species of strychnos and other plants, while the Malays and hill tribes of India use aconite, and other poisonous juices and extracts. The Antiaris toxicaria is also used as an arrow poison by the Malays.

The bushmen of the South African district "Kalahari," use the juice of the leaf beetle "diamphidia" and its larva for poisoning their arrow-heads. Lewin, who calls the beetle Diamphidia simplex, found in its body, besides inert fatty acids, a toxalbumin which causes paralysis, and finally death. According to Boehm, the poison from the larva also belongs to the toxalbumins, and Starke states, that it causes the dissolution of the colouring matter of the blood and produces inflammation.

A halo of mystery, sometimes intermixed with romance, has hung about the dread word poison from very early times. In the dark days of mythology, allusions to mysterious poisons were made in legend and saga. Thus a country in the Far North was supposed to be ruled and dominated by sorcerers and kindred beings, all of whom were said to be children of the Sun. Here dwelt Æëtes, Perses, Hecate, Medea, and Circe. Hecate was the daughter of Perses and married to Æëtes, and their daughters were Medea and Circe. Æëtes and Perses were said to be brothers, and their country was afterwards supposed to be Colchis. To Hecate is ascribed the foundation of sorcery and the discovery of poisonous herbs. Her knowledge of magic and spells was supposed to be unequalled. She transmitted her power to Medea, whose wonderful exploits have been frequently described and depicted, and who by her magic arts subdued the dragon that guarded the golden fleece, and assisted Jason to perform his famous deeds. Hecate's garden is described by the poets as being enclosed in lofty walls with thrice-folding doors of ebony, which were guarded by terrible forms, and only those who bore the leavened rod of expiation and the concealed conciliatory offering could enter. Towering above was the temple of the dread sorceress, where the ghastly sacrifices were offered and all kinds of horrible spells worked.

Medea was also learned in sorcery and an accomplished magician. It is related that, after her adventures with Jason, she returned with him to Thessaly. On their arrival they found Æson, the father of Jason, and Pelias, his uncle, who had usurped the throne, both old and decrepit. Medea was requested to exert her magical powers to make the old man young again, an operation she is said to have speedily performed by infusing the juice of certain potent plants into his veins.

Some years after, Medea deserted Jason and fled to Athens, and shortly afterwards married Ægeus, king of that city. Ægeus had a son by a former wife, named Theseus, who had been brought up in exile. At length he resolved to return and claim his parentage, but Medea hearing of this, and for some reason greatly resenting it, put a poisoned goblet into the hands of Ægeus at an entertainment he gave to Theseus, with the intent that he should hand it to his son. At the critical moment, however, the king cast his eyes on the sword of Theseus, and at once recognized it as that which he had delivered to his son when a child, and had directed that it should be brought by him when a man, as a token of the mystery of his birth. The goblet was at once thrown away, the father embraced his son, and Medea fled from Athens in a chariot drawn by dragons through the air.

Circe's charms were of a more seductive and romantic character. She is said to have been endowed with exquisite beauty, which she employed to allure travellers to her territory. On their landing, she entreated and enticed them to drink from her enchanted cup. But no sooner was the draught swallowed, than the unfortunate stranger was turned into a hog, and driven by the magician to her sty, where he still retained the consciousness of what he had been, and lived to repent his folly.

Gula, the patroness of medicine and a divinity of the Accadians, was regarded by that ancient people as "the mistress and controller of noxious poisons" as far back as 5000 years B.C.

According to some authorities, the Hebrew word Chasaph, translated in the Old Testament Scriptures as witch, meant poisoner. Scott states the witches of Scripture had probably some resemblance to those of ancient Europe, who, although their skill and power might be safely despised as long as they confined themselves to their charms and spells, were very apt to eke out their capacity for mischief by the use of actual poison; so that the epithet of sorceress and poisoner were almost synonymous.

The oldest Egyptian king, Menes, and Attalus Phylometer, the last king of Pergamus, were both learned in the knowledge of the properties of plants. The latter monarch also knew something of their medicinal uses, and was acquainted with henbane, aconite, hemlock, hellebore, etc. Other Egyptian rulers cultivated the art of medicine, and there is little doubt that, probably through the priests, who were the chief practitioners of the art of healing, they gathered a considerable knowledge of the properties of many poisonous and other herbs. Prussic acid was known to the Egyptians, and prepared by them in a diluted form, from the peach and other plants. It is highly probable, indeed, that the priests had some rudimentary knowledge of the process of distillation, and prepared this deadly liquid from peach leaves or stones, by that method. The "penalty of the peach" is alluded to in a papyrus now preserved in the Louvre, which points to the liquid being used as a death draught.

The ancient Greeks, like the Chinese of to-day, looked upon suicide, under certain conditions, as a noble act, for which poison was the usual medium. Their "death cup" was mainly composed of the juice or extract of a species of hemlock, called by them cicuta. The Chinese, from remote times, are supposed to have used gold as a poison, especially for suicidal purposes, and at the present day, when a high official or other individual puts an end to his life, it is always officially announced, "He has taken gold leaf"; a curious phrase, which probably has its origin in antiquity.

Nicander, of Colophon, a Greek physician, who lived 204-138 B.C., in his work on "Poisons and their Antidotes," the earliest on the subject known, describes the effects of snake venom and the properties of opium, henbane, colchicum, cantharides, hemlock, aconite, toxicum (probably the venom of the toad), buprestis, the salamander, the sea-hare, the leech, yew (decomposed), bull's blood, milk, and certain fungi, which he terms "evil fermentations of the earth"; and as antidotes for the same he mentions lukewarm oil, warm water, and mallow or linseed tea to excite vomiting. The same writer also made a rough classification of the poisons known in his time, twenty-two in all, and divided them into two classes—viz., "those which killed quickly," and "those which killed slowly."

Of the minerals, arsenic, antimony, mercury, gold, silver, copper, and lead were used by the Greeks; the antidote recommended in case of poisoning being hot oil, and other methods to induce vomiting and prevent the poison being absorbed into the system.

Bull's blood is classed as a poison by various ancient writers, and it is recorded that Æson, Midas King of Phrygia, Plutarch, and Themistocles, killed themselves by drinking bull's blood. It is probable that some strong poisonous vegetable substance, such as cicuta, was mixed with the blood.

Dioscorides throws a further light on the poisons of antiquity in his great work on Materia Medica, which for fifteen centuries or more remained the chief authority on that subject. He mentions cantharides, copper, mercury, lead, and arsenic. Among the animal poisons are included toads,
