PUBLIC 

 HEALTH 



EDITORS' PREFACE 



IN view of the increasing importance of the study of public 

 hygiene and the recognition by doctors, teachers, adminis- 

 trators and members of Public Health and Hygiene Committees 

 alike that the salus populi must rest, in part at least, upon a 

 scientific basis, the Syndics of the Cambridge University Press 

 have decided to publish a series of volumes dealing with the 

 various subjects connected with Public Health^ 



The books included in the Series present in a useful and 

 handy form the knowledge now available in many branches 

 of the subject. They are written by experts, and the authors 

 are occupied, or have been occupied, either in investigations 

 connected with the various themes or in their application and 

 administration. They include the latest scientific and practical 

 information offered in a manner which is not too technical. 

 The bibliographies contain references to the literature of each 

 subject which will ensure their utility to the specialist. 



It has been the desire of the editors to arrange that the 

 books should appeal to various classes of readers : and it is 

 hoped that they will be useful to the medical profession at home 

 and abroad, to bacteriologists and laboratory students, to munici- 

 pal engineers and architects, to medical officers of health and 

 sanitary inspectors and to teachers and administrators. 



Many of the volumes will contain material which will be 

 suggestive and instructive to members of Public Health and 

 Hygiene Committees ; and it is intended that they shall seek 

 to influence the large body of educated and intelligent public 

 opinion interested in the problems of public health.
