WALTER MERCER BIRTHDAY VOLUME Teaching the undergraduate is an art in itself. It requires cultivation, and the first class teacher somehow manages to spice his routine lectures and demonstrations with what is new and stimulating. Men of the sort described here were loyal to their teaching institutions and promoted their welfare. That some of them were national and international figures-for orthopaedic surgeons Robert Jones is the supreme exemplar-is in the context of this book incidental. But those who were not widely known except as teachers deserve to be remembered too; and for those who have the grace to recognise that there is a nobility about teaching that far outweighs its laboriousness and the element of repetition, this collection of articles will be a source of inspiration.-H. J. SEDDON.
