ASTRONOMY. 133 



DunsinJc Catalogue. — The sixth part of the Diiusiuk observations is 

 devoted to a catalogue of 1,012 stars, between — 2° and — 23° declina- 

 tion, observed witii the meridian circle from 188 L to 1885. The standard 

 stars employed are those of the Berlin Jahrbuch, and the observations 

 are reduced to Auwers' system. The mean right ascensions and decli- 

 nations, with the annual precessions for the epoch 1885.0, the mean 

 epoch, and the number of observations are given. 



Pulkowa. — Volume xii contains a catalogue for 1865.0 of the principal 

 stars, to thefourth magnitude — 381 in number — as far as 15 degrees south 

 declination deduced from observations in the years 1801-1872. Tlie for- 

 mation of a catalogue of these stars for the epoch 1845.0 was the first 

 piece of work completed by this observatory, and the present work is 

 thus enhanced in value by being an almost exact repetition of that un- 

 dertaken twenty years before. 



Auicers'' new reduction of Bradley. — The third volume of Auwers' new 

 reduction of Bradley, which has been five years in going through the 

 press, was finally published in 1888. This volume contains, in addition 

 to the catalogue proper, tables giving the quantities in the reduction to 

 the apparent place that depend upon the star's position, and a compar- 

 ison of Bradley's positions, reduced to 1805, with Berlin and Greenwich 

 observations of about the same date. The catalogue contains 3,208 

 stars, and gives for each star the magnitude, right ascension, and dec- 

 lination for 1775.0, corrections to the Fundamenta of Bessels, number of 

 observations, epoch, precessions for 1755, 1810, and 1805, proper mo- 

 tions, references to Greenwich catalogues, and to double-star cata- 

 logues, where the star was double, and a column of notes. 



An important list of 480 stars to be used as fundamental stars for 

 zone observations between —20° and —80° declination, is published 

 by Dr. Auwers in the Monthly Notices for June, 1887. 



Dr. 0. II. F. Peters lias contributed two valuable papers to the third 

 volume of the Memoirs of the National Academy of Sciences; the first 

 is a critical examination of all data bearing on Flamsteed's twenty-two 

 "missing" stars, for each of which a plausible explanation is found; 

 and the second paper is a list of corrigenda in the catalogues, O. Arg. 

 S., Bonn vi, Weisse (1 and 2), Kiimker, Schjellerup, Baily's Lalande 

 zones, Yaruall, Glasgow, Santiago, and Geneva. 



A very useful index to stars in Airy's six Greenwich catalogues not 

 found in Flamsteed — the work of Miss Lamb — will be found in the 

 fifth volume of publications of the Washburn Observatory. 



Astronomische Geselhchaft Zones. — The following notes condensed 

 from the reports presented at the meeting of the Gesellschaft in August, 

 1887, show the progress of the work at that time: 



Kasan, gO^-ToO.— The second volume of observations has been printed, and the reduc- 

 tions to 1875.0 and tlit! formation of the catalo<;ne have been begun. 

 Dorpat, 750-70".— Partly printed. 

 Chriatiania, 70O-()5°. — Greater part printed.
