A recent traveller in Abyssinia has discovered a tribe of Jews in that country. They are called Falasha. Their chief priest, the Rabbi Yshaq (Isaac), told the traveller that they first entered the country in the time of King Solomon, and that they have uninterrupted traditions, though no written history, of the principal events that have occurred to them since that remote period. Their religious rites and belief are the same in substance as those of the European Jews, but some of their doctrines are quasi-Christian. Indeed, they say that it was from them that the early Christians took some of their customs and points of belief. They have a tradition of St. Paul having been in communication with them, and they hold him in great respect. They never, it seems, quitted their own country, and were shocked at the idea of going to sea in ships. "How at sea," they asked, "can the Sabbath be respected?" They know little or nothing of Europe; but on being told that vast numbers of their fellow believers resided in it, expressed pleasure and sent them their fraternal good wishes.
A French gentleman, M. Mariette, has made some important discoveries in the ruins of Memphis, and the Academy of Moral and Political Sciences has called on the government to afford him the pecuniary means of continuing his researches. The National Assembly, on the demand of the government, voted 20,000 francs ($6,000) for this purpose. M. Mariette has brought to light a number of basso-relievos, some statues, and about five hundred bronze figures. But his greatest discovery is the Temple of Serapis, and it is to free it from the soil which has covered it for ages that the money has been specially granted. One of the most magnificent temples which this deity possessed, or, indeed, which existed in the world, was that at Memphis; and it enjoys the peculiarity of containing ornaments in the Grecian as well as the Egyptian style, it having been in its highest glory about the time at which some of the Grecian idolatry was introduced into the ancient worship of Egypt. It is known to contain twelve statues of deities mounted on symbolical animals, all of more gigantic size than any hitherto found, also two splendid figures of the Sphinx, and two enormous lions in the Egyptian style: but the Sanctuary of the Temple, which has not yet been explored, will, it is expected, bring to light things far more curious, and of the highest historical importance. Altogether, it is expected that M. Mariette's excavations at Memphis will rival those of Dr. Layard at Nineveh.
It will be remembered that an island, about 120 feet high and 2,000 feet in circumference, suddenly sprang up in 1831 between Sicily and La Pantellaria. It disappeared about a month after, and at a later period even the sounding lead could give no indications of its existence; but vessels passing over the place it had formerly occupied would sometimes feel a sort of shock, which showed that it was of volcanic origin. In March last, however, the French vessel Eole, which was taking soundings in the vicinity, discovered some traces of its existence; and we now learn from Naples that in the course of the last month Her Majesty's ship Scourge, Captain Kerr, verified the truth of the preceding observation, and further discovered that the island, which had been christened "Isola Giulia," was only nine feet under water. Captain Kerr had a pole with a streamer and an inscription set up on the spot.
The experiments for the production of Photographs in Natural Colors appears to have been carried on simultaneously by Mr. Hill in this country and by several persons abroad. The Athenæum says that in some experiments made by Sir John Herschel a colored impression of the prismatic spectrum was obtained on paper stained with a vegetable juice. Mr. Robert Hunt published some accounts of the indications of color in their natural order obtained on sensitive photographic surfaces. These were, however, exceedingly faint, and M. Biot and others regarded the prospect of producing photographs in colors visionary,—not likely, from the dissimilar action of the solar rays, ever to become a reality. M. Becquerel has a process by which, on plates of metal, many of the more intense colors have been produced; but it appears to have been reserved for the nephew of the earliest student in photography, Niepce, to produce on the same plate, by one impression of the solar rays, all the colors of the chromatic scale. Of this process, called by the discoverer, Heliochromy—sun-coloring—we have had the opportunity of seeing specimens. They are three copies of colored engravings,—a female dancer and two male figures in fancy costumes; and every color of the original pictures is faithfully impressed on the prepared silver tablet. The preparation of the plates remains a secret with the inventor, but the plate when prepared presents a dark brown, nearly a black surface, and the image is eaten out in colors. We have endeavored by close examination to ascertain something of the laws producing this remarkable effect; but it is not easy at present to perceive the relations between the colorific action of light and the associated chemical influence. The female figure has a red silk dress, with purple trimming and white lace. The flesh tints, the red, the purple, and the white are well preserved in the copy. One of the male figures s remarkable for the delicacy of its delineation:—here, blue, red, white and pink are perfectly impressed. The third picture is injured in some parts:-but it is, from the number of colors which contains, the most remarkable of all. Red, blue, yellow, green, and white are distinctly marked,—and the intensity of the yellow is very striking. Such are the facts as they have been examined by the Athenæum, and these results superior to those which were given to the world when photography was first announced.
