These observations, with another made at Marseilles, on the first day, at 

 9^ 55*" 38^ equal time, when the longitude of the comet was found in ^ 

 23° 29' 46'', and its north latitude 3l' 20', enabled him to compute the elements 

 of its orbit. Its motion is direct. The ascending node is in S| 1 9° 42' O", and 

 the place of the perihelion in y 26^41' 22''. The inclination of the orbit is 

 80° 5 l' 30', and the distance of the perihelion ,%WW of the radius of the 

 orbit of the earth. The comet passed the perihelion Nov. 25, 17 59, at 

 20^ 55"^, mean time at Paris. 



LVII. Extracts of some Letters from Signer Abhate de Venuti, F. R. S. to 

 J. Nixon, A. A/., F. R. S. relating to several Antiquities in Italy, p. 636. 



Sig. V. had bought a relievo, which in his opinion was very singular. It 

 was of marble, 2 palms wide, and 1 high, and represented in a neat taste, a 

 faun, with a tail and wings ; which latter circumstance had never occurred to 

 his observation before. He seemed to be dancing, and his dog at his feet in the 

 same attitude. Near him was a tree, to which was tied a very elegant open 

 chariot (thensa,) and beneath it there appeared a table, such as were used in 

 entertainments, with a goblet on it, charged with relievo in embossed work. 



He also met with a cornelian, on which was engraved a man cloathed with a 

 pallium, and sitting on a chair : before him there appeared a lighted furnace, and 

 on it a vessel of glass, or earthen ware. The artist himself held in his hand a 

 pair of iron pincers, with handles, to take off the vessel from the fire, without 

 burning himself. 



Remarks on the preceding Extracts, By John Nixon, A.M., F.R.S. p. 639. 

 These throw no light on the above antiquities.
