A MOST INTERESTING MANUSCRIPT COLLECTION ! 



14879 : MANUSCRIPT COLLECTION, containing Hundreds of Mathematical and Astro- 

 nomical Problems and Propositions by him, his Copy and Correspondence in Connexion 

 with the ' Ladies' Diary ', and his extensive and very interesting Correspondence with 

 Mathematicians of the Time, including Draughts or Fair Copies of his own Letters, 

 5 vols, folio, boards, £10. 10* 1730-58 



This very interesting Manuscript Collection is important from the number of oripinal problems either suggested by the 

 author himself or by his correspondents which it contains, together with their solutions. It should form no unimportant 

 contribution towards the history of mathematics during the time it covers. 



The following is a list of the more important autograph letters contained in it :— Henry Beiohton, f.r.s., editor of the 

 'Ladies' Diary', 1713-44 : Sir Francis Blake, f.r.s., 1708-80 (21 long and interesting letters, ivith problems): Alexander 

 BuLLER, of Philadelphia, 1741 : Martin Folkes. f.r.s., antiquary, 1690-1754 (3 Utters): Robert Heath, mathematician, 

 editor of the ' Ladies' Diary ', 1744-53 (3) : John Landen, f.r.s., 1710-90 (2 letters on his Theorem, one long and very interest- 

 ing): John Michell, pr., f.r.s., Woodwardian Prof. Geology, astronomer, 1724-93 : John Muller, Prof. Fortification and 

 Mathematics, R. Academy, Woolwich, the author's rival, 1699-1784 (3 letters, one with a long reply which may have caused 

 the enmity between the two): John Robertson, f.r.s., first master R. Naval Academy, Portsmouth, 1712-76: Anthony 

 Thacker, editor of the ' Ladies' Diary ' (4). 



It also contains the manuscript of the following memoirs by Simpson : Some Account of M. Silvabelle's Tract on the 

 Precession of the Equinox (pp. 3) ; Farther Attempt to facilitate the Resolution of Isoperimetrical Probleins (pp. 4): Of 

 the Fluents of Multinomials and Series affected by Radical Signs, which do not begin to converge till after the Second 

 Term (p. 1). There is also Simpson's caustic reply (apparently never published, having nunierou.s cancellations and cor- 

 rections) to John Muller, who accused him of having pirated his worthless 'Elements of Mathematics', and the further 

 correspondence on this quarrel.
