REPORTS OF EUROPEAN OBSERVATORIES. 581 



made on double stars and red stars. Saturn's satellites were observed 

 ou 24 nights from the 30th of August. 



GOTHA OBSERVATORY. 

 (Dr. A. KRUGER, Director.) 



Since the last report the observations of the zone stars between 55° and 

 05° X. declination have been continued. Mr. A. Donner resigned his 

 position as assistant, and was succeeded by Dr. L. de Ball. The num- 

 ber of zones has been increased to 043, and the observations now number 

 32,500. One or two nights will be sufficient to close the series. The 

 computation of the observations was continued. The deduction of the 

 transits and of the apparent declinations is nearly completed, as also 

 tables of reductions to the mean positions for 1875. A copy was made 

 for publication of the original observations. The original observations 

 will be published at the earliest possible moment. 



HAMBURG OBSERVATORY. 

 (Dr. GEOiiGRuEMKER, Director.) 



Owing to prevailing unfavorable weather — only 181 nights during the 

 entire year could be utilized, and in most cases oidy in part, for observ- 

 ing — the work of cataloguing stars and nebulae progressed but very 

 little. The meridian circle was employed in observations on time and 

 on positions of fixed stars and planets. Positions of nebulas were de- 

 termined with the equatorial. 



The usefulness of the IV Division of the "Seewarte" (chronometer- 

 testing institute), which was placed under the observatory, has satisfac- 

 torily increased. On occasion of the second competitive chronometer 

 test, instituted by the imperial navy department, 51 chronometers were 

 exhibited by 1_J German manufacturers, 7 of whom reside in Ilamburg- 

 Altona. 



The time signals had to be discontinued for some time on account of 

 the damage done to the apparatus during the severe storm of March 8. 

 The time-ball stations at Cuxhavenand Bremerhaven have worked very 

 satisfactorily. 



Dr. (I. Koch resigned his position, and was succeeded by Dr. Karl 

 Schrader, of O'Gyalla, Hungary. 



KREMSMUNSTER OBSERVATOR V. 

 (G. STRASSER, Director.) 



The meridian circle was furnished with new microscope and new hor- 

 izontal level. 



Observations on the Moon and moon-culminating stars were continued. 



Planetary observations were made partly with the meridian instru- 

 ment and partly with the refractor.
