OTHER WORLDS

 

 

BY GARRETT P. SERVISS.

OTHER WORLDS.

Their Nature and Possibilities in the Light of the Latest Discoveries. Illustrated. 12mo. Cloth, $1.20 net; postage additional.

No science has ever equaled astronomy in its appeal to the imagination, and recently popular interest in the wonders of the starry heavens has been stimulated by surprising discoveries and imaginary discoveries, as well as by a marked tendency of writers of fiction to include other worlds and their possible inhabitants within the field of romance.

Mr. Serviss's new book on "Other Worlds, their Nature and Possibilities in the Light of the Latest Discoveries," summarizes what is known. With helpful illustrations, the most interesting facts about the planets Venus, Mars, Jupiter, Saturn, etc., as well as about the nearest of all other worlds, the moon, are presented in a popular manner, and always from the point of view of human interestā€”a point that is too seldom taken by writers on science.

ASTRONOMY WITH AN OPERA-GLASS.

A Popular Introduction to the Study of the Starry Heavens with the simplest of Optical Instruments. Illustrated. 8vo. Cloth, $1.50.

"By its aid thousands of people who have resigned themselves to the ignorance in which they were left at school, by our wretched system of teaching by the book only, will thank Mr. Serviss for the suggestions he has so well carried out."ā€”New York Times.

PLEASURES OF THE TELESCOPE.

A Descriptive Guide to Amateur Astronomers and All Lovers of the Stars. Illustrated. 8vo. Cloth, $1.50.

"The volume will be found interesting by those for whom it is written, and will inspire many with a love for the study of astronomy, one of the most far-reaching of the sciences."ā€”Milwaukee Journal.

WILLIAM JAY YOUMANS. PREFACE

The point of view of this book is human interest in the other worlds around us. It presents the latest discoveries among the planets of the solar system, and shows their bearing upon the question of life in those planets. It points out the resemblances and the differences between the earth and the other worlds that share with it in the light of the sun. It shows what we should see and experience if we could visit those worlds.

While basing itself upon facts, it does not exclude the discussion of interesting probabilities and theories that have commanded wide popular attention. It points out, for instance, what is to be thought of the idea of interplanetary communication. It indicates what must be the outlook of the possible inhabitants of some of the other planets toward the earth. As far as may be, it traces the origin and development of the other worlds of our system, and presents a graphic picture of their present condition as individuals, and of their wonderful contrasts as members of a common family.

In short, the aim of the author has been to show how wide, and how rich, is the field of interest opened to the human mind by man's discoveries concerning worlds, which, though inaccessible to him in a physical sense, offer intellectual conquests of the noblest description.

And, finally, in order to assist those who may wish to recognize for themselves these other worlds in the sky, this book presents a special series of charts to illustrate a method of finding the planets which requires no observatory and no instruments, and only such knowledge of the starry heavens as anybody can easily acquire.

OTHER WORLDS CHAPTER I INTRODUCTORY

Other worlds and their inhabitants are remarkably popular subjects of speculation at the present time. Every day we hear people asking one another if it is true that we shall soon be able to communicate with some of the far-off globes, such as Mars, that circle in company with our earth about the sun. One of the masters of practical electrical science in our time has suggested that the principle of wireless telegraphy may be extended to the transmission of messages across space from planet to planet. The existence of intelligent inhabitants in some of the other planets has become, with many, a matter of conviction, and for everybody[Pg 2] it presents a question of fascinating
