Five newbooks helpingto narrow the gapbetween scienceand humanities.Problems of Our Physical Environment: Energy -

Transportation - Pollution by Joseph Priest. Thisbook for nonscience students concentrates on thephysical aspects of such problems as energy, airpollution, thermal pollution, noise pollution, trans-portation, waste recycling, and environmental sens-ing.

Nuclear Energy - Its Physics and Its Social Chal-lenge by David Rittenhouse Inglis. The author'saim is to provide a basis for understanding boththe technical and the socio-political aspects of nu-clear energy problems - for a reader without priorknowledge of either. This book may be used asa principal or supplementary text.

Fundamentals of Air Pollution by Samuel J.Williamson. The author draws from the fieldsof meteorology, chemistry, physics, medicine,psychology, and engineering to relate the causes,evolution, and effects of air pollution. This is anintermediate-level book for scientists and engi-neers.

Genetics and Society edited by Jack B. Bresler.This interdisciplinary reader introduces the field ofsocio-genetics, as distinct from Mendelian, evolu-tionary, biochemical, and psychological genetics.The two basic questions that dominate the bookare how the human gene pool affects human soci-ety and how human society affects the humangene pool.

Western Man and Environmental Ethics edited byIan G. Barbour. This reader examines attitudestoward nature and technology that have led intothe environmental crisis and new ideas that mightlead out of it. Disciplines represented in the read-ings range from American history, poetry, and lit-erature, to city planning and computer models.

We're talking about our new solu-tions to the traditional problemswith disposable mouse cages. Ournew clear disposable cages comefully nested, yet have stackingposts to prevent jamming. Alto-gether you save time, labor costs,storage space, and shipping costs.Even with bedding in them, 100cages of our new clear, disposablemouse cages take up less than 4cubic feet, less than half the volumeof other disposable cages.

All of these features add up to asavings of 50% or more over othertypes of disposable cages. Madeof clear polystyrene, these cagesaccept standard lids and covers. Inaddition, they have molded flangesfor use in suspensiorr racks.

You also have the option of or-dering them pre-packed with thefinest animal bedding we know ofab-sorb-dri@. It's patented. (U. S.Patent No. 3,256,857.) Your re-search work will go easier - everyday-because you don't have toworry about the separate storageof the bedding material or the timeconsuming labor of filling eachcage with bedding.Another contribution to small ani-

mal care from Lab Products, acompany of experienced peoplewith new ideas in lab animal careequipment. We have them all in acatalog. For your copy, write orcall Lab Products, Inc., 635 Mid-land Avenue, Garfield, New Jersey07026, (201) 478-2535.

With the NBS Ecologen, you can now growup to four pure and separate cultures in asingle mixed culture system. The Ecologenpermits interacting cells to grow in pureculture, while the metabolites of each pop-ulation diffuse freely through filters to influ-ence cell physiology, growth, and productyield. Because each individual culture re-mains homogeneous, cell growth variablesare easily observed. The Ecologen simu-lates the natural environment by producingmany of the variations found in nature. It isideal for use in studies of soils, water oralcavities, digestive tracts, etc.
