did little or nothing to develop anatomy save to issue suc- 

 cessive editions of his ''Fabrica." Three years before 

 his death there appeared from the press at Madrid his 

 edition of Fallopio 's anatomy. 



Albrecht von Haller, Swiss anatomist, physiologist, 

 poet, botanist and administrator, deserves to be regarded 

 as the most precocious and one of the most productive of 

 all the men who have contributed to the advancement of 

 anatomy. At the early age of eight he is said to have 

 compiled a biographical index of over 2,000 eminent men 

 and women. This prodigious activity he continued for 

 the next sixty years, and it is stated that he conducted a 

 monthly scientific journal to which he himself contributed 

 12,000 articles on nearly every phase of human knowl- 

 edge. Nor were his contributions superficial, for Sir 

 William Turner says that his anatomical descriptions 

 and his beautiful and accurate figures were the most val- 

 uable which had appeared up to that time (1746-51). A 

 list of his medical writings alone fills eleven octavo 

 pages of closely printed type. Late in life he returned to 

 Berne from Gottingen, where from 1736-1753 he had held 

 the position as professor of anatomy, physiology, surgery 

 and botany, to engage in his native land in municipal ad- 

 ministration. 



Johannes Mueller, who, in the first half of the last cen- 

 tury, became famed as an anatomist, zoologist, and physi- 

 ologist, became, at the age of twenty-five, professor ex- 

 traordinary of physiology at the University of Bonn. He 

 began an early career of prodigious activity, which he 

 continued for thirty-three years. 



Avicenna at the age of seventeen was regarded as an 

 excellent physician. At twenty-one he was the author of 

 several treatises. He was called "The Prince of Arabian 

 physicians" by his contemporaries. 



Bernhard Siegfried Albinus (1697-1770), for fifty 

 years a teacher at the University of Leyden, was called to 

 the University at the age of twenty-one, from Paris, 

 whither he had gone on the advice of his father, to study
