A complete anatomy and physiology program foryour students New 2nd Edition

Jacob & Francone: STRUCTUREAND FUNCTION IN MANBy STANLEY W. JACOB, M.D., Univ. of Oregon MedicalSchool; and CLARICE ASHWORTH FRANCONE, for-merly of Univ. of Oregon Medical School.Widely used in introductory courses that combine anat-omy and physiology, this lavishly illustrated text hasbeen revised and updated in a New 2nd Edition. Tomake a complete, well-rounded teaching program forstudents in the health sciences, an accompanying lab-oratory manual and a new set of audiovisual teachingaids are available.The text now includes new tables of muscles; new sec-tions on genetic biology, cancer, carbohydrate and fatdigestion, and contraceptives; and many new referencesand drawings. A Teacher's Guide provides referencesand an annotated list of films for classroom use.About 570 pp. About 470 figs. About $8.75. Ready April,1970. Audiovisual teaching aids: 10 35mm filmstrips ofabout 60 frames each, each accompanied by a 15-20 minutenarration on a long playing record and a printed script ofthe narration.

Individual filmstripswith records and scripts, about $15. Also available withnarration on tape.

An internationally recoggnized introductory text ofembryologj New 3rd Edition

Balinsky: AN INTRODUCTIONTO EMBRYOLOGYBy B. I. BALINSKY, Dr. Biol. Sci., Univ. of Ihe 1Wit-w atevvravrd, Johan;esburg, South Africa.

Now in a Neln 3rd Edition, this valuable text coverscomparative vertebrate embryology at the undergradu-ate level. Dr. Balinsky, a well known authority in thefield, shows the embryonic development of vertebratesby processes and by the development of organ systems.Embryolog) is interpreted broadly as dealing with onto-genetic development of animals. The author thereforeincludes such topics as regeneration, metamorphosis andasexual reproduction.This Newez 3rd Edition covers recent breakthroughs andadvances in this field. Significant new information is in-cluded on genetic control of development, the processesof differentiation, and advances in deciphering thegenetic code. The nomenclature used has been revised toconform to the recommendations of the 1970 Interna-tional Anatomical Nomenclature Committee.

About 750 pp. About 455 figs. About $10. Read) April, 1970.

New 2nd Edition

Leeson & Leeson: HISTOLOGYBy C. ROLAND LEESON, M.D., Univ. of Missouri Schoolof Medicine; and THOMAS S. LEESON, M.D., Univ. ofAlberta Faculty of Medicine.Here is an up-to-date revision of a text that succinctlycovers the three major divisions of microanatomy: cellbiology, basic tissues and systematic histology. For thisedition the authors have added many new illustrationsincluding photomicrographs of Epon-embedded sections.Other new material includes: discussions of such orga-nelles as annulate lamellae and microtubules-descrip-tions of freeze-etch and scanning microscopy-currentinformation on lymphocytes and on muscle contractionsand protein secretion.In the first part of the book, the authors cover the cell,intercellular substances, and the four primary tissuesand their specializations. The second section is devotedto histologic illumination of each organ system.Two filmstrips of 100 full-color photomicrographs keyedto the text are available as an excellent teaching aid.525 pp. 490 figs. $11. Jan., 1970. Also available: Two35mm. filmstrips totalling 100 full-color photomicrographskeyed to the text. Desktop viewer and filmstrips, $35. Film-strips separately, $15.

A comparative ftudy and history of vertebratesNew 4th Edition

Romer: THE VERTEBRATE BODYBy ALFRED SHERIWlOOD ROMER. Museum of Compara-tive Zoology, Harvard Univ.This popular text, now in a New 4th Edition, is one ofthe finest volumes available for a background course incomparative anatomy. A study of the form and functionof the vertebrate body is interwoven with embryological,histological, paleontological and evolutionary material.In this edition, coverage is truly comparative and doesnot overemphasize human structure. Function is con-sidered so that the student may understand the rela-tions of the various systems within the animal inrelation to its environment.Embryology is presented in a manner which creates anunderstanding of homology and shows the student theimportant place of the time element in various stagesof vertebrate development.The use of many full-color illustrations enhances thevisual impact of the text, particularly in interpretingnerve components and blood vessels.About 640 pp. About 415 figs. About $10.50. Just Ready.
