72 G PROGRESB OF ASTRONOMY FOR 1891 AND 1892. 



4 meters (13 feet) and a room for the refractor with a dome 4J meters 

 (15 feet) in diameter. The instrumental equipment is very meager, 

 consisting- chiefly of a 4i-inch telescope, a transit, clock, chronometer, 

 chronograph, electrical and other subsidiary apparatus. The director 

 reports but little astronomical work accomplished. 



Cambridge (England): Ball. — Prof. Adams has been succeeded as 

 director by Sir Robert Ball. Considerable progress has been made 

 upon the zone work. Tlie 25-inch Newal! refractor has been used for 

 physical observations of i)lanets and photography of stellar spectra. 

 A spectroscope has been provided from " the Bruce fund." 



Cape of Good Hope: Gill. — Transit circle observations of the sun, 

 Mercury, Venus, and of stars for a new ten-year catalogue, stars oc- 

 culted by the moon, stars erajdoyed for latitude determinations, etc.; 

 with the heliometer, measures for stellar parallax and measures of Jupi- 

 ter's satellites have been made, and with the zenith telescope, after 

 its renovation, observations for an investigation of the constant of 

 aberration. The photographic work has consisted of miscellaneous 

 photographs of stars and planets, in addition to regular astrophoto- 

 graphic charting. 



The catalogue of the Southern Photographic Burchmusterting has 

 been made ready for the press. 



Carleton : ^Sce Goodsell. 



Chamberlin: Roive — The building has been com]ileted at a cost of 

 $25,000. 



Chicago — See Kenwood, Yerkes. 



Columbia (Missouri) : Updegraff— The observatory of the University 

 of Missouri (lat. + 38° 56' 50" ; long, l^^ T" G^4 west of Washington) 

 was first built in 1853, and then consisted of a small wooden structure 

 in which were mounted a 4-iuch Fitz equatorial, a 2ii6-inch transit by 

 Brunner, a sidereal clock, and other smaller instruments. It was used 

 for the i)urpose of instructiug students in astronomy, and few changes 

 or additions were made till 1880, when a 7^-inch equatorial by Merz & 

 INIahler was bought. The building was then removed to another part 

 of the college grounds and enlarged by the erection of a l)rick tower, 

 with a dome, for the newly acquired telescope. Soon after a sidereal 

 clock, a chronograph, and spectroscope, all by Fauth & Co., were pur- 

 chased. A 2-inch altazimuth, by Blunt, of jSiCW York, had been bought 

 some years before. The director at tliat time was Prof. Joseph Fi(;k- 

 lin, who died in September, 1880. 



Prof. Milton Updegraft" was appointed director in July, 1890, and 

 while much of his time is taken up in teaching classes in astronomy 

 and mathematics, he has done excellent work in the observation of 

 planets and comets, besides a redetermination of latitude and longi- 

 tude, the latter by telegraphic connection with the observatory of 

 Washington University, St. Louis. The obseivatory building has been 

 enlarged by the addition of an ottice room and a library.
