Important to Those Who Are

Studying the Nervous System

.

Gardner's Introduction to NeurologySeldom will the student find a textbook thatsimplifies the complex as does this new neurol-ogy book. Beautifully illustrated, it is wellwithin the grasp of college students with aminimum background in biology.It progresses systematically from the develop-ment of elementary fundamentals to the moreadvanced concepts-including the relationshipsof psychology to the higher nervous centers.Work on animals has been included in numer-ous instances for comparative purposes, as thistype of material throws further light on the

nervous system in man. Clinical applicationsare incorporated whenever they may clarify thestudent's understanding of the basic functionsof the system.

Instructors will find that this book will serveadmirably as a college text for students in zool-ogy and physiological psychology. It will provevaluable in schools of physical and occupationaltherapy and for short courses in medicine, den-tistry and allied fields. Physical educators willfind it a valuable reference work in kinesiologyand corrective physical education.

Wiley books for study, research and referenceFOUNDATIONS OF PSYCHOLOGY

Edited by EDWIN G. BORING, Profes.sor of Psyichology. Harvard University; HERBERT S.LANGFELD, Stuart Professor of Psychology, Emeritus, Princeton University; and HARRY P.WELD, Professor of Psychology, Emeritus, Cornell University, Visiting Professor of Psychology,Rice Institute.

Each chapter of this new book is written by a recognized authority in the subject covered. Thewhole manuscript has been carefully checked and edited by the above three men, experienced authorsin their own right. The resulting book is authoritative and consistent in statement, terminology andstyle. Suggestions received from a canvass of many colleges brought about this change: usual textorder has been revised. It now begins with response, and concludes with chapters on personality,personal adjustment, vocational selection, attitudes and opinion, and social relations.Ready in April Approximately 574 pages Probable price, $4.00

Preparation and Characteristics of

SOLID LUMINESCENT MATERIALSPublished by arrangement with the American Physical Society, under the auspices of the NationalResearch Council. Edited by GORTON R. FONDA, General Electric Company, and FREDERICKSEITZ, Carnegie Institute of Technology.

This is one of the most important books in the field ever to be published. It includes 29 paperswhich were first read in late 1946 at a symposium of the Division of Electron Physics. General dis-cussions of the subject were recorded and are included. The papers and discussions offer: a generalsurvey; theory of luminescence phenomena; purification, crystallization and constitution of lumines-cent materials; new information collected during the war years; a summary of the present status ofthe field; and suggestions and opinions which point the way to needed research.Ready in April Approximately 459 pages Probable price, $6.00

DAIRY BACTERIOLOGY

by B. W. HAMMER, Formerly Professor of Dairy Bacteriology, Iowa State College.

The Third Edition of this widely-used book has been considerably changed and expanded. Achapter on dairy plant water supplies is included for the first time. Discussions of powdered milk,butter, cheeses and water supplies have been enlarged in the light of today's concepts. As in theprevious editions, a direct method of instruction is used and clear-cut sources of information are pre-sented for both pathogenic and normal bacterial developments in each product. Professor Hammerhas stressed fermentations in milk and its derivatives, because his experience has shown that an under-standing of this subject is essential to a working knowledge of dairy bacteriology.Ready in April Approximately 595 pages Probable price, $6.00

CHEMICAL CONSTITUTION OF NATURAL FATSby T. P. HILDITCH, Campbell Brown Professor of Industrial Chemistry, University of Liverpool,England.

Rapid advances made during the last seven years make this Second Edition even more inclusivethan the first, of which Chemical Engineering said: "A veritable encyclopedia of information." Inthis book fats are classified along biological lines because their component acids are so closely con-nected with the biological source. This work includes: introductory survey; component acids of fatsof aquatic flora and fauna, land animals, and vegetables; component glycerides- of natural, vegetableand animal fats; aspects of the biochemistry of fats; constitution of individual natural fatty acids;synthetic glycerides; notes on experimental technique.In press Approximately 554 pages Probable price, $9.00

THE 8 MICROTOME KNIFE SHARPENERfulfills the need of every laboratory for an efficient precisionmethod of resharpening all standard microtome knives

In leading laboratories throughout the country theBERKELEY MICROTOME KNIFE SHARPENER hasproved itself to be the indispensable companion instru-ment to the Microtome.Cutting Edges sharpened with the BERKELEY SHARP-ENER are hollow ground, far superior to those producedby any other means-yet the job is done three timesfaster than by the usual laboratory methods. The tech-nique is simple and readily learned-and eliminates allstropping and honing.If Microtomes are used in your laboratory you will findour new illustrated bulletin of great interest. It givescomplete information and shows comparison photomicro-graphs of cutting edges sharpened by hand and (in one-third of the time) on the BERKELEY MICROTOMEKNIFE SHARPENER.
