THIS is why, in so many industries, spectrographic analysis issupplanting slower, and often less accurate, methods . . .and why,also, so many educational institutions are installing B & L Spectro-graphic Equipment. Students thus trained are better prepared forthe methods and tools industry will require them to use.

The B & L Small Littrow Spectrograph (illustrated) is an idealinstrument for educational use. Simple in design, ruggedly con-structed, and economically priced. Write for complete details toBausch & Lomb Optical Co., 642 St. Paul St., Rochester, N. Y.

ARCHITECTUREOF THE fEART0HBy REGINALD ALDWORTH DALYSturgis Hooper Professor of Geology,Harvard University

HIS is a very readable account ofthe make-up of the earth which

affords a readily visualized picture ofour planet. It is based on a newtheory derived from forty years ofresearch in the field, supplemented bycontinuous study of the world's geo-logical and geophysical literature. Itis the first book of its kind to give dueweight to the latest and best resultsof investigations in both geology andearth physics. The book presents anearth-model, analogous to the modelatom of physics and the model star ofastronomy, to illustrate the essentialcharacteristics of the planet called theearth. This is one of the volumes inthe Century Earth Science Series, ofwhich Kirtley F. Mather, Ph.D., Pro-fessor of Geology, Harvard University,is the general editor.

Life, Heat, and AltitudeBy DAVID BRUCE DILL

In this fascinating book the author deals withlife in high temperatures and at great heights."A considerable amount of scientific and eventechnical information is presented, but the styleis so readable and there are so many interestingillustrative stories that the layman as well as thescientist will enjoy the book."-Science NewsLetter. "Recommended both for the technicalinformation presented and as an interesting ac-count of the living organism under stress."-Journal of the Aeronautical Sciences.

ELEMENTS OF PHYSICSBy ALPHEUS W. SMITH

Professor of Physics, Ohio State University

New Fourth Edition

775 pages, 6 x 9, illustrated. $3.75Maintaining its position as a leading text in the field of elementary general physics, the new fourthedition of this eminently successful book has in the past five months been adopted by over fifty collegesand universities. Representative institutions in this rapidly growing list are:

Colorado State College Purdue UniversityConnecticuit State College Tulane UniversityDartmouth College U. S. Military AcademyUniversity of Kansas Virginia Polytechnic InstituteOhio State University Yale University

In this revision, as in earlier editions, a limited number of physical principles are presented in such a way as to en-courage students to form clear and distinct physical concepts and to develop a capacity for seeing relations betweenphysical principles. Many changes have been made to improve the presentation and to bring the material abreastof current developments. The problems have been entirely revised and rearranged.
