Analyses of Books. 



Philosophical Transactions of the Royal Society of London, for 



1824. Part I. 



Of the papers contained in this part of the Philosophical 

 Transactions, two are given entire in the present number ; we 

 purpose to reprint two others, of similar value, in the ensuing 

 numbers of the Annals ; of three others copious reports have 

 already been presented to the reader: whilst the remainder, being 

 on subjects of Astronomy and Mathematics, cannot usefully be 

 epitomized. We shall, therefore, confine our extracts in this 

 place to the titles of these papers.
