1814 104 2G9 XIII. Of clusters of stars of a peculiar description. 



Six such objects named : One in the milky way, three near 

 it, two at a distance from it. 



271 XIV. Of differently compressed clusters of stars. 



I have hitherto only considered the arrangement of stars 

 in clusters with a view to point out whether they are 

 drawn together by a clustering power in the same man- 

 ner as the nebulous matter has been proved to be con- 

 densed by a gravitating principle ; but in the forty-one 

 clusters of the following two collections we shall see that 

 it is one and the same power uniformly exerted which 

 first condensed nebulous matter into stars and afterwards 

 draws them together into clusters, and which by a contin- 

 uance of its action, gradually increases the compression 

 of the stars which form the clusters. The first collection 

 has thirty-three considerably compressed clusters, seven- 

 teen in the milky way, fifteen near it, and one at a 

 distance. The second collection contains eight clusters, 

 highly compressed, five in the milky way, two near it, 

 and one at a distance. 



272 XV. Of the gradual concentration and itisulation of clusters 



of stars. 

 The existence of a clustering power is nowhere so visibly 

 pointed out as in the thirty-nine clusters given in the 

 following collection : Twenty-one of these lire in the 

 milky way, seven near it, and eleven at a distance. 



273 XVI. Of globular clusters of stars. 



Fourteen such objects noted : One in the milky way, four 

 near it, and nine at a distance from it.

 19; M. 53.] 



278 XVII. Of more dis'ant globular clusters of stars. 



The following eleven objects are so like those of the fore- 

 going collection that I have called them miniatures of 

 the former. Five of these are in the milky way, one 

 near it, and five at a distance. Detailed descriptions 

 given. 



279 I have supposed the clusters of this class to be at a greater 



distance from us than those of the preceding collection, 

 because the stars of which they are composed are more 

 minute than those of the clusters of which I have called 

 them miniatures ; their compression is also closer, and 

 the size of the whole is much contracted, all of which
