ASTRONOMY. 353 



Professor Holdeu and Father Hagen bavo also derived the places of 

 437 southeru stars for 1850.0 from Washington transit-circle observations, 

 and tbese places have been compared Avith positions given in the Cape 

 Catalogne for 1880, the Cordoba Zones, and Yarnall's Catalogne. The 

 comparisons are i)rinted in the volume referred to above, and will be of 

 value in deducing the relations of the various systems adopted. 



The ^^anonymous" stars of Yarnall's Catalogne* — " Prof. E. Millosevich 

 has i^ublished a useful contribution to exact astronomy in his paper. 

 Sidle iStelle horeali Jino «— 1° inclusivo dette '•Anonymous'' del Catalogo di 

 Tarnall (Washington, 1878). It appears that between the limiti^ +90° 

 and— 1° declination, Yarnall's Catalogue contains 732 stars which are 

 designated as anonymous. Professor Millosevich has carelullj' gone 

 through these, comparing them with the DM., or with the catalogues 

 of Weisse, Eiimker, Struve, Lalande, or Oeltzen's Argelander, and has 

 succeeded in almost every case (sometimes by making conjectural cor- 

 rections to Yarnall's places) in identifying the star in the Washington 

 Catalogue. The paper also contains a comparison of the estimates of 

 magnitude made by the Washington observers and by Argelander in 

 the case of these auonymous stars. After applying a systematic cor- 

 rection of -I-0-3 of a magnitude to Y'arnall, Professor Millosevich finds 

 that there are 33 stars which differ by 0-9 of a magnitude or more in 

 the two catalogues, and gives a list of these with their places for 1800*0, 

 as there is a strong jiresumption that they will prove to be variables. 

 Taken in conjunction with- Holden's List of Errata in Yarnall {Astron. 

 N'aehr., No. 25G1), Professor Millosevich's paper is a useful addendum 

 to the Washington Catalogue for 1860." (Observatory.) 



Professor Frisby, of the Naval Observatory, is now at work upon a 

 third edition of YarnaWs Catalogue, in which it is intended to correct all 

 the errors thus far detected. 



Harvard College catalogue of 1,213 s/ors /or 1875. — "This catalogue 

 contains the results of observations made during the years 1870 to 1879 

 with the meridian circle of the Harvard College Observatory, the stars 

 observed being chiefly those required for the revision of the Durch- 

 mnsterung for the Kone between the parallels of declination +50° and 

 -l-55<='. The star places employed as points of reference were taken 

 from the list given in Publication xiv of the Astron. Gesellschaft. The 

 right ascensions and declinations published in the catalogue are de- 

 rived from a discussion of the results obtained during the whole period 

 covered by the observations. They are given in their present form for 

 the purpose of making them immediately available in advance of the 

 publication of the volume which is to furnish the details of the investi- 

 gation, viz, volume xv of the Annals. The observations were nearly 

 all made by Professor Rogers, who has also had charge of their reduc- 

 tion and publication, — a statement which is a sufficient guarantee for
