REPORT.
The water of the Pump well was not examined at this season last year so the most useful comparison
cannot be made, but it is worse than it was in May last. The deterioration is shown in the largely increased
total count, in the increase of fœtal germs and in these latter belonging to different varieties and classes.
In this last respect however the condition is not very bad as varieties and classes are limited to two.
Chemically the water shows the usual high figure for exidised. nitrogen, but is in other respects slightly
better than it was in May. Chemically it is quite a fair water.
Sample II.—isa l s o w o r s e b a c t e r i o l o g i c a l l y t h a n i t w a s o n t h e l a s t e x a m i n a t i o n , a n d a b o u t i n t h e s a m e
proportion. As it was worse than. Sample I to begin with, its state now is far from satisfactory. One
hundred fœtal germs to the cc. is far too many even though only fairly resistant types are represented.
Chemically the water is very like that of the Pump well, so is satisfactory enough.
