Sir W. Herschel’s astronomical observations 
Observations of the 53d of the connoissance. 
■ “1813, 7 feet finder. It appears like a very small 
“ haziness/’ 
“ 1783, 7 feet telescope. With 460 the object is ex- 
“ tremely faint. 1813, with 118 it is easily resolvable, and 
“ some of the stars may be seen.” 
“ 1783, 10 feet telescope. With 250,1 perceive 4 or 5 
“ places that seem to consist of very small stars.” 
“ 1784, 1786, 20 feet telescope. A globular cluster of 
“ very compressed stars.” 
From the observation of the 7 feet telescope, it appears 
that the profundity of this cluster is of the 243d order. 
Observations of the 55th of the connoissance. 
“ 1783, small 20 feet telescope. With 250 fairly resolved 
“ into stars ; I can count a great many of them, while others 
“ are too close to be distinguished separately/’ 
“ 1784, 1785, 20 feet telescope. A rich cluster of very 
“ compressed stars, irregularly round, about 8 minutes 
“ long.” 
By the observation of the small 20 feet telescope, which 
could reach stars 38.99 times as far as the eye, the profundity 
of this cluster cannot be much less than of the 467th order : 
I have taken it to be of the 400th. 
Observations of the 56th of the connoissance. 
“ 1783, 7 feet telescope. A strong suspicion of its being 
“ stars.” 
“ *783? 1 799> 10 feet telescope. 220 will not resolve it;
