588 Uijlory of Ajlronomy for 1708. 



will appear^ together with 3060 declinations which I have 

 fent to M. von Zach, in an important work he is about to- 

 publifti on aftronomy, in two volumes o&avo, and of which 

 two thirds are already printed. 



M. Bode brought from Berlin drawings of his thirteenth- 

 chart of the ftarry heavens. There will be twenty in the 

 whole ; and this colle&ion, of the utmoft value to aftrono- 

 mers, will contain 13,000 ftars, or 8000 more than ever 

 were reprefented before. He has reduced 3000 of Lacaille's 

 ftars, and has obferved 1500 himfelf to fill up vacancies; C. 

 Lefrancais fupplied him with the reft. There will be 

 found in it the 2000 nebulae of Herfchel, and from 

 five to fix hundred double ftars of that celebrated aftrono- 

 mer. We have formed two- new conftellations, the Prefs of 

 Guttemberg, and Mongorfier's- Balloon. 



M. Wurm came to meet us from Wirtemberg, the diftance

 gratuity of 800 livres. He aflured me that he would ftill col-

 that this undertaking, which muft enfure correftnefs to our 

 calculations for more than a century, may be rendered as 

 perfeft and ufeful as poffible. 



Mefir?. Klugel, Gilbert and Piftor, came from Halle, & 

 celebrated univerfity in the king of Pruffia's dominions, and 

 M. Schaubach from Meinungen. M. Seyffer, of Gottin- 

 gcn, promifed us fome observations and calculations, of 

 which we are in want. M, {Confer brought with him a 

 new pholometer to meafure the light of me ftars, and a re- 

 flecting felenoftate, which is a very ingenious machine. M. 

 Feer, of Zurich, brought a chart of the Rinthal, conftru&ed 

 from obfervation3 with a fextant. All thefe philofophers 

 agreed to recommend the new fyftem of mcafures, and to 

 employ the mean time and decimal reckoning in their cal- 

 culations. M. Seyftert, of Drefden, gave me a ftop watch, 

 with the hour plate divided according to the decimal method 

 which was executed by himfelf. We went to the top of the 



mountain
