This society was originally founded by Laplace, Berthollet, Gay-Lussac, Biot, Humboldt, de Candolle, and Collet- 

 Descostils at BerthoUet's country house in Arcueil, near Paris, where its members were to meet twice a month. 



The work contains memoirs by Laplace (1), Berthollet (20), Gay-Lussac (10), Thenard (10), Biot (9), Humboldt (3), 

 Malus (3), Dulong (2), de Candolle (2), Descostils (2), Berard (1), and Arago (1). That by Laplace is 'Sur le mouveraent 

 de la lumiere dans les milieux diaphanes ' ; among Gay-Lussac's is the important one ' Sur la combinaison des substances 

 gazeuses ' (vol. II. p. 207), in which he first expounded the law of volumes named after him. One of Dulong's memoirs 

 gives an account of his discovery of chloride of nitrogen (the most powerful and unstable explosive known), which cost 

 him an eye and three fingers. 



The above copy belonged to F. J. D. Arago, a MS. note in vol. I, in Prof. Story-Maskelyne's handwriting, reading : 

 ' M, Arago's sale. 1854. 2s . S. M.'

 otherwise a sound and clean copy) ; RARE, £1. I5 Bononice, Jac. Montiits, 1650 



The author's first published work. It is rare, and was unknown to Poggendorff, Prof, de Morgan, Graesse, Brunet, and 

 the author's biographer in Biogr. Gen., nor was there a copy in the Libii Library. 



The work is of interest as being entirely devoted to fractions. According to G. Libri, the author's Geometrice Speciosoe 

 Elementa, published in 1659, dealt with Newton's binomial theorem— a palpable mistake, as Sir Isaac Newton did not 

 publish it until 1669 in his De AnaZysi per Aequationes.
