THE CAMBRIDGE 
PUBLIC HEALTH SERIES 
Under the Editorship of 
G. S. GRAHAM-SMITH, M.D., and J. E. PURVIS, M.A. 
The books included in this 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. It is hoped that the volumes will be useful to the medical 
profession at home and abroad, to bacteriologists and laboratory students, to 
municipal engineers and architects, to medical officers of health and sanitary 
inspectors and to teachers and administrators. Details of the three volumes 
already published will be found below, and a list of volumes in preparation 
will be sent on application.

“The fact that the book is published at the Cambridge University Press is sufficient 
guarantee of the excellence of the printing and binding....We can only say that if the other 
volumes of this series...are as good as this one, a very high standard of excellence 'will have to 
be maintained. We consider that no one in the Public Health Service should be without this 
book .”—Medical Times 
Isolation Hospitals. By H. Fkanklin Parsons, M.D., D.P.H., formerly 
First Assistant Medical Officer of the Local Government Board. Demy 
8vo. With 55 text-figures. 12s. 6d. net. 
The special aim of the author has been to produce a work which shall be of practical use to 
members of local authorities, medical officers of health, hospital superintendents and others 
interested in the establishment or management of hospitals for infectious diseases ; and he hopes 
that the experience gained during a long official career may have enabled him to include some 
useful information and suggestions not otherwise readily obtainable. 
The Bacteriological Examination of Food and Water. By 
William G. Savage, B.Sc., M.D., D.P.H., County Medical Officer of 
Health, Somerset. Demy 8vo. With 16 illustrations. 7s. 6d. net. 
In the majority of textbooks and manuals upon Bacteriology the bacteriological examination 
of water, air, foods and the like is most inadequately treated. This branch of bacteriology is of 
immense practical importance and justifies a more extended treatment. The aim of this volume 
is to remedy this defect and to make available a practical manual dealing not only with the 
examination of these substances but also with the deductions to be drawn from the bacteriological 
data obtained from their examination. Much of the available information is only at present to 
be found in original papers not readily accessible.
