The fifth edition.
The text comprises fifty-four lessons on astronomy in catechism form by Asa Smith, the principal of a New York Public School, and "An Explanation of Leap Year", "Equation of Time", "Problems on the Terrestrial Globe", "Problems on the Celestial Globe" and a "Glossary or Explanation of Astronomical Terms". Complete as per the indexes of both the text and of the plates. In addition, the book collates with the 1848 edition in the Princeton University collection.
"It has been the object of the author of this little manual of Astronomical science, to present all the distinguishing principles in physical Astronomy with as few words as possible; but with such ocular demonstrations, by way of diagrams and maps, as shall make the subject easily understood. ... The Diagrams, which are larger and more full than those of any other wok adapted to common schools, are many of them original in their design, and exhibit the positions and phases of the planets in their orbits. The drawings being upon the principle of perspective, exhibit the inclinations of their several axes to the planes of their orbits more correctly than has hitherto been done in any other popular work...." [Quoted from the Preface].
Asa Smith undertook the task of creating and drawing each print on wood. The images were then engraved into the wood for printing. It's not surprising that Smith further writes, in his Preface, that "it has occupied the whole of his spare time for nearly three years; the most laborious part of it being the drawing of the diagrams, &c. on wood, ready for the tool of the engraver, which was done by the Author himself."
