Hamburg Observatory. 



Dr. Georg Rumker, Director. 



The zone observations (zone 80-81 N. P. D.) were continued on 

 forty-five nights. Mars was observed fourteen nights. Observations 

 of nebula?, star-spectra, comets, etc., were made with the Equatorial. 

 The Time-ball Stations of Cuxhaven, Bremerhaven, etc., are pro- 

 vided with time-signals, and the Chronometers of the Priifungs-Insti- 

 tut are compared. Dr. Georg Koch is assistant. 



University Observatory, Leipsic. 



Professor C. Bruhns, Director. 



Herr "Weinek observes with the Meridian Circle. Mars was ob-

 served. Dr. Peter, with the Equatorial, has observed on 129 nights, 

 making 176 observations of 35 asteroids, 84 observations of 6 com- 

 ets, etc. Herr Leppig has observed sun-spots on 195 days with the 

 small Equatorial. Herr Harzer has drawn a number of nebula? with 

 a 4|-foot Refractor, and with the Comet-seeker. 



Herr Harzer has investigated the orbit of Brorsems comet from 

 1842 to 1846. The first volume of "Leipsic Observations," contain- 

 ing Observations of Nebula? and Double Stars, is printing. 



The Transit-of- Venus observations are computed at this observa- 

 tory for the German Commission.

The instrument is a Steinheil Refractor, of 4 inches aperture, and 

 154 observations of 38 asteroids have been made. 



University Observatory, Lund. 



Professor A. Moller, Director. 



Dr. Lindstet, assistant, has investigated the division errors of the 

 Meridian Circle. Mars was observed on ten nights. Double stars 

 and comets have been observed with the Equatorial. 



University Observatory, Milan. 



Professor M. Schiaparelli, Director. 



Eight hundred and forty measures of double stars have been made 

 with the 8A-inch Equatorial (Mekz). 2 2165, =IIercidis 281 B, was 

 found to be triple. Comets were also observed, and the surface of 

 Mars studied, and a map made.
