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.
