FUNDAMENTALPRINCIPLES OF

PHYSICAL CHEMISTRYBy Prutton & Maron

Case School of Applied Science

This text provides a thorough moderntraining in the essential principles ofphysical chemistry, their effective use,and their correct application. Its aimis to give the student the sound trainingin the fundamentals of physical chem-istry which will enable him to under-stand the science both in a general andqualitative way and also in its more ex-perimental and quantitative aspects. Itis intended primarily for a full year'scourse in physical chemistry for studentsof chemistry and chemical engineering,but is readily adaptable to any one-semester course for students in otherbranches of science.

JOURNAL OFPOLYMER SC IENCE

Editorial BoardP. M. DOTY R. HOUWINK H. MARK C. C. PRICE

* DEVOTED to the advancement of the chemistry and physics of polymers.

* OFFERS to scientific workers in this field an opportunity to report experi-mental and theoretical results through a centralized medium.

* INTERNATIONAL in scope and represents all the important centers ofpolymer research in the United States and abroad. The edi-torial policy is to encourage freedom of discussion.

To avoid the coexistence of two journals devoted topolymer research, Elsevier Publishing Company,Inc. and Interscience Publishers, Inc. have consoli-dated their separate plans for two periodicals into thepublication of only one. The Journal of PolymerScience is therefore the result of the merger of the""Journal of Polymer Research" and the journal "HighPolymers" planned in Holland.

Bimonthly. First year 1946. Yearly subscription $8.50Volume I approx. 640 pages.

Postage free in the U.S.A. Foreign postage, including Canada $1.00

Manuscripts for publication and books for review should be submitted tothe Editorial Office, Polytechnic Institute of Brooklyn, Brooklyn 2, N. Y.Authors will receive 50 reprints of their articles without charge.

PHYSICAL CHEMISTRY FOR PREMEDICAL STUDENTSBY JOHN PAGE AMSDEN, Dartmouth College. International Chemical Series. 298 pages, $3.50

This text is written especially for a one-semester course for premedical students. It includes onlythose portions of elementary physical chemistry which will be of value to the medical student in hislater professional work. Worked-out problems illustrate each topic discussed. Throughout the textthe Bronsted concept of acids and bases has been used. Many lecture demonstrations are described.The mathematical requirements have been kept to a minimum.

TEXTBOOK OF BIOCHEMISTRYBy PHILIP H. MITCHELL, Brown University. 651 pages, $5.00

Designed for a first course in biochemistry, following the study of organic and introductory physicalchemistry. The author presents a modernized treatment of the essentials of biochemistry, centeredupon metabolism and human nutrition. At the same time, the book deals with older established bio-chemical knowledge. Discusses the important materials of life; photosynthesis; digestion, absorp-tion, and metabolism; acid-base balance; energy balance; vitamins; enzymes; hormones; etc.

MATHEMATICAL THEORY OF ELASTICITYBy I. S. SOKOLNKOFF, University of Wisconsin. 373 pages, $4.50

Exceptionally thorough and compact, this lucid treatment covers the basic theory of mechanics ofdeformable media. After a presentation of the mathematical theory of elasticity, the author dealswith the application of the theory to problems on extension, torsion, and fiexure of isotropic cylin-drical bodies and with variational methods in the theory of elasticity.

AN INTRODUCTION TO BOTANY. New second editionBy ARTHUR W. HAUPT, University of California at Los Angeles. McGraw-Hill Publicationsin the Botanical Sciences. Ready in May

As before, this well known text is designed for a one-semester course in botany covering the funda-mental facts and principles relating to the structure, function, and life relation of plants. The bookhas been entirely revised in accordance with present-day knowledge, a number of chapters have beenwholly rewritten, and much new material has been added.

PRINCIPLES OF ANIMAL BIOLOGY. New sixth editionBy A. FRANKLN SHULL, University of Michigan. With the collaboration of GEoRGE R. LARUEand ALEXANDER G. RUTHVEN, University of Michigan. McGraw-Hill Publications in theZoological Sciences. Ready in May

In the present revision of this standard text the authors have made numerous changes which tendto emphasize fundamental concepts. The treatment of function has been stressed. Every chapterhas undergone revisions which are designed to- clarify the exposition and bring it abreast of currentideas. In many instances descriptions have been made more explicit, and illustrated by simplediagrams. 0

A PERSONAL SERVICEFor Scientists

Scientists no less than other Americans are facedwith personal reconversion problems. In keepingwith its policy of giving maximum service to allscientists, SCIENCE has expanded its personal clas-sified advertising section. An announcement inSCIENCE of availability for a more responsible posi-tion, is a dignified and effective method of securingprofessional advancement. The advertiser's identitymay be protected adequately through the use of abox reply address.

Readers of SCIENCE are invited to use the new sec-tion, PERSONNEL PLACEMENT, as a means of detail-ing their qualifications. Those scientists now beingdemobilized from the armed forces or seeking newpositions because of termination of war employmentwill find it an economical way to solve their employ-ment problems. Employing officers of colleges, uni-versities, and industrial research laboratories will like-wise find this service valuable for attracting qualifiedpersonnel. For complete details see page 18 of thisissue.

~MAGARC,Completely Automatic - Magnetic Feeding

CARBON ARC LAMPA new principle in carbon arc microscope lamps . . .Magnetically controlled feeding of carbons assures con-tinued, positive performance throughout the life of thecarbons.

The MAGARC Has These Outstanding Advantages:The feeding of the carbons is completely automatic in theexact ratio of their consumption....The gap of the arm-the distance from the tip of the posi-tive to that of the negative carbon-is continuously andautomatically adjusted, throughout the entire period oftime required for the consumption of one pair of carbons(about 1 2 hours).Corrective manual adjustments are not necessary.

"Jumping" of the arc does not occur. Current consump-tion for which the lamp has been designed (10 amperes)is high enough to extend the area of highest intensitythrough practically the entire area of the cross sectionof the carbon.Current consumption and light intensity are maintainedat a relatively constant level.Distance from the light source to the illumination lens ismaintained, and the entire illumination system of a com-plex photomicrographic apparatus remains in alignment.Changing of carbons is simple and safe.Can be used on direct or alternating current. With A. C.a selenium rectifier is interposed in the circuit.

{ NOTE: The arc lamp without illumination lensand stand con be supplied separately foruse with optical benches for photomicro-graphy or micro-projection.
