IV. 49 is “ A pretty bright stellar nebula, like a star with a 
small bur all around.” 
The other two are of the same nature.* 
IV. 15 is “ A stellar nebula, or rather like a faint star with 
“ a small chevelure and two burs.” 
The other two are nearly of the same description.

It may have been remarked, that many stellar nebulae of my 
catalogues have the memorandum added to their descriptions 
that they were confirmed with a higher magnifying power, 
and that this was sometimes attended with difficulty, ana 
sometimes could not be successively done. 
A collection of thirty-four nebulae that come under this 
description is as follows

which shewed it “ pretty bright, but hardly to be distinguished 
from a star.” 
III. 29 is “ A very faint extremely small stellar nebula or

It must be noticed, that in these nebulae the doubt which 
was entertained did not relate to the existence of the objects, 
but merely to their nature; and when the suspected nebula 
was so faint that even its existence was doubtful, a higher
