Part 46

ALCHEMICAL HOPES OF ANTIMONY.

The alchemists and the early chemical physicians had great hopes of antimony. “They tormented it in every possible manner,” says Fourcroy, “in the hope of getting from it a universal remedy.” With it, too, they were convinced that they were coming near to the transmutation of other metals into gold. Noticing how readily it formed alloys with other metals they named it Lupus Metallorum, the Wolf of Metals. Their process for getting the Powder of Projection, as well as can be gathered from their mystic jargon was to first fuse the crude antimony, the sulphide, with iron which withdrew the sulphur from the antimony. The metal thus obtained they called the Martial Regulus of Antimony. Regulus, or little king, implied an impure gold. Combining this with corrosive sublimate and silver, and subliming the mixture they got the lunar butter of antimony. The sublimation had to be repeated eight or ten times, the residue, or fæces, being added to the sublimate every time. At last the sublimed butter of antimony was transferred to an oval glass vessel capable of containing twelve times its quantity, and hermetically sealed. The Philosophic Egg, as the vessel with its contents was called, was then placed in a sand-bath and kept at a moderate heat for several months. When it had become converted into a red powder, the operation was finished. This powder was the Powder of Projection. It was sprinkled on other metals in a state of fusion, mercury being an ingredient of the fused mass, and yellow gold was produced.

ANTIMONIAL COMPOUNDS.

By other processes the early experimenters obtained various other products. By simply heating crude antimony in a crucible they would sometimes get a vitreous substance in consequence of some of the silica of the crucible combining with the antimony. That was their glass of antimony, which was generally an oxide with some sulphide. In other cases the so-called liver of antimony resulted, a compound containing a larger proportion of the sulphide. This they also called crocus metallorum or saffron of the metals, and one or other of these products was originally the basis of antimonial wine.

It was digested with Rhine wine, and the tartar of the wine formed a tartrate of antimony, but, as may be supposed, the composition of the wine was very variable. Emetic tartar was subsequently substituted for the liver.

The crystalline protoxide of antimony obtained by inflaming, volatilising, and condensing the regulus was known as argentine flowers of antimony. The regulus heated with nitric acid yielded a compound of metal with antimonious acid, and was called mineral bezoar; a compound, really a suboxide, got by fusing sulphide of antimony and nitre was called diaphoretic antimony; the chloride, first made by distilling crude antimony (the native sulphide) with corrosive sublimate, yielded the thick soft butter of antimony; the addition of water to this chemical caused the precipitation of a white oxychloride which was long known as Algaroth’s powder, or mercury of life. It contained no mercury, but was the most popular emetic before the introduction of the tartrate. Victor Algarotti, who introduced it, was a physician, of Verona, who died in 1603. It was alleged that he was poisoned by his local rivals in consequence of the success of his remedy. He was also the inventor of a quintessence of gold.

The regulus of antimony in alloy with some tin was used to make the antimony cups from which antimonial wine originated. It was also made into the pilulæ perpetuæ, or everlasting pills, which, passing through the body almost unchanged, were kept as a family remedy and taken again and again. It is probable that the surface of these pills became slightly oxidised, and consequently acquired a medicinal effect.

KERMES MINERAL.

One of the most famous of the antimony compounds was the kermes mineral, which it is understood was invented by Glauber about 1651. He made it by treating a solution of the oxide of antimony with cream of tartar, and then passing a current of sulphuretted hydrogen through the solution. An orange-red powder was obtained, and famous cures were effected by it. Glauber kept his process secret, but a Dr. de Chastenay learnt it after Glauber’s death from one of his pupils and confided it to a surgeon named La Ligerie, who in his turn communicated it to Brother Simon, a Carthusian monk, who at once commenced successfully to treat his brother monks with it, and soon after the Poudre des Chartres was one of the most popular remedies in France for many serious diseases, small-pox, ague, dropsy, syphilis, and many others. In 1720 Louis XIV bought the formula for its preparation for a considerable sum from La Ligerie. It has been agreed by chemists, Berzelius and others, who have studied Kermes Mineral, that it is a mixture of about 40 per cent. or less of oxide of antimony with a hydrated sulphide of the metal, and a small proportion of sulphide of sodium or potassium (according to the method of preparation). It is still official in the Pharmacopœias of the United States and of many Continental countries.

From the solution from which the Kermes had been deposited a further precipitate was obtained by the addition of hydrochloric acid. This, too, was a mixture, consisting of protosulphide and persulphide of antimony with some sulphur. It was the golden sulphuret which in association with calomel became so noted in the form of Plummer’s powder and Plummer’s pills. The powder was at first known as Plummer’s Æthiops Medicinalis.

It would be tedious to go through the multitude of antimonial compounds which have become official, and it would be impossible in any reasonable space even to enumerate the quack medicines with an antimonial base which were so recklessly sold in this and other countries, especially in the earlier half of the seventeenth century. The most important of all the antimonial compounds, or, at least, the one which has maintained the favour of the medical profession in all countries, is, of course, the tartrate of antimony and potassium, emetic tartar.

EMETIC TARTAR.

Adrian Mynsicht, physician to the Duke of Mecklenburg in the early part of the seventeenth century, is generally credited with the invention of emetic tartar. Certainly the earliest known description of it is found in his “Thesaurus Medico-Chymicum,” published in 1631. But Hofer has pointed out that the mixture known as the Earl of Warwick’s Powder, which consisted of scammony, diaphoretic antimony (a binantimoniate of potash) and cream of tartar, which Cornachinus of Pisa described in 1620, was really its forerunner, and he considers that the salt was recognised in medicine before Mynsicht published his description.

Glauber, in 1648, described the process of making Mynsicht’s emetic tartar from cream of tartar and argentine flowers of antimony.

ANTIMONY CONTROVERSY.

No medicine has been more violently attacked or so enthusiastically praised as antimony. The virulent antagonism to it manifested by the Faculty of Physicians of Paris was unquestionably the exciting cause of much of the fame to which it attained. It is generally stated that on the instigation of the Faculty the Parliament of Paris decreed that it should not be employed in medicines at all. This, however, has been proved to be incorrect. Certainly the Faculty in 1566 did, in fact, forbid its own licentiates to use it, and actually expelled one of their most able associates, Turquet de Mayerne, because he had disobeyed their injunction. But M. Teallier has shown by documentary evidence that the decree of the Parliament did not go beyond requiring that antimony should not be supplied for medicinal use except on the order of a qualified physician. The action of the Faculty, although approved for a time, was later almost disregarded, and when the court physicians cured the young king, Louis XIV, in 1657, by the administration of antimony, the defeat of the anti-antimonists was completed. The repeal of the decree against antimonials was dated 1666, just a century after its promulgation.

Louis XIV was taken dangerously ill at Calais, in 1657, when he was 19 years of age. A physician (Voltaire says a quack) of Abbeville had the audacity to treat him by the administration of emetic tartar, and the King himself and his Court were convinced that he owed his life to this remedy. The opponents of antimony were silenced, though they did not yield in their opinion. Gui Patin, who had termed the new medicine “tartre stygiè” (its usual French name was tartre stibié), protested against the attempt to canonise this poison, and asserted that the cure of the king was due to his own excellent constitution.

To illustrate the earnestness, not to say the ferocity, of medical controversy at the beginning of the seventeenth century, the record of the expulsion of Turquet de Mayerne from the College of Physicians of Paris, in 1603, quoted from the minutes of the College and translated by Nedham, may be given. It should be remembered that Turquet was the favourite physician of Henri IV, and, nominally, his offence was that he had published a defence of his friend, Quercetanus, who had prescribed mercurial and antimonial medicines. The minute is in the following terms:--

The College of Physicians in the University of Paris, being lawfully congregated, having heard the Report made by the Censor to whom the business of examining the Apology published under the name of Turquet de Mayerne, was committed, do with unanimous consent condemn the same as an infamous libel, stuffed with lying reproaches and impudent calumnies, which could not have proceeded from any but an unlearned, impudent, drunken, mad fellow: And do judge the said Turquet to be unworthy to practise physick in any place because of his rashness, impudence, and ignorance of true physick: But do exhort all physicians which practise Physick in any nations or places whatsoever that they will drive the said Turquet and such like monsters of men and opinions out of their company and coasts; and that they will constantly continue in the doctrine of Hippocrates and Galen. Moreover, they forbid all men that are of the Society of the Physicians of Paris, that they do not admit a consultation with Turquet or such like person. Whosoever shall presume to act contrary shall be deprived of all honours, emoluments, and privileges of the University and be expunged out of the regent Physicians. Dated December 5, 1603.

ANTIMONY CUPS (POCULA EMETICA)

were in use in the sixteenth and seventeenth centuries, more perhaps in Germany than in this country. The one illustrated is in the Museum of Practical Geology, Jermyn Street. It was bought for a shilling at a sale at Christies’ in 1858, and was described in the catalogue as “An old metal cup, with German inscription and coronet, gilt, in woodcase.” The cups are said to have been made of an alloy of tin and antimony, and wine standing for a time in one of them would become slightly impregnated with emetic tartar, the tartar of the wine acting on the film of oxide of antimony which would form on the inner surface of the cup. How far these cups were used in families does not appear, but it is said they were common in monasteries, and that monks who took too much wine were punished by having to drink some more which had been standing in the poculum emeticum. Dr. Walter Harris, in “Pharmacopœia Anti-Empirica” (1683) refers to the cups, and says, “their day is pretty well over. It is rare to meet with one now.”

It was supposed by the early chemical physicians that antimony imparted emetic properties to wine without any loss of weight. Angelo Sala tells of a German who attained some fame in his time by letting out a piece of glass of antimony on hire. The patient was instructed to immerse this in a cup of wine for three, four, or five hours (according to the strength of the person prescribed for), and then to drink the wine. The practitioner charged a fee of a dozen fresh eggs for the use of his stone, and, as he had hundreds of clients, patients had to wait their turn for their emetic.

BISMUTH.

Bismuth, the metal, was not known to the ancients nor to the Arabs. It was first mentioned under that name by Agricola, in 1546, in “De Natura Fossilium,” and was not then regarded as a distinct body. Agricola considered it to be a form of lead, and other mining chemists believed that it gradually changed into silver. The Magistery (trisnitrate or oxynitrate) was the secret blanc de fard which Lemery sold in large quantities as a cosmetic. He bought the secret from an unknown chemist and made a large fortune out of it. His process was to dissolve one ounce of the metal in two ounces of nitric acid and to pour on the solution five or six pints of water in which one ounce of sea-salt had been dissolved. The sea-salt would yield a proportion of bismuth oxychloride in the precipitate. Lemery made a pomatum, ʒi to the ounce, and a lotion, ʒi to ʒiv of lily water.

Until the latter part of the eighteenth century bismuth salts were regarded as poisonous and were scarcely used in medicine by way of internal administration. Even Odier, of Geneva, to whom we owe the introduction of this medicine in dyspepsia and diarrhœa, prescribed it in 1 grain doses with 10 grains each of magnesia and sugar.

Lemery says the bismuth of his time was a compound made in England from the gross and impure tin found in the English mines. “The workmen mix this tin with equal parts of tartar and saltpetre. This mixture they throw by degrees into crucibles made red hot in a large fire. When this is melted they pour it into greased iron mortars and let it cool. Afterwards they separate the regulus at the bottom from the scoriæ and wash it well. This is the tin-glass, which may be called the regulus of tin.” Pomet says much the same about the composition. He adds, “It is so true that tin-glass is artificial that I have made it myself, and am ready to show it to those who won’t believe me.”

Those writers belonged to the first quarter of the eighteenth century. A quarter of a century later Quincy is telling us that the metal called Bismuth “is composed of tin, tartar, and arsenic, made in the northern parts of Germany, and from thence brought to England.”
