The Living Clocks

8vo. 385pp. from front flap: "One of the most exciting developments in science today--the discovery of the "biological clocks" that govern the behavior of all life from barnacle to man, and link each of us with the "beat" of our spinning planet--is here for the first time comprehensively opened up for the layman. In his pioneering and fascinating book, Ritchie Ward unfolds the dramatic researches that have made the living clocks a central concern of today's biologists seeking to understand our total environment." #00772. very good: slightly bumped corners, writing on FFEP, some fade to red top stain of text block. text clean, binding tight and square. very good: edge wear, rubbing, some creasing in flaps, NOT clipped ($8.95).
