another planet. It appeared like a star of the tenth

 name Bellona ; the symbol proposed being a whip and

 Chacornac, assistant observer at the observatory of Paris. 

 The same impression of the Times contained two inde- 

 pendent communications from Mr. Hind of London, and 

 Mr. Johnson of Oxford, each containing the announce-

 at Marseilles, M. Chacornac noted a star of the tenth 

 magnitude, which is now wanting in that place, and 

 which is shown to have been the body first recognized 

 as a planet by Mr. Marth. 



On the 22d of July, 1854, the thirtieth asteroid was 

 discovered by Mr. Hind at Mr. Bishop's observatory in 

 Regent's Park, London. It appeared like a star between
