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

 m 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. N. B.

The ASTRONOMICAL SOCIETY'S STAR CATALOGUE, which, according 1o Sir John Herschel, ' put the astronomical world in 

 possession of a power which may be said, without exaggeration, to have changed the face of sidereal astronomy.' 



' In 1827 the Astronomical Society of London rendered an important service to practical astronomy, by the publication 

 of a general catalogue of stars, fouudt d upon the most celebrated catalogues that have been executed since the middle of 

 the XVIII. century. This catalogue contains the places of 2,881 stars, reduced upon a uniform system to Jan 1st, 1830. 

 In addition to the mean place of each star, the constants for computing its apparent place, according to Bessel's method, 

 are also inserted. The introductory explanation is by Francis Baily, to whom was assigned the important task of selecting 

 the most trustworthy values of the uranographical corrections. The calculations were executed under the superintendence 

 of Lieut. Stratford,' Prof. R. Grant.

' The leading idea of Baker's work is the solution of biquadratic equations (and those of a lower degree) by a gometrical 

 construction, a parabola intersected by a circle. The method is distinguished from that of Descartes by not requiring the 

 equation to be previously deprived of its second term. The general principle is worked out in great detail. . . . Some 

 account of the work is given in the Transactions of the Royal Society.' D. N. B.
