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

 141 a syniiiietrieal form ; a uniform system of notation was introduced ; and to a perspicuous and comprehensive view of 

 the labours of liis predecessors the results of much original research were added .'—/). N. D.

Tiie Astronomical Sooietv's Star Catai.ooue, which, according to Sir John Herschel, ' put the astronomical world in 

 I)OssHssi')n of a power which may be said, without exaggeration, to have changed the face of sidereal astronomy.' 



' In 1S27 the Astronomical Society of London rendered an impoitant service to practical astronomy, by the publication 

 of a genenil caUilogue of stars, foundtd upon the most celebrated catalogues that have been executeil since the middle of 

 the XVIH. century. This catalogue contains the places of 2,S8i stars, reduce<l upon a uniform system to Jan 1st, 1830. 

 Ill aildition to the mean place of aich star, the constants for computing its apparent place, according to Bessel's method, 

 are also inserte<l. The intro<luctory explanation is by Francis Baily, t<» 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.'— i'ro/. li. Uruut.

* The lpa<ling idea of Baker's work is the solution of biquadratic equations (and tho.se 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 previouslyileprived of its second term. The general principle is woiked out in great detaih . . . Some 

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