larly where the centaur Eurylhion endeavours to carry 

 away Hippodamia, and is prevented by Theseus; also the 

 two centaurs, who are seen forcibly carrying away the vir- 

 . gin, and the youth her lover. The latter subject is more 

 difficult of divination ; and the suggestion of its being the 

 abovementioned, arises only from the persons of Antiope 

 and Theseus being very conspicuous in the groiipe. The 

 whole formed the fnze of the interior of the Cella, which 

 was of the Ionic order, and the relievo is even higher than 

 that of the temple of Theseus. The opinion of its being 

 the work of Fhidias, independently of the style of sculp- 

 ture, is also strengthened by the circumstance of the temple 

 being built by (ciinus, who generally gave the preference to 

 the above sculptor. 



The Members of the Turin Academy have offered prizes 

 of 600 francs for each of the best memoirs on the follow- 

 ing subjects : 



1. *' An account of the origin, appearance or formation 

 of aerolites, either ancient or modern, but founded upon ri- 

 gorous principles, and upon conclusions from incontro- 

 vertible facts, and which will consequently agree with the 

 various atmospherical phsenomena which precede, accom- 

 pany, and follow the fall of an aerolite." 



2. ^' Determine the epoch of the perihelion return of the 

 comet of 1759, generally knovi^n by the name of Haller's' 

 Comet, taking a minute account of the perturbations." 



The Academy requires the reduction into numbers of the 

 analytical forms. 



The memoirs are to be tran$mitted to Turin on or before 

 the 1st August 1813. 



THE NEW COMET. 



Extract from a Paper read to the French Institutey 

 Jug. 31, 1812. hy M. Aicolet. 



*' A new comet was discovered on the 20th of .Tiily, by 

 M. Pons, at Marseilles, and on the 1st of August follow- 

 ing by M. Bouvard at Paris. M. Boijyard and myself 

 calculated that the comet would come nearest in contact 

 with the sun on the 15th of September, 92'. 27". m«an 

 time, reckoned from the midnight of Paris, 



" The distance from the earth to the sun being taken as 

 unity, that of the comet in its perihelion will be 0,77,835.
