An Italian public health survey

is being made under the auspices ofthe Italian High Commissariat forHygiene, assisted by the RockefellerFoundation and the World HealthOrganization, to help the Italiangovernment reorganize its publichealth services so as to take advan-tage of modern scientific methods inthe prevention of disease and themaintenance of health. Such fieldsas tuberculosis, malaria, venereal dis-eases, maternal and child care, in-dustrial hygiene and public healthstatistics are being surveyed by spe-

cialists lent to the Italian govern-

ment by WHO and the RockefellerFoundation. Among the consultantsare Julie Backer, of the Central Bu-reau of Statistics, Oslo; Luigi Car-rozzi, of the University of Geneva;Dr. Lembrez, director of BorderHealth Control for the Marseillesarea; and J. E. McCartney, of Lon-don. The survey began in June andis expected to be completed late inSeptember. Results will be reportedto the 'special commission headed byMario Cotellessa, of Italy, and J. B.Grant, director for Europe in theRockefeller Foundation's Interna-tional Health Division.

The Roscoe B. Jackson Memo-rial Laboratory will put into full ef-

fect this fall its program of coopera-tive graduate study which will makeits research facilities available with-out tuition fee to qualified graduatestudents. Credits may be appliedtowards M.D. and Ph.D. degrees in

biology, zoology, bacteriology, ge-

netics, psychology, and allied fields.Cooperating graduate schools to dateinclude Northwestern University,University of Chicago, University ofIllinois, Johns Hopkins University,Harvard University, University ofMichigan, Washington University,Cornell University, University ofRochester, Ohio State University,University of Maine, PennsylvaniaState College, and Brown University.There are also assistantships avail-able and the laboratory will aid stu-dents in securing predoctoral fellow-ships such as those offered by theNational Institutes of Health and theAmerican Cancer Society.

Abstracts of Vitamin Literature,published by the Association of Vi-tamin Chemists, is available at an

annual subscription rate of $3.00 forfour quarterly issues. The fee covers

cost of handling, printing and mail-ing; all abstracting, compilationsand editing are done on a voluntarybasis by association members. Thetwo preceding volumes are availableas long as the supply lasts. Subscrip-tions should be addressed to Irwin

Status of AAAS MeetingReservations

The early and heavy demandfor single rooms already indi-cates a potential shortage of thistype of accommodations at the116th Meeting of the AAAS inNew York City, December 26-31. There are plenty of hotelrooms but many have double ortwin beds. Miss Sylvia T. Pel-tonen, Manager, Housing Bu-reau, New York Convention andVisitors Bureau, 500 Park Ave-nue, New York 22, who is incharge of room assignments,urges that, when possible, roomreservations be placed by partiesof two or more. This also hasthe advantage of a lower costper person. Room reservationcoupons will appear in the ad-vertising pages of Science atfrequent intervals.

ELECTRONIC INTERPRETATIONSof ORGANIC CHEMISTRY

Second Edition. By A. Edward Remick. A careful review of the field, this new edition givesthe reader sufficient knowledge to employ electron theory as an aid in solving his laboratory prob-lems either in pure or applied chemistry. All reasonably well substantiated theories are ex-plained and critically analyzed. English electronic theory of organic chemistry is combined withthe American counterpart, and the electrochemical approach to organic oxidation-reduction iscovered.2nd Ed.

This latest volume of the WILEY ORGANIC REACTION SERIESpresents a thorough discussion from the preparative viewpoint of 10 important organic reactions.Laboratory procedure and likely problems are treated. Interfering influences, effects of structure,and selection of experimental techniques are covered. Among the reactions included are: theHoesch synthesis; the Cattermann-Koch reaction; selenium dioxide oxidation; and the Leuckartreaction.September 1949 446 pages $6.00

BIOLOGY of DROSOPHILAEdited by M. Demerec. This unique new volume treats in detail the anatomy, histology, anddevelopment of Drosophila. It presents the basic norm as a standard for the analysis of experi-mentally induced genetic variation and deviation, and for other physiological studies. The bookshows the histological structure of all organ-systems by means of photomicrographs and their insitu relationships by means of line drawings. Methods of collecting, shipping, culturing, feeding,and other laboratory techniques are described in practical detail.Ready in October Approx. 600 pages 251 illus. Prob. price $10.00

DIFFERENTIAL EQUATIONSSecond Edition. By Harry W. Reddick. This new edition deals with methods of solving ordi-nary differential equations and problems in applied mathematics involving ordinary differentialequations. New in the second edition is a chapter on the linear equation of second order; addi-tional material on hyperbolic functions, systems of curves, and vibratory motion; amplificationof the treatment of the motion of a weight attached to a spring; a discussion of the range of theparameter; and additional problems and figures.2nd Ed.

PHENOMENA, ATOMSAND MOLECULES

IRVING LANGMUIR

The Philosophical Library deems it a privilege to announce

the forthcoming publication of Dr. Langmuir's work PHE-NOMENA, ATOMS AND MOLECULES. The eminent scholar,winner of the Nobel Prize and one of the country's pioneers inatomic research, has set down in this volume many of his thoughts,observations and conclusions.

PHENOMENA, ATOMS AND MOLECULES exists on two

levels: The first section of the book deals with such generalproblems as "Science, Common Sense and Decency," "ScienceLegislation," "World Control of Atomic Energy."

The second part of the book deals with such technical, sci-entific problems as "Surface Chemistry," "Flames of AtomicHydrogen," "Forces Near the Surfaces of Molecules," "TheEvaporation of Atoms, Ions and Electrons from Caesium Filmson Tungsten," "The Condensation and Evaporation of GasMolecules," "Metastable Atoms and Electrons Produced byResonance Radiation in Neon," etc.

Among the many interesting, timely phases of Dr. Langmuir'sobservations are those concerning the present status and thepossibilities of Soviet Russia's scientific research. $10.00

I VERSATILE,AB BETA GAMMA

This Multifunction Instrument can be used asa radiation dosage meter or as a monitoringinstrument. It can also serve as an ore detector.

Counts Per Minute or Milliroentgens can beread directly on the three inch meter. The redscale indiicatbr MR and the black scale CPK.The maximum scale ranges are 0.02, 0.2, 2., and;20 MR or 100. 1,000, 10,000, and 100,000 CPM.

The Beta Gamma Geiger Tube has a windowthickness of about 30 mg/cm2 and will respondto all but low energy beta rays. With the remov-able shield placed over the tube, the instrumentwill differentiate between beta and gammaradiation.

Automatic Selection of the Time Constantinsures the fastest possible reading. Individualcalibration controls for each range make moreaccurate readings possible. Long-life batterieswhich are easily accessible reduce and simplifyservicing.

FULL FIELD Illumina ion

at ALL Powers

Engineered into theNew AO SPENCER Microscopes

FROM the lowest power to the oil immersion the new No. 700 Illuminator pro-vides convenient, uniform illumination that adequately fills the field withoutrefocusing the condenser. This light source has been engineered to function as anintegral part of the new AO Spencer Microscopes-yet it can be removed orattached at a moment's notice. With the illuminator in position the microscopecan be inclined at any angle or moved about the table without need for realign-ing the illuminating system. Cooling fins, heat-absorbing glass, and baffle plateall help maintain a constant temperature suitable for living specimens. Otherfeatures are: bulb with built-in ref ector, easy access to bulb, switch-in cord.
