However, practical considerations have not been neglected. They include advice on choosing the mobile and stationary phases, a discussion of the relittion of chromatography t o a larger schema of analysis, procedural steps, and hints to one "with little or no experience in chromatography." It should be stated that with d l such emphssis on guiding principles, the book is well stocked with specific illustrations, usually given to makes point clear. The author has been selective, rather than exhaustive, in his list of 1081 references, many of which appeared in 1056. Of the total, more than 30 are to publications by Dr. Cassidy and c*workers. Some 18 references are to personal communications from as many sources, further attesting to the degree with which the author is aware of current work. The publishers, editor, and author are all to be congratulated on bringing out aa importmt a. contribution as this. There has long been a need for taking chomatography out of the realm of "art," and eomvorting it into a "scienoe." This book meets a substantial portion of that need. JOHN W.

Tho Journal, however is not an sutabiography. Neither is it the story of fiberglass, but a long letter in many short chapters to a "Dear Reader I don't know but hope t o find somewhere," I t is a highly personalized and philosophic rcrord of the human side of scientific and industrial research as well as philosophical reflections upon the resources of science and the science of human happiness. He defines a seientieian as 8. "kind of butterfly, Living out of the flowers of other people's gardens, ignorant among experts and brainy in the common crowd, half way between an artist and a scientist and despised by both!' The entries in his Journal follow the trend of his thoughts without consideration of time: and the seooe and content of his thoughts range fro& econophysirs, technicians, and life in the laboratory to Manhattan projects, rockets, and pipelines in Arkansas; from a promenade in Tuscany and Trader Horn a t Princeton to the science of Gsndhi and Leonardo da Vinci. The Journal is written, according to the author in a "holiday mood," meaning "living in the present, forgetting the past, and not worrying about the future."
