See fig. 6 . 
Here u’e have a list of fourteen objects, in which the pro- 
bability of a union between the nebulosities and the stars 
will gradually become more apparent. With regard to the 
first nine, the particularity of their construction is already 
very pointed : the conditions are that the nebulosity must be 
extended ; the direction of its extension must be exactly to- 
wards the star, and it must also be apparently just near enough 
to touch it; but that all this should happen cannot be probable; 
whereas a real contact of the objects, held together by mutual 
gravitation, will readily account for the whole appearance. 
In the two next objects there is already some indication of 
a union between the nebula and the star, for the roundness of 
the nebulosity appeared to be a little drawn out of its figure 
towards the star. 
But the last three instances, in which the whole mass of 
nebulous matter is pointedly directed to the stars, and in con- 
tact with them, can hardly leave any room for doubting a union 
between them. 
Now if we admit a contact, or union between these nebulae 
and the stars, it deserves to be remarked that stars, in the 
situation of these fourteen, cannot have been formed from 
their adjoining nebulosities ; for a gradual condensation of the 
nebulous matter would have been central ; whereas the stars 
are at the extremity of the nebulae. It is therefore reasonable 
to suppose that their conjunction must be owing to some
