NOTE II. 



Besides several other remarks, various details are here communicated with 

 respect to the size, brightness and general appearance of the nebulae, the positions 

 of their axes, etc., that are intended to form not unimportant additions to the sum- 

 mary descriptions in the preceding tables. 



In these notes, as is commonly tbe custom in descriptions of nebulae , I for 

 couveniauce's sake employ certain abbreviations and signs, wbich indeed in general 

 agree with those used by Sir John Herscmel and Lord Rosse, but the significa- 

 tions of which it is however necessary here to indicate.
