(From a Painting after Robert Hannah.) 



William Harvey, 1578-1637, a graduate of Cambridge, who studied under Fabricius.the great anatomist of 

 Padua, He demonstrated about 1616 that the blood passes through the body in a " kind of circle"; but he did

 knowledge, and he made important observations on the development of the chick.
