    been proved by the two lafl: mentioned experi- ments, to contain a marine acid, and by fome of the previous ones, that this cannot exift in a fepe- rate Hate; therefore it muft be united either with an earth, or an alkali, and as a cretacious alkali will be iliewn to be prefent in the water, it is evi- dent that it muft be joined with the latter ; fince alkalies have a greater attraction for acids, than earths have. VI. A CRETACIOUS ALKALI, whereby, after the water has been boiled, it renders the infufion of lark-fpur green, and effervefces with vitriolic acid; this may alfo be the caufewhy lime-water- is (till precipitated by it. Here the cretacious acid quits the alkali, to unite with its more at- tracting lime, forming therewith, as abovemen- tioned, an infoluble compound. The reafon why the water did not change the infufion of lark- fpur, before it had been boiled, muft be owing to the alkali's being fuperfaturated with the creta- cious acid, in which cafe, as I proved by an expe- riment made for that purpofe, it may exift in a confiderable quantity in a water, without chang- ing vegetable blues. VII. A slight impregnation of SULPHUR, thereby darkening the nitrated filver; this is what might reafonably be expected, as within about four miles there is a proper flrong fcented fulphu- rious fpring.
