estimate of the whole realm of nature as contemplated by the Divine mind, and deeply significant, is the wide interval which, in the Mosaic history of the creation, separates the bringing forth of the beasts by the earth at the command of the Almighty, from the making of man, whereof it is written, “Let us make man in our own image.” Physical science having thus sluggishly advanced through a definite period and number of centuries--having lived through almost two millenniums in little better than an embryo state--made at last the few steps of progress that it has yet taken. By a more rapid march of time, it hastened to suit itself to the riper age of man, and to come forth itself, as it were, mature, although, in many respects, this is even yet very far from being the case. The principal of these advances of physical science is the invention of the compass. For, in the first place, the phenomenon of magnetism presents a remarkable manifestation of the universal life of the world, which eludes all mathematical calculations of magnitude, while the little piece of this wonderful iron balances by its living agency the whole globe itself. And, in the second place, the results to which it has led have been no less important and marvelous. The magnetic index pointed the way to the discovery of the New World, and to a more perfect acquaintance with the figure of the earth, and thus, through an enlarged observation of geographical and astronomical facts, opened out a grander and more extensive view of the whole planetary system. Of the new world in the other hemisphere, a trace unquestionably is to be found in antiquity in the legend of the island of Atlantis. The general description of this island, as equal in extent to both Asia and Africa together, agrees remarkably with the size of America. But the fable contains the additional circumstance, that, having existed in the Western Ocean in very ancient times, it was subsequently swallowed up by the waves. From this circumstance I am led to infer, that the legend did not, as is generally supposed, owe its origin to Phœnician navigators, who, even if it be true that they did succeed in sailing round Africa, most assuredly never ventured so far westward. Like so much besides that is equally great and grand, and, indeed, far grander, the main fact of the legend seems to be derived from an original tradition from the primeval times, when, unquestionably, man was far better acquainted with his whole habitation of this earth than in the days of the infant and imperfect science of Greece, or even of the more advanced and enlightened antiquity. A vague traditionary notion of its existence lived on from generation to generation. But afterward, when even the Phœnician sailors, however far they penetrated into the wide ocean, were unable to give any precise information about, or adduce any proof of, the fact, the hypothesis was advanced, and finally added to the tradition, that the island had been
