Oil of Sweet Almonds made by Expression.
Take new Almonds that are fat and very dry, without their Shells, and having shaken 'em in a somewhat thick Sieve, to cause the Dust to fall off; let 'em be put into hot Water till their Skins become tender, so that they may be separated by squeezing 'em with the Fingers: Afterward having taken off the Skin, they must be wip'd with a white Linnen-Cloth, and spread upon it to be dry'd: Then they are
to be put into a Stone-Mortar, and pounded with a Wooden-Pestle, till the Paste grows very thin, and begins to give Oil: This Paste is to be put into a little Linnen-Bag, new and strong, the Mouth of which hath been well ty'd; and the Bag is to be plac'd between two Platines of Tin, or of Wood lin'd on the inside with a Leaf of Tin, squeezing the whole Mass gently at first; but afterward very strongly, and leaving it for a long while in the Press, that the Oil may have time to run out.
This Oil mitigates the Nephritick Colicks, remedies the Retention of Urine, facilitates Child-birth, allayes the After-Pains in Women after their delivery, and the Gripes in young Infants: It is taken inwardly fasting from half an Ounce to two Ounces; and it is us'd in Liniments to asswage and mollifie. The Oils of common Wall-Nuts and Small-Nuts, may be also prepar'd after the same manner as that of Sweet-Almonds.
The Oil of Bayes.
Take as much as you please of Laurel or Bay-Berries, well cleans'd, perfectly ripe, and soundly bruis'd; let 'em be put into a Kettle, and boil'd with a sufficient quantity of Water during half an Hour; then strain and squeeze 'em strongly; let the Liquor cool, and scum off the Fat that swims upon the Water: Afterward pound the remaining Substance in a Mortar, and cause it to be boil'd again for half an Hour, with some of the first Water which was left, adding a little fresh; then strain and squeez it,
as before, and take off the Oil that swims on the Top. But the first Oil is better than the second, and therefore ought to be kept separately. The Oils of Berries of Mastick, Myrtle, and other oleaginous Plants, may be extracted after the same manner.
The Oil of Bayes mollifies, attenuates, and is opening and discussive: It is very good against the Palsie, and the Shiverings or cold Fits of a feaver or Ague in anointing the Back; as also against Scabs, Tetters, &c.
The Oil of Eggs by Expression.
Take newly laid Eggs, and let 'em be harden'd in Water; then separate the Yolks, and put 'em into a Frying-pan over a gentle Coal-fire, stirring 'em about from time to time, and at last without discontinuing, till they grow reddish, and begin to yield their Oil: Then they are to be sprinkl'd with Spirit of Wine, and pour'd very hot into a little Linnen-Bag, which is to be ty'd, and set in a Press between two heated Platines; so that the Oil may be squeez'd out as readily as is possible.
