Appendix, the ardor and affiduity with which this learned man has been searching after the hidden treasures of Grecian literature, in the library of St. Mark, these three or four years past. Here we have the first fruits of his labours, which Thew that he is as ready to communicate as he is ardent to acquire. The firft volume of this collection contains a work of EUDOCIA, Empress of Constantinople, in the eleventh century, now published, for the first time, entitled, 'Iwna, or Violarium, and containing, in an alphabetical order, an account of all the Gods, Goddesses, Heroes, Heroines, Philosophers, Artists, &c. As this work is partly drawn from the same sources from whence Suidas derived his materials, it will no doubt contribute to the emendation of that author; and as it contains several things either new, or, at least, hitherto too little known, it will certainly excite the curiosity of the philologists. It contains 442 pages, and is published without either a tranflation or notes. The second volume is miscellaneous. It consists, among others, of the following pieces : An accurate Description of the 'Podavia, or Anthology of Macarius Chrysocephalus, from the library of St. Mark, in which we find sentences and fragments of Synesius, D. Chryfoftom, Plutarch, Aristides, Herodian, the 'Orator Æfchines, Lucian, Demofthenes, Libanius, and Choricius. An Oration of Procopius of Gaza, from the library of St. Mark.-A Notice of Extracts that are found in Macarius, from Xenophon, Stohæus, Josephus, Eusebius, Nicephorus, Chummus, Germanus, Conit.

ART. IX. Affronomie

. i. e. A Treatise of Afronomy. Bi M. DE LA LANDE, Member of the Royal Academy of Sciences at Paris. Vol. IV. "Paris." 1731.

HE three preceding volumes of this work were published

about ten years ago, and it has been generally esteemed one of the most complete and learned syften s of aftronomy that háth appeared. The volume before us contains an arnple Treatise on the Ebb and Flow of the Sea- A Memoir concerning the Origin of the Conlellations and the lilustration of Mythology, by the Means of Astronomy. By M. Dupuis, Professor in the Universicy of l'aris. And Supplements to the preceding Volumes by M. DE DA LANDE. There Additions to this valuable Work deserve more than a simple enumeration.

The Tides have been long an object of furprise and inveftigation; and M. DE LA LANDE begins his Treatise with a 'bif. tory of the opinions of the Ancient Philofophers concerning this phenomenon. We do not think the passage of Quintus Curtius, relative to the astonishment which filled the foldiers of Alexander, in their paslage to India, when they saw the fea overflowing the coafts, and afterwards leaving their vefleis in the mud,-a sufficient reason for affirming that the people of Greece were ignorant of the phenomenon of the tides. The paffage, which he himself quotes from the Timeus of Plato, may be ale lcged as a proof of the contrary. In that paffage an attenipt is made to explain this phenomenon by the impreffion which the waters of the Atlantic receive from the rivers that fall into the ocean from the Celtic mountains, and the re-action that is the consequence of this impression. However unsatisfactory this explication may be, it thews that the phenomenon of the tides was known in Greece, and was moreover an object of investigation and research. The notion of the Stoics' on this subject, is recorded by Solinus and Apollonius, is too childish and absurd to de.. ferve mention. Others, among the ancients, confidered the tides as ebullitions, occafioned by subterraneous fires, or as effects of winds and exhalations, or as the confequence of a rarefaction produced by the teams of the moon, or as proceeding from the interruption of the feas by the continents ; in fhort, the hypotheses were various on this head, and they were all in- !! fufficient to account for the appearances. Neverthelefs, as ourl. Author obferves, several of the ancients, and, among others, Pliny, Ptolemy, and Macrobius, were acquainted with the influit, ence of the sun and moon upon the tides ; and Pliny fays ex- 1; pressly, that the cause of the ebb and flow is in the fun, which 1: attracts the waters of the ocean; and adds, that the waters rile in proportion to the proximity of the moon to the earth, flm.

From the ancients our Author proeeeds to the moderns who preceded Sir Isaac Newton in this investigation. He mentions, and confures, in a few words, the hypotheses of Galileo and Des Cartes, and fixes his attention on lunar attraction, as the only explication that accounts for the phenomenon in question. The great English philosopher now mentioned, proved that the ebb and flow was the eff. Et of universal attraction, and Halley was. the first who drew from this principle an ample theory of the tides.

But as the problem of the tides was susceptible of a profound analytis, and the researches of Sir Isaac Newton admitted of, and even required a farther developement, the Royal Academy of Sciences at Paris proposed this problem as the subject of a prize, for which the three greatest geometricians in Europe contended. These were Meffis. Euler, D. Bernoulli, and Colin M Laurin, who were all crowned and divided the prize. Aster giving an analysis of their differtations, our Author takes notice of the new light which M. d'Alembert calt upon this subject by his excellent reflections on the ebb and low of the fea, in his Memoir con. cerning the general cause of the Winds, which was crowned by the Academy of Berlin in the year 1746; and in which that celebrated philofopher considers the attractive influence of the moon and of the sun on the mass of the air, and exposes Bernoulli's mistake in fuppofing, in the equation he gave for the elevation of the waters, the earth composed of layers of different denfitics.

M. DE LA LANDE supposes, with Newton and D. Bernoulli, that the sea affumes an elliptical figure, answers the objections that the Cartesians have made to this figure, estimates the elevation of the tides under the equator, on the supposition that the earth is a homogeneous fpheroid, explains the reasons of the high tides at St, Malo, and considers largely the principal phenomena of the ebb and fow of the ocean. After having moreover pointed out the effect of the perigee of the moon, her forces in the different points of her orbit, M. Bouger's rule for finding the tides, relatively to the distances of the moon, the effects of the distances of the fun, the differences of the solstices at different beights and hours, our Author examines this question, Whether the sides of the equinoxes are always the higheft? and proves, that the affirmative takes place only in certain cases. He afterwards treats of the tides in narrow seas, and particularly in the Mediterranean, of the extraordinary motion of the sea, of the tides in the rivers, &c. This is followed by an account of the observations that have been made relative to the tides in different parts of the globe, and by tables of the hours and heights of the cides in these parts.

The aftronomical reader must consult the Treatise itself, to form a just notion of its contents, which are highly instructive,
