The secret was also communicated by Sir Kenelm to Mayerne, through whom it was imparted to the Duke of Mayerne--"a long time his friend and protector." After the Duke's death, his surgeon communicated it to divers people of quality; so that, ere long, every country-barber was familiar with the discovery. The mention made of Mayerne in the lecture is interesting, as it settles a point on which Dr. Aikin had no information; viz.,--Whether Sir Theodore's Barony of Aubonne was hereditary or acquired? Sir Kenelm says, "A little while after the Doctor went to France, to see some fair territories that he had purchased near Geneva, which was the Barony of Aubonne." For a time the Sympathetic Powder was very generally believed in; and it doubtless did as much good as harm, by inducing people to throw from their wounds the abominable messes of grease and irritants which were then honoured with the name of plaisters. "What is this?" asked Abernethy, when about to examine a patient with a pulsating tumour, that was pretty clearly an aneurism. "Oh! that is a plaister," said the family doctor. "Pooh!" said Abernethy, taking it off, and pitching it aside. "That was all very well," said the physician, on describing the occurrence; "but that 'pooh' took several guineas out of my pocket." Fashionable as the Sympathetic Powder was for several years, it fell into complete disrepute in this country before the death of Sir Kenelm. Hartman, the Knight's attached servant, could, of his own experience, say nothing more for it than, when dissolved in water, it was a useful astringent lotion in cases of bleeding from the nose; but he mentions a certain "Mr. Smith, in the city of Augusta, in Germany, who told me that he had a great respect for Sir D. K.'s books, and that he made his sympatheticall powder every year, and did all his chiefest cures with it in green wounds, with much greater ease to the patient than if he had used ointments or plaisters." In 1643 Sir Kenelm Digby was released from the confinement to which he had been subjected by the Parliament. The condition of his liberty was that he forthwith retired to the Continent--having previously pledged his word as a Christian and a gentleman, in no way to act or plot against the Parliament. In France he became a celebrity of the highest order. Returning to England with the Restoration, he resided in "the last fair house westward in the north portico of Covent Garden," and became the centre of literary and scientific society. He was appointed a member of the council of the Royal Society, on the incorporation of that learned body in the year 1663. His death occurred in his sixty-second year, on the 11th of June, 1665; and his funeral took place in Christ's Church, within Newgate, where, several years before, he had raised a splendid tomb to the memory of the lovely and abandoned Venetia. His epitaph, by the pen of R. Ferrar, is concise, and not too eulogistic for a monumental inscription:--
