166 RECOliD OF SCIENCE POR 1887 AND 1888. 



RE POUTS OF OBSEEVATOlilES. 



In collecting tlie following- notes upon observatories the latest avail- 

 able information bas been ntilized, but it has been found impossible to 

 b;ing- the report in each case down to the end of 1888. The Viertel- 

 jahrsschrift, for instance, from which the data for many European ob 

 servatories are drawn, contains reports no later than 1887, and compar 

 atively few observatories publish independent annual reports. The 

 writer's thanks are due to Sr. Felipe Valle for notes on the observatories 

 ot Mexico. 



Ann Arbor. — Prof. W. W. Campbell has been appointed assistant to 

 fill the vacancy made by the removal of Mr. Schaeberle to the Lick Ob- 

 servatory. 



Armagh. — Dr. Dreyer has devoted a large part of his time to the i^re- 

 paration and passing through the press of a new general catalogue of 

 nebuhe. 



Bamhen/. — An interesting description of the new observatory is given 

 in the Vierteljahrsschrift for 1887, p. 333, by the director. Dr. E. Hart- 

 wig. The sum of 115,000 was available for buildings, $17,500 for in- 

 struments, the interest on $20,000 for salaries, and on $12,500 for main- 

 tenance, with a reserve fund of about $20,000. The observatoi'y con- 

 sists of two buildings, the observingrooms being in one and the offices 

 and dwelling in%ie other. In the first there are two towers surmounted 

 by domes and connecting them is the transit room. A long covered 

 way from the dwelling gives easy access to the instruments. The latter 

 are a 7-inch Repsold-Mera heliometer similar to the one at the Cape, a 

 10 inch refractor, a Eepsold-Merz transit with zenith-telescope attach- 

 ment, G-inch Merz comet-seeker, clocks, chronometers, and subsidiary 

 ai)paratus. 



Basel (1886). — The astronomical observatory and nieteorological sta- 

 tion are under the direction of Dr. E. llagenbach-Bischolf, assisted by 

 Dr. Riggenbach. The instruments are used principally for the deter- 

 mination of time and for the instruction of students. 



Bcloit. — The equipment of the Smith Observatory, Beloit College, 

 whi(;h was built in 1883 and ready for work in 1884,- consists of an 

 ecpintorial refractor of Di inches aperture, objective by Clark, mount- 

 ing by Warner and Swasey; a combined transit and zenith telescope 

 of 2.0 inches aperture, jnade by Prof. C. S. Lyman {see Amer. Jour. Sc, 

 XXX, p. 52); clocks, sidereal chronometer, chronograph and minor ap- 

 paratus, and meteorological and photographic outfit. Directors: John 

 Tatlock, jr., 1881-85; C. A. Bacon, 1885. A local time service is main- 

 tained, and meteorological observations are published daily. 



Berkeley, California. — The "Students'" observatory of the University 

 of California, established in 1887, is designed to furnish to undergrad- 

 uates instrnction in geodesy and the more ])ractical parts of astronomy 

 generally; as rating clocks and chronometers, determining geographical
