Hippocrates, in his Trcatife de Acre, Aquis t$ Locis, fpeaks much in behalf of light Water.--— Herodotus relates, That among the Ancients, fome Nations drank a Water fo very light, that all Woods readily funk therein. And Mr. Soyle mentions fome Water brought out of Africa into England, which was fpecifically lighter than ours, by four Ounces in a Pint, i. e. by one third. See Waterpoise.
Tis efteem'd a good Quality in Water, to bear Soap, and

Nor does it diffblve terrene or earthy Bodies, but rather unites and confolidatcs them ; as We fee in Tyles, [£?c. See Earth.
After diflblving a Body, the Water unites and hardens to- gether jyith it ; and, if the Body be of the filing Kind,

In Agriculture and Gardening, Water is allow'd abfolute- ly neceflary to Vegetation ; whence Varro places it in the Number of the Divinities he invokes in his firliBook de Re Ruftica: Ftiam, fays he, precor Lympha, quoniamfine aqua munis mifera eji agricultura. See Watering.

Many Naturalilts have even maintain'd Water to be the Vegetable Matter, or the only proper Food of Plants ; but Rn Woodward has overturn'd that Opinion, and /hewn, that the Office of Witter in Vegetation, is only to be a Vehicle to a terreitrial Matter, whereof Vegetables are form'd ; and does not it felf make any Addition to 'em. — Ail Water, he
allows, contains more or lefs of this rcrreftrial Matter ; Spring fometime in a proper quantity'of Water ■ the Salts diflolvine and Rain-Water near an equal quantity, and Kiyet-Water will be extracted from the Oil, and imb'ib'd by the Water ■ more than cither of 'em.

Spirir of Wine, mix'd with Oil, makes one Bodv there- with ; but if you pour Water thereon, it will repel the Oil, and draw all the Spirit to it felf; nay, frequently, what the Spirit had diffolved in other Bodies, Water will feparate from 'em, by attenuating the Spirit, and letting the other the Water it contains. — Nor has any other Body the rower Matters precipitate.
