Pescara.--Troth, I'll tell you, And briefly as I can, by what degrees They fell into this madness. Duke of Milan. The atrocious system of poisoning, by poisons so slow in their operation, as to make the victim appear, to ordinary observers, as if dying from a gradual decay of nature, has been practised in all ages. Those who are curious in the matter may refer to Beckmann on Secret Poisons, in his "History of Inventions," in which he has collected several instances of it from the Greek and Roman writers. Early in the sixteenth century the crime seems to have gradually increased, till, in the seventeenth, it spread over Europe like a pestilence. It was often exercised by pretended witches and sorcerers, and finally became a branch of education amongst all who laid any claim to magical and supernatural arts. In the twenty-first year of Henry VIII. an act was passed, rendering it high-treason: those found guilty of it, were to be boiled to death. One of the first in point of date, and hardly second to any in point of atrocity, is the murder by this means of Sir Thomas Overbury, which disgraced the court of James I, in the year 1613. A slight sketch of it will be a fitting introduction to the history of the poisoning mania, which was so prevalent in France and Italy fifty years later. Robert Kerr, a Scottish youth, was early taken notice of by James I, and loaded with honours, for no other reason that the world could ever discover than the beauty of his person. James, even in his own day, was suspected of being addicted to the most abominable of all offences, and the more we examine his history now, the stronger the suspicion becomes. However that may be, the handsome Kerr, lending his smooth cheek, even in public, to the disgusting kisses of his royal master, rose rapidly in favour. In the year 1613, he was made Lord High Treasurer of Scotland, and created an English peer, by the style and title of Viscount Rochester. Still further honours were in store for him.
