422 SCIENTIFIC RECORD FOR 1885. 



the examination of some seven hiiudrecl and fifty places in the sky to 

 solve doubts. In December, 1883, the charting of the stars on the maps 

 was again begun and finally completed in March, 1885. The catalogue 

 will contain 133,658 stars between — 2° and — 23°; 692 more are given 

 north of these limits and 479 south. 



Bordeaux. — This observatory, founded in 1871, has just now {Comptes 

 Eendus, 101 : 690, 1885), published its first volume of Annales, con- 

 taining a minute description of the instruments (a meridian circle of 

 0-19™ aperture, two equatorials of 0-22 and 0'39'°, and three clocks), and, 

 also, a determination of the longitude of the observatory. An impor- 

 tant piece of work has been undertaken by the director, M. Eayet, in 

 the re-observation of the 23,000 stars in Argelander's southern zones, 

 between — 15° and — 31° of declination. The latitude is given as 

 + 44° 50' 7"-23. (Science.) 



Boswell Observatory, of Doaue College, Crete, Nebr., is due to the 

 liberality of the late Charles Boswell, of West Hartford, Conn. The 

 observatory possesses a full set of meteorological instruments in addi- 

 tion to its astronomical equipment, and is a signal-service station, co- 

 operating with the United States Signal Service at Washington. A 

 time-ball is dropped daily at noon. 



Brussels. — The transit and mural are used to observe moon culminat- 

 ing stars. A general catalogue of the stars observed at Brussels in the 

 years 1857-'78, reduced to 1865, will be printed during 1885. M. F. 

 Folie, administrating inspector of the University of Liege, has been ap- 

 pointed director. Since the resignation of M. Houzeau, the direction 

 has been in the hands of a committee of three, MM. Stas, Liagre, and 

 Mailly. 



Buchtel College Observatory, Al^ron, Ohio. — Approximate latitude, -f-41° 

 3' ; approximate longitude, b^ 26°^ west of Greenwich. The observatory 

 was erected in the summer of 1885, and the instruments set up about 

 March 1, 1886. The following instruments are in use : 



Transit circle of 3 inches aperture, by Fauth «& Co., of Washington. 

 The circles are 16 inches in diameter, one being coarsely divided on the 

 edge and serving as a finder, the other being divided on silver to five- 

 minute spaces and reading by two micrometer-microscopes to single sec- 

 onds. The telescope is provided with right ascension and declination 

 micrometers. A fine level is attached, so that the instrument can be 

 used as a zenith telescope ; reversing apparatus, plain and diagonal 

 eye-pieces accompany the instrument. 



Sidereal clock, by E. Howard & Co., of Boston. This clock is x>rovided 

 with electrical attachments for oi)erating the chronograph. Chrono- 

 graph, by Fauth & Co. Mean time clock, by Fauth & Co. This clock 

 is provided with Gardner's electrical attachments for operating chrono- 

 graph, dropping timeball, and correcting a system of controlled clocks.
