446 Sir W. Herschei/s astronomical observations 
Observations of the 6<2.d of the connoissance. 
“ 1783, 10 feet telescope. With 250, a strong suspicion, 
“ amounting almost to a certainty, of its consisting of stars/’ 
“ 1785, 1786, 20 feet telescope. Extremely bright, round, 
“ very gradually brighter in the middle, about 4 or 5 minutes 
“ in diameter . 240 with strong attention showed the stars 
“ of it. The cluster is a miniature of the 3d of the con- 
“ noissance.” 
By the 20 feet telescope, which at the time of these obser- 
vations was of the Newtonian construction, the profundity 
of this cluster is of the 734th order. It is in the preceding 
branch of the milky way. 
Observations of the 6yth of the connoissance. 
“ *783, 7 feet telescope. A cluster of stars/’ 
** 1809, 10 feet telescope. A cluster of very small stars.” 
“ 1784, 20 feet telescope. A most beautiful cluster of 
“ stars ; not less than 200 in view.” 
By estimation, the profundity of this cluster may be of the 
144th order. 
Observations of the 68th of the connoissance. 
“ 1786, 1789, 1790, 20 feet telescope. A cluster of very 
“ compressed small stars, about 3 minutes broad and 4 
“ minutes long. The stars are so compressed, that most of 
“ them are blended together.” 
Probably the stars of this cluster might be perceived by a 
10 feet telescope, so that its profundity may be of the 344th 
order.
