86 . . THE NEBULA IN ANDROMEDA. 



A.R. 1850. Dec. 1850. Remarks, 



h. m. 8. n I 



12 34 24 +40 26 The nucleus. The light shades ofl" soonest on the fol- 



lowing side. 



13 35 00 40 36 The light is here broken up and unequal ; with numer- 



ous stars. The canals in this parallel begin to incline 

 towards the following side. 



14 32 00 40 36 Apparent continuation of h 44 in the south-following 



■direction towards the great nebula. 



15 36 40 40 36 A dark opening in the surrounding nebulosity. In and 



north of this parallel, the light is distributed with less 

 regularity than heretofore ; and the outer canal is fre. 

 quently interrupted. 



16 35 40 40 50 The inner canal is not to be traced with certainty be- 



yond this point. 



17 34 36 40 53 Stars very numerous. The light shades off more grad- 



ually on the side following the axis than it does 

 nearer the nucleus. 



18 35 50 40 57 A ridge of light, or of stars, parallel to the axis, gives 



the impression of a continuation of the inner canal. 

 Many small stars. 



19 35 11 41 .03 Light in decided bright knots, with dark openings, as in 



4 and 5. Great numbers of stars. This is the posi- 

 tion of h 45 ; there is no uncertainty with regard to 

 its being a part of the great nebula. 



20 38 12 41 20 Northern extremity of the axis.
