The effects of the full-bodied wines are muchmore durable than those of the thinner; all sweet wines/as Canary,abound with a glutinous nutritious substance; whilst the others are notnutrimeulal, or only accidentally so by strengthening the organs em-ployed in digestion : sweet wines in genera] do not pass off' freely byin ine, and heat the constitution more than an equal quantity of anyother, though containing foil as much spirit: red port, and most ofthe red wines, have an astringent quality, by which they strengthenthe tone of the stomach and intestines, and thus prove serviceable forrestraining immoderate secretions : those which are of an acid nature,as Rhenish, pass freely by the kidneys, and gently loosen the belly:it is supposed that these last exasperate, or occasion gouty and calculousdisorders, and that new wines of every kind have this effect.
