mass, or, what is more probable in the compound energy of 
the stars about the centre. The lines of the bright stars, al- 
though by a drawing made at the time of observation, one of 
them seems to pass through the cluster, are probably not 
connected with it. 
14. Of diff-'erently compressed Clusters of Stars. 
I have hitherto only considered the arrangement of stars 
in clusters with a view to point out that they are drawn to- 
gether by a clustering power, in the same manner as the ne- 
bulous matter has, in my former paper, been proved to be 
condensed by the gravitating principle; but in the 41 clusters 
of the following two collections we shall see that it is one and 
the same power uniformly exerted whicii first condenses ne- 
bulous matter into stars, and afterwards draws them together 
into clusters, and which by a continuance of its action gradu- 
ally increases the compression of the stars that form the 
clusters. 
The first collection contains 33 clusters, the stars of which 
are considerably compressed.* 
VII, 12 is “ beautiful cluster of pretty compressed stars, 
“ near half a degree in diameter. It is considerably rich, and 
“ most of the stars are of the same size."" 
The moderate compression of the stars in the clusters of 
this order renders them fine objects for good telescopes. 
The second coilectijii contains 8 clusters in which the
