  FIFTEEN REMEDIES DERIVED FROM CADMIA. TEN MEDICINAL EFFECTS OF CALCINED COPPER.

  Cadmia acts as a desiccative, heals wounds, arrests discharges, acts detergently upon webs and foul incrustations of the eyes, removes eruptions, and produces, in fact, all the good effects which we shall have occasion to mention when speaking of lead. Copper too, itself, when calcined, is employed for all these purposes; in addition to which it is used for white spots and cicatrizations upon the eyes. Mixed with milk, it is curative also of ulcers upon the eyes; for which purpose, the people in Egypt make a kind of eye-salve by grinding it upon whet stones. Taken with honey, it acts as an emetic. For these purposes, Cyprian copper is calcined in unbaked earthen pots, with an equal quantity of sulphur; the apertures of the vessel being well luted, and it being left in the furnace until the vessel itself has become completely hardened. Some persons add salt, and others substitute alum for sulphur; others, again, add nothing, but merely sprinkle the copper with vinegar. When calcined, it is pounded in a mortar of Thebaic stone, after which it is washed with rain water, and then pounded with a large quantity of water, and left to settle. This process is repeated until the deposit has gained the appearance of minium; after which it is dried in the sun, and put by for keeping in a box made of copper.

  THE SCORIA OF COPPER.

  The scoria, too, of copper is washed in the same manner; but the action of it is less efficacious than that of copper itself. The flower, too, of copper is also used in medicine; a substance which is procured by fusing copper, and then removing it into another furnace, where the repeated action of the bellows makes the metal separate into small scales, like the husks of millet, and known as “flower of copper.” These scales are also separated, when the cakes of metal are plunged into water: they become red, too, like the scales of copper known as “lepis,” by means of which the genuine flower of copper is adulterated, it being also sold under that name. This last is made by hammering nails that are forged from the cakes of metal. All these processes are principally carried on in the furnaces of Cyprus; the great difference between these substances being, that this lepis is detached from the cakes by hammering, whereas the flower falls off spontaneously.

  STOMOMA OF COPPER; FORTY-SEVEN REMEDIES.

  There is another finer kind of scale which is detached from the surface of the metal, like a very fine down, and known as “stomoma.” But of all these substances, and even of their names, the physicians, if I may venture so to say, are quite ignorant, as appears by the names they give them; so unacquainted are they with the preparation of medicaments, a thing that was formerly considered the most essential part of their profession. At the present day, whenever they happen to find a book of recipes, if they wish to make any composition from these substances, or, in other words, to make trial of the prescription at the expense of their unhappy patients, they trust entirely to the druggists, who spoil everything by their fraudulent adulterations. For this long time past, they have even purchased their plasters and eye-salves ready made, and the consequence is, that the spoiled or adulterated wares in the druggists’ shops are thus got rid of.

  Both lepis and flower of copper are calcined in shallow earthen or brazen pans; after which they are washed, as described above, and employed for the same purposes; in addition to which, they are used for excrescences in the nostrils and in the anus, as also for dullness of the hearing, being forcibly blown into the ears through a tube. Incorporated with meal, they are applied to swellings of the uvula, and, with honey, to swellings of the tonsils. The scales prepared from white copper are much less efficacious than those from Cyprian copper. Sometimes they first macerate the nails and cakes of copper in a boy’s urine; and in some instances, they pound the scales, when detached, and wash them in rain water. They are then given to dropsical patients, in doses of two drachmæ, with one semisextarius of honied wine: they are also made into a liniment with fine flour.

  VERDIGRIS; EIGHTEEN REMEDIES.

  Verdigris is also applied to many purposes, and is prepared in numerous ways. Sometimes it is detached already formed, from the mineral from which copper is smelted: and sometimes it is made by piercing holes in white copper, and suspending it over strong vinegar in casks, which are closed with covers; it being much superior if scales of copper are used for the purpose. Some persons plunge vessels themselves, made of white copper, into earthen pots filled with vinegar, and scrape them at the end of ten days. Others, again, cover the vessels with husks of grapes, and scrape them in the same way, at the end of ten days. Others sprinkle vinegar upon copper filings, and stir them frequently with a spatula in the course of the day, until they are completely dissolved. Others prefer triturating these filings with vinegar in a brazen mortar: but the most expeditious method of all is to add to the vinegar shavings of coronet copper. Rhodian verdigris, more particularly, is adulterated with pounded marble; some persons use pumice-stone or gum.

  The adulteration, however, which is the most difficult to detect, is made with copperas; the other sophistications being detected by the crackling of the substance when bitten with the teeth. The best mode of testing it is by using an iron fire-shovel; for when thus subjected to the fire, if pure, the verdigris retains its colour, but if mixed with copperas, it becomes red. The fraud may also be detected by using a leaf of papyrus, which has been steeped in an infusion of nut-galls; for it becomes black immediately upon the genuine verdigris being applied. It may also be detected by the eye; the green colour being unpleasant to the sight. But whether it is pure or adulterated, the best method is first to wash and dry it, and then to burn it in a new earthen vessel, turning it over until it is reduced to an ash; after which it is pounded and put by for use. Some persons calcine it in raw earthen vessels, until the earthenware becomes thoroughly baked: others again add to it male frankincense. Verdigris is washed, too, in the same manner as cadmia.

  It affords a most useful ingredient for eye-salves, and from its mordent action is highly beneficial for watery humours of the eyes. It is necessary, however, to wash the part with warm water, applied with a fine sponge, until its mordency is no longer felt.

  HIERACIUM.

  “Hieracium” is the name given to an eye-salve, which is essentially composed of the following ingredients; four ounces of sal ammoniac, two of Cyprian verdigris, the same quantity of the kind of copperas which is called “chalcanthum,” one ounce of misy and six of saffron; all these substances being pounded together with Thasian vinegar and made up into pills. It is an excellent remedy for incipient glaucoma and cataract, as also for films upon the eyes, eruptions, albugo, and diseases of the eye-lids. Verdigris, in a crude state, is also used as an ingredient in plasters for wounds. In combination with oil, it is wonderfully efficacious for ulcerations of the mouth and gums, and for sore lips. Used in the form of a cerate, it acts detergently upon ulcers, and promotes their cicatrization. Verdigris also consumes the callosities of fistulas and excrescences about the anus, either used by itself, applied with sal ammoniac, or inserted in the fistula in the form of a salve. The same substance, kneaded with one third part of resin of turpentine, removes leprosy.

  SCOLEX OF COPPER; EIGHTEEN REMEDIES.

  There is another kind of verdigris also, which is called “scolex.” 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 repuls
ive 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, 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.

  CHALCITIS: SEVEN REMEDIES.

  Chalcitis 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, of which last we shall speak in their appropriate places. 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 as- tringently upon the gums, the uvula, and the tonsillary glands. 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.” 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.

  SORY: THREE REMEDIES.

  The sory 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.

  MISY: THIRTEEN REMEDIES.

  Some persons have stated, that misy is formed by the calcination of the mineral, in trenches; 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.

  CHALCANTHUM, OR SHOEMAKERS’ BLACK: SIXTEEN REMEDIES.

  The Greeks, by the name which they have given to it, have indicated the relation between shoemakers’ black and copper; for they call it “chalcanthum.” Indeed there is no substance 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 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.

  Chalcanthum is also prepared in various other ways: the earth which contains it being sometimes excavated into trenches, from the sides of which globules exude, which become concrete when exposed to the action of the winter frosts. This kind is called “stalagmia,” and there is none more pure. When its colour is nearly white, with a slight tinge of violet, it is called “lonchoton.” It is also prepared in pans hollowed out in the rocks; the rain water carrying the slime into them, where it settles and becomes hardened. It is also formed in the same way in which we prepare salt; the intense heat of the sun separating the fresh water from it. Hence it is that some distinguish two kinds of chalcanthum, the fossil and the artificial; the latter being paler than the former, and as much inferior to it in quality as it is in colour.

  The chalcitis which comes from Cyprus is the most highly esteemed for the purposes of medicine, being taken in doses of one drachma with honey, as an expellent of intestinal worms. Diluted and injected into the nostrils, it acts detergently upon the brain, and, taken with honey or with hydromel, it acts as a purgative upon the stomach. It removes granulations upon the eye-lids, and is good for pains and films upon the eyes; it is curative also of ulcerations of the mouth. It arrests bleeding at the nostrils, and hæmorrhoidal discharges. In combination with seed of hyoscyamus, it brings away splinters of broken bones. Applied to the forehead with a sponge, it acts as a check upon defluxions of the eyes. Made up into plasters, it is very efficacious as a detergent for sores and fleshy excrescences in ulcers. The decoction of it, by the contact solely, is curative of swellings of the uvula. It is laid with linseed upon plasters which are used for relieving pains. The whitish kind is preferred to the violet in one instance only, for the purpose of being blown into the ears, through a tube, to relieve deafness. Applied topically by itself, it heals wounds; but it leaves a discoloration upon the scars. It has been lately discovered, that if it is sprinkled upon the mouths of bears and lions in the arena, its astringent action is so powerful as to deprive the animals of the power of biting.

  POMPHOLYX.

  The substances called pompholyx and spodos are also found in the furnaces of copper-smelting works; the difference between them being, that pompholyx is disengaged by washing, while spodos is not washed. Some persons have called the part which is white and very light “pompholyx,” and say that it is the ashes of copper and cadmia; whereas spodos is darker and heavier, being a substance scraped from the walls of the furnace, mixed with extinguished sparks from the metal, and sometimes with the residue of coals. When vinegar is combined with it, pompholyx emits a coppery smell, and if it is touched with the tongue, the taste is most abominable. It is useful as an ingredient in ophthalmic preparations for all diseases of the eyes,
as also for all the purposes for which spodos is used; this last only differing from it in its action being less powerful. It is also used for plasters, when required to be gently cooling and desiccative. For all these purposes it is more efficacious when it has been moistened with wine

  SPODOS; FIVE REMEDIES.

  The Cyprian spodos is the best. It is formed by fusing cadmia with copper ore. This substance, which is the lightest part of the metal disengaged by fusion, escapes from the furnace, and adheres to the roof, being distinguished from the soot by the whiteness of its colour. Such parts of it as are less white are indicative of incomplete combustion, and it is this which some persons call “pompholyx.” Such portions of it as are of a more reddish colour are possessed of a more energetic power, and are found to be so corrosive, that if it touches the eyes, while being washed, it will cause blindness. There is also a spodos of a honey colour, an indication that it contains a large proportion of copper. All the different kinds, however, are improved by washing; it being first skimmed with a feather, and afterwards submitted to a more substantial washing, the harder grains being removed with the finger. That, too, which has been washed with wine is more modified in its effects; there being also some difference according to the kind of wine that is used. When it has been washed with weak wine the spodos is considered not so beneficial as an ingredient in medicaments for the eyes; but the same kind of preparation is more efficacious for running sores, and for ulcers of the mouth attended with a discharge of matter, as well as in all those remedies which are used for gangrene.
