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 ml

in 1 00th's, up to 1 8" long). The stainless steel

basket, proof against corrosive reagents, carriesits load of pipettes undisturbed through every

stage: cleansing, washing and drying. Requires no

individual handling, no shifting from container to

container, practically eliminates breakage andchippage. A must for the busy laboratory: let us

send you Bulletin #6150 giving particulars.

Turner's General Endocrinology New!

New !-Written for general college students, this revolutionary text is the first to pre-

sent endocrinology as a biologic science. The subject is approached from an experi-mental rather than a clinical point of view. Attention is directed to the operation ofcoordinatory mechanisms in plants, invertebrates and vertebrates. Wherever possible,the human being has been chosen to illustrate the operation of biologic principles. Thebeautiful collection of illustrations drawn especially for this book, and the numerous

charts and bibliographies will greatly simplify the teaching of general endocrinology.By C. DONNELL TURNER, Ph.D., Associate Professor of Zoology, Northwestern University. 604 pages, 6" x 9",with 349 illustrations on 164 figures. New-Jart Ready

Physiology of Muscular Activity Edition!

New (3rd) Edition-Up-to-date in every sense of the word, the eagerly anticipated re-

vision of this highly regarded text describes the numerous and often delicate adjust-ments imposed on the body by its own activities. The applications of this physiologyof exercise to today's athletic programs are clearly indicated.

Scattered freely throughout the book are many results of recent research that are signifi-cant to an understanding of the effects of exercise. Biologists and medical men whohave anything to do with those who participate in strenuous athletic exercise will gainmuch of practical value from the book.

METHODS IN LIM[NOLOGY|By Paul S. Welch, Ph.D.

Professor of Zoology, University of Michigan

In this new book, the biologic, chemical and physical aspects of inland waters comein for intensive and expert examination.

Profusely illustrated and cleanly written, Dr. Welch's study can be turned tomany uses. While essentially a reference work on limnological methods, as itstitle indicates, the book qualifies amply as an authoritative guide for field andlaboratory work . . . as a textbook for a one-semester course . . . or as basicfoundation for research.

Do not decide for or against the book from this brief description. Examine ityourself; be the judge, yourself, as to whether or not Dr. Welch has something tosay to you. Use coupon to bring the book to you. If you decide not to keep it,vour account will be credited in full.
