liaS Hijlory of yijli-otiomy for the Year l8oi. 



earth and moon, as well as the variations of the equator an3 

 orbit. 



M. Philippides, born at Mount Pelion in ThefTaly, who 

 attended the courfe of altronomy at the College de France 

 in 1794, and who is now at Jafli with the hofpodar of Mol- 

 davia, propofes to piibiiOi ill Greek the Abridgement of my 

 Aftronomy : he has already publiflied various works, for the 

 purpofe of endeavouring to propagate inftru6lion in his 

 country. 



Three-fourths of the two lafl: volumes of Montiicla's Hif- 

 tory of the Mathematics are printed. This work will con- 

 tain the hiftory of agronomy, optics, and navigation; to 

 which I have been obliged to make great additions in confe- 

 quenceof the too premature death of the learned author. 



M. Von Mnrr, of Nuremberg, who has manufcripts of 

 Regiomontanus, the firll refiorer of aftronomy before 1500, 

 has caufed a page to be engraven, an exaft fac-fimile of the 

 charadter of the manufcript : he others to fell thefe manu- 

 fcripts for 2400 francs J they would be a treafure to a large 

 library. 



The aftronomical poems of Ricard, Lemiere, and Fontanel, 

 had before (liown how far a view of the heavens is capable 

 of exciting poetical enthufiafm. C. Gudin has again proved 

 it by a poem, which contains both the h'ftory ot aftronomy 

 and a delcription of the heavens, and which diiplays as much 

 correftnefs as elegance. 



This year geography alfo has made confiderable progrefs. 

 Tranchol is conftrufting a map of the four united depart- 

 ments on the fcale oF a line to 100 toifes : a furvey is taking 

 of the country between the dige and the Adda, Piedmont, 

 Swabia, and Swiflerland 5 and the minifter at war caufed tl>c 

 details to be inferted in the Moniteur of Auguft 14; 



C. Henry, who has been invited to Munich to eonftru6t the 

 map of Bavaria, informs me in a letter that the topogra{)hical 

 part is in great forwardnefs ; a baleof 21,649 metres or T 1,108 

 toifes has been mcafured : it is the longeft ever nieafured. 

 The large triangles around the capital are already in part 

 clofed. There are fome the fides of which will be from 

 15 to 20 leagues, and even more. Lie bus already fwept 

 the horizon feveral times with hi? circle, and with aftonifhing 

 precifton. The laft fweep was compofed of (ix angles; the 

 fum of which when reduced was not in excels, bui"8-ioths 

 ofafecond in 360 decrees; and yet the circle he ufed was 

 not very good. To make up as much as poftible for what 

 may be wanting in regard to precifion, he multiplies his ob- 

 fer\'ations : he never makes lefs than 15 conjugate obfcrva-
