1615

Harvey appointed Lumleian Lecturer of London College of Physicians (Chauvois, 96, 98), a position established in 1581 and held for life (100-102). His notes for the visceral lectures of April 1616 record his discovery of blood circulation (106). Cf. Craddock : “He [Harvey] lectured about and demonstrated, the circulation of the blood from about 1615, and in 1624 published his discovery in Latin. Then in 1628 it came out in English. When Harvey likened the heart and circulatory system to a pump and the vena cava to ‘the cellar and cistern of the blood,’ he dragged the body out of an agricultural frame and into a mechanical one (Craddock, 53).
