Dr. Her sc hex/ s Astronomical Observations 
12. Of the remarkable Situation of Nebulce. 
The number of compound nebulae that have been noticed 
in the foregoing three articles being so considerable,- it will 
follow, that if they owe their origin to the breaking up of some 
former extensive nebulosities of the same nature with those 
which have been shewn to exist at present, we might expect 
that the number of separate nebulae should far exceed the 
former, and that moreover these scattered nebulae should be 
found not only in great abundance, but also in proximity or 
continuity with each other, according to the different extents 
and situations of the former diffusions of such nebulous matter. 
Now this is exactly what by observation, we find to be the 
state of the heavens. 
In the following seven assortments we have not less than 
4,24, nebulae ; some of them of unascertained size, figure, or 
condensation ; and the rest with only the first of these three 
essential features recorded. 
The reason for not having a more circumstantial account of 
such a number of objects, is that they crowded upon me at the 
time of sweeping in such quick succession, that of sixty-one 
I could but just secure the place in the heavens, and of the 
remaining three hundred and sixty-three, I had only time to 
add the relative size.*
