In regard to the bacterial content the figures compare somewhat unfavourably with the previous sample, but the interval of time in transit of this present sample is much longer and might account for most, if not all, of the increase in numbers. There are no excremental organisms found in the quantities examined and the chemical figures are approximately much the same as in the previous sample. From consideration of the combined results the water is safe for drinking purposes.
