AN INTRODUCTION TO

HUMAN PARASITOLOGYBy ASA C. CHANDLER

Professor of Biology, The Rice Institute

So marked has been the advance in knowledge in the field of parasitology since the. fourth editionof this widely used textbook was published six years ago, that a thorough rewriting of the texthas become necessary. Particularly extensive changes have been made in the chapters or sectionsdealing with the spirochaetes, amebae, malaria, rickettsias, flukes, Strongyloides, filariae andmyiasis, but the prolific work of parasitologists during the past six years has necessitated or madedesirable some changes on almost every page.

Up-to-date material added to the book-(1) The discovery of a new strain of relapsing fever spirochaetes in Texas(2) The unprecedented outbreak of amebiasis in Chicago(3) The important contributions to epidemiology and immunology of malaria growing out of

its use in treating neural syphilis(4) Duke's interesting work on the interrelations of African trypanosomes(5) The final settlement of the controversy over the life cycle of Trypanosoma cruzi(6) The prolific work on the classification and relationships of typhus-like diseases(7) New developments in knowledge of yellow fever(8) Faust's work on Schistosoma mansoni in Puerto Rico(9) The discovery by Africa et al., of the production of heart lesions by heterophyids

(10) The discovery of important steps in the life cycles of Euparyphium ilocanum, Strongy-loides, Mansonella ozzardi, Gnathostoma spinigerum, and Microfilaria malayi

(11) New work on the anemia and pathology of hookworm disease(12) O'Connor's corroboration of Lane's hypothesis concerning filarial periodicity(13) The extensive work of Strong and his colleagues on onchocerciasis in Africa and Guatemala(14) The numerous investigations on races of Anopheles in relation to malaria transmission(15) The discovery of separate parasitic and saprophagous species of myiasis-producing flies(16) The relation of fleas to the transmission of endemic typhus(17) New developments in the treatment of amebiasis, malaria, trypanosomiasis, hookworm

ways its grants are enriching the staff and work of theuniversity. Its stimulation is being felt all the wayfrom promising young scholars to our most distin-guished scientists of maturity."Of the total grant, $84,000 is allotted to special

grants-in-aid to stimulate university research. Theseare used to purchase equipment and supplies and tohelp to support more than a hundred young men andwomen graduate research workers. Included in thegrant is a new fund of $25,000 to permit faculty mem-bers to carry on during the summer months certainlines of research which are already underway.

There is also included a $15,000 fund for the con-tinuation of the special fellowships and scholarshipsinaugurated a year ago, and known as the WisconsinAlumni Foundation Fellowships for gifted youngscholars and students of science. Funds for theirsupport this year have been increased $5,000 over the$10,000 given for them last year. At the present timetwenty-three young men are carrying on research workunder these fellowships. They are selected for theirattainments from all parts of the country.An additional fund of $5,000 is included in this

year's grant for the establishment of two or morepost-doctorate fellowships with which it will be pos-sible to bring to the state university gifted men whohave already proved their ability to carry on indepen-dent research work in the natural sciences.The grant also includes $8,000 which will provide

for the continuation of the work now being done byProfessor Aldo Leopold on game management and thewaste land problems and $1,000 for the continuationof the lectureship fund, which each year brings to theuniversity a leading investigator to lecture on somephase of the natural sciences.

THE TENTH ANNUAL PRIESTLEYLECTURES

DR. WARREN K. LEwis, professor of chemical engi-neering at the Massachusetts Institute of Technology,will be the tenth annual Priestley lecturer at the Penn-sylvania State College. The lectures will deal with theinterrelationships between physical chemistry andchemical engineering, and will be given in the chem-istry amphitheater of the college, at 7: 00 P.m., onMarch 23, 24, 25, 26 and 27.

Professor Lewis, Perkin medallist for 1936 andone of the founders of chemical engineering, haschosen for his topic, "The Borderline Between thePhysical Chemistry of Fluids and the Behavior ofSuspensions." The five lectures will deal with thestructure of liquids, the viscosity of fluids, suspensionsand emulsions, and gelation.The Priestley lecture seriess was inaugurated by the

faculty of the department of chemistry in 1926 as amemorial to Joseph Priestley, the discoverer of oxy-gen, whose American laboratory was situated only afew miles from State College. In 1931 the Penn StateChapter of Phi Lambda Upsilon (Honorary Chemical.Society) undertook the financial support of the lectureseries. These lectures, therefore, now constitute ajoint memorial to Joseph Priestley on the part of boththe faculty of the department of chemistry and of thePenn State Chapter of Phi Lambda Upsilon.The Priestley lectures deal each year with the bor-

derline between physical chemistry and some otherbranch of science. Previous Priestley lecturers andtheir borderline topics are:

1927-Dr. V. Cofman, E. I. du Pont de Nemours andCompany-Biocolloids.

1928-Dr. S. L. Hoyt, General Electric Company-Metallurgy.

1929-Dr. H. B. Williams, Columbia University-Medicine.

1930-Dr. L. Navias, General Electric Company-Ceramics.

1931-Dr. J. W. Williams, University of Wisconsin-Electrical Engineering.

1932-Dr. V. K. LaMer, Columbia University-Bio-chemistry.

1933-Dr. E. R. Jette, Columbia University-Metal-lurgy.

1934-Dr. R. A. Gortner, University of Minnesota-Life Processes.

1935-Dr. M. A. Hunter, Rensselaer Polytechnic Insti-tute-Electro-metallurgy.

RECENT DEATHSTHE death is announced of Dr. William G. Krauss,

AN INEXPENSIVE MAGNIFIER FOR READ-ING FILM COPIES OF SCIENTIFIC

ARTICLESSINCE the library of the U. S. Department of Agri-

culture has been distributing copies of papers in theform of film copies, there has been considerable inge-nuity shown in various institutions to find some methodof reading them. A recent paper,' for instance, re-

ports the use of a binocular dissecting microscope forthis purpose.

It is now pretty well known that there is a magnifierfor this purpose on the market and that a special pro-

jector is being developed for rendering the films easierto read than with the use of the magnifier. To thewriter it seems as if the-ideal method for any institu-tion to arrange for reading these films received by itsmembers would be to have a projector in some centralplace, designed for use in careful study, and a mag-

nifier intended for more superficial perusal availableto each member of the staff who would be likely toreceive articles sent out in this form. The presentcost of the magnifiers, however, might make this outof the question in some institutions.For this reason it was with much interest that a

still cheaper magnifier already on the market (price$1) was recently observed. This magnifier is ordinar-ily sold as a sort of toy and designed for looking withboth eyes at stereoscopic views of pictures put out bythe company manufacturing the magnifier. The mag-

nifier is sold under the trade name "Tru-vue" and is a

product of the Rock Island Bridge and Iron Works,1 G. R. Coatney, SCIENCE, 82: 105, 1935.

Rock Island, Illinois. The films that the company sup-plies for use with this magnifier are standard 35 mmcinema films, the same as used for the film-stat repro-ductions. Accordingly, the latter can be used in this"Tru-vue" magnifier by simply blocking up one eye-hole in it so that one is not looking at one page withone eye and at another page with the other.The magnification thus secured is less than with the

magnifier designed especially for reading these films,and no focusing is possible. The "Tru-vue" magnifieris set in focus for use with normal eyes, and as a resulta far-sighted or near-sighted person can not use itexcept with his glasses in addition. The writer hashad a number of different individuals try it, however,and although some have experienced more difficultythan others in reading the text, no one has provedunable to do so if he also used properly fitted glassesand had sufficient illumination.Although this magnifier is not as perfect, therefore,

as the one put on the market for this particular pur-pose, it has two advantages over the latter: first, itslow price; and second, the fact that it is so small thatit can be carried in a pocket or handbag. This latterfeature should make it of use to travelers who wish tocarry a film collection of articles with them.
