78 HISTORY OF ASTRONOMY. 



On the same evening with the preceding, and nearly 

 at the same hour, the thirty-seventh asteroid was discov- 

 ered by Dr. Luther at Bilk. It appeared like a star of 

 the tenth magnitude, and on the following day the dis- 

 covery was communicated by telegraph to the editor of 

 the Nachrichten. On the 7th it was seen both at Altona 

 and Hamburg. This planet has received the name of 

 Fides. 



On the evening of the 12th of January, 1856, M. Cha- 

 cornaCj at the Paris observatory, discovered a new planet 

 equal in brightness to a star of the ninth or tenth magni- 

 tude. This planet has received the name of Leda. 



On the 8th of February, 1856, M. Chacornac, of the 

 Paris observatory, discovered a new planet, being the 

 thirty-ninth asteroid, and equal to a star of the eighth or 

 ninth magnitude. This planet has received the name of 

 Laetitia. 



On the 31st of March, 1856, a new planet, being the for- 

 tieth asteroid, was discovered at Paris by M. Hermann 

 Goldschmidt ; and on the 6th of April it was observed 

 both at Altona and Hamburg. It appeared like a star of 

 the ninth or tenth magnitude, and has been named Har- 

 monia. 



* On reviewing the preceding sketch, we find that Mr. 

 Hind, of London, has been the first discoverer of ten as- 

 teroids; M. de Gasparis of seven; Mr. Luther of five; 

 M. Chacornac of five; M. Goldschmidt of four; while 

 Olbers and Hencke, have each discovered two. "We also 

 see that, in several instances, the same asteroid has been 

 independently discovered by more than one astronomer.
