"textbooks of choice"

Gardner's Introduction to NEUROLOGYFrom his wide teaching experience Dr. Gardner knows very well thatprinciples are of prime importance to the student beginning the studyof neurology. His aim in this new text, therefore, is to explain, toclarify, to simplify-and definitely not to confuse with a mass of un-

related anatomical data and complicated physiological events. Hepresents his material with neatness and dispatch and makes it under-standable to the student with a minimum background in biology.Basic neuroanatomy is well covered, along with the important physi-ological processes and the fundamental relationships of psychologyto the higher nerve centers.

By ERNEST GARDNER, M.D., Assistant Professor of Anatomy, Wayne University College ofMedicine, Detroit, Michigan. 336 pages with I I3 illustrations. $4.75. New.

Ranson-Clark's NEURO-ANATOMYThis book has been described as the most generally useful expositionof neuroanatomy in the English language. It is an almost indispen-sable reference source for the pre-medical course and the textbook ofchoice in the freshman or sophomore neurology course in medicalschool. The subject is considered from the dynamic, rather than thestatic point of view-emphasis throughout is on the developmentaland functional significance of structure. In this way complicatedanatomical details are made interesting and easy to understand.BySTEPHEN WALTER RANSON, M.D., Late Professor of Neurology and Directorof NeurologicalInstitute, Northwestern University Medical School, Chicago. Revised by SAM LILLARD CLARK,M.D., Professor of Anatomy, Vanderbilt University School of Medicine. 532 pages, 6j/2x9,with 4I7 illustrations, some in color. $7.75. Eighth Edition.

Twice every minute the TECHNICON PipetteWasher completes its syphon-cycle . . . seven surg-ing gallons of water to loosen and dislodgeclinging residues. Wastes are then literally sweptout of the pipettes by the violent suction set up dur-ing the brisk ten-second emptying phase.

Only the Technicon washer offers such rapidity andthoroughness, delivering in six cycles a full basket-load of immaculate pipettes (capacity 200 of 1 mlin 1 00th's, up to 1 8" long). The stainless steel

basket, proof against corrosive reagents, carriesits load of pipettes undisturbed through everystage: cleansing, washing and drying. Requires no

individual handling, no shifting from container tocontainer, practically eliminates breakage andchippage. A must for the busy laboratory: let ussend you Bulletin #6150 giving particulars.

USECarver Laboratory Press in use at TheWilliam Manufacturing Company,Portsmouth, Ohio. Operator is mold-ing tensile and tear test samples.

Mr. H. L. Gross of the Williams Com-pany describes his experience with theCarver Laboratory Press: "I have en-countered many types of adhesive prob-lems, including natural and syntheticrubber to various metals during vulcan-ization, cured rubber to metal, fabric torubber, etc. In all cases, optimum tem-perature, time and pressure require-ments were readily and accurately de-termined by using small part molds inthe Carver Press. This was a greataid in introducing production tech-niques".

STANDARD FOR RESEARCH AND DEVELOPMENTIn the development of plastics and chemical products the Carver Laboratory Press has performedessential services for 20 years. Small and powerful, it is most useful laboratory equipment for re-search and development work. The Carver Standard Accessories, all available from stock, includeElectric or Steam Hot Plates, Carver Test Cylinders, Swivel Bearing Plates, Cage Equipment, etc.Used for quick, accurate press-ing tests; research and instruc-tion work; testing single cavitymolds; preparation of samples;and even for small scale pro-duction.The Press is a complete, self-contained hydraulic unit. Ac-curately controlled pressures to20,000 lbs.; 6-inch gauge isrigidly mounted on base. Spe-cial gauges are available for lowpressure work.
