Abstract
“AS an example of needless duplication, fifty observations agreed to observe the planet Eros during its opposition in 1900, but so far as known, only two or three have made the reductions needed to render their observations of any value.”So wrote Prof. E. C. Pickering in April, in his “Plan for the Endowment of Astronomical Research ”; and he is not alone in asking, directly or indirectly, when we may expect to have the result of all the wolk done at the opposition of 1900–1. The tenth Eros circular, dated June 1, appears at the right moment as a provisional reply. It gives the results of equatorial observations at twelve observatories, all compared with the ephemeris; and two splendid series of photographic observations made fct Bordeaux and Paris, completely reduced so as to* show not only the comparison of the planet's place with the ephemeris, but a series of places for individual stars such as has never been given before. If these two-observatories had done nothing else in the two years elapsed since the plates were taken, they might be congratulated on a fine piece of work. Other results will doubtless follow now that these are in print to act as an incentive, and we need have no fears for the ultimate result.
