s8o Dr. Herschel's Astronomical Observations 
not be able to ascertain exactly into what class we ought to 
place them ; but as it frequently happened that I saw three 
objects in succession, the first of which was a brilliant globular 
cluster of stars, the second a miniature of the former of which 
the stars could but just be perceived, and the third in every 
respect a similar miniature of the second as the second was 
of the first, but in which the stars, "though suspected, were no 
longer to be distinguished, I called them second miniature 
globular clusters. The following collection contains five of 
them.* 
1 , 45 is “ A bright round nebula, much brighter in the middle, 
“ but the brightness decreasing very gradually. It is a perfect 
“ miniature of VI, is, which is itself a miniature cluster of the 
“ 19th of the Connoiss.*" 
I, 48 is “ A miniature of the 9th of the Connoiss."' (which 
is itself a miniature of the 53d) “ I suppose if I had looked 
“ long enough, I might have perceived some of the stars which 
“ compose it."^ 
1 , 147 is “ A miniature of the 6sd of the Connoiss. which is 
“ a miniature of the 3d.*" 
I, 51 and Connoiss. 6 q are second miniatures of the 53d.

In the ibth article I have given a description of the most 
magnificently constructed sidereal systems; and very little 
doubt can be entertained but that the objects of the 17th and 
18th articles are of the same nature, and are only less beautiful
