INTRODUCTION. 37 



Galen's errors in Anatomy, in the same proportion did his 

 veneration for that great man diminish, and this he did 

 not fail openly to avow and publish. Immediately he had 

 a host of enemies to encounter, and so hot was the opposi- 

 tion, that he was obliged to leave Paris. His criticisms on 

 Galen were published when he was only 28 years of age, 

 in consequence of which daring and impious opposition, as 

 it was supposed, to the infallible Galen, all Europe seemed 

 in arms against Yesalius. And what was most trying, his 

 Preceptor, Sylvius , at Paris, was the most bitter among 

 his opponents. Sylvius changed the name of Yesalius to 

 that of Vesanu or madman. In defiance of all opposition, 

 however, his reputation increased, and he was appointed 

 Professor of Anatomy in the University of Padua, by the 

 Eepublic of Venice, which chair he filled for seven years. 

 He was also first Physician to the Emperor, Charles Y, who 

 kept him constantly at court. 



Vesalius' work, "De structura corporis Humani" is said to 

 have been published when he was but about 25 years of age. 

 In 1561,, Gabriel Fallopius, a pupil of Vesalius, distinguished 

 himself. He was Professor of Anatomy in the University 

 of Padua, and also author of an anatomical treatise under 

 the title of " Observations Anatomicce" 



It was intended more as a supplement to the work of 

 Vesalius, many of whose descriptions he corrects, which 

 Vesalius it seems did not much like, and in consequence 

 replied to his pupil. 



In 1563, Bartliolomcms Eustachius published at Venice a 

 work called " Opuscula Anatomicce" which is highly spoken 

 of. He is distinguished for his Anatomical pursuits and 

 discoveries. 



The Ifah century opens with the brilliant discovery of the 

 circulation of the blood, by Dr. Wm. Harvey, in 1628. 



The previous discoveries of Fabricius on the valves in the 

 veins and those of Servitus, Columbus and Caesalpinus, on 

 the circulation through the lungs, were very important links 

 to Harvey in making his immortal discovery. He met with
