Excerpt from An Introduction to Astronomy: Designed as a Text-Book for the Use of Students in College
The sun, planets, satellites, and comets constitute the solar system, which is so called because the sun is the principal body belonging to it, and controls the movements of all the others.
The fixed stars are the bodies situated at vast distances out side of the solar system, and which, on account of that distance, exhibit little or no change of position with respect to each other.

The revision of Professor Olmstead's Astronomy made in 1861, owing to circumstances which I could not well control, was not so thorough as I desired. The present edition is more in accordance with the idea which was in my mind, but which was then only partially carried out. The changes now introduced are principally of the same nature as those made in the revision of the College Natural Philosophy. Some historical matter is omitted; a few alterations are made in the arrangement Of topics; the subject of nearly every paragraph is pre sented in an italic heading; and, throughout, I have aimed to state principles and describe phenomena with more conciseness, Where I thought I could do it with equal clearness. About one-half of the eu gravings are new. A part of these are for the illustration of points either not illustrated or not discussed before, and a part are substituted for those which were faulty. The true proportions of lines and angles can not, in general, be presented in astronomical diagrams and the pupil must depend mainly on his teacher for the help which he needs in this respect. In a very few cases, where it seemed practicable, a figure is added, simply for the purpose of exhibiting the true size of an angle, and the correct proportion of lines. A few pages at the end of the volume are occupied with tables, which may be found useful.
I am much indebted to Professor Henry H. White, of the Kentucky University, who has very kindly aided me by numerous criticisms and suggestions, of which I have made free use in this revision.

Paperback. Etat : New. Print on Demand. This book marked the first significant publication in the field of astronomy, establishing an entirely new way of understanding the universe. The author argues that the Earth is not the center of the solar system, but rather the Sun, and that the planets revolve around the Sun. This revolutionary concept, known as the heliocentric theory, had been proposed by other scientists before, but it was the author's book that provided the mathematical proof and observational evidence necessary to convince the scientific community. The author also made important contributions to the fields of optics and motion, revolutionizing the study of astronomy and laying the groundwork for future scientific discoveries. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
