ASTRONOMY. 141 



cal instruments has recently been added. It consists of Hough's baro- 

 graph and thermograph and an anemograph. 



The observatory is under the direction of Prof. M. W. Harrington, 

 who is assisted by Mr. J. M. Schaeberle and a meteorological observer. 

 Professor Harrington has devoted considerable time during the past 

 few years to photometric observations, especially of the asteroids. Mr. 

 Schaeberle has made observations with the meridian circle. 



The observatory plant is valued at about $40,000, and the annual ex- 

 penditures amount to about $3,000. It should be mentioned that the 

 American Meteorological Journal is edited here by Professor Harring- 

 ton. 



Armagh (1886). —Under the direction of Dr. Dreyer the Armagh cat- 

 alogue of 3,300 stars has been published. 



Bamberg (1886). — This observatory, founded by the will of the late 

 Dr. Eemeis, of Bamberg, who died in 1882, will be provided with a 7- 

 inch heliometer, the largest instrument of its kind made. Dr. Hartwig 

 proposes to take up the systematic investigation of stellar ijarallax, and 

 the investigation of the physical libration of the moon. 



Berlin (1885). — With the meridian circle, Dr. Kiistner has observed a 

 series of comparison stars for planets and comets, stars which have been 

 occulted by the moon, stars for heliometer investigations, etc. There 

 have been made in all 2,096 observations of right ascension and 1,936 of 

 declination ; the reductions are up to date. A new observing list, con- 

 taining the Pulkowa "Zusatzsterne" and Argelander's proper motion 

 stars — about 1,000 objects in all — was started in 1886. The transit has 

 been used for observations of circumpolars, and also for continuing the 

 observations upon seven selected pairs of stars, which are to furnish 

 data for determining the constant of aberration. With the 9-inch re- 

 fractor Dr. Knorre has observed a large number of comets and planets, 

 and with the aid of his " declinograph " he has determined the positions 

 of about a thousand stars, some as faint as the thirteenth magnitude. 

 Dr. Battermann observed occultations with the 4.6-inch refractor. The 

 investigations upon the movements of piers have given interesting re- 

 sults, and the clock which has been for four years in a hermetically 

 sealed case, continues to perform most satisfactorily. 



Bonn (1885). — The meridian circle was devoted, mainly, to continu- 

 ing the Gesellschaft zone observations. Volume viii, the Southern 

 Durchmusterung, was published during 1886, and the printing of the 

 twenty-four charts which are to accompany this work has been begun. 

 The reduction of the zone work is not quite finished. The director, 

 Dr. Schonfeld, has been assisted in observing by Drs. Scheiuer, Deich- 

 miiller, and W. Luther. Dr. Scheiuer was absent a considerable por- 

 tion of the year, serving a term of military dutj'. 



Breslau (1885). — The observatory, uuder the charge of the veteran 

 Dr. Galle, is engaged in meteorological and magnetic work. Assistant, 

 Dr. Lachmann.
