PREFACE TO THE SECOND EDITION 



CONCENTRATION, sequence, and election are 

 fruitful principles in the higher education. 



In 1898 the Committee on Medical Education, 

 appointed by the Harvard Faculty of Medicine, 

 reported in favor of the " concentration " system 

 urged in the committee by the author in com- 

 mon with Professor W. T. Councilman. By this 

 method, the first half-year in the Medical School 

 is devoted to anatomy and histology, the second 

 half-year to physiology and biological chemistry, 

 the third half-year to pathology and bacteriology, 

 and the fourth, fifth, and sixth half-years to 

 practical medicine and surgery. Work under 

 the new system began in the collegiate year of 

 1899-1900. In 1904, largely through the influ- 

 ence of Professor Bowditch, the seventh and 

 eighth half-years were made elective, each stu- 

 dent choosing for himself the studies best suited 

 to his needs. 



Concentration provides that the student shall 

 not serve two masters, but shall study at one
