Abstract

WE learn from Oran that the French officers of the Staff in Algeria perceived for the first time on September 9 the electric light from the Spanish station of Tetica, at a distance of 272 kilometres. Commandant Perrier, director of the Algerian Survey, was enabled to measure one angle of the triangle, and the other having been measured from the Algerian station on the mountains, the operation may be considered as having been quite completed, and the junction of the Algerian network with the European triangulation an accomplished fact.
