Harvey has the rare distinction of standing at the head of three departments of science in England—comparative anatomy, physiology, and medicine. When these scarcely existed, he evolved them into living form from chaos. The extent of his achievements must be gauged by the extent of the superstructure built upon his foundations. He laid the foundations broad and firm, and practised the true method of science. Notwithstanding Harvey’s infirmities, his mind in old age was characterised by an abiding youthfulness and desire to learn, so that Aubrey found him studying Oughtred’s “Clavis Mathematica,” and working problems not long before he died. He was equally pleased to communicate his knowledge to others, and, as Aubrey relates, “to instruct any that were modest and respectful to him. In order to my journey (I was at that time bound for Italy), he dictated to me what to see, what company to keep, what books to read, how to manage my studies—in short, he bid me go to the fountain-head and read Aristotle, Cicero, Avicenna.” He was always very contemplative, and was wont to frequent the leads of Cockaine House, which his brother Eliab had bought, having there his several stations in regard to the sun and the wind, for the indulgence of his fancy. At the house at Combe, in Surrey, he had caves made in the ground, in which he delighted in the summer-time to meditate. He also loved darkness, as he could then best contemplate. The activity of his mind would often deprive him of sleep, when he would rise and walk about in his shirt, until he was cooled and could gain sleep. Similarly he treated his attacks of gout; he would sit with his legs bare, even in frost, on the leads of Cockaine House, and put them into a pail of water until he was almost dead with cold, and thus he found his attacks could be moderated. His great works were, according to the custom of the age, written in Latin; and Dr. Willis, who has translated all of them into English, describes his Latin as generally easy, often elegant, and not unfrequently copious and imaginative—he never seems to feel in the least fettered by the language he is using. The College of Physicians, says Dr. Munk, possesses some interesting memorials of Harvey, two of which may be mentioned. One the whalebone probe or rod, tipped with silver, with which he demonstrated the parts in his Lumleian Lectures at the college. The other, consisting of six tables of wood, upon which are spread the different blood-vessels and nerves of the human body, carefully dissected out, probably prepared by Harvey himself, and presumed to have been used by him in his lectures. They were presented to the college by the Earl of Winchelsea, one of whose ancestors, the Lord-Chancellor Nottingham, had married the niece of Harvey. FOOTNOTES: [4] Restitutio Christianismi.
