A collection and reprint of those astronomical tables most often used (some rare and difficult to obtain), and all revised 

 or re-computed. 



' His revision of star-catalogues alone entitled him, in Sir John H^rschel's opinion, to rank among the greatest 

 benefactors to astronomy.' D. N. B. 



5921 The CATALOGUE of STARS of the BRITISH ASSOCIATION for the ADVANCEMENT of 



SCIENCE : containing the mean RIGHT ASCENSIONS and NORTH POLAR DISTANCES of 8,377 

 FIXED STARS, reduced to Jan. 1, 1850, with their Annual Precessions, Secular Variations, and 

 Proper Motions, and Logarithmic Constants for computing Precession, Aberration and Nutation ; 

 also Preface on their Construction and Application, 4to. boards, uncut (VERY SCARCE), 4. 15s 1845 



The celebrated British Association Star Catalogue, revised, after the author's death, by W. S. STRATFORD, 

 JAMES CHALLIS, FF.R.S., and others. 



' Still in high repute . . . The value of this catalogue was much enhanced by the uniform system of nomenclature 

 adopted throughout. This material improvement was the result of Btily's severe labours in revising the constellations, 

 and marshalling into recognisable order the stars composing them.' Miss Agnes M. Clerke. 



'The materials of its construction are derived from all the trustworthy catalogues that have been executed since the 

 time of Bradley. This catalogue is distinguished from the catalogue of the Astronomical Society in two important 

 particulars. In the first place, the secular variation of precession, both in the right ascension and declination is given 

 for each star. Secondly the proper moti ns of the stars are assigned with as great a degree of nearness to truth, as the 

 existing state of sidereal astronomy allowed. This catalogue has proved of vast service to astronomers in every part 

 of the civilised world. Prof. R. Grant.

1 Baily's merits as a writer of life-contingencies were undoubtedly very great. The subject was by him first presented 

 in a symmetrical form ; a uniform system of notation was introduced ; and to a perspicuous and comprehensive view of 

 the labours of his predecessors the results of much original research were added.' D. A'. P>.
