732 PROGRESS OF ASTRONOMY FOR 1891 AND 1892; 



motions, observations of planets and asteroids. Zone work +5oto + 

 10°, and +10° to +15°; triangiilation of traix'zium of Orion. Time 

 service and meteorological observations. 



Lick: Hohlen. — A new building has been erected to cover tlie Wil- 

 lard pliotograidiic lens (aperture 5.1) inches, focal length 31 inches), and 

 its mounting by Brashear, presented l)y lion. C. F. Crocker. The dome 

 is 10 feet in diameter, and attached to it is a photographic dark room 

 about 10 by 11 feet. 



A graduate school of astronomy has been established at the Lick 

 Observatory as a part of the graduate system of the University of Cali- 

 fornia, and a special fund established by Mrs. Phebe Hearst is in part 

 available for the expenses of advanced students elected fellows by 

 the regents. 



IJarnard's discovery of a fifth satellite of Jupiter with the 3(J-iiich re- 

 fractor has been referred to elsewhere. 



LifcoE: Folic. — This observatory is attached to the Eoyal Observa- 

 tory at Brussels, and its observations are published in the Brussels 

 volumes. Much excellent theoretial work has been done l)y M. de Ball 

 while awaiting repairs to the meridian circle. 



Liverpool: PUunincr. — Time service, chronometers, meteorological 

 observations. The 8-inch equatorial has been used in the systematic 

 observation of comets. 



Lund: _Fo/At' Engstyom. — Work on zone -f-35o to -f40^, 



McCormick: Stone. — Prof. Stone has published a continuation of 

 the Bonn Durchnuisterung, upon which he has been engaged for a 

 number of years. 



Madras: Smith.— Mr. C. Michie Smith, since the death of Mr. Pog- 

 son, has been chiehy engaged in pushing forward the publication of 

 observations of earlier years. Observations other than those required 

 for the efficient maintenance of the time service have been entirely 

 subordinated to the work of publication. Two volumes of the valuable 

 Madras Meridian Circle Observa.tio)i.s have been issued. 



Melbourne: Elleri/. — Meridian circle work has been continued. 

 The photographic telescope was mounted in January, 1891, and consid- 

 erable progress has been made towards the ])hotographic catalogue. 

 Meteorological and magnetic observations, time service, and chronom- 

 eter rating have been kept up, but the ol)servatory has been seriously 

 crippled by the reduction of its appropriations, necessitating the retire- 

 ment of two assistants, 



Milan: Schiapayclli. — Measurements of double stars; i)reparatious 

 for a catalogue of 1,100 stars, zone +2o to +0° observed from 1800 to 

 1872. Longitude work, time service, and magnetic observations. 



Mississippi University: Fulton. — Under date of July 0", 1891, it 

 was reported (Sid. Mess., I^o. 1)7) that a "twin equatoi'laP' (a 15-inch 

 visual telescope and a 9-inch photographic telescope side by side on the 

 same mounting) was under construction by Grubb.
