Englewood Cliffs, NJ: Prentice-Hall, Inc., 1972. 1st Edition. Octavo, publisher's ochre cloth, spine stamped in blue, original illustrated dust jacket.
First edition of this comprehensive exploration of "astrological birth control" by best-selling paranormal duo Sheila Ostrander and Lynn Schroeder. Employing the theories and methods of Slovakian psychiatrist Dr. Eugen Thomas, this (avowedly) medically researched study asserts that "biological rhythms" can be calculated from a woman's birth time. This history and guide to celestial fertility was a follow up to the best-selling Psychic Discoveries Behind the Iron Curtain (1970), in which the authors claimed that the Russians were on the verge of major parapsychological advancements, and which included a brief section describing Jonas’s revelatory natural conception method. Although the popular imagination continues to regard these ostensibly breakthrough discoveries as pure quackery, Jonas’s theories continue to find support in astrological literature to this day. Illustrated with black-and-white diagrams and tables; with a guide to determining your own "cosmographic" birth chart, and an index. Bookplate to front endpaper. Light sunning to top edges of cloth; unclipped dust jacket with moderate chipping to spine-ends and edges. Very good. Item #3033
