Ward's, America's oldest natural sciencesupply house, presents the first commerciallysuccessful transparent plastic mounting forsoft-bodied biological specimens.

Bio-Plastic preparations consist of smallblocks of crystal clear plastic in which areembedded pig and chick embryos, cartilagestructure, jelly fish and other soft biologicalforms.The teaching advantages of Bio-Plastic are

many. Permanent, easy to handle, Bio-Plasticmay be studied under the microscope, viewedwith the hand lens, or examined from all angleswith the naked eye.No longer need the teacher worry about loss

of valuable study objects. Bio-Plastic is in-destructible. Classroom wear and tear is elimin.ated.Ten Bio-Plastic specimens all suitable for

high school classes are listed below. Ward'sintroductory price for all ten is $27.50-save$3.00. Clip coupon and mail.

HYPNOTISM TODAY

By Leslie M. LeCron, B.A. and Jean Bordeaux, Ph.D.

This is the first presentation of the much debated subject which isbased on the results of the important practical and experimental workcarried out in recent years. The authors, both consulting psychologistsengaged in psychotherapeutic work, present the material in two parts:I. HYPNOTISM and SUGGESTION which includes such subjects as inducinghypnosis, hypnotic phenomena, autohypnosis. II. HYPNOTHERAPY,dealing with functional as well as psychosomatic therapy and with hypno-analysis.

LOR ATLAS

OF HEMATOLOGY

with Brief Clinical Descriptions of Various Diseases

by Roy R. Kracke, M.D.

Dean and Professor of Clinical Medicine MedicalCollege of Alabama

Thirty-two plates in full color are the outstanding feature ofKracke's Color Atlas of Hematology. Only in full color il-lustrations of the blood cells could minor variations in diseasesbe so clearly illuminated, and with such conclusive, time-saving

ns clarity. It covers virtually every known blood disease, in-

corporating brief clinical descriptions of each in the text. Anexcellent chapter on blood parasites, including malarial pa-

rasites, and the newest material on the Rh factor are otheroutstanding features. Important, helpful chapters discussthe leukopenic syndromes, splenomegalic diseases and sple-nectomy. Technicians will find particularly useful a sectiondetailing modern hematologic technics and definitions of terms.Factual descriptions of the origin of blood cells and the bloodpictures of laboratory animals are also given. This workingmanual provides a wealth of painstakingly culled, profuselyillustrated, specialized information never before found in an

American book on this subject.

Television

is twenty

years old

At the 1927 demonstration, Dr. Herbert E. Ives explainedthe television system developed in Bell Telephone Laboratories.

APRIL 7 is a notable day in communicationhistory, for on that day in 1927 was the firstdemonstration of television over long distances.Uarge-scale images were flashed from Washing-ton, D. C. by wire and from Whippany, N. J.,ky radio to a demonstration in New York City.'It was," said a newspaper, "as if a photographhad suddenly come to life and begun to smile,talk, nod its head and look this way and that."That was the first of many public demonstra-

tions, each to mark an advance in the televisionart. In I929 came color television, and in 1930 atwo-way system between the headquarters build-ings of A. T. & T. and Bell Laboratories. When

the first coaxial cable was installed in 1937, tele-vision signals for 240-line pictures were trans-mitted between Philadelphia and New Yorkand three years later 44x-line signals weretransmitted. By May, 1941, successful experi-ments had been made on an 8oo-mile circuit.End of the war brought a heightened tempo

of development. Early in 1946 began the regularexperimental use of coaxial cable for televisionbetween New York and Washington, and a fewmonths later a microwave system for televisiontransmission was demonstrated in California.

Transmission facilities will keep pace as a greatart advances to wide public usefulness.

Kodak develops special emulsions torecord individual corpuscular tracksFor ready identification of nuclear re-

actions, Kodak research provides fine grainAlpha Particle Plates and Film to recordalpha particles, deuterons, and protons asindividual tracks rather than over-all ex-posure density.These emulsions, 25 microns thick, reveal

particle paths as close-spaced grains. . . withfew gaps ... low background fog. They arerelatively insensitive to light and gammaradiation. To accentuate deuteron and pro-ton sensitivity, boron can be introducedinto the emulsion either in manufacture orby pre-exposure bathing. Kodak can supplythese plates and films in any size to meetindividual convenience.Kodak invites you to write for more in-

Nuclear particle recordinianother important function of photograpi

COLORIMETER

No standards need be prepared. No calcu-lations. No calibrations are necessary. TheLeitz Pre-calibrated Photo-Electric Colorim-eter is supplied complete with a hand-book ofmethods and calibration tables for 38 differentbio-chemical procedures. These include allstandard clinical determinations (see list).After presetting the instrument, the unknownis inserted and the reading on the meter noted.... A calibration table indicates the concen-tration of the unknown. Variations encoun-tered in visual color matching are completelyeliminated. Identical readings on a specimencan be obtained by different laboratoryworkers.This simplicity and convenience of operation

is combined with the precision and sturdinessassociated with Leitz instruments. Each LeitzPhoto-Electric Colorimeter is individually cali-brated. A high degree of accuracy is main-tained in calibrating and preparing the finaltables.

SOLUTION SUPPLY SERVICEAccurately prepared standard reagents for

clinical chemistry determinations can be ob-tained promptly from our "Solution SupplyService." Solutions are freshly prepared andimmediately shipped.

UNDTERI-STANDINGSCIENCE

An Historical ApproachJAMES B. CONANT

James B. Conant, President of Har-vard University and one of the coun-try's most eminent scientists, tellshere howhe believes the layman canfind out what science is and how tounderstand it. To accomplish thishe presents an historical view of anumber of the great scientists, ofwhat their generation knew of theirsubjects, of the problem they setout to examine, and of how theysolved it. Thus the reader is en-abled to follow in a new way thescientific method at work, with allits limitations and wonders.

ITS HISTORY, NATURE, AND CLINICAL USE

By A. R. McIntyre, M.D.Tracing the history of curare since its

original use as arrow poison, Dr. McIntyredescribes its chemical properties and themethods used to refine it, evaluating thepreparation of curare for clinical use. Onthe basis of his own experiments and thoseof other authorities on this remarkable drug,he explains the value of curare as a thera-peutic agent.

The QUARTERLY JOURNAL ofMICROSCOPICAL SCIENCE

'~ (Edited by C. F. A .PANTIN and JOHN R. BAKER)

START OF A THIRD SERIESA New Series of this Journal, the third since its foundation by

Edwin Lankester and George Busk in 1853, will begin in March,1947.

In the Third Series the Editors propose to give particular en-couragement to two fields of investigation, FUNCTIONA LMORPHOLOGY and CELLULAR BIOLOGY. They will up-hold the tradition of the Journal for the publication of accurateresearches in MICROANATOMY and their policy will be toincrease considerably the publication of papers relating structureto function in all its aspects.

No journal published in Great Britain has devoted itself espe-cially to histochemical problems, though ever since its foundationthe "Q.J.M.S." has from time to time published importantpapers in this field. The Editors now propose to devote a con-siderable part of their space to HISTO- AND CYTOCHEMIS-TRY and to the study of the fine structure and properties ofbiological systems. Papers and short notices on MICROSCOPI-CAL METHODS AND APPARATUS will also be published.

Certain changes in printing and in the reproduction of figuresare being made to improve the presentation to the reader.

Intending CONTRIBUTORS are asked to read the notice onthe back cover of the current number of the journal.

The SUBSCRIPTION is £313/-for the four parts that consti-tute a Volume. For this sum (prepaid) the journal is sentpost-free to any part of the world. Subscriptions should be sentto the Clarendon Press, Oxford, or to the Oxford UniversityPress, London, E.C.4.
