of them ; which renders it probable that our best instruments 
will not reach so far into the profundity of space, as to see 
more distant diffusions of it. In No. 44 of the table, we have 
an instance of faint milky nebulosity, which, though pretty 
bright in some places, was completely lost from faintness in 
others ; and No. 46 confirms the same remark. It has also 
been already mentioned in the first article, that the nebulosity 
in V. 14 was brighter in three or four places than in the rest. 
The stars also of the milky way which were scattered over 
it, and were generally very small, appeared with a brilliancy 
that will admit of no comparison with the dimness of the 
brightest nebulosity. In consequence of this, we may already 
surmise that the range of the visibility of the nebulous matter 
is confined to very moderate limits. 
3. Of Nebulosities joined to Nebulae. 
The nature of diffused nebulosity is such that we often see 
it joined to real nebulae; for instances of this kind we have 
the fourteen following objects.* 
The account of the three first nebulae being shortened in 
the catalogue, I give it here more at length. 
No. 81 in the first class is “ A considerable bright and large 
“ nebula. Its nebulosity is of the milky kind, and a small 
“ part of it is considerably brighter than the rest. The great- 
“ est extent of the milkiness is preceding the bright part, and 
** the termination of it is imperceptible.” To No. 207 should 
be added “ It seems to join to imperceptible nebulosity on the 
“south preceding side;” and to No. 214, “It terminates
