ASTRONOMY. 413 



Berlin. The zone +20° to +25° is practically finished ; the reductions 

 are now in progress. The equatorial has been used by Dr. Knorre, for 

 observations of comets and asteroids. The Berliner Jahrbuch, with its 

 two series of circulars, has been published as usual. 



Bonn : The zone -f 40° to +50° is still in progress, 1,020 observations 

 of zone stars having been made; the observer, Dr. Deichmuller, took 

 part in the Transit of Venus expedition to Hartford, Conn. The reduc- 

 tions are well up to the observations. The Southern Durchmusterung 

 now counts 357,400 star positions. The final positions of 78,317 stars 

 are now prepared for printing. It should be noted that all the work of 

 the Southern Durchmusterung is done by Dr. Sehonfeld. 



Breslau: The report for 1882 differs from that of 1881 in no important 

 particular. 



Dresden (private observatory of Baron v. Engelhardt) : Thirty five ob- 

 servations of 3 comets and 110 observations of 37 planets have been 

 made and published, and some important changes have been made in 

 the instruments.* 



Dusseldorff: In 1882 57 observations of 18 asteroids were made, and 

 since 1847 1,102 observations of 141 planets. 



Hamburg: The zone +80° to +81° has been completed, and the ob- 

 servatory has begun the zone between —15° and —16°. The divided 

 circle of the meridian circle has been replaced by a new one, made by 

 the Bepsolds. 



Hereny {Hungary) : In 1882 the spectra of 147 fixed stars and 2 comets 

 were observed, besides miscellaneous observations. The stellar-spec- 

 trum observations are classified in a table giving the types to which the 

 stars belong. 



Kalocsa {Hungary) : Begular drawings of the Sun (22 centimeters in 

 diameter) have been made during the year, and also a determination 

 of the latitude and the (telegraphic) longitude from Vienna. 



Karlsruhe: The instruments have been removed from Mannheim to a 

 provisional observatory in Karlsruhe. With the 6-inch equatorial a se- 

 ries of measures of star clusters is kept up. The Reichenbach circle 

 (made in 1811) has received thorough repairs and is employed in a de- 

 termination of the places of stars south of the equator ; the objective is 

 only 3 inches, and the stars selected are therefore 8 magnitude or 

 brighter. Each star is to be observed six times, and Dr. Valentiner 

 hopes to determine the places to 3 .01 and 0".15. 



Kiel: The equatorial has received a thorough repairing by the Bep- 

 solds and has been used by Dr. Lamp in a series of Victoria and Sappho 

 observations for Dr. Gill. Dr. Krueger gives in a paragraph some 

 criticisms of the programme prepared by Dr. Gill, which deserve atten- 

 tion. Dr. Pape's observations for the determination of the equinox, 

 I860, are printed. The printing of the zone +55° to +65° has been be- 



*A very interesting illustrated account of Baron v. Engelhardt's observatory in 

 given in Sirius for November, 18d3.
