Asclepiodorus, the Athenian sculptor, as well as painter, was as the latter, celebrated for the beauties of a correct style, and the truth of his proportions. Appelles allowed himself to be, in these respects, as much his inferior to this artist as he was to Amphion on the good ordering and disposition of his figures. About this period appeared Nichomachus, Nichophanes, Pyreicas and others. Nichias, an Athenian, 322 B. C., was in great repute for the great variety and noble choice of his subjects, for the mode of distributing his lights and shadows, and for great skill in the representation of animals. In Rome, 300 B. C., Fabius, a noble Roman, painted the Temple of Health, and gloried so much in the art, that he assumed the name of Pictor. Without a further enumeration of masters, for a long period after the reigns of Vespasian and his son Titus, painting, as well as sculpture, continued to flourish in Italy. Even under their successors Domitian, Nerva and Trojan, they met with as much encouragement as they did in the most palmy days of Greece, although painting was used in mere ornamental decorations--that is, to a great extent, and artists had sunk, for the most part, to the standard of mere mechanics. Under Adrian, Antonine, Alexander Severns, Constantine, and Valentinian, the art of painting continued to be an object of interest; but at length, in the reign of Phocus, with the fall of the Empire, with the rest of the noble arts and sciences, it was involved in the common heap of ruins. (To be continued.) * * * * * BROMINE. We give the folk wing interesting combination and experiments with bromine, as found in Hill's Treatise:-- "Discovered in 1826, by M. Balard, a young chemist of Montpellier, France. He named it _Muride_, because obtained from the sea; but it acquired its present name from a Greek word, signifying _rank_, or _dead odor_." It exists in nature in very small quantities. It is found in the waters of every sea which has been tested for it: it is also found in many mineral and salt springs. We have not been able to determine to whom belongs the honor of discovering its use as an accelerator in Daguerreotype. Having corresponded with Prof. Morse, (who was certainly one of the first who took portraits by the Daguerreian process,) Dr. Draper, and others, to whom this honor has been awarded, they refuse to claim it. Prof. Silliman, who is supposed to know everything relating to science, writes to me that he does not know this. I am quite inclined to place the wreath on the brow of the inventor of the Magnetic Telegraph.
