To complete the object of this Dissertation, the author intended to review the Astronomical and Geological evidence for the antiquity of the globe; but the Scriptural and Historical evidence for the _true age of the world_, appeared to him of such paramount importance, and of so overwhelming a nature, that he was compelled to devote his best attention to its development and elucidation. If he has been successful in this attempt, it will be to him a source of no small gratification, and no small reward for his labour; it will also be a powerful inducement to prosecute his intended investigations, having, in this work, only very slightly touched on the Geological question, and not at all on the Astronomical, except in what relates to the cyclical character of the Mundane Times, which may be considered as only the germ of this magnificent subject. Impressed with the idea that the _True Age of the World_ is written in the Heavens by the finger of God, and that the revolutions of the Solar System, if rightly investigated, must lead to its discovery; the author made some astronomical calculations of which at present, he can only communicate the results. Assuming that at the Creation of the world, there was a Grand Heliocentric conjunction of all the Planets, and that at some subsequent period of its history, the same phenomenon would at least be partially visible from its surface, he endeavoured to determine the period or cycle which must elapse before a second conjunction would happen. He found by these calculations, that this cycle was nearly 2401 years, a period which according to the language of Scripture is a _Jubilee of Jubilees_; and, that reckoning from the era of Creation determined in this work, the Second conjunction took place about B. C. 3078, which is within a few years (24) of the date generally assigned to the Hindoo epoch of the Calyougham. He found also, that the Third conjunction took place about B. C. 677, when the remnant of the Ten Tribes was carried away into a long captivity, and the kingdom departed from Israel; and, that the Fourth conjunction took place in A.D. 1725, when on the 17th of March, at Pekin in China, the planets Mercury, Venus, Mars and Jupiter, were all seen in the field of the same telescope at the same instant, by the Jesuit Missionaries Gaubil, Jacques and Kegler. In confirmation of the same epoch of Creation, he also found that the longitude of Sirius, the largest and brightest of all the Stars in the Heavens, and by some supposed to be the central point of attraction to our Sun, was 0° 0′ 0″ on the 21st of March B. C. 5478, according to the most recent determination of the precession of the equinoxes; but the discussion of these curious results and other topics to which he has already alluded, must form the subject of a future volume. _London, Sept. 2nd, 1844._ TABLE OF CONTENTS.
