A History of Inventions, Discoveries, and Origins, Volume I (of 2)

According to information procured in the year 1731, the island of Teneriffe produced annually five hundred quintals of this moss; Canary, four hundred; Forteventura, Lancerotta, and Gomera, three hundred each; and Fero, eight hundred; making in all two thousand six hundred quintals. In the islands of Canary, Teneriffe and Palma, the moss belongs to the crown; and in the year 1730 it was let by the king of Spain for one thousand five hundred piastres. The farmers paid then for collecting it from fifteen to twenty rials per hundred weight81. In the rest of the islands it belongs to private proprietors, who cause it to be collected on their own account. In the beginning of the last century a hundred weight, delivered on board at Santa Cruz, the capital of Teneriffe, was worth from only three to four piastres; but since 1725 it has cost labour amounting to ten piastres, because it has been in great request at London, Amsterdam, Marseilles, and throughout all Italy82. In the year 1726 this lichen cost at London eighty pounds sterling per ton, as we are told by Dillenius, and in 1730 it bore the same price.

Towards the end of the year 1730, the captain of an English vessel, which came from the Cape de Verde islands, brought a bag of archil to Santa Cruz by way of trial. He discovered his secret to some Spanish and Genoese merchants, who, in the month of July 1731, resolved to send a ship to these islands. They landed on that of St. Anthony and St. Vincent, where in a few days they obtained five hundred quintals of this lichen, which they found in such abundance, that it cost them nothing more than a piastre per cent. by way of present to the governor. The archil of the Cape de Verde islands appears larger, richer, and longer than that of the Canaries, and this, perhaps, is owing to its not being collected every year83. Adanson, in 1749, found also the greater part of the rocks in Magdalen island, near Senegal, covered with this lichen. Though the greater part of our archil is at present procured from the Canary and Cape de Verde islands, a considerable quantity is procured also from the Levant, from Sicily, as Glass says, and from the coast of Barbary; and some years ago the English merchants at Leghorn caused this lichen to be collected in the island of Elba, and paid a high price for it84.

Our dyers do not purchase raw archil, but a paste made of it, which the French call orseille en pâte. The preparation of it was for a long time kept a secret by the Florentines. The person who, as far as I know, made it first known was Rosetti; who, as he himself tells us, carried on the trade of a dyer at Florence. Some information was afterwards published concerning it by Imperati85 and Micheli the botanist86. In later times this art has been much practised in France, England, and Holland. Many druggists, instead of keeping this paste in a moist state with urine, as they ought, suffer it to dry, in order to save a little dirty work. It then has the appearance of a dark violet-coloured earth, with here and there some white spots in it.

The Dutch, who have found out better methods than other nations of manufacturing many commodities, so as to render them cheaper, and thereby to hurt the trade of their neighbours, are the inventors also of lacmus87, a preparation of archil called orseille en pierre, which has greatly lessened the use of that en pâte, as it is more easily transported and preserved, and fitter for use; and as it is besides, if not cheaper, at least not dearer. This art consists, undoubtedly, in mixing with that commodity some less valuable substance, which either improves or does not much impair its quality, and which at the same time increases its weight88. Thus they pound cinnabar and smalt finer than other nations, and yet sell both these articles cheaper. In like manner they sift cochineal, and sell it at a less price than what is unsifted.

It was for a long time believed that the Dutch prepared their lacmus from those linen rags which in the south of France are dipped in the juice of the Croton tinctorium89; and this idea appeared the more probable, as most of this tournesol en drapeaux was bought up by the Hollanders: but, as they are the greatest adulterators of wine in Europe, they may perhaps have used these rags to colour Pontack and other wines. It is however not improbable that they at first made lacmus of them, as their dye approaches very near to that of archil. At present it is almost certainly known that orseille en pâte is the principal ingredient in orseille en pierre, that is in lacmus90: and for this curious information we are indebted to Ferber91. But whence arises the smell of the lacmus, which appears to me like that of the Florentine iris? Some of the latter may, perhaps, be mixed with it; for I think I have observed in it small insoluble particles, which may have been pieces of the roots. The addition of this substance can be of no use to improve the dye; but it may increase the weight, and give the lac more body; and perhaps it may be employed to render imperceptible some unpleasant smell, for which purpose the roots of that plant are used on many other occasions.

Another kind of lichen, different from the roccella, which in commerce is known by the names orseille de terre, orseille d’Auvergne, is used also for the like purpose; but it contains fewer and weaker colouring particles. This species, in botany, is called Lichen Parellus (Lecanora Parella), and is distinguished from the roccella by its figure, as it grows only in a thin rind on the rocks. It is collected in Auvergne, on rocks of granite and volcanic productions, and in some parts of Languedoc; the greater part of it is brought from St. Flour. Its name, perelle, comes from an old Languedocian word pére (pierre, a rock); as roccella, afterwards transformed into orseille, is derived from rocca. The use of perelle is very trifling: the Dutch purchase it to make lacmus, perhaps on account of its low price. This lichen has been found also in Northumberland92 and other mountainous districts of Great Britain, but it is not collected there for any purpose.

MAGNETIC CURES

The external use of the magnet, to cure the tooth-ache and other disorders, is a remedy brought into fashion in modern times, but not a new discovery, as supposed by Lessing, who ascribes it to Paracelsus93. It was known to Aëtius, who lived so early as the year 500. That author says, “We are assured that those who are troubled with the gout in their hands or their feet, or with convulsions, find relief when they hold a magnet in their hand94.” He does not however give any proof of this from his own experience: and perhaps he doubted the truth of it. The above passage contains the oldest account known at present respecting this virtue; for the more ancient writers speak only of the internal use of the magnet.

It is evident therefore that this cure has not been discovered in later times, but that it has been preserved by the old physicians copying it from each other into their works. In like manner, many things are mentioned in the Materia Medica which were used or proposed by the ancients, but into the properties of which they never made sufficient inquiry.

Paracelsus recommended the magnet in a number of diseases, as fluxes, hæmorrhages, &c. Marcellus, who lived in the fifteenth century, assures us that it cures the tooth-ache95. The same virtue is ascribed to it by Leonard Camillus96, who lived in the sixteenth century: and Wecker97, who was nearly co-temporary, says that the magnet when applied to the head, cures the head-ache; and adds that Holler had taken this cure from the works of the ancients98. We read also in Porta99, that it was recommended for the head-ache; and in Kircher100, that it was worn about the neck as a preventive against convulsions, and affections of the nerves. About the end of the 17th century magnetic tooth-picks and ear-pickers were made, and extolled as a secret preventive against pains in the teeth, eyes and ears101.

[In addition to these external uses of the magnet, in which it was supposed to act by a peculiar power over the nervous system, it has been employed on account of its true magnetic properties. Thus Kirkringius, Fabricius Hildanus, and subsequently Morgagni, have used it to remove particles of iron which had accidentally fallen into the eyes. Kircher employed it also to cure hernia. The patient took iron-filings internally; and the loadstone in the state of powder mixed with some vegetable substance, thus forming a magnetic plaster, was applied to the hernia. Even Ambrose Paré states on the authority of a surgeon, that several patients had been thus cured.

About the 16th and early in the 17th century, two cases occurred, one near Prague in Bohemia, the other in Prussia, in which a knife was swallowed, but it unfortunately got too far and passed into the stomach. By the application of these magnetic plasters, the point became attracted towards the surface, so that it could be removed by incision102.

In the 18th century, after the properties of magnets had begun to be scientifically investigated, they were made of various forms and their effects studied in numerous parts of Europe, and many treatises were published on their supposed properties. Perhaps the most important and best authenticated, are those of MM. Audry and Thouret. These experimenters believed that they were effective agents.

Since that time, the use of magnets as remedial agents has been almost entirely laid aside and forgotten, it having been found that no constancy was exhibited in the results of their application, and that their occasional supposed efficacy depended upon other circumstances, which were overlooked from the sufferers’ attention being engrossed by the magnet. The application of the magnet to remove small particles of iron or steel which have accidentally fallen into the eyes, has been lately revived. In some manufactories, where these minute particles are constantly thrown off in the grinding of hardware and driven into the eyes, large magnets are kept fixed at a proper height, so that the workmen can resort to them immediately. Such is the case for instance at Fairbairne in Belgium, and we believe the same has been adopted in some of our own manufactories to catch the floating particles, and thus to prevent their being drawn into the lungs during respiration. The reader may form some idea of the effective manner in which magnets can be applied, from the following incident which occurred to Prof. Faraday, whilst experimenting with a powerful (electro-) magnet; an iron candlestick which happened to be standing near its poles on the table at which he was at work flew to them, attracted with such violence as to displace or break everything in its way.

In the 18th century, a new supposed magnetic power was discovered, and with various success has continued to be applied to the delusion of the public. About 1770, Father Hehl, a jesuit, the Professor of Astronomy at Vienna, who had great faith in the influence of the loadstone on human diseases, and had invented steel plates of a peculiar form, which he impregnated with magnetic virtues and applied to the cure of diseases, communicated his discoveries to Anton Mesmer, who subsequently invented animal magnetism or mesmerism. Mesmer made use of his friend Hehl’s plates to employ the magnet according to certain notions of his own. In his subsequent experiments magnets were gradually dispensed with, and as practised in modern times, they have been found unnecessary. Hence mesmerism or animal magnetism has no relation to the magnetism of the magnet, and may therefore form the subject of a future article.

About the year 1798, a man named Perkins invented a method of treating various diseases with metallic bars called tractors; these were applied to and drawn over various parts of the body, and were supposed to cure numerous maladies, such as ulcers, head-aches, &c. These instruments were patented. A few years afterwards, Dr. Falconer had wooden tractors made so exactly to resemble those of Perkins, that they could not be distinguished by the eye; on employing these on a large scale at the Bath hospital, he found that exactly the same effects and cures were produced by one as the other. Since that time these tractors have hardly been heard of, and are now forgotten.

Quite recently, a new means has been contrived in England for deluding the public, in the form of rings, which are to be worn upon the fingers or toes, and are said to prevent the occurrence of, and cure various diseases. They are called galvanic rings. But this invention may be with propriety classed with the real magnet, animal magnetism and tractation.

What has been stated relative to the metallic tractors, equally applies to the magnetic rings; for although by the contact of the two metals of which they are composed an infinitesimally minute current of electricity, hence also of magnetism, is generated, still from the absurd manner in which the pieces of metal composing the ring are arranged, and which displays the most profound ignorance of the laws of electricity and magnetism, no trace of the minute current traverses the finger or toe on which the ring is worn; so that a wooden, any other ring, or none at all, would have exactly the same effect, as regards the magnetism or galvanism.]

SECRET POISON

Under this name are generally understood all poisons which can be administered imperceptibly, and which gradually shorten the life of man, like a lingering disease. They were not first discovered in the 17th century in France and Italy as many believe, but were known to the ancient Greeks and Romans, by whom they were used. I must however allow, that they were never prepared with more art at any period, or in any country, or employed oftener and with more success, than they were in these countries, and at that time. If it be true that they can be prepared in such a manner as to occasion death at a certain period previously determined, or that the person to whom they are given will die within a certain time limited, it must be confessed that the ancient poisoners have been far exceeded by the modern. But this advantage will be considered as scarcely possible, when one reflects upon the many variable circumstances which have an influence on the operation of medicines and poisons; and it has often happened that a company have swallowed the same poison, at the same time, and in the same quantity, some of whom have died sooner and some later, while some have survived. Thus died Pope Alexander VI. in the year 1503, and Cæsar Borgia recovered without any loss of health, though, by the bottles being changed through mistake, he drank of the poison that had been prepared for the other guests alone. At any rate, I am of opinion that the celebrated Tophania, when she engaged to free wives from disagreeable husbands within stated weeks and days, must have had certain and very accurate information respecting their constitution and manner of living, or, as the physicians say, their idiosyncrasy.

Some physicians have doubted respecting secret poison103; and others have only denied that its effects can with certainty be regulated to a fixed time104. I agree in opinion with the latter; but the former can be confuted by many examples both of ancient and modern times; for that the ancients were acquainted with this kind of poison, can be proved by the testimony of Plutarch, Quintilian, and other respectable authors. We are told by Plutarch, that a slow poison, which occasioned heat, a cough, spitting of blood, consumption, and a weakness of intellect, was administered to Aratus of Sicyon105; and Quintilian in his Declamations, speaks of this poison in such a manner as proves that it must then have been well known106. It cannot be said that such an invention was too great for that period, or that it required more knowledge of chemistry than any one possessed; for the Indians in America are acquainted with a most perfect poison of this kind, and can employ it with so much skill, that the person to whom it is given cannot guard against the treachery, even with the utmost precaution, but infallibly dies, though in a lingering manner, often after the expiration of some years107.

Theophrastus speaks of a poison which could be moderated in such a manner as to have effect in two or three months, or at the end of a year, or two years; and he remarks that the death, the more lingering it was, became the more miserable. This poison was prepared from aconitum, a plant which, on that account, people were forbidden to have in their possession, under pain of capital punishment108. He relates also, that Thrasyas had discovered a method of preparing from other plants a poison which, given in small doses of a drachm, occasioned an easy but certain death, without any pain, and which could be kept back for a long time without causing weakness or corruption. This Thrasyas, whose scholar Alexias carried the art still further, was a native of Mantinea, a city in Arcadia, and is celebrated by Theophrastus on account of his abilities, and particularly his knowledge of botany; but those are mistaken who ascribe to him the discovery of secret poison.

This poison was much used at Rome about two hundred years before the Christian æra. As several persons of distinction died the same year at that period, and of the like distemper, an inquiry being made into the cause, a maid-servant gave evidence against some ladies of the first families, who, she said, prepared and distributed poison; and above a hundred and fifty of them were convicted and punished109. As so many had learnt this destructive art, it could not be suppressed; and we find sufficient proofs in the Roman history that it was continually preserved. Sejanus caused such a secret poison to be administered by an eunuch to Drusus, who gradually declined afterwards, as by a consumptive disorder, and at length died110. Agrippina, being desirous of getting rid of Claudius, but not daring to despatch him suddenly, and yet wishing not to leave him sufficient time to make new regulations respecting the succession to the throne, made choice of a poison which should deprive him of his reason, and gradually consume him. This she caused to be prepared by an expert poisoner, named Locusta, who had been condemned to death for her infamous actions, but saved that she might be employed as a state engine. The poison was given to the emperor in a dish of mushrooms; but as, on account of his irregular manner of living, it did not produce the desired effect, it was assisted by some of a stronger nature111. This Locusta prepared also the poison with which Nero despatched Britannicus, the son of Agrippina, whom his father Claudius wished to succeed him on the throne. As this poison occasioned only a dysentery, and was too slow in its operation, the emperor compelled Locusta by blows, and by threatening her with death, to prepare in his presence one more powerful. It was first tried on a kid; but as the animal did not die till the end of five hours, she boiled it a little longer, until it instantaneously killed a pig to which it had been given, and this poison despatched Britannicus as soon as he had tasted it112. For this service the emperor pardoned Locusta, rewarded her liberally, and gave her pupils whom she was to instruct in her art, in order that it might not be lost.

The art of preparing this poison must have been well understood also at Carthage. When M. Attilius Regulus, the Roman general, who had been taken by the Carthaginians, was sent to Rome to propose to the senate that the Carthaginian prisoners might be restored in exchange for him, he prevented this negotiation, because he knew that a poison had been administered to him, by which the state would soon be deprived of his services. He returned, therefore, to Carthage, in compliance with the promise he had made to the enemy, who put him to death with the most exquisite torture113.

All these poisons were prepared from plants, particularly aconite, hemlock and poppy, or extracted from animal substances. Among those made from the latter, none is more remarkable than that supplied by the sea-hare, lepus marinus, with which, as Philostratus says114, Titus was despatched by Domitian. Without here attempting to define the substances employed by the ancients to compose their poisons, I shall only observe, that the lepus marinus, the terrible effects of which are expressly mentioned by Dioscorides, Galen, Nicander, Aëtius, Ælian115, Pliny116, and others, is that animal called at present in the Linnæan system Aplysia depilans117, as Rondelet conjectured, and has been since fully proved by Bohadsch118. This animal poison however seems to have been seldom used, as it easily betrays itself by some peculiar symptoms. It appears that it was not known to Aristotle, at least he makes no mention of it119. With the far stronger, and now common mineral poisons the ancients were not acquainted; for their arsenic was what we call orpiment, and not that pernicious metallic oxide which formed the principal ingredient of those secret poisons which in latter times were in France and Italy brought to a diabolical perfection120.

No one was ever more infamous by this art than Tophania, or Toffana, a woman who resided first at Palermo, and afterwards at Naples. She sold those drops, which from her acquired the name of aqua Tophania, aqua della Toffana, and which were called also acquetta di Napoli, or only acquetta; but she distributed her preparation by way of charity to such wives as wished to have other husbands. From four to six drops were sufficient to destroy a man; and it was asserted that the dose could be so proportioned as to operate in a certain time. As she was watched by the government, she fled to an ecclesiastical asylum; and when Keysler was at Naples in 1730, she was then still living, because no one could, or was willing to take away her life, while under that protection. At that time she was visited by many strangers out of curiosity.

In Labat’s Travels through Italy121 we also find some information which may serve still further to illustrate the history of Tophania. She distributed her poison in small glass phials, with this inscription, Manna of St. Nicholas of Bari, and ornamented with the image of the saint. A miraculous oil, employed by folly in the cure of many diseases, drops from the tomb of that saint which is shown at Bari in the kingdom of Naples; and on this account it is dispersed in great abundance under the like name. It was therefore the best appellation which Tophania could give to her poison, because the reputed sanctity of it prevented the custom-house officers from examining it too closely. When the viceroy was informed of this, which I think was in 1709, Tophania fled from one convent to another, but was at length seized and thrown into prison. The clergy raised a loud outcry on account of this violation of ecclesiastical freedom, and endeavoured to excite the people to insurrection. But they were soon appeased on a report being spread that Tophania had confessed she had poisoned all the springs in the city. Being put to the rack, she acknowledged her wickedness, and confessed to having caused the death of not less than 600 persons; named those who had protected her, who were immediately dragged from churches and monasteries; and declared that the day before she had absconded, she had sent two boxes of her manna to Rome, where it was found in the custom-house, but she did not accuse any one of having ordered it. She was afterwards strangled, and to mitigate the archbishop, her body was thrown at night into the area of the convent from which she had been taken. Tophania however was not the only person at Naples who understood the making of this poison; for Keysler says that at the time he was there it was still secretly prepared and much employed.

In the year 1659, under the government of Pope Alexander VII., it was observed at Rome that many young married women were left widows, and that many husbands died when they became disagreeable to their wives. Several of the clergy declared also, that for some time past various persons had acknowledged at confession that they had been guilty of poisoning. As the government employed the utmost vigilance to discover these poisoners, suspicion fell upon a society of young married women, whose president appeared to be an old woman who pretended to foretell future events, and who had often predicted very exactly many deaths to persons who had cause to wish for them. To ascertain the truth, a crafty female, given out to be a person of considerable distinction, was sent to this old woman, pretending that she wished to obtain her confidence, and to procure some of her drops for a cruel and tyrannical husband. The whole society were by this stratagem arrested; and all of them, except the fortune-teller, whose name was Hieronyma Spara, confessed before they were put to the torture. – “Where now,” cried she, “are the Roman princes, knights and barons, who on so many occasions promised me their protection! Where are the ladies who assured me of their friendship! Where are my children whom I have placed in so distinguished situations!” In order to deter others from committing the like crime, one Gratiosa, Spara’s assistant, three other women, and the obstinate Spara herself, who still entertained hopes of assistance till the last moment, were hanged in the presence of innumerable spectators. Some months after, several more women were executed in the same manner; some were whipt, and others were banished from the country. Notwithstanding these punishments, the effects of this inveterate wickedness have been from time to time remarked. Le Bret, to whom we are indebted for the above account, says122 that Spara was a Sicilian, and acquired her knowledge from Tophania at Palermo. If that be true, the latter must have been early initiated in villany, and must have become when very young a teacher of her infamous art. Keysler calls her a little old woman.
