M. Goudiu has catculat.d several of these observations, 

 by aa analvtical method derived from that which he pub- 

 lished in order to calculate, by anticipation, the phases of 

 an eclipse for all the countries on the globe. 



T\\t\ have inserted in the CovnoHsance dcs Terns th(; chart 

 of th.e eclipse of the sun on the 29ih of November 1807 ; 

 hirt they have omitted ti-.e general disposition calculated for 

 all latit:udes by M. Goudin, and that of the principal cities 

 by M. Duvauccl; they will be placed in the volume for 

 1809, which will be published previous to that eclipse. 



M. Delaplace has given in the Journal de Physique some 

 memoirs in which he shows that the adhesicn of bodies, 

 placed upon the surface of a t^uid, corresponds with the 

 capillary attraction of which he has given the mathematical 

 theory,' and he shows the method of calculating this adhe- 

 sion according to the experiments of Messrs. Haiiy and 

 Achard. The principle of attraction between the molecule* 

 of bodies decreasing with an extreme rapidity, which ex- 

 presses the rai)illary phenomena, is also the cause of the 

 chen.ical affinities ; it produces an influence of masses, the 

 effects of wliich M. Berthollet has developed in a new and 

 jhappy manner. 



m'. Anago, seeing that the light reflected by the satellites 

 gives the same velocity with the aberration of the stars, 

 concludes from this that the velocity does not change. 

 M. Anago found the same thing with terrestrial objects : 

 he made experiments with a prism applied to the mural qua- 

 drant, upon the light of the sun, the stars, and terrestrial 

 objects ; and he found that the velocity of the light is the 

 same in every circumst^ince. 



M. Hal ma, bookseller to tlie empress, has undertaken a 

 translation into French of the Almagestus of Ptolemy. 



M. Humboldt is busy at Berlin in editing his Historical, 

 Physical, and Political Travels ; he is also occupied with the 

 horary variations of magnetism. M. Oltmanns labours along 

 with luni ; this young geometrician calculates with as much 

 zeal as intelligence; he is about to publibh a volume of 



astruuuancal
