Introductory
The following pages were originally prepared in the form of a course of Lectures to be delivered before the Lowell Institute, of Boston, Mass., but, owing to the unexpected circumstance of the author's receiving no invitation to lecture before that institution, they were laid aside shortly after their completion.
Receiving an invitation from the trustees of the Vallecetos Literary and Scientific Institute, during the present summer, to deliver a course of Lectures on any popular subject, the author withdrew his manuscript from the dusty shelf on which it had long lain neglected, and, having somewhat revised and enlarged it, to suit the capacity of the eminent scholars before whom it was to be displayed, repaired to Vallecetos. But, on arriving at that place, he learned with deep regret, that the only inhabitant had left a few days previous, having availed himself of the opportunity presented by a passing emigrant's horse,—and that, in consequence, the opening of the Institute was indefinitely postponed. Under these circumstances, and yielding with reluctance to the earnest solicitations of many eminent scientific friends, he has been induced to place the Lectures before the public in their present form. Should they meet with that success which his sanguine friends prognosticate, the author may be induced subsequently to publish them in the form of a text-book, for the use of the higher schools and universities; it being his greatest ambition to render himself useful in his day and generation by widely disseminating the information he has acquired among those who, less fortunate, are yet willing to receive instruction.

Lectures on Astronomy—Part I
CHAPTER I
The term Astronomy is derived from two Latin words,—Astra, a star, and onomy, a science; and literally means the science of the stars. "It is a science," to quote our friend Dick (who was no relation at all of Big Dick, though the latter occasionally caused individuals to see stars), "which has, in all ages, engaged the attention of the poet, the philosopher, and the divine, and been the subject of their study and admiration."
By the wondrous discoveries of the improved telescopes of modern times, we ascertain that upward of several hundred millions of stars exist, that are invisible to the naked eye—the nearest of which is millions of millions of miles from the Earth; and as we have every reason to suppose that every one of this inconceivable number of worlds is peopled like our own, a consideration of this fact—and that we are undoubtedly as superior to these beings as we are to the rest of mankind—is calculated to fill the mind of the American with a due sense of his own importance in the scale of animated creation.
