CHAPTER XIX. 



MISCELLANEOUS INVESTIGATIONS 

 Between the Years 1780 and 1800. 



804. The present Chapter will contain notices of various 

 contributions to our subject wliicli were made between the years 

 1750 and 1780. 



805. We have first to mention two memoirs by Prevost, en- 

 titled, Sur les principes de la Theorie des gains fortuits. 



The first memoir is in the volume for 1780 of the Nouveaux 

 Memoires .., Berlin ; the date of publication is 1782: the memoir 

 occupies pages 430 — 472. The second memoir is in the volume 

 for 1781 ; the date of publication is 1783 : the memoir occupies 

 pages 463 — 472. Prevost professes to criticise the account of the 

 elementary principles of the subject given by James Bernoulli, 

 Huygens, and De Moivre. It does not seem that the memoirs 

 present anything of value or importance ; see Art. 103. 



806. We have next to notice a memoir by Borda, entitled 

 Memoir e sur les Elections an Scrutin. 



This is in the Hist....de V Acad.... Paris for 1781 ; the date of 

 publication is 1784 : the memoir occupies pages 657 — QQo. 



This memoir is not connected with Probability, but we notice 

 it because the subject is considered at great length by Condorcet, 

 who refers to Borda's view ; see Art. 719.
