PREFACE TO SECOND EDITION It is very gratifying that the second edition of this small book is required less than two years after the publication of the first. We have taken this opportunity of including many of the suggestions made by reviewers of the first edition, and have alsó added two more coloured plates ; the generál arrangement of the book is, however, unaltered. The plate illustrating sickle cell anaemia was drawn from a film given us by Dr. Diggs of the University of Tennessee, to whom we are very grateful. ALFRÉD PINEY. STANLEY WYARD. London, 1932.
