THE 

 WILLIAMS MEMORIAL PUBLICATION 



FUND 



The present volume is the ninth work pub- 

 lished by the Yale University Press on the Wil- 

 liams Memorial Publication Fund. This Foun- 

 dation was established June 15, 19 16, by a gift 

 made to Yale University by George C. F. Wil- 

 liams, M.D., of Hartford, a member of the 

 Class of 1878, Yale School of Medicine, where 

 three generations of his family studied — his 

 father, William Cook Williams, M.D., in the 

 Class of 1850, and his grandfather, William 

 Chauncey Williams, M.D., in the Class of 

 1822.
