This is the second number of the series of "BOOKS ON THE SCIENCES, FOR YOUTH," undertaken by the Author.

It is true that several small books on the same science, “designed for beginners," are already before the public. But the Author of this, has seen none which he thought brought the subjects down to the capacity of youth, and explained them in the plainest possible

manner.

This volume begins with the Moon, which is obviously the most familiar and interesting celestial object, which youth can examine without astronomical apparatus.

It is also that part of astronomy which is most easily explained to the comprehension of the young mind, and therefore the best calculated to fix his attention to the subject.

After the Moon, the Earth is treated of as a planet, and her relations to astronomy as a celestial orb, when viewed from the moon and other planets, are described and illustrated.

After these, follow descriptions of the other planets in their order, as is done in other books.

If the author has not made the different subjects connected with this science more easily comprehended, and therefore better adapted to the capacities of youth than others, he has failed in one of the principal objects of this little volume; but of this the public must now judge.

Hartford, Conn. Feb. 1838.
