    possible, indicated the rapidity of filtration and the ease or difficulty with which they can be cleansed and their output renewed in the case of the respective filters. The reliability of the latter points may no doubt vary under difierent condi- tions, and we have no doubt that one filter may be better adapted for some conditions than for others. We have not, however, attempted to do more than to supply the data upon which water engineers and those interested in this question of water filtration may determine the form of filter best suited for their purpose. The conditions which obtain in actual practice are no doubt in many respects difi'erent from those which have come into operation in our experiments. Only experience can determine which of the filters reported upon are best adapted for domestic purposes; and should none of those at present on the market meet these require- ments we have no doubt that the demand for such an article will in due course lead to the want being supplied.
