KAUFMAN A symposium in plasma proteins was held at the University of Illinois College of Medicine September 23- 24, under the sponsorship of the Robert Gould Research Foundation of Cincinnati. Eighteen papers were presented by investigators engaged in research in this field in one after- noon and two morning sessions.

MeCollum, and an address given by Hugues Gounelle of Paris, on some of the unexpected observations during years of un- derfeeding in France. Although the subject of the sym- posium was plasma proteins, the con- sideration of the subject was pur- posely so broad that the program included papers dealing with funda- mental aspects of protein metabolism which might not ordinarily be con- sidered as falling within the impli- cations of such a title. The pro- gram was built around the principal topics of formation, dietary rela- tionships, fractionation of plasma proteins, immunologic relationship, relation to the liver, hypoprotein- emia, tracer isotope studies in rela- tion to the plasma proteins, endo- crine relationships, and amino acid competitors. Sidney C. Madden spoke on plasma protein formation in disease states and Irving M. Lon- don on studies of rates of turnover of plasma protein in man. Frac- tionation and some of the interac- tions of the plasma protein were pre- sented by J. L. Oncley, and a discussion of the binding properties of serum proteins for small molecules by S. H. Armstrong, Jr. Tracer and isotope studies included papers by David Shemin on aspects on the bio- synthesis of amino acid and proteins, and by Paul C. Zamecnik and Ivan D. Frantz, Jr. on the use of C14- labeled amino acid in the study of peptide bond synthesis. The effect of dietary proteins on synthesis and relations between diet protein stores and plasma protein were presented by Bacon F. Chow and James B. Allison. Hypoproteinemia, particu- larly in relation to protein starva- tion in man and its clinical relation- ships, was discussed by Robert El- man and experimental studies of protein deficiency and temperature in relation to the formation of edema by M. Hegsted. Studies of the fate of intravenously injected plasma al- bumin were described by Fuller Al- bright and its metabolism in normal and undernourished individuals by Charles S. Davidson. Clinical studies of the relation of proteins to nutritional edema were presented by Dr. Gounelle. Certain immunologi- cal aspects of the plasma proteins were presented by Paul R. Cannon and Michael Heidelberger, and the effect of adrenal cortex on plasma protein formation and utilization and the physiological properties of amino acid antagonists were given by Abra- ham White and Karl Dittman respec- tively.

Typical methodsof synthesis of important compounds are emphasized.3rd Edition, November 1949 745 pages Illus. $7.50

TRILINEAR CHART OF NUCLEAR SPECIESPrepared under the direction of William H. Sullivan. A graphic presentation, in several colors,of data on all experimentally identified nuclear species known by approximately June 1949. Theportfolio contains 6 separate charts, 36" by 11". When properly assembled, the chart presentson a single continuous strip, the systematics of and physical constants data for these nuclearspecies or nuclides. Each hexagonal figure representing one nuclide holds such data as relativenatural isotope abundance, atomic mass, angular momentum, and percentage of radiation.November 1949 6 charts with instructions and cover $2.50

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 for other physiological studies. The book shows thehistological structures of all organ systems by means of photomicrographs and their in situ rela-tionships by means of line drawings. Methods of collecting, shipping, culturing, feeding, andother laboratory techniques are described in detail.

INTRODUCTION TO THEORETICAL ANDEXPERIMENTAL OPTICSBy Joseph Valasek. This new book provides a close correlation of optical theory and experi-ment by combining the principles of geometrical and physical optics with experiments in opticsand spectroscopy. In addition to theory and experiment, the book also treats the applications ofoptics in such fields as optical instruments, photographic optics, ophthalmic lenses, interferome-try, photoelasticity, spectrochemical analysis, and x-ray spectroscopy. The four sections of thebook cover geometrical optics, physical optics, radiation and spectra, and experiments.October 1949 454 pages 218 illus. $6.50

AVOID CONGESTION AND DELAYGET YOUR GENERAL PROGRAM

EARLY IN DECEMBERRegistration in advance of arrival at the 116th Annual Meeting of the

AAAS in the Pennsylvania Zone hotels of New York City, December 26-31,1949, has so many advantages that we wonder why almost everyone doesn'ttake this simple step. For instance:1. You avoid congestion and delay at the Registration Des in the hotel

foyers. All indications point to a record-breaking attendance since allof the Association's seventeen sections and subsections, and more thanfifty societies, will have sessions; also this is the first meeting in NewYork City since 1928.

2. You receive the General Program early in December in ample time un-hurriedly to decide among the events and the sessions of the societiesthat you wish to attend.

3. Your name and hotel address will be in the Visible Directory the firsthour of the first day of the meetings, since it will be posted in Washing-ton as soon as processed.

4. Advance Registrants will have the same privileges of receiving a mapand directly of points of interest of New York City, literature, radiobroadcast tickets, etc. At the convenience of Advance Registrants, thesewill be distributed from the Main Registration on the Penn Top of theHotel Statler, the location of the Annual Science Exposition,.the VisibleDirectory, and the Science Theatre. Admission to the excellent seriesof latest scientific films will be free to all Registrants.

This year, as a result of the vote of the biological societies, includingthe American Society of Naturalists, the sponsors, the Biologists'Smoker will be open only to regular registrants or those who pay aregistration fee at the time.

APPROACHES TO TUMOR CHEMOTHERAPYx + 442 pp.-7j x lOj-illuatrated-clothbound-1947 I

This volume of 41 papers by leading authorities is a comprehensive summary of the progress so far made

toward the chemotherapy of malignant tumors.

The plans for the volume were developed under the auspices of the National Cancer Institute and suchother centers -.of cancer research as the Memorial Hospital of New York, the Sloan-Kettering Institute for Can-

cer Research, and the Lankenau Institute of Philadelphia.Among the 93 contributors to the book are J. Engelbreth-Holm, M.D., University of Copenhagen.

Denmark, and ASuander Haddow, MiD., D.Sc., University of London and the Royal Cancer Institute of London,England. Members of the staffs of all the principal cancer research institutions in the United States contributedto this volume.

APPROACHES TO TUMOR CHEMOTHERAPY was not only a deliberately planned program but the con-

tributions were presented and discussed leisurely at two 5-day research conferences at Gibson Island. Maryland.After these presentations and discussions of the manuscripts they were reviewed and edited by both the Chairmanof the Publications Committee and the Editor of the volume, and all the numerous references to the cancer litera-ture throughout the world were carefully checked. However rapid the much hoped-for progress in the cancer

problem may be, this volume promises to be an important and trustworthy reference book.
