This sample is practically clear and bright in appearance, neutral in reaction and free from metals apart from negligible traces of iron and manganeseo The water is very hard in character though not excessively so, and it contains no excess of salinity or mineral constituents in solutione It is of the highest standard of organic and bacterial purityo These results are consistent with a pure and wholesome water suitable for drinking and domestic purposes.](https://iiif.wellcomecollection.org/image/b29209675_0011.jp2/full/800%2C/0/default.jpg)
