Borealis. He describes the star as “very brilliant, of about the 
2d magnitude.” Also Mr. Baxendell of Manchester wrote to 
one of t us, giving the observations which follow of the new star, 
as seen by him on the night of the 15th instant: 
“A new star has suddenly burst forth in Corona. It is some- 
what less than a degree distant from ¢ of that constellation in a 
southeasterly direction, and last night was fully equal in bril- 
liancy to J Serpen tis or » Herculis, both stars of about the 3d 
magnitude.’ 
Last night, May 16th, we observed: this remarkable object. 
e star appeared to us considerably below the 3d magnitude, 
but brighter than ¢ Coronz. In the telescope it was surrounde 
with a faint nebulous haze, extending to a considerable distance, 
really existed about the star. When the spectroscope was 
placed on the telescope, the light of this new star formed a spec- 
trum unlike that of any celestial body which we have hitherto 
examined. The light of the star is compound, and has eman- 
ated from two different sources. Hach light forms itso own aa 
formed was emitted by matter in the state of luminous gas.’

accuracy in the annexed diagram.
