Abstract
A METHOD FOR THE DETERMINATION OF THE CONSTANT OF ABERRATION.—Referring to M. Lœwy's plan for the determination of the constant of aberration by measuring the relative positions of stars situated in distant parts of the sky at successive epochs by means of a double mirror placed in front of the object-glass of an equatorial (NATURE, vol. xxxv. p. 282), M. Houzeau points out (Comptes rendus, tome civ. No. 5) that the same idea occurred to him some years ago, and that the fundamental principle of the method, and an enumeration of the advantages attending its application, were published by him in 1871, in a paper entitled “Considérations sur l'Etude des petits Mouvements des Etoiles,” which appeared in tome xxxviii. of the Mémoires de l'Académie de Belgique. It appears, therefore, that M. Lœwy's method cannot, strictly speaking, be considered a new one, though we believe it has never been put into actual practice—a work which we hope to see before long accomplished at the Paris Observatory.
