Newly Published BooksWEATHERWAX'S PLANT BIOLOGYDr. Weatherwax's treatment of elementary botany is scholarly, yet fully with-

J\EB 14 in the grasp of the student for whom it is intended. Difficult subjects aresimplified without, however, loss of their scientific import. He has selectedplants with particular regard for their geographic significance. The physio-

logical and ecological viewpoints are stressed in keeping with modern trends in teaching.Dr. Weatherwax gives practical assistance to the teacher and student alike-a feature warmly re-ceived. An excellent Summary concludes each chapter. Subheadings are extensively used. AGlossary of some 400 terms, with an explanation of Latin Prefixes, is included, and both the old andnew classifications of plants are given. There are 417 illustrations on 182 figures.By PAUL WEATHERWAX, Professor of Botany, Indiana University. 455 pages, 6" x 8%", with 417 illustrations on 182figures. $3.25

MICRO OBJECT MARKER, Sheaff, A.H.T. Co. Specification, foruse either as a circle engraver or as an object locator by the substitu-tion method without marking the specimen. See Philip Atlee Sheaff,"Microscopic Localization, A Rapid and Accurate Method," New YorkMedical Journal, July 17, 1915.

Consisting of the Marker with standard society screw for insertionin place of the objective on a microscope of any manufacture, with cen-tering screws, safety spring, adjustable tungsten carbide stylet A, in-terchangeable fine steel needle with holder B, and metal guide C formicro slides for localizing the desired portion of the specimen in accord-ance with the author's technique.

In the Sheaff method an ordinary micro slide, which has been smoked in a match flame or shellacked,is placed on the microscope stage in the exact position of the specimen slide by means of the guide C ora mechanical stage, after the portion of the specimen to be localized has been brought to the center ofthe microscope field. A circle corresponding with the point or object localized is scribed on the ordinaryslide, which is then labeled and stored for identification.

To relocate the area of specific interest, the procedure is reversed, i.e. the encircled area of the masterslide is oriented and focused by means of a low power objective and the specimen slide is then substi-tuted. The substitution method is particularly useful for specimens mounted without cover glass, as iteliminates scratching or otherwise marking the specimen itself.

When sending your next orderfor dissecting kits, instead ofordering your sets "same as hadpreviously" we urge you to changeyour specifications for your regu-lar scalpel to the Clay-Adams Co.No. B-300 JUSTRITE Replace-able Blade Scalpel as illustrated.

Here is the reason ... Practicallyall scalpels require a considerableamount of skilled hand labor-thesame labor urgently needed formaking Surgical Instruments forWar and Civilian needs.

Recently we developed the JUST-RITE Scalpel which is almostentirely machine made by modernhigh speed production methods-thus helping along the productionof Surgical Instruments. ThisScalpel, however, is not inferior,but offers definite advantagesover the conventional style ofscalpels, the same advantages thathave resulted in the almost uni-versal adoption of replaceableblade scalpels by Surgeonsthroughout the World. A fewsimple motions and the old bladeis replaced by a new, razor edgedblade, at a cost of less than tencents each. Naturally, JUST-RITE Scalpels are not as care-fully finished as the scalpels thatSurgeons use; the cost would notbe in keeping with student needs.

Please specify these scalpels onyour next order. In doing so, youwill be getting a very satisfactoryinstrument and at the same time,aid in the effort to conserve ma-terial and labor more vitallyneeded for other purposes.THANK YOU.

NEW G-E MODEL CA-6 BERYLLIUM WINDOW

X-RAY TUBE SPEEDS UP DIFFRACTION STUDIESi nn.

9III

CHROMIUM IRON COBALT NICKEL COPPER MOLYBDENUM

LINDEMANN GLASS WINDOW X-RAY DIFFRACTION TUBE

G.E MODEL CA-6 BERYLLIUM WINDOW DIFFRACTION TUBE

THOROUGHLY TESTED - G-E perfected the ModelCA-6 beryllium window x-ray diffraction tubeearly in 1941, and the first commercially avail-able model was installed in the laboratory of a

leading automotive manufacturer in August, 1941.The performance records of this and other CA-6tubes back up these facts:

SPEEDS UP STUDIES-The Model CA-6 has a trans-mission factor, in the range of wavelengths forwhich these tubes are generally used, which is fromsix to ten times that of Lindemann glass windowtubes. Typical normal exposures can be made withthe CA-6 beryllium window tube in approximatelyone-seventh to one-tenth the time required byLindemann window tubes.

INCREASED TUBE LIFE-The increased radiation out-put of the CA-6 tube in itself effectively serves tolengthen tube life since it permits a greater numberof exposures within a given time. In addition, itsberyllium window is not susceptible to corrosionand x-ray deterioration.

FACTS ABOUT THE CA-6 TUBE-The G-E Model CA-6tube is constructed with two beryllium windows inline with the long axis of the focal spot. The win-dows are protected by a bakelite shield having highconductivity so that the shield may be operated atground potential. The overall length of the tube isapproximately 28 inches, and the diameter of thex-ray shield, the thickest portion of the tube, is 3 2

inches. Target materials immediately available forwar production use include copper, cobalt, iron, andchromium. Molybdenum, nickel, tungsten and othermaterials are available on special order.

For complete information about the new G-E ModelCA-6 tube, write or wire, today, to Dept. R68.

THE AMERICAN ASSOCIATION FOR THEADVANCEMENT OF SCIENCE

THE TWENTY-SIXTH ANNUAL MEETING OF THE PACIFIC DIVISION

Edited by Professor J. MURRAY LUCKSECRETARY

THE twenty-sixth annual meeting of the PacificDivision, American Association for the Advancementof Science, was held at Salt Lake City, Utah, duringthe week of June 15, 1942. The meetings extendedover six days.

It was a notable week and an occasion deservingof record. Despite the exigencies of war and thepressing obligations of an unparalleled emergency,

almost 400 scientists of the far western states were

able to gather together for the purpose of friendlyintercourse and the ever-necessary exchange of in-formation from many fields of scientific research.The meetings were of a particularly high quality

throughout. General sessions commenced on themorning of June 15 with a symposium on "The GreatBasin, with Emphasis on Glacial and Post-GlacialTimes," in which three papers were presented by men

whose studies have been largely centered upon theproblems under discussion. The three papers were

as follows: "The Geological Background," Dr. Eliot

Blackwelder; "The Zoological Evidence," Dr. C. L.Hubbs and Dr. R. R. Miller, and "Climatic Changesand Pre-White Man," Dr. Ernst Antevs. The paperspresented were of great interest, and it was thoughtby many that this symposium was one of the finest inthe history of Pacific Division meetings.
