Sir Kenelm's "Observations upon Religio Medici," are properly characterized by Coleridge as those of a pedant. They were written whilst he was kept a prisoner, by order of the Parliament, in Winchester House; and the author had the ludicrous folly to assert that he both read the "Religio Medici" through for the first time, and wrote his bulky criticism upon it, in less than twenty-four hours. Of all the claims that have been advanced by authors for the reputation of being rapid workmen, this is perhaps the most audacious. For not only was the task one that at least would require a month, but the impudent assertion that it was accomplished in less than a day and night was contradicted by the title-page, in which "the observations" are described as "occasionally written." Beckford's vanity induced him to boast that "Vathek" was composed at one sitting of two days and three nights; but this statement--outrageous falsehood though it be--was sober truth compared with Sir Kenelm's brag. But of all Sir Kenelm's vagaries, his Sympathetic Powder was the drollest. The composition, revealed after the Knight's death by his chemist and steward, George Hartman, was effected in the following manner:--English vitriol was dissolved in warm water; this solution was filtered, and then evaporated till a thin scum appeared on the surface. It was then left undisturbed and closely covered in a cool place for two or three days, when fair, green, and large crystals were evolved. "Spread these crystals," continues the chemist, "abroad in a large flat earthen dish, and expose them to the heat of the sun in the dog-days, turning them often, and the sun will calcine them white; when you see them all white without, beat them grossly, and expose them again to the sun, securing them from the rain; when they are well calcined, powder them finely, and expose this powder again to the sun, turning and stirring it often. Continue this until it be reduced to a white powder, which put up in a glass, and tye it up close, and keep it in a dry place." The virtues of this powder were unfolded by Sir Kenelm, in a French oration delivered to "a solemn assembly of Nobles and Learned Men at Montpellier, in France." It cured wounds in the following manner:--If any piece of a wounded person's apparel, having on it the stain of blood that had proceeded from the wound, was dipped in water holding in solution some of this sympathetic powder, the wound of the injured person would forthwith commence a healing process. It mattered not how far distant the sufferer was from the scene of operation. Sir Kenelm gravely related the case of his friend Mr. James Howel, the author of the "Dendrologia," translated into French by Mons. Baudoin. Coming accidentally on two of his friends whilst they were fighting a duel with swords, Howel endeavoured to separate them by grasping hold of their weapons. The result of this interference was to show the perils that
