FIRST AIDR

SYRINGE:

IV

If you have a sick syringe,let us fix it up as good as new.Whatever your problem...a Smbent plunger, a broken needle,worn Teflon tips, or in some I^ 4cases broken glass barrels... Rwe can probably repair yoursyringe and recondition it fora lot less than the cost of anew s e yringe.

Just send us your syge.ge.We'll inspect it to determinethe extent of repair necessaryto bring it back to "first class" _working order. If you'd like,jyou may request a quotationbefore we start the work. But,just for a rough idea, here aresome typical repair costs: anew plunger for a 700 syringe-$6.00, a new needle for a700 syringe-$6.00, a newplunger wire for a 7000 syringe-$2.50.

And, there are several repairs you can make in thefield. The repair parts are listed in our catalog.You can also get a Needle Cleaning Kit with special

wires and cleaning solution to keep the inside of yourneedles clean, insuring their accuracy and prolonging

the life of your syringe. The kithas 50 pieces of tungsten Wire,70 cc of concentrated clean-ing solution, complete instruc-tions, and sells for only $21.00.

If you want to have us re-store your damaged syringe,just send it to Repair Depart-ment, Hamilton Company, PO.Box 10030, Reno, Nevada89510 (via parcel post) or4960 Energy Way, Reno, Ne-vada 8951 0 (via UPS or othersurface or air freight). Pleaseindicate if a quotation is re-quired. Syringes contaminatedby radioactive materials, in-fectious agents, or other ma-terials constituting a healthhazard to our employees maynot be returned.Who knows, maybe a 50¢

Teflon ferrule will bring yourprecision back to life, or $2.50

plunger wire for your 7000 syringewill make it work like new again, or we can refit a newplunger to your 700 syringe barrel for only $6.00.It's worth a try.

SEARCH AND DISCOVERYA Tribute to Albert Szent-Gy8rgylEdited by BENJAMIN KAMINER

This volume is dedicated to Albert Szent-Gy6rgyi andstems from a symposium, "Search and Discovery," heldin his honor at Boston University School of Medicine.The contributors are leading researchers in their respec-tive fields, and five are Nobel Laureates. The papersencompass the fields of Szent-Gy6rgyi's major contribu-

tions and interests: metabolism, vitamin C, molecularmechanisms and control. of muscle contraction, molecu-lar and submolecular biology, cell growth, and cancer,as well as the interrelationship of science and society.1977, 368 pp., $21.50/£15.25 ISBN: 0-12-395150-X

A New Academic Press JournalECOTOXICOLOGY AND ENVIRONMENTAL SAFETYEditors: FREDERICK COULSTON and FRIEDHELM KORTE

Ecotoxicology and Environmental Safety publishesstudies of the biologic and toxic effects caused bynatural or synthetic chemical pollutants to ecosystems,whether animal, plant or microbial. The editors are par-ticularly interested in reports about the entry and fate ofchemicals in the biosphere and reports of qualitative andquantitative studies of the toxic effects of chemical pol-lutants and their importance on man. Articles using thetechniques of analytical chemistry, histochemistry, phar-macology, pathology and immunology applied to chemi-

cals arising from industrial effluents, fuels, industrialproducts, discharges into surface waters, effects of me-teorological factors, radiation and catalytic actions onchemicals and metabolic transformation, are welcomed.Short review articles of general interest to toxicologistsare also included.

GeoJournal

International Journal for Physical, Biological andHuman Geosciences and their Application in En-vironmental Planning and Ecology

* The New Journal in English* In the Field of Bio-Geo-Sciences

GeoJournal treats unresolved questions in the widerange of bio-geo-sciences. GeoJournal is oriented tomodern research results and sets the pace for thedaily work of scientists.

GeoJournal focuses in environmental planning andthe areas of conflict between ecology and economics.

GeoJournal appears in volumes based on one centraltheme. The first two issues will deal with the problemareas of North Sea Oil and freight shipping.

GeoJournal enables its readers to make substantivedecisions and to evaluate critically the decisions ofothers.

GeoJournal reveals methods which may lead to suc-cessful control of our threatened natural and socialenvironment. A particular emphasis in this respect isthe goal of pooled economic resources.

GeoJournal is directed to all scientists-whether theybe engaged in research, teaching, industry, and /oradministration of institutes, libraries, and national andinternational organizations.

GeoJournal is particularly interesting for specialists ingeology, oceanography, meteorology, biology, eco-nomics, transportation, urban ecology, and cartogra-phy
