Bartholinus began with the study of theology, andfor nine years lived at other Universities. He graduated at Baselin K345 under Bauhin, and in 1648 became Professor in Paulli being induced for a consideration to resign his Chair to giveplace to the younger Bartholinus. Among his pupils was JOH. WALvEUS (b. 1604), Professor inLeyden, 1633, who wrote two epistles On the Motion of the Clti/leand Blond, to T. B., son of Caspar B. They show how he hadgrasped the importance of Harveys doctrine, and he gives thefollowing experiment, entitled Dissection of a Vein in LivingCreatures, in support thereof. The woodcut explains the femoral vein is constricted by the thread passed roundit the blood flows out, not in guttce or drops, but as a rmulussanguinis qui, inferiori vena? parte vulnerata, contivuo exilit.

Harveys work, supplemented with the discovery of the capillariesand that of the lymphatic system, marks a new era in physiology. Itrevolutionized the whole subject, for now the examination of theexchanges between the blood of the organs and tissues of the bodybecame possible. The idea of spirits ought to have disappeared,but it did not. The very title of his work suggests the wide viewHarvey took of the problem ; Harvey made accurate anatomicalobservations and planned experiments to test his hypotheses, and hemade-abundant use
