tiijlory of AJlronomy for the Year l8oi. 20^ 



the vitrid mafs was minutely examined, but no metallic 

 globule was vifiblc. The mixture before fufion was mag- 

 netic, owing to the oxide. This property was now en- 

 tirely loft. 



The heat of this experiment was urced moderately, that 

 time might be given for the exertion of any affinity, if fuch 

 exifted, betwixt the iron and the carbonic acid, or betwixt 

 the oxide of iron and the carbonaceous part of the acid. No 

 portion of metal being revived, I conceived this a moft con- 

 clufive proof of the nondecompofition of the carbonic acid.

BODE, of Berlin, has publilbcd the laft part of his 

 large Celeftial Atlas in twenty ihcets, which contains all the 

 old conftellations, with feveral new ones, and fome thoufands 

 of ftars, with which I furniflied him ; an immcnfe labour, of 

 which the aftronomers had need. This beautiful work may 

 be procured at the College de France. 



On the 27th of September the Helvetic republic adopted 

 the French meafures. This is the fir(l of the European ftates 

 which has been fenfible of the importance of this univerfal 

 meafure to the general good of civilized nations. 



Guglielmini, of Bologna, has made three new experiments 

 on the fall of bodies, to prove the rotation of the earth : he 

 has found the fame deviation from the fouth within a line, 

 though it is not given by theory ; but the deviation from the 

 welt he has found as it ought to be. Preparations are making 

 for obfervations of the fame kind at Hamburgh from the 

 tower of St. Michael, at the height of 326 feet. 



The obfcrvatory of Cadiz, during feveral years, has fur- 

 niflied us with a ferics of important r)bfervations; but for 

 fome time it has been neglected. General Mazzaredo has 

 caufed a new one to be built in the Ille-de-Leon, and he has 

 attached to it four aUronomers, officers in the navy — Rodrigo 

 Armofto, Maximo-Lariva Agucro, Julian Canela, and Jo- 

 feph Cuefla, who have refided there four years. For ten 

 VL-ars pad, a nautical almanac has been publiflied in Spain. 

 i hope navigation and aftronomy will be benefited bv it. The 

 telefcopc 25 feet in length, made by Dr. Herfchel for 

 Spain, will be fent off in the month of January ; and Du- 

 pout will go to Spain to mount it.
