Harvey became Treasurer of the College of Physicians in 1628, but resigned this office and also procured the appointment of a deputy at St. Bartholomew’s Hospital in 1630, when he was commanded by the King to attend the young Duke of Lennox in his travels on the Continent. Having returned from this expedition, in 1632 he was sworn in Physician in Ordinary for his Majesty’s household, and in 1639 we find a letter in the Lord Steward’s office, giving orders for settling a diet of three dishes of meat a meal with all incidents thereunto belonging upon Dr. Harvey. But later on, in 1640, the King when at York makes another arrangement, devoting £200 a year to Dr. Harvey, the three dishes of meat probably not having been readily forthcoming just then. In 1632-3 a deputy had again to be appointed at St. Bartholomew’s; in 1636 he was required to accompany the Earl of Arundel on his embassy to the Emperor of Germany. This gave him an opportunity of personally explaining the circulation to various eminent physicians in the principal German cities. On one of these occasions, at Nuremberg, we find it recorded that Harvey gave a public demonstration of the circulation, which satisfied all except Caspar Hofmann.[8] Returning to England, Harvey accompanied Charles I. in his expeditions, such as that to Scotland in 1639; and we may remark that, being in such close proximity to the royal person, he contrived very skilfully not to become involved in court intrigues, his best protection being his devotion to his medical and physiological investigations.[9] Even when war had broken out, Harvey became in no way obnoxious to the Parliament, for he tells us himself that he attended the King not only with the consent but by the desire of Parliament. In this way Harvey was present on the very field at the battle of Edgehill. “During the fight,” says Aubrey, “the Prince and Duke of York were committed to his care. He told me that he withdrew with them under a hedge, and took out of his pocket a book and read. But he had not read very long before a bullet of a great gun grazed on the ground near him, which made him remove his station.” We cannot but admire the coolness and serenity of mind which could thus occupy itself with reading in the midst of carnage, having evidently no sort of belief in, or vocation for, the employment of force in the arbitrament between opposing opinions. Accompanying Charles to Oxford, he found congenial society, and was incorporated Doctor of Medicine on the 7th December, 1642. “I first saw him at Oxford,” says Aubrey, “1642, after Edgehill fight; but was then too young to be acquainted with so great a doctor. I remember he came several times to our college (Trinity) to George Bathurst, B.D., who had a hen to hatch eggs in his chamber, which they opened daily to see the progress and way of generation.”
