This Gentleman, in his very valuable ex- perimental inquiry into the nature and qua- lities of Cheltenham Water, p. 42, con- cludes, “ from the preceeding experiments, a Gallon of the Water, wine meafure, appears to contain the fubfequent principles, nearly in the following proportions ; Native Glauber Salt, with a portion of Epfom Salt, one ounce; Sea Salt, five grains; Iron combined with fixed Air, five grains ; Magnefia com- bined with fixed Air, twenty-five grains; Calcarious earth, or Selenite, forty grains; fixed Air, combined with phlogiflicated Air, twenty-four ounce meafures. To thefe may, perhaps, be added a fmall proportion of He- patic Gas, or Hepar Sulphuris converted into Vapour by the feparation of its phlogifton.” . . 1 , By this ingenious work, it appears, and, is fufficiently known to all who frequent Chel- tenham, that the Iron is very foon precipi- tated from the Water, after it is drawn from the Pump ; and, in a fhort time it cannot be made to affume a purple colour, by the ad- dition of aftringents.](https://iiif.wellcomecollection.org/image/b21522996_0018.jp2/full/800%2C/0/default.jpg)
