This book, free from pedantry and scientific jargon, contains what, essentially, is a comprehensive college education in all the natural sciences. Written with enthusiasm and freshness which will infect the reader, it ranges over every aspect of natural science--from microscopic life to the study of man, sea life to problems in human culture. Strict boundaries between the sciences are dispensed with, the author drawing relationships from his vast body of material. To those with even a remote interest in the natural realities of life, this book is recommended as a one-volume library.
