which is situated in the very center of a globular nebulosity, 
it will evidently point out the high probability, or rather the 
certainty, that nebulous stars only differ from round nebulae 
containing a nucleus, in the order of condensation, which in 
the case of the nebulous stars, has been carried to a somewhat 
higher degree than in the nebulous nuclei. 
6 . Of Stars connected with extensive windings of nebulosity.* 
The nebulosity which has been shewn to be connected with 
stars may be fully proved to be of the same nature as the 
general mass of nebulous matter by the following instances. 
IV, 33. “ A star situated upon a ground of extremely faint 
‘‘ milky nebulosity diffused over this part of the heavens, has 
“ a milky chevelure surrounding it, which is brighter than 
“ the nebulosity of the ground ; but which loses itself imper- 
“ ceptibly in the extreme faintness of the general diffusion of 
“ the nebulous matter." See fig. g. 
The formation of these objects is extremely instructive, as 
it manifests the affinity between the matter of which stars are 
composed, and that of the most unshapen chaotic mass of ne 
bulosity. For the vanishing chevelure of a star being equally 
connected, on the one hand, with the generally diffused nebu- 
lous matter, and on the other with the star itself, round which 
it is in a state of gradual condensation ; this double union de- 
notes the mutual gravitation of the whole mass of nebulosity 
and the star towards each other ; and unless this proof can be 
invalidated, we must admit the fact of the growing condition 
of stars, that are in the situation which has been pointed out. 
This argument also adds greatly to the probability of stars
