The first of them contains 8o clusters of which the size or 
figure has not been particularized.* 
VIII, 4 is “ A cluster of coarsely and irregularly scattered, 
“ pretty large stars, of nearly one size and colour."" See 
fig. 14. 
The stars of these clusters are in general very promiscu- 
ously scattered; they are however sufficiently drawn together 
to shew that they form separate groups ; and in many places 
a defalcation of the number of stars surrounding the clusters 
is already so far advanced as to indicate a tendency to future 
insulation. 
The second collection contains 32 irregular clusters that are 
from 2 to 30' in diameter.''^* 
VII, 4 is “ A cluster of large stars about 20 or 25' in dia- 
“ meter, considerably rich; it is of a coarsely circular figure."" 
The great number of clusters in these two collections is not 
only an indication that they owe their origin to a clustering 
power residing in the stars about their center; but the still 
remaining irregularity of their arrangement additionally proves 
that the action of the clustering power has not been exerted 
long enough to produce a more artificial construction. The
