That's right! For a man, age 30, the annual premium fora 20-Year Home Protection policy providing $50,000 initialamount of insurance is $159.00. The first-year dividend, basedon our current dividend scale, is $61.50, making a net pay-ment of $97.50. Dividends, of course, are not guaranteed.

The Home Protection plan is level premium Term insur-ance providing its largest amount of protection initially, re-ducing by schedule each year to recognize decreasing insur-ance needs. This is just one example of the many low-costTIAA plans available.

THE PURINESTheory and ExperimentProceedings of an International Symposium held in Jerui-salem, April 4-8, 1971edited by ERNST D. BERGMANN, Department ofOrganic Chemistry, The Hebrew University, Jeru-salem, Israel, and BERNARD PULLMAN, Universitede Paris, Institut de Biologie Physico-Chemique(Fondation Edmond de Rothschild), Paris, FranceFrom the Editors' Preface:"The Fourth Jerusalem Symposium has been, in asense, a continuation of the second, which dealt withthe quantum aspects of heterocyclic compounds ingeneral. It was at the Second Symposium that the veryspecial position of the purines became clear: they arenot only the most important heterocyclic systems, butthey have also been studied by more quantum-chem-ical calculation methods than any other class of or-ganic compounds. These studies, having given us goodinsight into the physical and chemical properties ofthe purines, also offer us an opportunity to evaluatethe relative virtues of various theoretical methods bycomparing their results with experimental data. Ittherefore seemed indicated to devote a special Jeru-salem Symposium to the theoretical and experimentalaspects of the purines. Indeed, the breadth and depth.of information that was provided by the Symposiumexceeded our expectations. In view of the fact thatsome aspects of the chemistry and quantum chem-istry of the purines have been clarified, and someproblems sharpened by the discussions that followedeach paper, we have included the discussions in theseProceedings, though in a somewhat abbreviated form.Thus, we hope that the contents of the book justifyits title."1972, 614 pp., $20.00

INSECT JUVENILE HORMONESChemistry and Actionedited by JULIUS J. MENN, Stauffer Chemical Com-pany, Agricultural Research Center, Mountain ViewCalifornia, and MORTON BEROZA, Entomology Re-search Division, Agricultural Research Service, U.S.Department of Agriculture, Beltsville, MarylandThe detrimental side effects of some persistent insecti.cides on non-target organisms and on the ecosystemshave spurred the development of more selective meansof insect control. One possibility has captured theimagination of many scientists: deranging insectgrowth by means of juvenile hormones (JH)-thevital growth-regulating chemicals in insect meta-morphosis-and their analogs (JHA). At a Sympo-sium on the Chemistry and Action of Insect JuvenileHormones held in Washington, D.C., September 12-17,1971, eminent scientists from universities, govern-ment, and industry were invited to present and dis-cuss their latest findings in the field of JH and JHAchemistry and Biology. This volume presents the pro-ceedings of that Symposium. It summarizes what isknown about JH and their analogs, their chemistry,their biological effects and mode of action, their bio-chemical fate in tar-get and non-targetorganisms, and theirenvironmental sta-bility, As a result, ;the book providesa multidisciplinaryfoundation for fur-

ther research on theaction of JH andJHA. _ _ _1972, 352 pp., $12.00

The Shandon-Elliott Varistain 23 Automatic Slide Stainer accelerates outputby eliminating errors and maintaining unvarying standards in preparing Papstains and H & E stains. Skilled technicians are released for other more

important and rewarding work, improving overall productivity.This slide stainer-holding up to 48 slides-can be programmed to dupli-

cate your staining procedure precisely, including a running water positionwherever desired. A special timer is provided for differentiation used in

regressive staining procedures which can be set as low as one second. The

machine illustrated incorporates 23 stations. An 8-station model and 12-
