"Water 3 oz. The following preparation, how- ever,appears to be more simple, and is equally efficacious : it was first published in the " Bihliotheque Phijsico-economlque,'' for 179^^ by M. LiiDiCKE ; who has employed it with great success for painting ceilings, gates, doors, and even furniture. He direfts fresh curds to be bruised in an earthen pan, or in a mortar ; after which they must be mixed with an equal portion of slacked lime : the result will be a white fluid, that may be applied with as much facility as varnish ; but it will be necessary to employ such mixture on the same day, as it dries very speedily, and is apt to become too thick, if it be kept 24 hours. — He observes that Arme- nian bole, ochre, and all pigments that are miscible with lime, may be incorporated in various propor- tions, according to the colour to be communicated ; but some caution is necessary, in making such addi- tion, to use the smallest possible quantity of water ; as the painting will otherwise be less durable. When two coats of this paint have been applied, it may be po- lished with a piece of woollen cloth, or other proper substance ; in consequence of which, it will become as bright as any varnish : and, if the ceiling, &c. be exposed to moisture, it should be coated with the whites of eggs ; by which expedient it wiU become as durable SA oil-painting. The principal ad-* PEA [445 vantages, derived from the use of this substitute, consist in its cheap- ness, and the facility with which the two coats may be applied, and polished j one day being sufficient for both operations. Hence, it de- serves the attention of those whose lungs cannot support the disagree- able smell arising from oil-paint; and who are not disposed to en- courage the extravagant charges of house-painters. PARSNEP.— This fibrous root possess ng a peculiar sweetness. Prof. Hehmbstaedt was induced to make various experiments, with the view of extracting sugar, ije caused a parcel of such roots, weighing iWlbs. to be pounded ia a stone mortar, with the additioa of a little cold water J after which, the juice was expressed, the resi- duum washed in pure water, and likewise submitted to the at^ion of a press : the result was a turbid, sweet liquor. After standing in a cool place for a few days, till it be- came clear, and evaporating it over a moderate fire. Prof. H. obtained 5jlbs. of an agreeable syrup. PEAT.— In the igth vol. of the the Encouragement of J its," 8cc» we meet with a description of aa implement contrived by Thowas EccLESTON, Esq, of Scaresbrick- hall, Lancashire. . It is denomi- nated a Peat-borer, and is designed for draining boggy land : as its ap- jilication has been attended with uncommon success, we have given an engraved ngure representing its construction.
