Ferdinand II., Grand Duke of Tuscany, was also, it appears, the slave of his infirmities. He was often seen walking up and down his apartment between two large thermometers, at which he anxiously and continually glanced, putting on skull caps, of which he had five or six in his hand, according to the degree of cold or heat that the instrument pointed toward. So,43too, with the Abbe de St. Martin, who, in the seventeenth century, was so notorious for his monomania. He had always nine skull caps on his head to keep him from the cold; and on the top of those he put a wig, which, of course, was never by any chance in its proper position. More than this, he wore nine pairs of stockings, one over the other; his bed was of brick, under which there was a furnace, where he made a fire in order to obtain just that amount of warmth that he desired. The Jesuit Ghezzi wore seven caps under his wig. Fourier, the mathematician, who had returned from Egypt nearly dead with rheumatism, suffered severely when he found himself in a temperature below 20° Réaumur; and a servant followed him about everywhere, in readiness to offer him additional coats and wrappings. During the latter years of his life, when rendered hors de combat by the asthma, from which he had suffered since his youth, he lived almost entirely in a kind of box, which allowed no deviation of the body, and allowed nothing to pass except his head and arms.—Shilling Magazine.
