ZONE OF PLANETS BETWEEN MARS AND JUPITER. 71 



discovered another small planet near the bright star 

 Kegulus. It appeared like a small star of the tenth or 

 eleventh magnitude, and* has received the name of 

 Psyche. Mr. Hind, of London, narrowly missed the 

 honor of being the first discoverer of this body. On 

 the 29th of January preceding, he entered upon his chart 

 a star of the eleventh magnitude in the place where, ac- 

 cording to subsequent computations, this planet ought to 

 have been. The chart was immediately sent to the en- 

 graver, and not returned until March 18; but on the

 was missing. He immediately commenced a search for 

 the planet, and actually recorded it again on the 20th as 

 a fixed star, but moonlight and unfavorable weather 

 prevented him from establishing its planetary nature 

 before he received the announcement of Dr. Grasparis' 

 discovery. 



On the 17th of April, 1852, another planet was dis- 

 covered near Flora by Mr. E. Luther, at the observatory 

 at Bilk, near Diisseldorf. Professor Argelander, of Bonn, 

 proposed for this planet the name of Thetis, which name 

 was accepted by the discoverer, and has been adopted by 

 astronomers. 



On the 25th of June, 1852, Mr. Hind, at London, dis- 

 covered another planet, having the appearance of a star 

 of the ninth magnitude, and of a yellowish light. Mr. 

 Airy, the astronomer royal, having been requested by 

 Mr. Bishop to select a name for this planet, proposed to 

 call it Melpomene. It is the nearest of the group of
