(7) They turn a Solution of Subli¬ mate in Water, yellow, or red; Syrup of Vio¬ lets, or red Rofes, green, See. 61. Volatile, alkaline, Salts appear to diffei but little from the fix’d ; except in thofe Pro¬ perties which depend upon their Volatility; foi thefe alfo are cauftick, and fiery to the Tafte ; but, on account of their volatility, brifkly ftrike. and fhake, the Nerves of theNofe; being fpon- tanecufly volatile, and flying away in the oper Air, and in Diftillation, rifing fooner than Spi¬ rit of Wine. Thefe alfo regenerate Nitre, and Sea-Salt, from their Spirits; tho’ the Salts thus regenerated are femi-volatile, or much more vo¬ latile than the natural ; being in this refped like Sal-ammoniac. And laftly, they produce the lame Changes of Colour, upon Mixture, with other Things, as the fix’d. 62. Under this Head of Alkalies therefore, our Experiments mult be directed to difeover, whether an earthy, a fix’d, faline, or volatile, Alkali, be contain’d in a Mineral Water. And firft, if a volatile Alkali fhou’d be contain’d therein, we fee it may be reafonably expected that this fhou’d manifeft itfelf by its Odour, by Additions, or by Diftillation. The Odour of a volatile alkaline Salt, if anyfuchbe contain’d in a Water, may be perceived by immediately ap¬ plying the Noftrils thereto ; efpecially as frelh taken up from the Well; for if a very few Grains of the volatile Salt of Hartfhorn, or a few Drops of the Spirit of Hartlhorn, or Spirit of
