STARS IN COMA BERENICES. 345 



ducedto iSooby Von Asten's " Neue Hiilfstafeln zur Reduction der in 

 der Histoire Celeste enthaltenen Beobachtungen," Vierteljahrsschrift 

 der Astronomischen Gesellschaft, appendix to Vol. 4. Account was 

 taken of the errata published in the introduction to the Paris cata- 

 logues, by Peters, and by others.

 of Fixed Stars made by Joseph Lepaute d'Agelet * * * 

 with a catalogue * * * by B. A. Gould. Washington, 1866. 



The mean of the separate observations given in the catalogue was 

 used. 



(5) BESSEL, 1825. Astronomische Beobachtungen 

 auf der Koniglichen Universitats-Sternwarte zu Konigsberg, 

 for the years 182 1 to 1833. 



Weisse's Catalogue of Bessel's Northern Zones was used only as 

 index to the original observations, which were reduced anew by the aid 

 of Luther's tables in " Astronomishe Beobachtungen auf der Konig- 

 lichen Universitats-Sternwarte zu Konigsberg," Abt. 37, 2*®'' Teil. 

 An explanation of the necessary formulae there given, which are 

 similar to those in use with Von Asten's tables, will befoundin Arge- 

 lander's Bonner Beobachtungen, Vol. I, p. xxxvi. Account was taken 

 of the errata to the zones recorded in Part I of the volume containing. 

 Luther's paper. The star numbers in the Tables, Sect. Ill of the 

 present paper, are those of Weisse's catalogue.

 annis 1822 ad 1843. Petropoli, 1852. 



Positions were taken from the " Catalogus Generalis " beginning 

 on page 235, and the mean date was used as there given in column 

 nine, unless a B was found in that column. This means that a 

 certain proper motion, deduced from comparisons with Bradley, was 

 included in the reduction, but as its value is not given, it was 

 deemed best, in such cases, to take the star's position directly from 

 a " Catalogus Specialis " in the preceding part of the volume. Refer- 

 ence to the page will in general be found in column eleven of the 

 " Catalogus Generalis." The " Correctiones Ultimse " given on pp. 

 360 ff. were not applied in such cases. ,
