planet, requested Prot. von Littrow, Director of the Vienna Observatory, 
to give the planet a name. Prof. von Littrow chose the name Eipis, 
in allusion to the political condition of Europe at the time of its discov- 
ery. is name was immediately accepted by the German astronomers. 
At length in January, 1862, Prof. LeVerrier announced that he no longer 
refused to allow Mr. Chacornac to select a name for this planet. Mr. 
Chacornac then requested Mr. Hind to assign a name, and Mr. Hind 
selected the name Olympia. This name has been accepted by the

his work in spite of all his precautions. 
The nebula in question was situated in right ascension 4h 13m 54‘6sec, 
and north declination 19° 11/37”, for the beginning of 1862. It was 
therefore about a degree and a half from the star Epsilon in Taurus, 
in the group commonly known as “the Hyades.” Its diameter wae
