New (5th) Edition

Developmental AnatomyA Textbook and Laboratory Manual of Embryology

JUST READY-The New (5th) Edition of Dr. Arey's book presentswith rare clarity the functional and structural aspects of embryology.This has been a great and outstanding text since publication of thefirst edition, but today in this revised and improved edition, educa-tors will find a teaching instrument unsurpassed in drawing studentresponse.

Dr. Arey's book gives the student not only a complete descriptivetext on embryology, but also a very practical laboratory manual.The arrangement is this: The first section treats the early stagescomparatively and outlines clearly, by means of word and picture,the full course of prenatal and postnatal development. The secondsection traces the origin and differentiation of the human organ sys-tems, grouping them according to germ-layer development. Thethird section comprises a laboratory manual for the study of pig andchick embryos.

New Features AddedDr. Arey has rewritten much of the material not only bringing it up-to-date, butincorporating many important improvements. The features of the New (5th)Edition include:

Many new illustrations and scores of remade pictures bringing thetotal number to almost 1400. New discussions of growth and histogenesis,maturation, cleavage and gastrulation, human embryos and their mem-branes, and placentation. A unification of the material on the fetal mem-branes of vertebrates. Entirely new chapters on reproductive cycles andtheir hormonal control; and on the fundamental concepts and problems ofexperimental embryology.

By LESLIE BRAINERD AREY, PH.D., Sc.D., LL.D., Robert Laughlin Rea Professor of Anatomy, North-western University. 616 pages, 61" x 9'4 , with nearly 1400 illustrations on 590 figures, manyin colors. $7.00

Safe from the sleep-robber . .. feather dustA major cause of irritation, forpersons sensitive to feather dust,is avoided by the use of pillowsfilled with Fiberglas* SuperfineFibers. And similar relief isbeing obtained by persons sensi-tive to products of the disinte-gration or deterioration of otherorganic materials used to fillpillows."Household dust is one of

the two allergens that accountforthe majority of the estimated5,000,000 persons in the UnitedStates who are victims of asthmaand other respiratory disturb-ances, resulting from exposureto allergenic substances

"Principal source of the house-hold dust that causes asthmaticsymptoms is bedding dust thatresults from disintegration ofcotton linters . . . the actualallergen is believed to be a proteinsubstance in the minute air-borneparticles that result from suchdisintegration. Moreover, as

feathers in pillows are cleaned or

renewed, they become brittle; par-ticles break off, get into the air,and are breathed, thus creatingrespiratory distress in those who

are allergic to them." t

The Fiberglas Superfine Fibersused in the pillows are micro-scopically fine fibers of glass,fabricated into resilient batts.The fibers are light, strong, pli-able, moisture-resistant. And,being glass, the fibers are in-organic and, therefore, containno allergenic protein. They are

absolutely safe, from the aller-gist's viewpoint.That repeated use will not

cause the superfine fibers topenetrate the pillow ticking hasbeen established by an inde-pendent testing laboratory.§Furthermore, additional testsshow that, even if particles ofthe fibers should become crushedand penetrate the ticking, thepossibility is very remote thatany contact dermatitis of theface and neck could be caused

by sleeping on Fiberglas-filledpillows.

We will be glad to referyour request for complete infor-mation about Fiberglas-filledpillows to pillow manufacturers.Or data on the subject of Fiber-glas materials and their medicalaspects, will be sent on request.Owens-Corning Fiberglas Cor-poration, Department 2033,Toledo 1, Ohio.
