582 REPORTS OF EUROPEAN OBSERVATORIES. 



lianas, Jupiter, and Neptune, were observed with the meridian cir- 

 cle. 



Observations were made on 12 minor planets. 



Fifty comparison stars of planets were determined with the meridian 

 circle, for which purpose 160 positions had to be taken. A large num- 

 ber of positions of fixed stars were observed, but have not yet been 

 reduced. 



The transit of Mercury was invisible on account of clouds, and the 

 same occurred on occasion of the eclipse of the Pleiades. 



UNIVERSITY OBSERVATORY, LEIPZIG. 

 (Prof. C. BftUHNS, Director.) 



Xo change has taken place in the personnel. The following gentle- 

 men are volunteer observers: Messrs. (Jautier, Dr. Hiltiker, von Dan- 

 kelnian, Keiser, Meier, Regler, Schneider, and Schnauder. 



The following instruments were procured: A Moyerstein universal 

 instrument, used by Dr. Borger in his expedition to East Greenland; a 

 new registering apparatus by Fness, including a polarizing relay. Tel- 

 ephonic connection has been established. 



Mr. Weinek, who is still engaged in the discussion of the photographic 

 views of Yenus, observed with the meridian circle, and Dr. Peter, with 

 the equatorial: 23 stars in RA and Deck were observed, and 12 stars in 

 1 1 A for a discussion by Mr. Gill. Minor planets were observed with the 

 meridian circle. 



Preparations and experiments were made for zone-observations. Mr. 

 Weinek observed the transit of Mercury with the 6-foot refractor, and 

 took 44 photographic views of the planet by means of the photohelio- 

 graph, which was used, in 1S74. in Kergnelen Island. 



Dr. Peter, with the equatorial, made in 99 nights, 1S1 observations 

 on 51 minor planets and L2 observations on comparison stars. 



Tempel's comet was invisible, and observations on Swift's comet 

 failed on account of an error in the dispatch announcing the discovery. 



The lirst contact in the transit of Mercury, an eclipse of the Moon, 

 and eclipses of the satellites of Jupiter, were observed. 



The changes supposed by Dr. Klein to have taken place in Hyginus 

 in the Moon, failed to be detected in drawings made by Dr. Peter for 

 the purpose. 



Mr. Leppig, with a small Frauenhofer refractor, observed on sun- 

 spots; he also observed the transit of Mercury, the eclipse of the 

 Moon. etc. 



Mr. Schneider practiced with the 0-foot retractor and made drawings 

 of nebiila-. Mr. Dietrich examined the photometer, but did not com- 

 plete a series of observations. 



The lirst volume of the "Leipzig Beobachtungen* will be published 

 shortly.
