Every instructor recognizes the importance of the text-book as an integral part of the teaching program. AtSaunders, therefore, constant vigilance is maintained tomake certain that our new books and new editions mea-

sure up to the highest standards-that they perform withgreatest efficiency the important function expected ofthem by the teacher. Specific examples of this policyare the four books on bacteriology described below.

McClung's Bacteriology Laboratory ManualNew Book, Ready May 3rd-This new manual is of special interest since it is one ofthe most important teaching tools of its type to be published. It especially fits generalcollege course requirements and is readily adaptable to courses of various lengths andwith a variety of emphases. Sixty-one experiments are given-each one complete withinitself, an obvious advantage to the teacher who desires full freedom in his laboratoryprogram. Designed to help the student appreciate the biological importance of theresults of the experiments, the material in this manual has been proved highly effectiveover a period of years in the author's own classes.By L. S. MCCLUNG, PH.D., Associate Professor of Bacteriology, Indiana University. 115 pages, 8%" x 11",Wire-0 Binding. Just Ready

Greaves' BacteriologyNew (5th) Edition-Edition after edition,this book continues as one of the preferredtexts of elementary bacteriology.BY JosEPH E. GREAVES, M.S., PH.D., Professorof Bacteriology, Utah State Agricultural College;and ETHELYN 0. GREAVES. M.S., PH.D., Utah StateAgricultural College. 613 pages, 5¼" x 7%",with 169 illustrations. $4.00.

Frobisher's BacteriologyThird Edition-Devoted to sound, broad

and unspecialized teaching fundamentals,Dr. Frobisher's text is unsurpassed.By MARTIN FROBISHER, JR., S.B., Sc.D., F.A.A.A.S.,F.A.P.H.A., Associate Professor of BacteriologyThe Johns Hopkins University. 824 pages, 5% x

7%", with 398 illustrations. $4.00.

Jordan & Burrows' BacteriologyNew (14th) Edition-As one of the most complete and all-inclusive texts of bacte-riology available, this book gives a detailed presentation of each type of bacteria, bothpathogenic and nonpathogenic. Principles are clearly set forth and then the studentis shown how they apply in everyday problems in health and disease. The New (14th)Edition is the result of a complete rewriting and revamping, and from this revision hasemerged a truly modern and highly practical text.

SPEEDOMAX RECORDERTURNS SPECTROMETERINTO SPECTROGRAPH

Photos Courtesy Physics Dept.,Ohio State Univ.

In the Physics Dept. Laboratories of Ohio State University,as in many other labs, infra-red absorption measurements are

now being recorded by means of a Speedomax high-speed Re-corder. The Department has dispensed with hand-drawncurves of these measurements, because Speedomax recordsare so quickly and automatically obtained; so accurate anddependable.

The Speedomax is the L&N high-speed potentiometer re-

corder in which the balancing mechanism is electronically con-

trolled. Its speed is such that the pen crosses the chart inabout 12 seconds. To record infra-red absorption, the user

has only to provide an amplifying link between the Recorderand the radiation receiver of his own spectrometer.

If you are interested in infra-red recording, an L&N engineerwould be glad to discuss Speedomax as applied to your specificproblem.

This Speedomax record is only A actualsize, yet note great detail. Curve isrotational line of 10-micron absorption

band in spectrum of NH3.

The book serves as a comprehensive guide to the chro-mosome literature bearing on genetical matters. Entirechapters are devoted to such fundamental subjects asstructure of mitotic chromosomes, salivary-gland chromo-somes, structural rearrangements and meiosis; othersbear on special problems connected with parthenogenesis,male haploidy, and hybrid sterility. The always inter-esting subject matter is presented in stimulating and,easily readable form. In a second printing, some minorerrors and inconsistencies should be eliminated.

Modern plastics. Harry Barron. New York: Wiley, Lon-don: Chapman and Hall, 1945. Pp. xv + 680. (Illus-trated.) $7.50.This book, as the author notes in his Preface, has been

written for the reader with a modest scientific or engi-neering background who wishes to obtain an over-all viewof the plastic industry. In line with this thought, thebook covers all the well-known basic plastics, emphasizingtheir requisite raw materials, manufacture, processing,and applications. The nine chapters on phenolic plasticscover the phenol formaldehydes, the urea formaldehydes,and the melamine formaldehydes. Special emphasis isplaced on the methods of polymerizing and details ofmolding, casting, and laminating. The five chapters oncellulose plastics are concerned with cellulose nitrate,cellulose acetate, and ethyl cellulose. Of particular inter-est is the description of the injection molding process.The vinyl resins are well covered, with much attentionbeing given to applications. Brief but excellent chapterson plasticizers and the extrusion process are included.Polyamide plastics, alkyd plastics, and casein plastics areeach discussed. High-frequency heating methods, analyt-ical tests, and physical tests are briefly considered.While the book has not been written for the specialist

in plastics polymerization, there are several very gooddescriptions of the polymerization process both forthermoplastic and thermosetting materials. The authorsucceeds very well in presenting an over-all picture ofplastics chemistry and plastics technology. Although theauthor is an Englishman, most of the references are toAmerican concerns and literature. However, enough ofGermany's and England's contributions are present togive the book a cosmopolitan flavor.The author makes no pretense of including any up-to-

the-minute developments, and such topics as allyl plasticsand silica plastics are absent. The newer developmentsin alkyds and low-pressure laminating are not treatedadequately in the light of present knowledge. For Amer-ican readers, the author's dependence on British testingprocedures is unfortunate.

All in all, however, the book can be well recommendedas covering the entire field in an adequate manner.
