comets, &c. The ax>proximate position of the observatory is, latitude 

 +390 21' ', longitude b^ C'" 52« west of Greenwich. 



Dresden (1884) (private observatory of Baron Engelhardt). — two hun- 

 dred and forty- two observations of the positions of comets, planets, and 

 nebulae (198) have been made with the 12-inch equatorial, besides minor 

 observations. 



Bun-Echt Observatory (1885). — Lord Crawford has published Vol. in, 

 containing Division 11, of the account of the Mauritius expedition to 

 observe the transit of Venus, 1884. The Dun-Echt circulars have 

 proved themselves invaluable during the year. 



Dunsinlc. — The South equatorial has been employed as usual in obser- 

 vations on stellar parallax. The list of southern stars mentioned in former 

 reports, observed with the meridian circle, has been supplemented by a 

 list of proper motion stars. 



Dilsseldorf (1884). — Professor Luther discovered planet 241, Ger- 

 mania, during the year on his Berlin chart for hours. Since 1847, 

 150 planets have been observed 1,233 times at Dusseldorflf with the 

 C-inch telescope. 



Ealing (Mr. Common's observatory). — Experiments in astronomical 

 photography. Comet 1885 III, independently discovered on Septem- 

 ber 4. 



EdivJburgh. — The printing of the Edinburgh Star Catalogue and Ephem- 

 eris for 1830 to 1890 has been resumed, and it is now completed tQ 

 17^ right ascension. 



Fran]{fort-on-the-31ain (1884) (private observatory of Herr Eppstein). — 

 The star gauges were continued on sixty-two nights, in 682 places, 

 2,714 fields, containing 25,875 stars. 



Sun-spots are also regularly observed here. 



Geneva (1884). — The large equatorial has been provided with a spec- 

 troscope. Besides the regular observations relating to meteorology 

 and to chronometers, observations of comets and of the satellites of 

 Saturn have been made. 



Glasgoip. — Astronomical observations during 1885 have been neces- 

 sarily confined to observations of a select list of stars with the transit 

 cir(;le. The meteorological department has finally been put upon a sat- 

 isfactory footing. 



Goiha (1884).— The computations of the zone 20° to 25° of the A. G. 

 have been prosecuted. The meridian circle is used to observe moon 

 culminating stars and others of Mayer's Catalogue, the equatorial for 

 planet and comet observations. 



Greenwich Olservatmy. — The last report of the astronomer royal is 

 for the year ending May 20, 1885, and is one of the most interesting that 

 has appeared for several years. Transit circle: A reversion prism has 

 been us^d in all observations ; a comparison of theresultsfrom the reversed
