cumstances we may therefore conclude that this cluster has 
been long under the influence of the clustering power. See

Connoiss. 68 is “ A beautiful cluster of stars, extremely rich, 
and so compressed that most of the stars are blended toge- 
ther ; it is near 3^ broad and about 4' long, but chiefly round, 
“ and there are very few scattered stars about.'" 
This oval cluster is also approaching to the globular form, 
and the central compression is carried to a high degree. The 
insulation is likewise so far advanced that it admits of an. ac- 
curate description of the contour. 
The clusters of this class are beautiful, but can hardly be 
seen to any advantage without a 20 feet telescope. 
16. Of globular Clusters of Stars. 
The objects of this collection are of a sufficient brightness 
to be seen with any good common telescope, in which they 
appear like telescopic comets, or bright nebulee, and under 
this disguise, we owe their discovery to many eminent astro- 
nomers ; but in order to ascertain their most beautiful and 
artificial construction, the application of high powers, not only 
of penetrating into space but also of magnifying are absolutely 
necessary ; and as they are generally but little known and 
are undoubtedly the most interesting objects in the heavens, I 
shall describe several of them, by selecting from a series of 
observations of 34 years some that were made with each of 
my instruments, that it may be a direction for those who wish 
to view them to know what they may expect to see with such 
telescopes as happen to be in their possession.*
