Show wi W iI broken in its Parts, or diffolv’d in its Texture bind it together again byits aftringent Quality; fo that tho’ it was before too thin and aquéous, it is now reducd to a proper Confiftence for Fermentation. Thus when Muft proves thin and watery, it will not ferment kindly, unlefs fome auftere or aftringent Ingredient, as Red Rofe Leaves, or the like, be added to it to thicken and improve its Confiftence, and at the fame time prevent the Air it contains from making too eafy an Efcape. 5 But when a Liquor is too auftere, or its Roughneds proves fo great, that it cannot ferment, the Addition ofafix’d Alkali, ina proper Quantity, will remove the Obftruction, andleave it at liberty to work. So likewifé when the Operationis prevented bytoo large a Proportion ofAcid in the Liuor, the Method is to throw Chalk, Crabs3ole Armoniac, or the like, into it; € too unctuous or oily, as is the Cafe : b Wines, Salt of Tartar is made The Subjects of the fourth and fifth Claffes viz.

Thus, in order to ferment Sugar, Treacle, or any common Syrup, we firft let down the Matter with Water, to the Confiftence above-mention’d; and then, if there be Occafion, put Yeaft to it to quicken the Fermentation, and makeit pro- ceed kindly. The Subjects of the fourth Clafs, viz. The prepard recent Juices, and {pontaneous Tears of Vegetables are fo far from requiring any Ferment, that it often proves very difficult to reftrain or check the Fermentation they naturallyfallinto ; efpeciallyif the Seafon be warm, and the Juices rich ; at moft, if the Weather fhould prove cold, they-need only be fet in a warm Place to make them work. The Subjects of the fifth Clafs, viz. The prepar’d or infpiffated Juices of Vegetables, require no Ferment at all in the Summer, and but a {mall Proportion in the Winter, to fet them on working ; lefs than an Ounce of Yeaft to twentyPints of prepar’d Liquor, will ufually fuffice for that Purpofe in the coldeft Seafon: But in hot Countries, or fultry Seafons, thefe prepar’d Juices, and efpecially Sugar, are, of themfelves, apt to fall into a too violent Fer- mentation ; which therefore ought to be abated by the contrary Means. All the vegetable Bodies of thefe feveral Claffes defign’d for Fermentation, and prepar’d for it in the foregoing manner, ought, toge- ther with their Ferments, to be committed to epard Fruits feldom ftand in Need of Casks of Oak already feafon’d or imbu’dwith anything to make them ferment, for they gethe fame kind of fermented Liquor, or fome nerally begin to work of their own accord ; but other confifting of fubtil and penetrating Parts : if the Weather fhould prove exceeding cold, Then thofé Casks or Veflels having their Bungor the Operation proceed but languidly, it may not be amifs to quicken it, by adding a {mall holes lightly cover’d with a thin or fingle Cloth, and being fet in a warm Place, the Liquor Proportion of a Ferment, as little Yeaft, the will ferment.
