An Introduction to Human Experimental Physiology

PUBLIC HEALTH.
Bact. coli, is found in unpolluted waters to an extent sufficient to cause erroneous interpretations. On the whole, they consider the evidence and information are at present inadequate to warrant the general use of this differential test. Useful chapters deal with the bacteriology of sewage and sewage effluents and with shellfish. The latter, however, only deals with oysters, and the examination of mussels and cockles is not considered. None of the three important English methods of examinir, g oysters is mentioned, a regrettable omission, since there is an extensive mass of valuable data in connection with them and upon standards of pollution. Even with these defects from the English point of view, the volume remains a valuable and useful one, and a helpful work of reference.
AN INTRODUCTION TO HUMAN EXPERIMENTAL
PHYSIOLOGY. By F. W. LAMB, M.D., Reader in Physiology, Victoria University, Manchester. London : Longmans, Green and Co., Ltd., 1930. pp. 335, with diagrams. Price 12s. 6d. net. Dr. Lamb has produced a book which stands alone in character among many books bearing similar titles. It is a praiseworthy attempt to place on record experimental methods and easily demonstrable facts of human physiology which have been described in innumerable publications during recent years, and credit is due to the author for the manifest pains he has taken to search out and sift the literature. In a foreword to the book, written by Professor A. V. Hill, emphasis is laid on the importance of the study of experimental physiology with " man " as the subject. The volume is divided into three sections under the general headings: blood, respiration and circulation. In the first section, detailed accounts are given of the methods of investigating t h e physical properties of blood. Under respiration, metabolism and muscular work are treated, and a good account is given of the experimental method of Haldane and Douglas. The pulse, blood pressure, blood flow and electrocardiography are among the subjects treated in the section which deals with the circulation. At the end of each sub-section voluminous references tO the literature are given. The book should prove of g r e a t v a l u e for routine practice work for medical students and for research workers i'n the field of industrial physiology. It is to be hoped that D r : Lamb w!ll corn-

plete his work by producing a second volume covering the nervous system, nutrition and the special senses on similar lines.
THE PURIFICATION AND DISPOSAL OF SEWAGE.
By C. J. NURSE, A.M.I.S.E., late Engineer, K.A.R., Zomba, Nyasaland, Central Africa. L o n d o n : Crosby Lockwood and Son, 1931. pp. 122. Price 4s. 6d. net. The subject of sewage disposal is one that is necessarily ever present; no apology is therefore needed for another publication, providing it has special features. The present volume has the advantage of brevity, and the author has undoubtedly condensed into its pages a very useful outline of sewage disposal as applied to civilised communities; but it must be clearly understood that the book is written, not for the expert, but for those recltti ing a general idea of how this difficult subject is dealt with in different parts of the world. The author has certainly dealt with his subject in a very clear manner, including the principal systems of treatment at present in use throughout this country, and not omitting the most modern practice in sludge disposal and the utilisation of gas obtained therefrom for power purposes. There are chapters on the activated sludge process and methods of analysis, but these are distinctly elementary in character. The illustrations are sumcient to make clear to the layman the general working of the "various processes, and the work can safely be recommended as one suitable for those interested in sewage disposal, including health officers who have to deal with the matter only in a limited sense.
LASCAR HINDUSTANI FOR SHIP-SURGEONS. By S. CHALMERS PARRY, M.A., M.R.C.S.,
L o n d o n : W. J. Clark and Co., t0 and 12, Hanway Street, W.1. pp. 48. Price 2s. 6d. net. This small book, written from actual experience with Lascar patients by a ship-surgeon, who has seen long service with the P. and O. Company, will prove a valuable guide for those who have to deal with sick Lascars on board ship or in their homes, and should also be found of real service to medicaI men in India, and to port medical officers, L.R.C.P.
