Let the Gum _Ammoniack_, _Galbanum_, _Bdellium_, and _Opopanax_ be dissolv'd in Vinegar, in a little Earthen Pipkin; strain 'em thro' a course Cloth, and let 'em be thicken'd by Evaporation, according to the Method before observ'd in other Plaisters: Then prepare the Load-Stone upon a Porphyry or Marble-Stone, and take care to bruise separately, the _Olibanum_, the Mastick, the Myrrh, the round Birth-Wort, and the Verdegrease, which is to be kept to be added at last. In the mean while, having incorporated cold the Oil with the Litharge, and mingl'd the Water with 'em, they are to be boil'd together over a very good Fire, stirring 'em incessantly, till the whole Composition hath aquir'd the Consistence of a somewhat solid {332} Plaister, in which is to be dissolv'd the yellow Wax cut into small pieces. Afterward having taken off the Pan from the Fire, and left the Ingredients to be half cool'd, intermix the Gums, which have been already thicken'd and incorporated with the Turpentine; then the Load-Stone mingl'd with the Birth-Wort, Myrrh, Mastick, and _Olibanum_; and last of all the Verdegrease. Thus when all these Ingredients are well stirr'd and mixt together, the Plaister will be entirely compounded; so that it may be made up into Rolls, and preserv'd to be us'd upon necessary Occasions. This Plaister is efficacious in curing of all kinds of Wounds, Ulcers, Tumours, and Contusions; for it mollifies, digestes, and brings to Suppuration such Matter as ought to be carry'd off this way. It also mundifies, cicatrizes, and entirely consolidates Wounds, _&c._ * * * * * CHAP. IV. _Of Cataplasms or Pultisses._ Cataplasms are usually prepar'd to asswage Pain; as also to dissolve and dissipate recent Tumours, and are made thus: Take four Ounces and a half of white Bread, one Pint of new Milk, three Yolks of Eggs, one Ounce of Oil of Roses, one Dram of Saffron, and two Drams of the Extract of _Opium_. {333} The Crum is to be taken out of the inside of a white Loaf newly drawn out of the Oven, and to be boil'd with the Milk in a Skillet over a little Fire, stirring it from time to time with a _Spatula_, till it be reduc'd to a thick Pap. After having taken the Vessel off from the Fire, the three Yolks of Eggs beaten are to be put into it, and the Dram of Saffron pulveriz'd; to these Ingredients may be added two Drams of the Extract of _Opium_ somewhat liquid, if the Pain be great. _Here is another Cataplasm proper to mollifie and to bring to Suppuration when it is necessary._ Take White-Lilly-Roots, and Marsh-Mallow-Roots, of each four Ounces; the Leaves of common Mallows, Marsh-Mallows, Groundsel, Violet-Plants, Brank-Ursin, of every one of these Herbs one handful; the Meal of Line, Fenugreek, and Oil of Lillies, of each three Ounces.
