СКАЧАТЬ the skin of a species of toad secretes a poison, similar in action to digitalis.

      The venom of the toad has had the reputation of possessing poisonous properties from a very early period, and was probably one of the earliest forms of animal poison known.

      The old tradition, that King John was poisoned by a Friar who dropped a toad into his wine, was regarded as a ridiculous fable until some years ago, when it was discovered that the skin of the toad secretes a body, the active principle of which, "phrynin," is a poison of considerable power.

      One of the most curious uses to which the toad has been put is recorded on a medical diploma now in the Library of Ferrara, which was granted to one Generoso Marini in 1642. Marini having made application for a Ferrarese diploma in medicine, the judges in whom the power of granting such degrees was invested, ordered him to exhibit some efficient proofs of his capability to practise the medical art.

      Marini at once agreed to comply with their demand, and the result is recorded in his diploma, which was discovered by Cittadella in the archives of Ferrara, and is translated as follows:—

"Having publicly examined and approved the science and knowledge of medicine of Signor Generoso Marini, and his possession of the wonderful secret called 'Orvietano,' which he exhibited on the stage built in the centre of this our city of Ferrara, in presence of its entire population so remarkable for their civilization and learning, and in presence of many foreigners and other classes of people, we hereby certify that, also in our presence, as well as that of the city authorities, he took several living toads, not those of his own providing, but from a great number of toads which had been caught in fields in the locality by persons who were strangers to him, and which were only handed to him at the moment of making the experiment. An officer of the court then selected from the number of toads collected, five of the largest, which the said Generoso Marini placed on a bench before him, and in presence of all assembled spectators, he, with a large knife, cut all the said toads in half. Then, taking a drinking cup, he took in each hand one half of a dead toad, and squeezed from it all the juices and fluids it contained into the cup, and the same he did with the remainder. After mixing the contents together, he swallowed the whole, and then placing the cup on the bench he advanced to the edge of the stage, where for some minutes he remained stationary. Then he became pale as death and his limbs trembled, and his body began to swell in a frightful and terrible manner; and all the spectators began to believe that he would never recover from the poison he had swallowed, and that his death was certain. Suddenly, taking from a jar by his side some of his celebrated 'Orvietano,' he placed a portion of it in his mouth and swallowed it. Instantly, the effect of this wonderful medicine was to make him vomit the poison he had taken, and he stood before the spectators in the full enjoyment of health.[1]

      "The populace applauded him highly for the indisputable proof he had given of his talent, and he then invited many of the most learned of those present to accompany him to his house, and he there showed them his dispensary as well as his collection of antidotes, and among them a powder made from little vipers, a powerful remedy for curing every sort of fever, as he had proved by different experiments he had made on people of quality and virtue, all of whom he had cured of the fever from which they were suffering, etc.

      "In consequence of the rare talent exhibited by Signor Generoso Marini, and as a proof of our love and respect for his wisdom, we have resolved by the authority placed in our hands publicly to reward him with a diploma, so that he may be universally recognized, applauded, and respected. In witness thereof we have set our hands and the public seal of the municipality of Ferrara.

      But although the toad under certain conditions was credited with poisonous properties, during the Middle Ages it was esteemed a valuable remedy for the plague, and was employed for that purpose in Austria as late as the year 1712.

      Cantharides, or Spanish fly, was very commonly used as a poison in mediæval times, the usual method of administering being to chop it up and mix it with pepper. It is said to have been the first poison tried on the unfortunate Sir Thomas Overbury, although his murderers finally finished him off with corrosive sublimate. Poisoned rings are said to have been the invention of the Italians, who fashioned rings in which the poison was inserted in a receptacle where the jewel is usually set. Attached to the inner part of the ring was a sharp point which, when the hand of the wearer was grasped, scratched the flesh and injected the poison. Rings were also used for carrying strong poisons secretly—such as arsenic, or corrosive sublimate—and in this manner many were enabled to commit suicide after being imprisoned.

      Hyoscyamus, commonly called henbane, is a herb which has been employed from remote times. Benedictus Crispus, Archbishop of Milan, in a work written shortly before A.D. 681, alludes to it under the name of hyoscyamus and symphoniaca, and in the tenth century its virtues are particularly recorded by Macer Floridus. In the early Anglo-Saxon works it is called henbell and sometimes belene. In a French herbal of the fifteenth century it is called hanibane or hanebane. From a very early period it has been employed as a sedative and anodyne, for producing sleep, although simple hallucinations sometimes accompany its use.

      An old tradition states, that once in the refectory of an ancient monastery the monks were served with henbane, instead of some harmless root, in error by the cook. After partaking of the dish, they were seized with the most extraordinary hallucinations. At midnight one monk sounded the bell for matins, while others walked in the chapel and opened their books, but could not read. Others sang roystering drinking songs and performed mountebank antics, which convulsed the others with uncontrollable laughter, and the pious monastery for the nonce was turned into an asylum. Certain stones which were sold for large sums of money were supposed to change colour when brought near a poisonous substance, and they were consequently much sought after by high personages. The horn of the unicorn was said to become moist when placed near poisoned food. Bickman records his belief that several slow poisons were known to the ancients which cannot now be identified. The Carthaginians also seem to have been acquainted with similar poisons, and, according to tradition, administered some to Regulus, the Roman general. But we cannot endorse Bickman's belief.

      An incident which happened to the army led by Mark Antony against the Parthians, and described by Plutarch, is said to have been caused by aconite. At one time during the expedition, "the soldiers being very short of provisions, sought for roots and pot-herbs … and met one that brought on madness and death. The eater immediately lost all memory and knowledge, busying himself at the same time in turning and moving every stone he met with, as if he were on some important pursuit. The camp was full of unhappy men stooping to the ground, and digging up and removing stones, till at last they were carried off by bilious vomiting. … Whole numbers perished, and the Parthians still continued to harass them. Antony is said to have frequently exclaimed: 'Oh! the ten thousand!' alluding to the army which Xenophon led in retreat; both a longer way and through more numerous conflicts, and yet led in safety."

      Nine active or virulent poisons are mentioned by most ancient writers on Indian medicine, many of which are at present not identified. Most of them are apparently varieties of aconite. Besides these, they employed opium, gunja, datura, roots of Nerium odorum and Gloriosa superba, the milky juices of Calotropis gigantea and Euphorbia neriifolia, white arsenic, orpiment, and the poison extracted from the fangs of serpents.

      Most of the older Sanscrit MSS. are written on paper prepared with orpiment to preserve them from the ravages of insects. Three varieties of Datura yield atropine, a powerful poison. These СКАЧАТЬ
