44?8 Sir W. Herschel’s astronomical observations 
“ 1810, large 10 feet telescope. A globular cluster; its 
“ diameter is 2' 40V’ 
“ 1810, 40 feet telescope. A beautiful cluster of stars.” 
By the observation of the 7 feet telescope, the profundity of 
this cluster must be of the 243d order. 
Observations of the ^tfh of the connoissance. 
“ 1783, 1784, 7 feet telescope. With 100 and 120 it is a 
£< collection of very small stars; I see many of them.” 
“ * 799 , 1801, 10 feet telescope. Several of the stars are 
“ visible ; it is a very faint object.” 
“ 1784, 20 feet telescope. Some stars are visible in it; 
“ the edges are not resolvable.” 
“ 1805, 1810, large 10 feet telescope. With 108 it con- 
££ sists of extremely small stars, of an irregular figure ; a 
££ very faint object of nearly 12 minutes in diameter.” 
“ 17 99, 40 feet telescope. Very bright in the middle, but 
££ the brightness is confined to a very small part.” 
By the observation of the 7 feet telescope, the profundity 
of the nearest part of this cluster must be of the 243d order, 
but most probably a succession of more distant stars was 
seen in the larger telescopes.

“ 1 799 > 7 feet finder. It is but just visible.” 
“ 1799, 7 f eet telescope. There is not the least appearance 
cc of its consisting of stars, but it resembles other clusters of 
<£ this kind, when they are seen with low space-penetrating 
ts and magnifying powers.”
