The battle of Concon took place Aug. 21, 1891. Nine thousand Congressional troops advancing toward Valparaiso from Quinteros Bay, where they had landed the day previous, were met by Balmaceda's troops on the other side of the river Aconcagua. The Esmeralda and the Magellanes, co-operating from the sea, made fearful havoc among the Balmacedists with their machine guns and shell. After a stubborn fight the Balmacedists were totally defeated, and were pursued by the victorious cavalry, losing 4,000 out of 12,000 in killed, wounded and deserters. All their field pieces were captured, and thus the road was left open for the Congressionalists to advance on Vina del Mar. THE BATTLE OF VINA DEL MAR, CHILE. A general engagement took place on Aug. 23, 1891, between divisions of Balmaceda's and the Congressional troops, with the Esmeralda and the Almirante Cochrane aiding the latter by firing at Fort Callao, endeavoring to silence the field batteries at the back. The Congressional troops failed to capture Vina del Mar, but eventually cut the railway line a few miles out, and crossed over to the back of Valparaiso, which was soon captured.--_The Graphic._ * * * * * THE SUN'S MOTION IN SPACE. By A.M. CLERKE. Science needed two thousand years to disentangle the earth's orbital movement from the revolutions of the other planets, and the incomparably more arduous problem of distinguishing the solar share in the confused multitude of stellar displacements first presented itself as possibly tractable a little more than a century ago. In the lack for it as yet of a definite solution there is, then, no ground for surprise, but much for satisfaction in the large measure of success attending the strenuous attacks of which it has so often been made the object.
