bad as usual and that is saying a good deal. The only trace
of comfort that we can extract from these examinations to date is that the water does not appear to be liable
to recent excremental pollution. That it has been so polluted antecedently the high figures for chlorine and
oxidised nitrogen vouch for. What organic matter is left unoxidised is of animal origin. As pointed out
before the water is exceedingly hard. Under such circumstances we usually find a high total count of germs
and fœcal organisms largely in evidence. This sample is no exception, though it must be admitted that the
fœcal germs are in themselves unobjectionable.

REPORT.
With regard to these samples there is very little to say. There is nothing to take away from or to add to
what has been said on the previous occasions. The only grain of comfort that can be extracted from the
results is that the water is and has consistently been free from evidence of recent and dangerous pollution,
The water is of a very unsatisfactory type for drinking purposes. .As before the water of the Hospital Well
is a shade less bad than that of the Kitchen Well.

REPORT.
In December of last year it was possible to make the reservation that the Vellore Jail water-supply was
not in a condition to cause epidemic disease. This reservation must now be withdrawn. With the kitchen
well water showing the presence of B. Coli Communis and vibrios there is no possible doubt as to its poten
-tiality to cause disease. The water of both wells is quite unfit for a drinking water-supply.

REPORT.
This water always shows a high total count, but a slight improvement as to the number of fœcal germs
has been maintained. These latter however are of the more resistant kinds and point to the pollution of
the water being of antecedent date. This is borne out by the high figure for oxidised nitrogen, but this time
the figures for ammoniacal and albuminoid are also too high. Taking this along with the great hardness
and salinity the water cannot be considered at all good.

REPORT.
Unfortunately there is nothing new to report as to the water of the Kitchen well, any change could
hardly help being one for the better, but there is. none.
Unfortunately again, the up till this time, slightly less bad water of the Hospital well shows the
presence of vibrios, which altogether neutralises what advantage it may be said to have had. Both supplies
are entirely unsatisfactory.
