REPORT ON THE WORKING OF THE KING INSTITUTE, GUINDY

Coimbatore Central Jail.

W. S. No. 75 of 1922.

     The samples from the æromotor well, Garden well No.1 and factory well contain
vibrios.

     The sample from the annexe well is by far the best of the series and also of the wells
in the Coimbatore district so far examined at this Institute. It is much less hard, contains
only about a third of the total solids present normally in other wells, and the major portion
of the hardness is temporary and removeable. If this supply could be utilized for the whole
jail, it would mark very definite improvement as far as the water-supply of the jail is con-
cerned. The samples from the æromotor and garden wells particularly show a considerable
excess of organic matter both in an oxidised and unoxidised condition.

     Seeing that the condition of the water-supply is far from satisfactory, it appears impera-
tive that a system of efficient chlorination or boiling should be inaugurated.
