148 RECORD OF SCIENCE FOR 1886. 



scopic observations aud drawings of the i)laiiets have been continued 

 as heretofore. 



Billshoroiigh, Ohio. — Private observatory of ITenry A. Pavey. Ap- 

 proxiniate position: Latitude, -f-SO^ 12'; longitude, 5'' 31"' west of 

 Greenwicli. The instruments are a 4-inch equatorial by Benjamin 

 Pike's Sons, with mean-time clock and chronometer, and other accesso- 

 ries. Physical observ^ations of the suii aud Jupiter have been made, 

 aud observations of the zodiacal light. Variable stars have been ob- 

 served in accordance witli the plan proposed by Professor Pickering. 



Kalocsa Observatory (188G). — Dr. C Braun has published a rei)ort of 

 the observatory founded by Cardinal Haynald, archbisho]) of Kalocsa. 

 The instruments are a refractor, by Merz, of 7 inches ; another of 4 

 inches; a transit, by Cooke, of 2.3 inches: altazimuth, clocks, spectro- 

 scopes, photometers, etc. The latitude from geodetic observations is 

 +4GO 31' 41".92 ; astronomical methods give it 0".07 greater. The lon- 

 gitude is 1^ 15°" 54^343 east of Greenwich. A valuable series of sun- 

 spot observations has been made and discussed. 



Karlsruhe (1886). — The observatory at Karlsruhe (Baden) is still in 

 a small, temporary, wooden building, the instruments having beeu re- 

 moved in 1881 from Mannheim to the present quarters in Karlsruhe, 

 where the observatory forms a part of the '^ Techniche Hochschule." 

 Unfortunately the financial condition of the Grand Duchy of Baden has 

 thus far precluded the establishment of a thoroughly equipped observa- 

 tOTy, which has been in contemplation. The temporary building has 

 two small meridian rooms, and a dome. The instruments are: (1) a 

 Cinch refractor by Steinheil, lately remounted by Pecker & Co., of 

 Wetzlar; (2) an old repeating circle by Keichenbach some years ago 

 changed into a meridian circle by Hildebrandt & Schramm, of Preiberg; 

 the telescope has an ai)LTturo of 84 millimeters (3.3 inches); the divided 

 circle is 3 feet in diameter ; (3) a large portable transit instrument by 

 Bamberg, of Berlin ; (4) two fine clocks by Hohwii, of Amsterdam — 

 one with break-circuit attachment ; (5) chronographs, chronometers, 

 etc. 



The personnel consists, at i^resent, of the director, one regular assist- 

 ant, and a temporary assistant. The director, Dr. W. Valentiner, has 

 begun with the meridian circle a series of observation of all stars down 

 to the eighth magnitude between 0° aud 20° of south declination , each 

 star will be observed six times. So far about nine thousand observa- 

 tions have been made, and mosc of these have been reduced and pub- 

 lished in parts 1 and 2 of the '' Verottentlic'nungen " of tho observatory. 

 The assistant. Dr. von Eebeur-Pascliwitz. uses the refractor for observa- 

 tions of comets, occultations, etc.; his principal work is the micromet- 

 rical measurement of star-clusters ; two groups will soon be tiiiished. 

 The lilar micrometer has been carefully investigated. Herr von Pcbeur 

 has also completed an exhaustive discussion of comet 1882 1 (Wells). 

 The second assistant, Herr L, Statz, makes regular observations witU
