together with the causes which have produced

them.

The results of Mr. De Luc's long and laborious researches have supplied an additional proof in support of revealed Religion. He has made it appear that the very facts upon which those systems seemed to rest, which assign an indefinite antiquity to our present continents, confirm, on the contrary, in the most satisfactory manner, the chronology of Genesis; and he has successfully traced the striking analogy that subsists between the great Volume of Nature, and the sacred page of Revelation. Thus he has shown, that the revolution which, according to every fact of geology, gave birth to our continents, was effected at the epoch of the Deluge, as it is described in the Mosaic History; and thus likewise he has demonstrated the conformity of geological monuments with the sublime account of that series of operations which took place during the Six Days, or periods of time, recorded by the inspired penman.

Mr.

Mr. De Luc's Geological Letters to Professor Blumenbach, in the British Critic for 1794 and 1795, were intended to point out those connexions: he seldom alludes to them in this work, the subject of which is purely philosophical: but the last of these Letters, on account of its very interesting nature, is, with the author's consent, reprinted here as an Appendix.

The numerous extracts from M. DE SAUSSURE'S Voyages dans les Alpes, adduced by Mr. De Luc in confirmation, either of his system, or of his personal observations, will form, it is presumed, a valuable part of this volume; and they will prove the more acceptable to the English reader, as no translation of the Travels of that eminent geologist into our language, has yet appeared.

WHILE this work was in the press, Dr. HALES's first volume of his New Analysis of Chronology, &c. appeared; and on that publication Mr. De Luc has communicated to the translator the following remark:-" I regret that the Rev. Dr. Hales, "in his work just published, has deemed it necessary "to animadvert upon my Geological system, from some misconceived notions of it; classing me among "the Geologists who have thought-That the antediluvian mountains did not exceed 50 toises in "height;-And that before the Deluge, the earth's "aris was perpendicular to the plane of the ecliptic, "and that its present obliquity took place at the "Deluge, which occasioned an alteration in the "earth's centre of gravity. P. 329. If Dr. Hales "had read my works, or only the VIth of my Let

ters to Professor Blumenbach, in the British “Critic of 1795, (which, as containing a general "view of the agreement of my system with Genesis, "is, in conformity to your wish, to be subjoined to your translation) he would, in the first place, have seen, that I never attempted to fix the height of "the antediluvian mountains, a point wholly indif"ferent to my system. And with respect to changes "in the earth's motions, he would have perceived "that I considered those which I have mentioned, not as a cause of the Deluge, but as consequences "which might have influenced the astronomical ob"servations

"servations subsequent to that event. On this subject, Dr. Hales may see, in a review of Mr. "PHIL. HOWARD's work, The Scriptural History of the Earth, &c. (British Critic, August 1797, p. 108,) that these small changes are adduced as accounting for the remarkable circumstance of the "antediluvian year consisting only of 360 days. "This circumstance served as the foundation of the "ancient astronomical formula, transmitted by "Noah to the Asiatic nations; formulæ which, "however accurate with regard to the antediluvian "state of the earth, had subsequently required cor"rections, on account of a greater number of days "in the year, i. e. of revolutions of the earth on its axis, while describing the same orbit."
