Harvey’s acquaintance with the literature of medicine enabled him to cite apposite examples, and must evidently have been of the greatest service to him in elucidating his problems. Hunter too often traversed paths which were already well trodden, for his defective education prevented him from knowing the works of his predecessors. The atmosphere of Courts and of the refined and learned society in which Harvey spent most of his life has given a polish to his writings and a gentleness to his character which were wholly wanting to John Hunter, upon whom the res angustae domi—absent in Harvey’s case—had impressed a certain ruggedness of character, but in both there was a native strength and robustness of constitution which render them not dissimilar.
As mere practitioners or curers of the body neither Harvey nor Hunter were highly esteemed by their contemporaries, though both made considerable sums of money by their art. The curiosity both of Harvey and of Hunter was boundless, but their minds were of the creative rather than of the imaginative type. Both collected facts and were averse to theories.
Neither Hunter nor Harvey were religious men in the ordinary and narrow sense of the term. Harvey, living at an intensely religious period in the history of England, appears to have held the broad views befitting a student of nature. An eminently religious tone runs throughout his work, “a devout and reverential recognition of God,” as Sir Russell Reynolds expressed it, “not only as the great primal ever-acting force, behind, outside and before all the works of Nature; but as the Being, ‘the Almighty and Eternal God,’ to whom he says in his last will and testament, ‘I do most humbly render my soul to Him who gave it; and to my blessed Lord and Saviour Christ Jesus.’” Hunter living in a freer age had yet the remains of his Scottish upbringing adherent to the last.
CHAPTER VIII
Harvey’s Anatomical Works
Harvey’s liber aureus is certainly his “Exercitatio anatomica de motu cordis et sanguinis in animalibus.” [An Anatomical Treatise on the Movement of the Heart and Blood in Animals, by William Harvey, the Englishman, Physician to the King and Professor of Anatomy in the London College of Physicians.] The work was issued from the press of William Fitzer, of Frankfort, in the year 1621. Harvey chose Frankfort as the place of publication for his book because the annual book fair held in the town enabled a knowledge of his work to be more rapidly spread than if it had been issued in England.
The book contains the matured account of the circulation of the blood, of which somewhat more than the germ had appeared in the notes of the Lumleian visceral lecture for 1616. It is a small quarto, containing seventy-two pages and a page and half of errata, for Harvey wrote a villainous hand, and communication between Germany and England was too slow, expensive, and uncertain to allow an author to correct his book sheet by sheet as it issued from the press.
The Treatise opens with a dedication to Charles I. couched in fitting emblematical language, and signed “Your Most August Majesty’s Most Devoted Servant, William Harvey.” The dedication is followed by a preface addressed to “Dr. Argent [then President of the College of Physicians, and one of Harvey’s intimate friends] as well as to the other learned physicians, his most esteemed colleagues.” In this preface he excuses himself for the book, saying that he had already and repeatedly presented to them his new views of the movement and function of the heart in his anatomical lectures. And that he had now for nine years and more confirmed these views by multiplied demonstrations in their presence. He had illustrated them by arguments and he had freed them from objections of the most learned and skilful Anatomists. He then proceeds so modestly that it is difficult to realise how great an innovation he was really making when he says, “I profess both to learn and to teach anatomy, not from books but from dissections, not from the positions of philosophers but from the fabric of nature.”
