SIS History of Astronomy for the Year 1803. 



tending even in America. Don Antonio de Robrcdo has 

 sent nie from the Havannah minute calculations of the 

 eclipse ot" the sun, on the 10th of February 1804, made by 

 the analytical methods of M. Dusejour, for every covmtry of 

 the earth, with all the dimensions of the curves of illumi- 

 nation. These calculations, more extensive and more exact 

 than those in the Connoissance des Temps for the year 12, 

 arrived too late to be inserted in that work ; which I much 

 regretted. 



The French government has resolved to re-establish the 

 mission to China, which is equally useful to the sciences 

 and to political relations. One of our ablest astronomers 

 has formed the project of going thither ; and however great 

 his utility may be here, I did not oppose this plan of going 

 to a distance from us, in order that he may still be of more 

 service to us. 



The duice of Brunswick has resolved to cause an observa- 

 tory to be constructed. Baron von Zach has been at Bruns- 

 wick for that purpose ; and I have thanked, in the name of 

 all astronomers, the prince who increases the number of 

 heroes, protectors of astronomy, whom I have mentioned 

 in the preface to mv work on that subject. 



The Italian republic has requested an astronomer to co- 

 pperate v/ith M. Ciccolini in the observations made in the 

 institute of Bologna. 



M. Vassalli-Eandi has requested that the observatory of 

 Turin mav be put into a state of activity. 



Th« margrave of Baden, having taken possession of Man- 

 heim tin the 23d of November 1802, preserved the instru- 

 ments of the observatory; and M. Bary has announced to 

 nie a new series of observations. 



My Bihl.'iograjjkle Astrojiomique appeared on the 5th of 

 June in a quarto volume of 900 pages. It contains as large 

 d. catalogue, as I was able to make, in the course of thirtv 

 years, of all the astronomers and all the works on astronomy 

 which have appeared for two thousand years. 



Baillv's large History of Astronomy terminated at 1781 : 

 I have continued it to the end of 1 802. 



M. Goudin has given a new edition of his Astronomical 

 Memoirs. 



On the 17th of March the Board of Longitude published 

 the Connoissance des Temps for the year 13, which contains 

 every thing relating to astronomy that has been done in the 

 countries where it is cultivated : the history and observa- 

 tions of the new planets and of the last comets; a new ca- 

 laloffuc, which make* the number of the stars known to be
