ASTRONOMY AND METEOROLOGY.

his memory with great fidelity their general form and arrangements, 

 was amusing himself on the night of the 15th of November in examin- 

 ing with a spy-glass the constellation Aries. His attention was attract- 

 ed by an unusual small point, which moved slowly in a direct sense. 

 Its motion determined its planetary character, but the twenty asteroids 

 previously discovered rendered its originality doubtful. M. Gold- 

 schmit, however, taking the elliptic elements of the orbits of all the 

 small planets, calculated their respective positions, and ascertained 

 none were then in the constellation Aries. He reported the facts at the 

 observatory, and the astronomers confirmed his discovery. This planet 

 has the appearance of a star of the eighth or ninth magnitude, and at 

 the suggestion of Arago has received the name Lutetia, in honor of the 

 city of Paris. The usual prize has been awarded to M. Goldschmit 

 by the French Academy. 



On the 16th of November, Mr. Hind discovered the twenty-second 

 asteroid. Its inclination to the ecliptic is 14 20' 13" ; mean distance 

 from the sun 2.9412, eccentricity 0.10458 ; period of revolution 1842 

 days, or little more than five years. This planet has received the 

 name Calliope. 



The number of asteroids, therefore, known at present to exist 

 between Mars and Jupiter, is twenty-two. Nearly all these minute 

 bodies have heen detected by means of the Berlin Star Charts ; the 

 largest of their number, Vesta, never appears, even when nearest the 

 earth, brighter than a star of the sixth magnitude ; while Metis, the 

 smallest, is never more brilliant than one of the eleventh. Their 

 names, date of discovery, &c., are as follows :
