meeting of the Royal Ast. Soc., March 10th, 1865, Mr. Huggins remarked 
that “* the recent examination of the Great Nebula i in Orion shows that 
this large and wonderful object belongs to the class of gaseous bodies, 
The light from this nebula resolves itself. under the refractive power of the 
prism into the same three —— lines. With a narrow atten they ye

' Since the pera apenas bi lataa of the enormous distances of the 
nebula has no longer any ation to rest upon, in respect of the 
nebule which give pe pa trum, it is much to be desired that 
motion should be sought fer in such of them as are suitable for 
this purpose. 
'€ gaseous matter of these objects represented the ‘ nebulous 
fluid” out Ms which, according to the hypothesis of Sir Wm. Herschel,

groups of bright lines were as numerous as the dark lines due to absorp-
