Astronomers in all parts of the world are now busy in making their preparations for observing the eclipse of the sun in December 21-22, 1870. Although it will not be visible in the United States, it has been suggested that some of the American observers of the last eclipse be sent abroad for the purpose of taking part in the observations of the one in question, and Congress has already appropriated $29,000 to the Coast Survey for the purpose. Great praise was awarded by foreign physicists to the American astronomers for the excellence of their work, and especially for the remarkable photographic pictures that were taken, and at so many points; and it is urged that these same gentlemen, or a selection from them, would be admirably fitted for a, renewed investigation of the kin , since their experience of the first phenomenon would enable them to utilize their time to better advantage during the second. According to a recent writer this eclipse will begin in the North Atlantic Ocean, the line of central and total eclipse, moving in a southeasterly direction, crosses Portugal a little to the south of Lisbon; passing over part of Spain and the Mediterranean Sea, it enters Africa near Oran, and soon afterward attains its extreme southern limit; the shadow of the moon, now moving in a northeasterly direction, leaves Africa, and, crossing the island of Sicily, the south of Turkey, the Black Sea, and the Sea of Azof, disappears; the penumbra of the moon, decreasing rapidly, leaves the earth with the setting sun in Arabia. The sun will be centrally and totally eclipsed at noon in lat. 36° 38′ N., long. 5° 1′ W., a little to the northeast of Gibraltar.
