"What a fungus aoes...how it does it...and why..."

- ~THE FUNGIAn Introduction to their Structure,

Classification, Activities, and Natural Economy

By FREDERICK A. WOLF, Professor of Botany, Duke Uni-versity, and FREDERICK T. WOLF, Assistant Professor ofBotany, Vanderbilt University.

Volume I of this reference textbook presents a thorough analysis of the develop-mental morphology and taxonomy of fungi. Volume II, representing a new andimportant emphasis, is devoted specifically to the activities of fungi and theirrelation to man's welfare. Teachers will find the two volumes excellently plannedfor use in full-year advanced undergraduate and graduate courses on the nature offungi and their activities. The emphasis on problems relating to fungus activitiesshould also prove of interest and value to students majoring in plant pathology,microbiology, forestry, and agriculture.

The authors have followed the pedagogically sound procedure of first emphasiz-ing principles and then giving the illustrative material necessary to clarify the factsinvolved in that principle. They have omitted certain little known families, havede-emphasized phylogeny, and have arbitrarily given no consideration to lichens.

Both volumes are beautifully illustrated. All explanations are given in thelegends, so that illustrations and legends supplement the text, aiding in definingterms and in providing an understanding of the general morphology of typicalgenera or species.

THE CHEMISTRY AND TECHNOLOGYOF WAXES

By ALBIN H. WARTH, Crown Cork and Seal Co.,Baltimore Md.A basic, thoroughgoing technical referencevolume covering all aspects of this highly im-

S portant subject. No other book like this isavailable. Completely documented and filledwith detailed tabular data, it covers the chemical components of waxes of alltypes. Exhaustive chapters are devoted to the natural and fossil waxes,petroleum and microcrystalline waxes and to synthetic waxes and their com-pounds. Another chapter deals with the methods used to determine thephysical constants of waxes, and the book concludes with an extremely in-formative critical review of the uses of waxes in industry. This volume standsunrivalled in its field, and will prove to be the most useful compendium ofinformation ever offered to the wax-using industries.525 Pages Illustrated $10.00

FLAMEPROOFING TEXTILE FABRICSPrepared by a Staff of Specialists under tbe Editorship ofROBERTW.

American Chemical Society Monograph No. 104

Here is the long-awaited survey of the flameproofing of textile fabrics, basedon problems encountered during the war. Divided into three general sections:(1) the fundamental mechanisms of the thermal degradation of cellulose andthe chemical or physical phenomena of flameproofing; (2) the methods em-ployed in the processing and evaluation of flameproofed fabrics; and (3) thevarious applications for flame-retarding treatments in the field of textile fab-rics. This presentation familiarizes the reader with the types of retardantsavailable, the function of these agents in the prevention of flaming and glow-ing, and the methods by which they are applied and evaluated. In additionto the results of the research project on "The Flameproofing of Army Cloth-ing," this volume includes a great deal of related information.430 Pages Illustrated $6.75

Isolation of narrow regions of the spectrum incolorimetric analysis is important.

The usefulness of photoelectric colorimeters,photometers, abridged spectrophotometers, etc.can be extended with Farrand interference filtersbecause they make possible the selection of ap-propriate spectral regions.

Farrand interference filters are characterized bytheir narrow band widths and high transmission.
