The Publisher submits to the candid acceptance of his fellow-citizens, this correct American Edition ; for which he solicits, and flatters himself he shall obtain, their liberal patronage.

1

No cost or pains have been spared to render it worthy of this patronage. In the text, a number of typographical errors, and grammatical inaccuracies, have been corrected; and a variety of notes, explanatory or corrective of the text, which the numerous discoveries since our author's time had rendered necessary, have been occasionally subjoined.

Besides, to this edition alone there is prefixed a copious explanation of all the principal terms in astronomy, chronology, and astronomical geography, occurring in the

work, arranged in alphabetical order; with such remarks and examples interspersed, as were judged necessary for illustration: together with Tables of the periodical times, distances, magnitudes, and other elements, of all the planets, both primary and secondary, in the solar system ; according to the latest observations.

This, it is presumed, cannot fail to be considered as a valuable appendage to the work—especially by the young student of astronomy: as the glossary will tend greatly to 'facilitate his progress, and the tables will present him with a comprehensive view of the whole science—the result of the observations and researches both of past and present times.
