 it is reproduced in the second Supplement to the Theorie...des 

 Proh. pages 1 — 25. 



928. In the Connaissance des Terns for 1822, which is dated 

 1820, there is an article by Laplace on pages 346 — 348, entitled, 

 Application dii Calcul des ProhahiUtes aux operations geodesiqnes 

 de la meridienne de France: it is reproduced in the third Supple- 

 ment to the Theorie . . ,des Proh. pages 1 — 7. 



929. We have now to speak of the great work of Laplace which 

 is entitled, Theorie analytique des ProhahiUtes, This was published 

 in 1812, in quarto. There is a dedication to Napoleon-le-Grand ; 

 then follow 445 pages of text, and afterwards a table of contents 

 which occupies pages 446 — 464 : on another page a few errata 

 are noticed. 



The second edition is dated 1814, and the third edition is 

 dated 1820. 



The second edition contains an introduction of cvi. pages ; then 

 the text paged from 3 to 484 inclusive ; then a table of contents 

 which occujiies pages 485 — 506 : then two pages of errata are 

 given. 



The pages 9 — 444 of the first edition luere not reprinted for 

 the second or third edition ; a few pages Avere cancelled and re- 

 placed, apparently on account of errata. 



The third edition has an introduction of CXLII. pages ; and 

 then the remainder as in the second edition. There are, however;, 

 four supplements to the work which appeared subsequently to the 

 first edition. The exact dates of issue of these supplements do not 

 seem to be given ; but the first and second supplements were 

 probably published between 1812 and 1820, the third in 1820, 

 and the fourth after 1820. Copies of the third edition generally 

 have the first three supplements, but not the fourth. 



930. Since the bulk of the text of Laplace's work ivas not 

 reprinted for the editions which appeared during his life time.
