GLACIAL GEOLOGYAND- THE PLEISTOCENE EPOCH

By RICHARD FOSTER FLINTProfessor of Geology, Yale University

Here is an illuminating and interesting study that condenses and summarizesthe complex knowledge in this field-serving noVonly as a reference for facts alreadyestablished, but also indicating the areas which require further research.

Dr. Flint is well known as one of the leaders in the study of Pleistocene geology.He has written numerous articles and has studied glacial geology in Europe and theArctic regions as well as in North America. Because of the author's thoroughknowledge of the subject, you can read GLACIAL GEOLOGY AND THE PLEIS-TOCENE EPOCH with confidence that it is the authoritative source book in thefield.

As far as possible, the discussion is based on geologic rather than archeologicdata, and avoids deductions from any theory of climatic fluctuation which estab-lishes a fixed chronology. Throughout the book, the author strives to discrminatebetween inductive reasoning from field evidence and deductive reasoning fromgeneral considerations. Because of this effort, you are able to judge better thereliability of the facts presented.

"Professor Flint draws his examples from recent papers which heretoforehave received slight recognition from American geologists, and adds manyideas of his own heretofore unpublished. The approach to these subjectsis sufficiently advanced so that specialists can profit, yet the book isperfectly satisfactory (in fact, inspirational) for a first course in glacialgeology. I believe that this book will be the authoritative text in Pleisto-cene geology for many years, and I consider it one of the finest books inthe whole field of geology which has recently been produced."

FATIGUE ANDIMPAIRMENT IN MAN

By S. HOWARD BARTLEY AND ELOISE CRUTE,Dartmouth Eye Institute, Dartmouth MedicalSchool. 429 pages, 6 x 9, *5.50.

The authors combine a review of the many, types ofconventional fatigue studies and a presentation of anew viewpoint which distinguishes- between thepersonal phenomenon (fatigue) and phenomena oftissue modification (impairment). The book de-velops the thesis that fatigue pertains to organiza-tion rather than to energy expenditure, and arisesfrom frustation; not directly from activity.
