j)liotomet)ic observations iiKulc bv Mr. l\iil<liust lias been publislied 

 in tbe Harxanl Observatory Annals, vol. IS, No. 3. Approximate 

 position, latitude, +40'^ 41' 2"; longitude, 4'' 55'" 5()M west of Green- 

 wich. 



JirusseU, — A catalogue of 10,792 stars upon which work was begun 

 more than thirty years ago by Quetelet has at length been finished. 

 M. Stuyvaert is engaged ui)on the formation of a catalogue of compari- 

 son-stars, which have appeared in volumes 107 and 108 of the Astrono- 

 niische Nachrichten. Double stars, comets, and occultatious by the 

 moon have been observed with the.e(piatorialsof 38 and 15 centimeters, 

 and numerous physical observations of the moon and planets have also 

 been made. M. I'abbe Spec is especially occupied with a study of solar 

 spots and protuberances, and M. Fievez with the study of the solar 

 spectrum. Tlie new observatory at Uccle is practically finished. 



Camhriflf/e {England). — Considerable progress has been made with the 

 zone +250 to +30O. 



Camden {New Jersey). — Mr. E. E. Keed has erected a small private 

 observatory, with 6 inch equatorial. 



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

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

 the Cape ten-year catalogue for 1890, comet comparison stars, stars 

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

 determinations 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 circumpolars and latitude stars, the 

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

 comets. The i)hotograi)hic "Durchmusterung" is proceeding rapi<lly, 

 the instrument being kept at work by two observers from evening 

 twilight till dawn. The reduction of the plates from declination — 9(P 

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

 measurement to — 57° have been sent to him. It is expected that the 

 photographs will be completed by the end of 1889; their reduction 

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

 ceived from Kepsold, and mounted in the latter part of 1887; it is 

 pronounced by Dr. Gill the most powerful and convenient instrument 

 for refined micrometric research at present in existence. A complete 

 working programme has been prepared, including the determination of 

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

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

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

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

 served from 1835 to 1880, forming vol. 1, part 4 of the Anuals, and a 

 discussion of the variations of the instrumental adjustments of the 

 transit circle have been published. 



Carleton College. — An illustrated description of the building and in- 

 struments is given in the Sidereal Messenger for October, 1888. The
