Tyyu.sseh: — A catalogue of 10,792 stars upon Avhioli work was begun 

 more than thirty years ago by (^uetelet has at length been finished, 

 M. IStuyvaert is engaged upon the formation of a catalogue of compari- 

 son stars, wdiicli have aj)j^eared in volumes 107 and lOSof the Astrono- 

 mische Nachricliten. Double stara, comets, and occul tat ions by the 

 moon have been observed witli the equatorialsof 38 and 15 centimeters, 

 and numerous pliysical observations of the moon and planets have also 

 been made. M. I'abbe Spec is especially occui)ied with a study of solar 

 spots and ])rotuberauces, and M. Fievez with the study of the solar 

 spe<;trum. The new observatory at Uccle is practically finished. 



Camhruhje {England). — Considerable progress has been made with the 

 zone +250 to +30°. 



Camden {Neiv Jersey). — Mr. E. E. Reed has erected a small private 

 observatory, with (> inch equatorial. 



Ca2)e of Good Hope — With the transit-circle regular observations 

 liave been continued of the Sun, Mercury, Venus, stars on the list of 

 the Ca[)e ten-year catalogue for 1890, comet comparison stars, stars 

 occulted by the Moon, stars employed in the latitude and longitude 

 determinatiouH of the Geodetic Survey, and stars employed in zones 

 for determining the scale value of the heliometer. The large theodolite 

 has been used for observations of cinmmpolars and latitude stars, the 

 zenith telescope for latitude, and the equatorial for observations -of 

 comets. The photograj)hic "Durchmusterung" is proceeding rapidly, 

 the instrument being kept at work by two observers from evening 

 twilight till dawn. The reduction of the plates from declination — 90<^ 

 to —77^° has been completed by Professor Kapteyn, and plates for 

 measurement to — 57° have been sent to him. It is expec-ted that the 

 photographs will be completed by the end of 1889; their redu(;tion 

 will probably require two years longer. The new helionieter was re- 

 ci'ived from Repsold, and mounted in the latter part of 1887; it is 

 jironounced by Dr. Gill the most powerful and convenient instrument 

 for refined micrometric research at present in existence. A complete 

 Avorking programme has been i)repared, including the determination of 

 the parallax of all the southern stars brighter than magnitude 2.0 and 

 all the stars most remarkable for proper motion. Some i)rogress has 

 been made in the determination of the constants of the instrument. 

 The meridian observations for 1882, 1883, and 1884, occultations ob- 

 served from 1835 to 1880, forming vol. 1, part 4 of the Annals, ami a 

 discussion of the variations of the instrumental adjustments of the 

 transit circle have been ])ublished.
