ASTRONOMY. 



187 



the zone observations were read. The following account is taken from 

 Dr. Dreyer's report. Much progress has been made since then. 



80-75. Kasan. . Observations finished, except a few; reductions far 

 progressed; printing commenced. 



Dorpat. Only 920 observations yet to be made; more than half 

 the reductions to 1875.0 finished. 



Christiania. Zones finished; about 90 per cent, reduced. 



Gotha (formerly Helsiugfors). Zones finished; reductions far 

 advanced. 



Cambridge, U. S. Observations finished ; reductions progress- 

 ing well. 



Bonn. About 5,000 single observations remain to be made ; re- 

 ductions far advanced. 



Lund. Observations commenced in September, 1878 ; the re- 

 ductions are progressing with the zones. 



Leiden. Finished. 



Cambridge (England). About 4,000 single observations to be 

 made yet. The mean places are calculated up to the end of 

 1874, apparent i^laces to the end of 187G. 



Berlin. Not yet commenced. 



Berlin. Finished, but not yet reduced. 



Leipzig. Zones finished ; E. A.'s almost all reduced to 1875. 

 zeros for declinations partly computed. 



Leipzig. Has been commenced. 



Albany. Observations were commenced in August, 1878. 

 4- 1 to - 3. Nicolajeff. Much interrupted by the Eusso-Turkish war. 



A second edition of the Washington Catalogue of Stars has been 

 issued. Since the first edition was published in 1873, Professor Yar- 

 iVALL had accumulated many observations, which he, before retiring 

 froin the Observatory, embodied in a second edition. Many stars which 

 had only been observed once or twice, either in right ascension or de- 

 clination, were thus re-examined. The author died suddenly, on Feb- 

 ruary 27, 1879, the complete volume only reaching him a few moments 

 before his death. 



Dr. Robinson has published "Places of 1,000 Stars, observed at the 

 Armagh Observatory." The stars are those of the fainter ones in the 

 "Histoire Celeste" (nearly all between Gth and 7.5 mag.), which have 

 not been recently observed at other observatories. The instruments at 

 Armagh not being optically powerful enough for this work, the mural 

 circle was furnished with a new telescope having an object-glass of seven 

 inches aperture. The observations were all made by the Eev. Cn. Faris, 

 in the years 18G8-'7G, each star being observed four or five times. Only 

 the mean results are given. , 



The first volume of the second series of the " Annales de I'Observa- 

 toire de Bruxelles" contains an " Uranometrie Generale," by M. Hou-
