The PACKARD ARMAC®

Scintillation Detector...

A compact, wholly self-contained liquid scin-tillation detector that can be used as a

whole body counter for small animals, as a

radioactivity counter for bulk samples offoods, soils and other materials, and as an

arm-only counter on humans.

This versatile and economical new instru-ment enables the research worker to counteven natural levels of radioactivity con-

veniently. Because of the great sensitivityand excellent counting geometry of theARMAC Detector, high counting ratescan be obtained with the administrationof very small amounts of radio-nuclides. . . only 1/100 to 1/1000 of maximumpermissible levels.A complete system consists of the ARMACDetector and a Model 410A Auto-GammaSpectrometer, both mounted on a mobilehousing. Provision is made for addition ofautomatic data read-out or ratemeter pres-

entation. Complete information can beobtained from your Packard Sales Engi-neer or by writing direct to the company.

Auxins to 1959

Les Phytohormones de Croissance.Methods, chimie, biochimie, physiol-ogie, applications pratiques. Paul-Jtmile Pilet. Masson, Paris, 1961.775 pp. Illus.

In the last 10 years the auxins havecertainly been thoroughly written up;first Soding's Die Wuchsstofflehre(1952), then Audus' Plant Growth Sub-stances (1953; ed. 2, 1959), Leopold'sAuxins and Plant Growth (1955), myL'Origine -et les Fonctions des Auxines(1956), and Linser and Kiermayer'sMethoden zur Bestimmung pflanzlicherWuchsstoffe (1957); there have beentwo full-sized symposia (in Wye, 1955,and in New York, 1959) and numeroussmaller ones, and several chapters inlarge books. All this is not to mentiona considerable number of special andgeneral reviews. Now comes Pilet (him-self an active contributor to the field ofgrowth and auxins), with a 774-pagebook that covers the literature through1959. Unlike several of the other au-thors, Pilet emphasizes pure sciencerather than horticultural uses. System-atically, he treats (in order) methods,chemistry, biochemistry, physiology,and practical applications. The litera-ture coverage is extensive and thorough;although it includes only papers pub-lished since 1937, the list (with titles)still occupies no less than 105 pages.

In some parts of the field, criticalevaluation would have been more use-ful than such complete reporting. Forexample, it is noted (page 328) that2,4-dichlorophenoxyacetic acid pro-motes the oxidation of indoleaceticacid, but it is not mentioned that thiswas traced to 2,4-dichlorophenol as animpurity. It is noted too that severalworkers using the diffusion techniquefound that the molecular weight fornatural auxin in seedlings was 306 to384, while others found 155 to 200.But, except for drawing attention to theprobable error of such measurements,

2034

no real explanation of these discrepan-cies is attempted. It is a pity, too, toperpetuate the old statement that in-doleacetonitrile gives rise to indoleace-tic acid via the amide, for this has beendisproved; the amide is neither an inter-mediate nor an effective substrate forthe enzyme.A 40-page chapter, "Other hor-

mones," treats of kinins, gibberellins,and the postulated calines. Here we findthe surprising statement (page 385):"Theoretically, it is certain that a calinecontrols (preside a) root formation,but it must be recognized that we knownothing either of its chemical structureor its biological properties, and no onehas been able to extract it or to makean analysis of its biochemical charac-ters." This seems to make the calineabout as substantial, and as useful totheory, as the luminiferous ether, andone wonders whether such faith mightnot be better tempered with a desirefor evidence.

The section on physiology contains agood discussion-of auxin transport andits complications and another of therole of auxin in tissue cultures, a re-view which, though brief, is a newand very useful departure. Pilet has anice gift for making up little tables anddiagrams, often bringing together theresults of several workers. If the dia-grams are sometimes not as easy tounderstand as a table would have been,they are, in any-event, better than adesert of text.The book is, alas, not free from the

usual misprints and misspellings, espe-cially in the bibliography, but it is veryunderstandable that the elan whichdrives one to assemble 105 pages ofreferences might well be exhaustedwhen the time 4comes to correct theproofs. - 'What a pity that Pilet's clear exposi-

tion and beautifully phrased Frenchwill be lost on so many of our studentswho no longer learn to read the lan-guage.

The combined techniques of electron microscopyand autoradiography were used for the pur-pose of differentiating radioactive from non-

radioactive particles collected on membranefilters (Millipore type AA, 0.8u pore size).Newer methods of processing the membranefilters and applying the nuclear emulsion haveresulted in an improvement in the qualitativenature of the procedure.

MeetingsPlant Phenolics

The recent increase of interest in thebiology and chemistry of the phenolicconstituents of plants becomes immedi-ately apparent on inspection of thetable of contents of many of the world'sbiological and chemical publications.However, workers in the various fieldsin which there is an interest in theplant phenolics are widely scatteredthroughout departments of botany,biology, biochemistry, chemistry, micro-biology, pharmacy, pharmacology, andforestry, in universities, research insti-tutes, government agencies, and indus-try. There is consequently almost no

common meeting place for people withsuch interests, with the result that thereis little discussion and exchange of in-formation between workers in the dif-ferent disciplines.

ln 1956 the Plant Phenolics Groupwas founded in England as an informalorgianization with the aims of promoting"the advancement of the knowledge ofphenolic and related constituents ofplants in respect of their chemistry,function, biosynthesis, effect on plantand animal physiology and pathology,and the application of such knowledgein agriculture and industry." Since itsfounding the Plant Phenolics Grouphas been very successful in achievingthese aims, holding two or three meet-ings per year. The proceedings of many

of these meetings have been published.At the 9th International Botanical

Congress in Montreal in 1959, discus-sions with various biochemists andphysiologists interested in plant phenolicsubstances led to the idea that a sisterorganization be fornied in North Amer-ica. The largest problem involved informing such a group on this continent,of course, results from the geographicalsize of North America, which wouldprohibit such a group from meetingmore often than once a year.

An organizing comnmittee consistingof T. A. Geissman (University of Cali-fornia), V. C. Runeckles (ImperialTobacco Company of Canada), andG. H. N. Towers (McGill) distributeda letter to interested persons in 1960,the response to which was so enthusias-tic as to encourage the committee tomake plans for an inaugural meeting.

This was held at Colorado State Uni-versity, Fort Collins, from 31 Augustto 1 September 1961, and took theform of a symposium on the bio-

chemistry of plant phenolic substances.The meeting was sponsored by the Na-tional Science Foundation, under thedirection of G. Johnson (ColoradoState University) and T. A. Geissman.

Papers were presented as follows:"Recent studies on the structures andbitterness of the flavonoid glycosides ofcitrus" (R. M. Horowitz, U.S. Depart-ment of Agriculture); "Biosynthesis ofplant phenols" (S. A. Brown, NationalResearch Council, Saskatoon); "Nat-urally occurring biflavonyls" (N.Kawano, University of Nagasaki);"Metabolic fate of phenolic substancesin animals" (A. N. Booth, U.S. Depart-ment of Agriculture); "Role of plantphenolics in disease resistance and im-munity" (I. Uritani, Nagoya Univer-sity); "Melanin and its formlation" (G.A. Swan, University of Durhamn); and"Estrogenic-like substances in plants"(E. M. Bickoff, U.S. Departmiient ofAgriculture).

Over 60 delegates attended thesymlposiumii, the last session of whichwas devoted to founding the PlantPhenolics Group of North America.The officers elected were as follows:president, S. H. Wender (University ofOklahoma); vice-president, L. Jurd(U.S. Department of AgriCulture); andsecretary-treasurer, V. C. Runeckles.

It was agreed at the founding meet-ing that membership be open to allpersons interested in the Group's aims,on application to the secretary, Dr. V.C. Runeckles, P.O. Box 6500, Mont-real.

WHY LIQUID NITROGEN PROVIDES THE

11 I MOST SATISFACTORY SYSTEM FOR

PRESERVING BIOLOGICAL MATERIALS

To preserve biological materials indefinitely, very low temperatures are re-

quired. Only at temperatures bclow -130°C. (2020F.) is all chemical andphysical activity reduced to a negligible level.

Only with liquid nitrogen (-196°C., -320°F.) can you obtain safe, eco-

nomical long-ter-in storage . . for months, ycars, even centuries.Liquid nitrogen does not react with the materials with which it comes in

contact. It has no effect on the pH of solutions.

The implication is ridiculous that theprinciple of adding extra phases to amnaterial to strengthen it is a logicaldevelopment of any kind of recenttheoretical thinking, let alone a fruit ofthe state of confusion that has devel-oped from the highly specific mlodelswhich have been described in metaallur-gical literature. It seems quite apparentthat the work reported by Kingervcould have been accomlplished by a

clear-thinking scientist (which Kingervis, in my opinion) with a classical pointof view on strengthening of materials,ais opposed to a view of the kind thatis arrived at by overdevelopment ofoversimplified mechanistic hypotheses.For instance, must we consider disloca-tion theory the basis for the followingstatement by Kingery: "As found fromzlong experience with metals, plastics.and ceramics, the kinds of alloys whichare most useful under these conditions,ire those made with stable second-phase additives having useful proper-ties"? The most useful two-phase mate-rial discuLssed by Kingery can be derivedaind explained on a purely classicalbasis, with no regard whatsoever fordislocations, whether edge or screw.

It is interesting to attempt to followKingery's conclusions about the virtuesof adding glass fibers. First of all, it isnot clear how fibers will linmit the stressinduced in ice to a m71inimlum value.Second, I fail to see in Kingery's TableI the more than tenfold increase instrength from Fiberglas additions thathe finds.

In his enumeration of requirementsfor fibers to be effective in reinforcingmaterials, Kingery has omitted the thirdessential feature of the system: goodadhesion must be achieved at the fiber-matrix interface. Again, no knowledgeof dislocations is required to derive this.

JAMES E. MCNUTTWilmiingion, Delaivare

McNutt's opinion that dislocationtheory has been of marginal "useful-ness" for developing improved alloys isac minority, but not uncommon, opinionamong metallurgists. It is probablytrue that the scientists who have con-tributed most to dislocation theory havecontributed least to alloy development.The argument that technological im-provements would have been made withequal facility without a background ofunderstanding based on dislocation

theorv is difficult to refute when, infact, there are few, if any, competentalloy developers unaware of disloca-tions. At the present time, dislocationsare a significant part of the "classicalpoint of view on strengthening ofmaterials."

I think there can be no dispute aboutthe utility of dislocation theory for'rationalizing observed strengths." Aglance through any contemporary sym-posium volume on fracture, deforma-tion, or mechanical properties makes itclear that dislocation theory forms thefoundation for any science (as opposedto technology) of mechanical behaviorof materials.

Medical Instrumentation

Duncan A. Holaday is to be com-mended for his excellent survey "Wheredoes instrumentation enter into medi-cine?" [Science 134, 1172 (1961)]. Heperhaps was more harsh in some of hiscriticism than someone outside themedical profession could be. However,his solutions to the dilemma-to trainphysicians in engineering and to bringengineers into hospitals-pose furtherdilemmas.

Let us consider the first problem:Where does a physician get such train-ing? Only one or two institutions offer atraining program honestly aimed atinstrumentation. The several biomedicalengineering programs offered elsewhereare directed toward developing an engi-neer with cross-disciplinary training forresearch-not a man who is a specialistat measurement.Measurement systems are largely

electrical or electronic, so one wouldexpect to find electrical engineers withthe necessary training. However, instru-mentation is an unwanted by-product inmost university electrical-engineeringdepartments. The trend is toward train-ing physicists for applied research, andinstrumentation is no longer "respect-able."

In any attempt to bring the engineerinto the hospital there are two distinctobstacles. First, nonengineering ad-ministrators generally have little under-standing of what an engineer is, be-yond "someone who knows about elec-tronics, radios, and so on." Conse-quently, in all but a few hospitals the22 DECEMBER 1961

salaries for electronics personnel are setat the level of the local radio-TV repairman-usually less than a recent engi-neering graduate receives. If one wishesto attract a man with several years' ex-

perience who can bring valuable, up-to-date techniques into the hospital, one

must offer a professional salary.I feel that most engineers interested

in a career as a specialist in medicalinstrumentation will be research-typemen who will want to conduct theirown research programs in addition totackling measurement problems forphysicians. Consequently, a second bigquestion is raised: Is the engineer to bea professional staff or faculty memberor just a technician? Few capable, ex-

perienced engineers will accept thelatter position.

It is obvious that there are few engi-neers with the background to makemedical judgments; however, a basicproblem of instrumentation is that offinding how to obtain significant meas-

urements. We already have too many

gadgets produced by well-meaning engi-neers who don't know the medical prob-lems, or by medical personnel whoasked for a device but did not authorizean engineering study of the over-allmeasurement problem.No real advances in medical instru-

mentation will be possible until bothphysicians and engineers consider eachother specialists and are willing to worktogether on a professional level. Itseems apparent that either of Holaday'ssolutions will require a re-education ofboth physicians and engineers.

Sias is undoubtedly correct in hisconclusion that both physicians andengineers will need training in theother's art before they are able to worktogether effectively.

Programs to indoctrinate engineers inbiomedical areas are beginning toappear. It is true that the emphasis istoward research rather than appliedinstrumentation, and toward biophysicsand bionics (the application of lifeprocesses to the solution of engineeringproblems) rather than medical engi-neering. Efforts in these areas should,nevertheless, generate mutual respectand, in the course of time, solutionsto more immediately practical problems.

Those who have the greatest stake inmedical instrumentation might givesome thought to helping. Physicians

and hospital administrators could prof-itably make space for engineers towork in their laboratories. Instrumentcompanies would be well advised to re-

move their development engineers fromfactory drafting boards, where the engi-neers continue to make conceptual mis-takes in designing instruments for use

in patient care, and accept opportunitiesto place these engineers in hospitalswhere the latter can witness the causes

of earlier failures and participate infield trails of new attempts.

Selling Methods

Out of profound respect for Scienceand its readers, many of whom are alsocontributors and advisers to Encyclo-paedia Britannica, I am compelled tocomment on your editorial "The com-

pany they keep" [Science 134, 75(1961)].The editorial gives the strong-but

erroneous-impression that a recentFederal Trade Commission order affect-ing Encyclopaedia Britannica deals withcurrent selling methods. This is nottrue.The original action by the FTC on

which the citation was based was takenin May 1958 and involved complaintsreceived by the FTC prior to that time.Our salesmen have always been in-

structed, under penalty of immediatedischarge, not to use the kind of ir-regular sales presentation that led tothe FTC complaints. As soon as theseindividual complaints were brought toour attention, we took immediate stepsto insure against their recurrence.

HARRY E. HOUGHTONEncyclopaedia Britannica,Chicago, Illinois

Here is the sequence of Federal TradeCommission documents on which myeditorial on the Encyclopaedia Britan-nica, Inc., was based: (i) a "Complaint,"filed 5 May 1958, serving notice to theBritannica company to appear at FTChearings; (ii) an "Initial Decision," filed30 August 1960, ordering the companyto "cease and desist" from certain salespractices; and (iii) a "Final Order,"filed 16 June 1961, ordering the com-

pany to "cease and desist" from certainsales practices, following the company'sappeal of the initial decision.-J.T.
