PREFACE

The material in this small volume was collectedin connexion with the Linacre Lecture at St.John’s College, Cambridge, and has beensomewhat expanded since its delivery on 6thMay 1922. The introduction is chiefly oflocal interest in connexion with the history ofthe Linacre Lecture. Without attempting acomplete account of old age and its diseases Ihave passed in review some ancient and modernmedical aspects of this subject, but, except forincidental references, medical treatment has notbeen considered.

For ready help, especially as regards theillustrations, my cordial thanks are due toC. J. S. Thompson, Esq., M.B.E., of theWellcome Historical Museum, and for theindex I am much indebted to H. M. Barlow,Esq., Assistant Librarian of the Royal Collegeof Physicians of London.
