CHAP. 28. (12.)—SCOLEX OF COPPER; EIGHTEEN REMEDIES.
There is another kind of verdigris also, which is called “scolex.”[1626] It is prepared by triturating in a mortar of Cyprian copper, alum and salt, or an equal quantity of nitre, with the very strongest white vinegar. This preparation is only made during the hottest days of the year, about the rising of the Dog-star. The whole is triturated until it becomes green, and assumes the appearance of small worms, to which it owes its name. This repulsive form is corrected by mixing the urine of a young child, with twice the quantity of vinegar. Scolex is used for the same medicinal purposes as santerna, which we have described as being used for soldering gold,[1627] and they have, both of them, the same properties as verdigris. Native scolex is also procured by scraping the copper ore of which we are about to speak.
CHAP. 29.—CHALCITIS: SEVEN REMEDIES.
Chalcitis[1628] is the name of a mineral, from which, as well as cadmia, copper is extracted by heat. It differs from cadmia in this respect, that this last is procured from beds below the surface, while chalcitis is detached from rocks that are exposed to the air. Chalcitis also becomes immediately friable, being naturally so soft as to have the appearance of a compressed mass of down. There is also this other distinction between them, that chalcitis is a composition of three other substances, copper, misy, and sory,[1629] of which last we shall speak in their appropriate places.[1630] The veins of copper which it contains are oblong. The most approved kind is of the colour of honey; it is streaked with fine sinuous veins, and is friable and not stony. It is generally thought to be most valuable when fresh, as, when old, it becomes converted into sory. It is highly useful for removing fleshy excrescences in ulcers, for arresting hæmorrhage, and, in the form of a powder, for acting astringently upon the gums, the uvula, and the tonsillary glands.[1631] It is applied in wool, as a pessary, for affections of the uterus; and with leek juice it is formed into plasters for diseases of the genitals. This substance is macerated for forty days in vinegar, in an earthen vessel luted with dung; after which it acquires a saffron colour. When this composition is mixed with an equal proportion of cadmia, it forms the medicament known as “psoricon.”[1632] If two parts of chalcitis are combined with one of cadmia, the medicament becomes more active; and it is rendered still more powerful if vinegar is used instead of wine. For all these purposes, calcined chalcitis is the most efficacious.
CHAP. 30.—SORY: THREE REMEDIES.
The sory[1633] of Egypt is the most esteemed, being considered much superior to that of Cyprus, Spain, and Africa; although some prefer the sory from Cyprus for affections of the eyes. But from whatever place it comes, the best is that which has the strongest odour, and which, when triturated, becomes greasy, black, and spongy. It is a substance so unpleasant to the stomach, that some persons are made sick merely by its smell. This is the case more particularly with the sory from Egypt. That from other countries, by trituration, acquires the lustre of misy, and is of a more gritty consistency. Held in the mouth, and used as a collutory, it is good for toothache. It is also useful for malignant ulcers of a serpiginous nature. It is calcined upon charcoal, like chalcitis.
CHAP. 31.—MISY: THIRTEEN REMEDIES.
Some persons have stated, that misy[1634] is formed by the calcination of the mineral, in trenches;[1635] its fine yellow powder becoming mixed with the ashes of the burnt fire-wood. The fact is, however, that though obtained from the mineral, it is already formed, and in compact masses, which require force to detach them. The best is that which comes from the manufactories of Cyprus, its characteristics being, that when broken, it sparkles like gold, and when triturated, it presents a sandy or earthy appearance, like chalcitis. Misy is used in the process of refining gold. Mixed with oil of roses, it is used as an injection for suppurations of the ears, and, in combination with wool, it is applied to ulcers of the head. It also removes inveterate granulations of the eye-lids, and is particularly useful for affections of the tonsils, quinsy, and suppurations. For these maladies, sixteen drachmæ should be mixed with one semisextarius of vinegar, and boiled with the addition of some honey, until it becomes of a viscous consistency; in which state it is applicable to the different purposes above mentioned. When its action is wanted to be modified, a sprinkling of honey is added. A fomentation of misy and vinegar removes the callosities of fistulous ulcers; it also enters into the composition of eye-salves. It arrests hæmorrhage, prevents the spreading of serpiginous and putrid ulcers, and consumes fleshy excrescences. It is particularly useful for diseases of the male generative organs, and acts as a check upon menstruation.
CHAP. 32.—CHALCANTHUM, OR SHOEMAKERS’ BLACK: SIXTEEN REMEDIES.
The Greeks, by the name[1636] which they have given to it, have indicated the relation between shoemakers’ black[1637] and copper; for they call it “chalcanthum.”[1638] Indeed there is no substance[1639] so singular in its nature. It is prepared in Spain, from the water of wells or pits which contain it in dissolution. This water is boiled with an equal quantity of pure water, and is then poured into large wooden reservoirs. Across these reservoirs there are a number of immovable beams, to which cords are fastened, and then sunk into the water beneath by means of stones; upon which, a slimy sediment attaches itself to the cords, in drops of a vitreous[1640] appearance, somewhat resembling a bunch of grapes. Upon being removed, it is dried for thirty days. It is of an azure colour, and of a brilliant lustre, and is often taken for glass. When dissolved, it forms the black dye that is used for colouring leather.
