COMPARATIVEANATOMY

Adopted by 244 Colleges and Universities(Published 1936)

540 Illus. 739 Pages. $4.75

This book is an exceptionally usable and skillfullyprepared text covering the conventional subjectmatter of vertebrate morphology.A chapter is devoted to each anatomical system andthere are brief discussions of the animal kingdom,histology, reproduction, and vertebrate phylogeny.The facts presented throw light on man's place innature and help the student to understand themajor functions of his body.A glossary and excellent illustrations are provided.

CHORDATEANATOMY

Already Adopted by 108 Colleges andUniversities

(Published 1939)378 Illus. 467 Pages. $3.50

Designed to meet the need for a one-semester coursein comparative anatomy, this text introduces thestudent to a sound study of chordate morphology.Embryological, histological and physiological ma-terial enhances the student's understanding of themain subject. Heading each chapter are introduc-tory comments which lay the groundwork for andpoint to the significance of subsequent material.Throughout the text, stages of development andstructures in the lower forms which have analoguesand homologues in man are indicated.

The Electrocardiogramin Congenital Cardiac

DiseaseBY MAURICE A. SCHNITKER, M.D.

ALTHOUGH THERE ARE several other treatiseson the electrocardiogram, Dr. Schnitker's

is the first to contain autopsy proof of its ma-terial. It is, furthermore, the first work of itskind to bring together specific types of lesionsof congenital heart disease in an attempt to cor-relate the electrocardiogram with the type andcharacter of lesions found at autopsy. Theillustrative cases are well distributed, with em-phasis upon those that are most likely to beencountered clinically. Internists, cardiologists,and pediatricians will find this a most impor-tant book of reference.

These superior media are inert, high melting, water-white syntheticresins having many advantages over Canada balsam and gum damar.Clarites have proper refractive indices and adhesion to glass, and willneither become acid nor discolor with age. Clarites are pure, uniform,perfectly transparent, and will not cause stains to fade with age becausethey are absolutely neutral and remain so.

Clarite covering media are used in solution in toluene, 60% Clarite byweight being recommended. Such a solution provides definite advan-tages:-fluidity, less solvent to evaporate, easier application of coverglass, and less chance of trapping bubbles.

Clarite and Clarite "X" Resins are available in lumps or ready-to-use solu-tions. If your local laboratory supply house is not yet carrying these tolu-ene solutions or lump Clarites in stock, write us direct for prompt serviceon orders.

Forty-seven members of RCA among572 industrial engineers and scientists

given awards as "Modern Pioneers on

American Frontiers of Industry."

SINCE its beginning, the Radio Corporation ofAmerica has held that Research in all fields

of radio and sound is one of its major obligationsto the public and to the future of radio.

Research is the keystone of every operation ofRCA. RCA Laboratories are the fountain head ofmany of the spectacular radio and electronic de-

velopments of the past twenty years.Back of these developments... back of the term

Research, in fact...are men. Men make discover-ies. And we at RCA are extremely proud of the

man-power which has elevated RCA Research to

a position of leadership.We wish to add our own congratulations to the

public recognition these men have already re-

ceived. And, in addition, we extend equally warmcongratulations to the many other RCA engineersand scientists whose brilliant work is contributingso much to the progress of their industry.

Ofthe 572 industrial engineers and scientists chosenby the National Association of Manufacturers toreceive awards as "Modern Pioneers on AmericanFrontiers of Industry," forty-seven were members ofthe RCA organization. The awards were given fororiginal research and inventions which have "con-tributed most to .the creation of new jobs, new

industries, new goods and services, and a higherstandard of living."

Special national awards were given by the NationalAssociation of Manufacturers to nineteen of thosereceiving honors. Dr. Vladimir K. Zworykin of theRCA Manufacturing Company was chosen to receiveone of these national awards.

Three Spencer Instruments in One

THE SPECTROMETER ... THE SPECTROGRAPH... THE SPECTROSCOPE

THE usefulness of the Spencer Spectrometer is greatly in-creased by the attachments now available.The specially designed Spencer precision camera when used inplace of the telescope (as shown in the illustration) convertsthe Spectrometer into a Spectrograph. With it, a series ofspectra may be photographed on the same plate.Another attachment converts the Spencer Spectrometer intoa Bunsen Spectroscope for visual demonstrations and com-parisons of spectra of the chemical elements.Spencer Spectrometers are used in the physics laboratories ofnumerous colleges. Such acceptance pays high tribute tothe precision, adaptability, and optical quality of Spencerinstruments.

Write Dept. C3 for the new Spencer booklet which describes a num-ber of interesting experiments and demonstrations which may be made

with this equipment.

In a paper emanating from the Merck Research Laboratoriesand published in the April 14, 1939 issue of Science, Harrisand Folkers announced their success in accomplishing thetotal synthesis of vitamin B6.

This achievement followed in rapid succession the success-ful isolation of vitamin B6 by Keresztesy and Stevens of theMerck Research Laboratories and the subsequent determi-nation of its structure by Stiller, Keresztesy and Stevens ofthe same laboratories.

Thus through the orderly progression of research, vitaminB6-identical in every respect with the naturally occurringvitamin-has been made abundantly available for clinical usein pure crystalline form.

EPISODES AND PERSONALITIES IN THE DEVELOPMENTOF BIOLOGY AT BROWN1

By Dr. A. D. MEADBROWN UNIVERSITY

IN the diamond jubilee number of the AtlanticMonthly, issued in November, 1932, seventeen articlesselected from the 900 monthly issues of the Atlanticwere reprinted. One of them was Dallas Lore Sharp'sfamous paper on "Turtle Eggs for Agassiz" (1910),which already had been reprinted many times andwhich, incidentally, has been read by Dr. Walter tohis class in comparative anatomy in Brown every yearfor a quarter of a century. Now this touches mysubject at several points: The hero of the episode wasJ. W. P. Jenks, the first teacher of zoology at Brown.Jenks was a lifelong disciple of Agassiz and widelydisseminated his doctrines at Brown and elsewhere.Sharp was a student at Brown (1895) and a special1Address at the dinner of the National Academy of

Sciences, Brown University, October 24, 1939.

protege of Professor Jenks, from whom, while atBrown, he got the tale about the turtle eggs. Again,Sharp's own colorful career at Brown, if as ade-quately written up, would win a place in literature.And finally, his introduction to the turtle egg paperprovides the theme, which is at least implied, of thispost-prandial talk, namely, that the progress of ascience in a period of years, like a game of golf in an

afternoon, is not completely recorded in the mereenumeration of the end results and the scores, butthat personalities and minor dramatic incidents are avital and substantial part of the story.Sharp found the clue to his story in Agassiz's four

volumes of "Contributions to the Natural History ofthe United States." "The volumes," he said, were

"massive, heavy, weathered as if dug from the rocks,"
