George Carey and Inez Eudora Perry offer illuminating insights into the history and milestones of astrology in the context of cellular chemistry. Thousands of years ago, the writings of Ancient Greek scholars such as Hippocrates marked the early appearance of astrology in the context of examining the body's composition. The use of this knowledge advanced over centuries, with examples of this evolution in understanding given through the book's chapters.

This book consists of two volumes, which are united in this edition. The first volume consists of short summarizing examinations of the various zodiac signs, explaining their significance. The second volume embarks on detailing the links between the astrological signs and the chemical compositions of the bodily salts. A series of analytical discussions of these syntheses is given, that the reader may fully comprehend their intricacy and depth.
