mers whether this examination ought to be extended to the 

 stars of the fourth, fifth, and sixth magnitudes. A rigorous 

 investigation to that extent insuring the certainty of not 

 one having been omitted, would require considerable labour. 

 Next come the moon-culminating stars, or those stars which 

 being near the parallel of the moon at the time of her culmi- 

 nation are likewise not far distant from her in time. It was 

 originally not my intention to give them. However success- 

 ful the observations have been by the ready publication of 

 them in Prof. Schumacher's Astr. Nachr., they will then only 

 be of use if a single catalogue only is annually published. 

 Nothing but the request of a much esteemed correspondent, 

 in consequence of the fear entertained in the beginning of this 

 year that the publication of such a catalogue would be inter- 

 rupted, has induced me to give the present one; should, how- 

 ever, another catalogue containing, perhaps, a greater num- 

 ber of bright stars be sent from England, I would request 

 that this one should be laid aside. Its construction has been 

 performed rather hastily ; more convenient stars might per- 

 haps have been selected, especially for the second limb of the 

 moon. 



In the application of it for ascertaining longitudes even with 

 only moderate transits, it will be adviseable to consult prin- 

 cipally the excellent paper by Prof. Nicolai, Astr. Nachr. ii. 

 No. 26, and those by Prof. Bessel and M. Hansen on the cal- 

 culation of the horary motions of the moon, Astr. Nachr. ii. 

 No. 33. 



The notation and the places of the stars, both of the moon- 

 culminating stars and of those mentioned in the list of occulta- 

 tions which follows, have been taken from the excellent Cata- 

 logue of zodiacal stars, by which Mr. Baily has conferred a 

 valuable benefit on the astronomical public. 



From this Catalogue all those stars have been inserted 

 which will be occulted during the time of the moon's being 

 above the horizon, while the sun is below it. Sometimes those 

 have likewise been mentioned which are so nearly approached 

 by the moon's limb, that a calculation only could decide whether 

 an occultation would take placeor not. For bright stars, the 

 occultations which happen in the day-time, especially those 

 of a Tauri, have likewise been inserted. Some immersions and 

 emersions which happen below the horizon of Berlin, have still 

 been given, because they may be visible in other places. 



The headings show the contents of the columns of this 



section. The two columns " Ort " (place) indicate in what 



point of the moon's disc the immersions and emersions take 



place : the degrees being counted from that point of the disc
