The engines of the Necochea are expected to develop 13,, and to propel the ship at a speed of 22 knots—nearly 26miles—an hour, and it is lioped that this may be slighily ex-ceeded on trial. An African Observatory. — A remarkable scientific establish-menthas just been completed by M. Colin, which is the onlyobservatory on the east coast of Africa. It is on the island r ^. of Madagascar, and is placed at an altitude of 1,400 meters(about 4,600 ft ), on the summit ol a mountain a few miles fromTananarivo. It is a handsome structure of cut stone, with fourcupolas. The cost was met by contributions from persons andassociations interested in developing Frencli influence in thatcountry. It has also the support of the French Academy ofSciences. Besides astronomical work, M. Colin has organized a regu-lar service for meteorological observations with posts at differ-ent pomls on (he island. The observatory is well supplied with instruments, including amagnelograph, and valuable results are expected, both astro-nomically and in information concerning the climate and meteor-ological conditions of Madagascar and the neighboring seas,heretofore but little known.
