148 RECORD OF SCIENCE FOR 1886. 



scopic observations and drawings of the i)lanets liave been continued 

 as heretofore. 



EiUshorougli, Ohio. — Private observatory of Uenry A. Pavey. Ap- 

 proximate position: Latitude, +39'^ 12'; longitude, 5^' 3t'" west of 

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

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

 ries. Physical observations of the sun aud Jupiter have been made, 

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

 served in accordance with the plan proposed by Professor Pickering. 



Kalocsa Observatory (188G).— Dr. G. Braun has published a report of 

 the observatory founded by Cardinal Haynald, archbishop of Kalocsa. 

 The iustruments 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 

 -|-4G'3 3P 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 been 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- 

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

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

 6 inch refractor by SteinheU, lately remounted by Pecker «& Co., of 

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

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

 the telescope. has an aperture 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 Ilohwii, of Amsterdam — 

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

 etc. 



The personnel consists, at present, of the director, one regular assist- 

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

 begun with the m Pridian circle a series of observation of all stars down 

 to the eighth magnitude between 0° and 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 antl pub- 

 lished in parts 1 and 2 of the " Verofientlichungen " of the observatory. 

 The assistant. Dr. von Rebeur-Pasch'witz, 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 finished. 

 The filar micrometer has been carefully investigated. Herr von liebenr 

 has also completed an exhaustive discussion <^f comet 1882 I (Wells). 

 The second assistant, Herr L. Stutz, makes regular observations with
