Part 10

“(1) The discoverer of this compound; (2) the purpose of the invention; and (3) the reasons why these drugs and no others of the multitude known to us have been chosen for this purpose.”

The lecturer then entered upon a history of Mithridates and his wonderful immunity against poisons; of his defeat by Pompey, of the recovery of his formula, of the additions made to it a hundred years later by Andromachus, and of the preservation of directions for making it which Galen wrote some fifty years after Andromachus had completed his invention.

At this point the book tells us there was an interval, and some music was performed. When the lecturer resumed he proceeded to tell of the risks which princes and nobles ran of being poisoned in those old times, and of the precautions taken against such crimes. Of the rings and amulets they wore, of the tasters they employed, and of the treatment such as Mithridates went through of accustoming his system to poisons to such an extent that they took no effect on him. He quotes in support of the belief in this method of ensuring immunity against poisons two or three stories from the classics which one would have thought would have been too strong even for a professional eulogist of Theriaca.

One case was that of a girl who ate spiders from her childhood, and was so fortified against poisons as not to be afraid to take any of them. A man is alluded to by Galen who would drink a cup of wine in which a live viper had been drowned. We have also the account of a girl whose system had been so saturated with aconite that an Indian king had sent her as a present to Alexander the Great in the hope that he would kiss her, and thus imbibe the poison with which her lips would be charged; but, fortunately, Aristotle saw her first, and recognised by her flaming eyes that she was filled with some sort of poison, and thus the Indian’s purpose was frustrated.

After another interval and some more music, the lecturer came to the third part of his subject, in which he expounded the special virtues of the drugs before him. These were grouped, and it was shown that some were good for the brain, others for the chest, for the stomach, for the kidneys, the heart, and other organs. Others, like the viper’s flesh, were directly sympathetic with poisons, and would go straight for them if they were inside the body, or would lie in wait for them, as it were, if they were only expected. When the subject was exhausted, it was announced that in consequence of the lateness of the hour the weighing of the ingredients would be postponed till the next day. That ceremony was duly performed on the 24th of September, and the drugs were passed on to a “pulveriser.” It was not until the 16th of November that the final mixing was undertaken.

KERMES.

Kermes as a pharmaceutical term reaches us through the Arabic, qirmis, red. But it was not a native Arabic word. It was adopted into that language from the Persian, and was of Sanskrit origin. The word Krimija in Sanskrit meant produced by a worm, and was itself from krimi, a worm; worm is the direct English descendant of krimi. Kermes is responsible in modern English for carmine and crimson, but it need hardly be said that it has no connection with the Flemish kermess though it looks so like it. Kermess is kerkmess, or, in English, church-mass.

The kermes of the Arabs was the kokkos of the Greeks, coccus of the Romans. It was found on a species of oak, now called the Quercus ilex, a low, shrubby, evergreen bush with prickly leaves like the holly. The tree, however, bears acorns. The ancients generally regarded these insects as the fruit of the trees, though they were aware that worms came from them. But these they thought were produced from the corruption of the fruit. The principal use they made of them was in dyeing, and for this purpose they were employed until the superior coccus cacti from Mexico superseded the coccus ilicis. In the middle ages kermes was retained as the medicinal name, but for dyeing the insects were called vermiculi, and the cloth dyed by them was known as vermiculata. From this came the French word vermeil, and from that vermilion was derived.

Medicinally the coccus was principally employed by the Greek and Latin physicians as an application to wounds and for inflamed eyes. It acquired a very high reputation among the Arab doctors as a cordial for internal administration, and the famous Confection of Alkermes, invented by Mesué the younger, who was contemporary with Avicenna, continued in popular favour up to the eighteenth century. Meanwhile, the external application of kermes lingered in the use of scarlet cloth in measles, erysipelas, and other red diseases.

The original Confection of Alkermes contained juice of rennet apples, rose water, silk, kermes, sugar, ambergris, amber, yellow santal, lapis lazuli, pearls, musk, and leaf gold. In the sixteenth and seventeenth centuries this compound was prepared publicly at Montpellier, and was supplied from that city to all Europe. It was described as good for all maladies proceeding from the melancholic humour, faintings, palpitations, heart weakness, and in slow convalescence. It fortified the stomach, rejoiced the heart, and engendered good spirits. The dose was 1 drachm, or it might be applied externally on a piece of scarlet cloth.

MEL ÆGYPTIACUM

is a very ancient compound used chiefly by veterinarians as an escharotic. Its name suggests Egyptian origin, but it has not been traced further back than to the “Grabadin” of John Mesué, the Arabian author, about the year 800. Scribonius Largus before him gives a similar formula under the name of Hygra. Mesué’s formula was to boil 1 oz. of vinegar with 1 oz. of honey to the consistence of honey and to add 2 drachms of verdigris. This formula was modified in various ways in the different pharmacopœias in which it was adopted; alum was added in some cases, cream of tartar in others. The chemical action varied with the process, but generally the result was to reduce a part of the verdigris to an oxide of copper, metallic copper, and a little basic acetate in different proportions. The compound appeared in the London Pharmacopœia of 1721 as Unguentum Ægyptiacum; in that of 1746 as Mel Ægyptiacum; as Oxymel Æruginis in that of 1788; and as Linimentum Æruginis in the P.L. 1851. In this last edition the formula given was to dissolve 1 oz. of verdigris in 7 oz. of vinegar, and boil this with 14 oz. of honey to a proper consistence. It was not adopted in the British Pharmacopœia. In old veterinary recipes it was often combined with tincture of myrrh to form a detergent liniment, and occasionally in a very diluted form was administered internally as a tonic. On the Continent, where its employment lingered longer than in this country, an Egyptiac of Solleysel, from which the vinegar was omitted, but litharge, sulphate of zinc, and arsenic in small proportions added, was frequently preferred to the original.

An Unguentum Ægyptiacum magis compositum, containing rock alum and sal ammoniac, in addition to the other ingredients mentioned, was included in the London Pharmacopœia 1721. In some foreign pharmacopœias camphor was prescribed as an ingredient, and in one old one theriaca is ordered.

TERRA SIGILLATA.

Various earths were celebrated as medicines in old times, that from the Island of Lemnos especially having been esteemed from the days of Herodotus among the Greeks, and this product retained its reputation in Western Europe down to the seventeenth century. It is still used by the Turks and neighbouring nations. The Lemnian earth is a greasy clay which is dug from a desolate hill in the island and consists of silica, alumina, chalk, and magnesia, with a little oxide of iron which gives it a red tint. It acquired the fame of being an antidote to all poisons, and was given in dysenteries, internal ulcers, and hæmorrhages; also in gonorrhœa, and in pestilential fevers. Externally it was applied to festering wounds. The characteristic of the best Lemnian earth was its greasy feel and freedom from grit.

A sufficient supply of this Lemnian earth is still, and has been certainly from the time of Galen, dug out of the hill only on one day of the year, with considerable ceremony and in the presence of the principal inhabitants of the island. At present the ceremony is largely a religious one, and the day fixed for it is the 6th of August, which in the Greek church calendar is the Fête of the Saviour. Formerly the ceremony was originally associated with the worship of Diana, and the date of the performance was the 6th of May. The particular earth may not be dug by any one on any other day of the year except that formally set apart for the operation. According to Dioscorides the earth was made up into a paste in his time with goats’ blood, but when Galen visited the place 150 years later he could find no evidence of this addition.

Lemnian earth was, and I presume still is, a monopoly of the Sultan of Turkey. Most of the produce of the day’s digging was sent to Constantinople and was made up into round tablets of about half an ounce in weight, which were stamped with designs similar to those shown in the accompanying sketches. At one time it is said the figure of Artemis (Diana) or the goat, which was one of her symbols appeared on the tablets, and it may be from this that the story of the goat’s blood originated.

Many other sealed earths were also more or less used in medicine, and were credited with similar virtues. The Terra Mellitea came from Malta and was alleged to have a special power against the bites of serpents, Malta, vipers, and St. Paul thus associating themselves in the public mind. These cakes bore the effigy of St. Paul, and a popular legend attributed their efficacy to a blessing on the earth of the island when the apostle landed there. There were besides Terra Samia, from the Isle of Samos; Terra Sicula or Fossil Bezoar from Sicily; Terra Portugallica, stamped with the figure of a rose, from Portugal; Terra Strigensis or Germanica from Strigonium in Hungary, stamped with a design, suggesting mountain peaks and cross-keys on them; and Terra Livonica. Naturally the temptation of selling soil at fabulous prices per shovelful appealed to all nations.

The appended formulas from Geoffroy’s Materia Medica (written before 1731) will show how this sealed earth was used. Both are for dysentery.

Lemnian earth, ʒi, syrup of quinces, 1 oz., plantain water, and knot grass water, of each 3 oz. Spoonful doses.

Lemnian earth, conserve of red roses, conserve of hips, of each ½ oz.; syrup of bearberries sufficient to make a soft electuary. Take ʒi morning and evening.

Several so-called “alexipharmic powders” or mixtures much more complex than the preceding were prescribed in small-pox, fevers, and pestilential diseases.

OIL OF BRICKS.

Oil of Bricks appeared in the earlier London and Edinburgh pharmacopœias and in many foreign formularies. It was long held to be a specially valuable application in gouty and rheumatic pains, and was especially in repute as a cure for deafness. It was also sometimes given as an internal remedy. Among its synonyms were those of oleum philosophorum, oleum sanctum, oleum divinum, and oleum benedictum; but as these names were adopted for selling purposes they may not have meant much. The process given in the P.L. 1746 was to heat bricks red-hot and quench them in olive oil until they had soaked up all the oil. They were then broken into small pieces and put into a retort, and by means of a sand-bath with a gradually increasing heat a distillate of oil and so-called spirit was obtained. The spirit was water impregnated with empyreumatic oil. The oil was nothing but an empyreumatic olive oil.

ARQUEBUSADE WATER

was the original of many vulnerary waters invented for application to wounds, bruises, and ulcers. It was a weak, spirituous distillate from a large number of herbs and aromatic plants, such as angelica, rosemary balm, hyssop, mint, rue, sage, and wormwood. These would furnish an antiseptic lotion. As the arquebus was displaced by the musket about the end of the sixteenth century it may be supposed that the lotion acquired its name and popularity at that same period; but these evidently lasted for a long time, as we find that a certain John Thomson took out a patent for “a concentrated balsam of arquebusade” in 1786.

FOUR THIEVES VINEGAR

is the sub-title of the Antiseptic Vinegar of the French Codex. It is a strong vinegar in which a number of aromatics with camphor and garlic have been macerated. The story of its origin is that in the year 1720 a plague was raging in the city of Toulouse, and that during the period of panic four thieves went about the city plundering the dead and dying. People wondered why they never took the disease, and when they were ultimately brought to justice and convicted, they were offered pardon if they would reveal the secret of their prophylactic. This is the legend as given by Littré, who quotes it from Abbé Lemontey. Other authors make Marseilles the scene of the exploit.
