anatomists of the sixteenth century, says that Fabrieius appears "not 

 to have had even the most remote idea of a circulation of the blood." 

 If Fabrieius had not, who had ? 



JULIUS CASSERIUS. 



1545-1605. 



CASSERIUS was sometimes called Placentinus, from the place 

 of his birth. By Douglas he is described as " philosophus, 

 medicus, chirurgus et anatomicus pereximius." Born of 

 humble, not to say poor, parents, he became the famulus of Fabrieius 

 at Padua; from famulus, auditor, and, from auditor, disc/put us, until 

 he became a Professor in the University of Padua, at the time 

 of Harvey. He has a certain quaint, not to say picturesque, way 

 of setting forth his views of structure, that one would have liked to 

 illustrate more fully. His work contains excellent figures of the 

 organs of sense in many animals. 



WILLIAM HARVEY. 



!57 8 - l6 57- 



HARVEY was born at Folkestone on April 1st, 1578 — 

 eighteen years after Lord Bacon, one year after Van 

 Helmont, and just four years after the publication by 

 Fabrieius of his work on the Ostiola. Proceeding to Cambridge he 

 took his degree in Arts in 1597. In those days Padua was one of 

 the great centres of intellectual activity, and its medical school was 

 famous. Harvey proceeded to Padua, studied under Fabrieius, 

 and took his degree of Doctor of Medicine there in 1602 — which 

 entitled him " to practise and to teach arts and medicine in every land 

 and seat of learning." On his return to England he was incorporated 

 as an M.D. in Cambridge, became a member of the Royal College of 

 Physicians in 1604, and a fellow in 1607. He was appointed physician 

 to St. Bartholomew's Hospital in 1609. At the age of thirty-seven 

 he was appointed, in 1615, by the College of Physicians, Lecturer on 

 Anatomy, i.e. to the lectureship founded by Drs. Lumley and Caldwell. 

 In 1616 he enunciated his views on the movements of the heart and 

 of the blood. It was not, however, until 1628 that he published his 

 famous work, Exercitatio Anatomica de Motu Cordis et Sanguinis in 

 Animalibus, or An Anatomical Disquisition on the Motion of the Heart 

 and Blood in Animals. It is a small quarto of about 80 pages, and
