Excerpt from Lessons in Astronomy, Including Uranography a Brief Introductory Course Without Mathematics

It has been thought well also to add brief notes on the legendary mythology of the constellations for the benefit of such pupils as are not likely to become familiar with it in the study of classical literature.

In the preparation of the book great pains have been taken not to sacrifice accuracy and truth to compactness, and no less to bring everything thoroughly down to date. The student will find in their proper places the new results obtained by Schiaparelli with respect to the rotation of Mercury and Venus, the identification of Brooks's comet with the long-lost comet of Lexell, and the latest spectroscopic discoveries of Pickering and Vogel.

The Appendix contains in its first chapter descriptions of the most used astronomical instruments, and where time permits, might profitably be brought into the course. The second chapter of the Appendix is designed only for the use of teachers and the more advanced pupils. Arts. 431-434, however, explaining how the sun's distance may be found in the simplest way, might well be read by all.

My warmest thanks are due to my friend and assistant, Mr. Taylor Reed, who has gone over all the proofs of the book, and has given me many valuable suggestions.
