BOOK REVIEWS

student nurses ", and has studied their needs withincreasing sympathy and discernment. In the prefaceto the first edition she explained that for several yearsshe had taught psychology to " student nurses from fivelocal hospitals,-who have come to the university for thefirst sixteen weeks of their academic training ". Onecannot help reflecting on the good fortune of theseyoung ladies of Toledo: first in being saved from thefate of learning about psychology from the averagesister-tutor, herself inadequately trained; secondly inreceiving their first impressions of the subject before therest of the nursing curriculum has made its mark; andthirdly in meeting with a university teacher who makes asincere attempt to use the findings of education andpsychology in her own methods.To British readers the book may at times seem

American in style and content, but it is much less sothan might have been expected, and the clarity ofexposition generally compensates for this. Though herreferences are mainly to books and papers published inthe U.S.A., her choice is eclectic and up-to-date. Everychapter is provided with a summary, suggested activitieslikely to provide applications of the theoretical content,and a short bibliography for suggested reading, brieflyannotated. She also provides a formal list of ' Refer-ences Cited in this Chapter ", which might well havebeen dispensed with or brought together at the end ofthe book, as the practice leads to frequent multipleentries of the same books and papers. The book isprovided with a useful, non-technical glossary of un-familiar terms, and adequate author and subject indexes.Although the orientation throughout is toward thenurse, this text can be recommended to medical studentsand to more senior people such as industrial medicalofficers, requiring a simple but scientifically-basedprimer in modern psychology. ALASTAIR HERON

Eyes in Industry. By D. A. Campbell, W. J. B.Riddell, and A. S. McNalty. (Pp. 227 plus index;illustrated. 30s. net.) London: Longmans, Green.1951.Dorothy Campbell and her associates have written-

a most useful and basic treatise on the anatomy andphysiology of the eye and its relationship to industry.It will be useful to personnel directors, safety engineersand management, and ophthalmologists not familiarwith industrial problems. With that special genius thatthe British have, the authors have made the text lucidand complete, binding the complicated angles into asingle integrated whole.

It is strange that she in Britain and I in the UnitedStates should produce books, the titles of which are soalike. There, however, the similarity ends. DorothyCampbell has done everything that I wanted to do butcould not, namely, make the basic functioning of the eyeunderstandable to anyone reading it. Her diagrams,photographs, and her definitions of even the mosttechnical material, are well done. There are things shestresses that we in this country should stress and havenot, for instance, the care of adolescent eyesight and itsrelationship to industry.

F

Professor W. J. Riddell has written the second part ofthe book on visual hazards, injuries in industry, andtheir prevention. The important chemical research ofthe British war period is reflected. Miner's nystagmus,non-existent in the United States, has been the subjectof British research for a long time. Most of the evi-dence seems to suggest that the absence of this diseasein the U.S.A. is due to better lighting and a greaterfeeling for safety, and that miner's nystagmus is basicallya psychomatic problem, but the final word has not yetbeen said. Britain, fortunately, was not a victim ofepidemic kerato-conjunctivitis as we were and are still insome areas of this country, so they have nothing tocontribute to this ever threatening problem. Sir ArthurMcNalty has written part three on special aspects,injuries, and psychology of sight.

Research in visual testing in industry, the perfectionof the equipment for this and the study and interpre-tation of the results, has hardly even started in Britainwhile it has made tremendous advances in the States.Elaborate eye protective equipment such as has beenpromoted in this country is not available in England.That the authors do not discuss the relationship of

the professional eye man with plant management andpersonnel reflects the loose character of their arrange-ments. Also, no mention is made of what we considerto be vitally important, namely the need for carefullyoutlined first aid technique and standing orders fornurses. While visiting British plants and talking totheir industrial nurses I felt there had been too muchleeway given to nurses. I am sure that their legal statusdoes not include the practice of medicine, i.e. workingand prescribing other than directly under defined doc-tor's orders. In the States we are very strict and ournurses are glad of the protection.To anyone who wants to and needs to understand

physiological and psychological visual functions andtheir relationship to industry this excellent book will bevaluable. HEDWIG S. KUHN

Occupational Health PrizeThe Council of the British Medical Association is

prepared to consider the award of an occupational healthprize in the year 1953. The prize consists of a certificateand a money award to the value of £50.The prize is established by the Council of the Asso-

ciation to encourage interest and research in the fieldof occupational health.The prize will be awarded biennially.Any member of the Association who is engaged in

the practice of occupational health, either whole-time orpart-time, is eligible to compete for the prize. Candidatesmay select their own subject.The essay submitted must include personal observations

and experiences collected by the candidate in the courseof his work. If no essay entered is of sufficient meritno award will be made. Candidates in their entriesshould confine their attention to their own observationsrather than to comments on previously published workon the subject, though reference to current literatureshould not be omitted when it bears directly on theirresults, their interpretations, and their conclusions.

Essays, or whatever form the candidate desires hiswork to take, must be sent to the Secretary, BritishMedical Association, B.M.A. House, Tavistock Square,London, W.C.1, not later than December 31, 1952.No study or essay that has been published in the

medical press or elsewhere will be considered eligiblefor the prize, and a contribution offered in one yearcannot be accepted in any subsequent year unless itincludes evidence of further work. A prizewinner in anyyear is not eligible for a second award of the prize.

If any question arises in reference to the eligibility ofthe candidate or the admissibility of his or her essay, thedecision of the Council on any such point shall be final.

Preliminary notice of entry for this competition isrequired on a form of application to be obtained fromthe Secretary.

Each essay must be typewritten or printed on one sideof the paper only, must be distinguished by a motto,and must be accompanied by a sealed envelope markedwith the same motto and cnclosing the candidate'sname and address.

Inquiries should be addressed to the Secretary.

Scholarships in Aid of Scientific ResearchThe Council of the British Medical Association is

prepared to receive applications for research scholar-ships, as follows:

An Ernest Hart Memorial Scholarship of the valueof £250

A Walter Dixon Scholarship of the value of £250One or More Research Scholarships each of the

value of £200These scholarships are given to candidates whom the

Science Committee- of the Association recommends asqualified to undertake research in any subject (includingState medicine) relating to the causation, prevention, ortreatment of disease.Each scholarship is tenable for one year, beginning

on October 1, 1953. A scholar may be re-appointed fornot more than two additional terms. A scholar is notnecessarily required to devote the whole of his or hertime to the work of research, but may be a member ofH.M. Forces or may hold a junior appointment at auniversity, medical school or hospital, provided theduties of such appointment will not, in the opinion ofthe Science Committee, interfere with his or her workas a scholar.

Applications for scholarships must be made not laterthan March 31, 1953, on the prescribed form, a copy ofwhich will be supplied by the Secretary on application.

Applicants are required to furnish the names of threereferees who are competent to speak as to their capacityfor the research contemplated.
