SINGULAR CAVERX. 



A singular cavern has lately been discovered two kagucaf 

 from Nizza, in the district of Falcion. It has a narrow 

 cutrance, and the interior divisions, which have not yet 

 i)een sufficiently explored, contain natural temples sup- 

 ported by columns fo-.-med by crystallizations. Some of 

 these columns are so large that 400 persons cannot encom- 

 pass them. On account of the great reflection, very httic 

 light is required to illuminate this cavern, 



ASTRONOMY. 



The astronomers Delalande junior and Burckhardt observe 

 v.ith great assiduity the planet discovered by Dr. Olbers on 

 the 2Sth of March 1802. Its longitude on the 1st of July at 

 1 1'' 45' was 9 signs 7° 14' 25", and its latitude 46'^ 23' 18". 

 Eurckliardt has thence deduced its revolution to he 1682 

 days, or four years seven months and twelve days; which is 

 a day less than what was found some months ago, as may be 

 seen in my Blhliographie Astronomique ']ui\. published; but 

 at present there is scarcely an uncertainty of a few hours. He 

 is employed in calculating the derangements it must expe- 

 rience from the attraction of Jupiter, and which are very 

 complex J but he has presented to the Institute a learned 

 memoir which leads to this research.
