Identical results would, as it happened, have been obtained with half the amount of labour; but possibly had the shortened computations alone been performed, the results, though equally accurate, would not have inspired equal confidence, and therefore it is perhaps as well that the full work has been done. P. H. C. Mesubes Micbometeiques D'etoiles Doubles Faites A St. PiTEBSBOUBG ET 1 DOMKINO IN 1895. Prof. S. GrlASEHAPP. "We are always glad to welcome the double star measures of Prof. S. Glasenapp, who spends his summer vacation at Domkino, where he has a delightful climate. His 7-inch refractor always forms part of his luggage, and as he measured 265 stars we may be sure he succeeded in imbibing as much as possible of the pure night air of Domkino, and was well braced up for his University duties at St. Petersburg. The measures are of neglected wide pairs and a fair proportion of close doubles. This is the fourth series of measures made by Prof. Glasenapp. This comet was discovered on 1895, Nov. 21, and 78 observations were obtained, ranging over about a month. The comet was faint and ill-defined, and a difficult object to observe accurately However, the above elements satisfy the observations well, and the orbit does not appear to differ sensibly from a parabola. Thesupposition of identity with the comet of 1652, which was made at the time in consequence of the resemblance of the elements, would therefore appear to be untenable. A. C. D. C.
