266 Dr, Herschel*s Astronomical Observations 
Connoiss. 6 is “ A cluster of stars of various sizes contain- 
ing several lines that seem to be drawing to a centre like a 
“ forming cluster/^ 
VIII, 35 is “ A large cluster of stars considerably com- 
“ pressed and rich ; some of the stars are arranged in a long 
“ crooked line/* 
VIII, 44 is “ A very coarsely scattered cluster of large stars ; 
“ they form a cross and extend over a large space; not rich/* 
See fig. 13. The stars about the cluster belong to the milky 
way. 
VIII, 83 is “ A cluster of scattered stars above 15' in dia- 
“ meter; pretty rich and joining to the milky way, or a pro- 
‘‘ jecting part of it.** 
The 20 objects here referred to are not given as instances 
of the actual formation of clusters, which, being an effect that 
must undoubtedly require much time, cannot be visible ; but 
merely to draw our attention to a seemingly aggregating ar- 
rangement of the stars, which must render it probable that in 
regions where stars are very numerous, but unequally scat- 
tered, a clustering of them may arise from the preponderating 
attractions residing in different places. 
11. Of irregular Clusters, 
When clusters of stars are situated in very rich parts of the 
heavens, they are generally of an irregular form and very 
imperfectly collected ; those which are in, and very near the 
milky way, may indeed be looked upon as so many portions 
of the great mass drawn together by the action of a clustering 
power, of which they tend to prove the existence. 
I have divided the following 112 objects into two collections.
