Life on Other Worlds by H. Spencer Jones

Hardcover. Condition: Very Good, Dust Jacket: Good. 1940. MacMillan Company. 1st Edition. Illustrated.

A very early book exploring the idea of life on other planets, written decades before mankind even visited the moon. The question is inevitably asked - in this vast creation is our little earth unique as the one home of life? This book presents the author's answer. Assuming life will develop whenever conditions are favorable for it, the investigation of conditions prevailing on the various planets and satellites in our solar system enables a fairly complete answer to be given.
