The Elements of Astronomy, Or, The World as it Is, and as it Appears
As such a book, The Elements of Astronomy, or the World as it is, and as it appears, is offered by a teacher to the teaching and studying public. Had the writer aimed only to excite an interest in the subject, it would have been shorter and more attractive , but it is intended, likewise, to exercise the student's memory, reason, and imagination.
