45° 'Sir W. Herschei/s astronomical observations 
“ 1 799, io feet telescope. 300 shows the stars of it with 
44 difficulty.” 
“ 1784, 20 feet telescope. A beautiful cluster of stars, 
44 nearly 3 minutes in diameter.” 
“ 1806, large 10 feet telescope. A globular cluster, the 
44 stars of which are extremely compressed in the middle ; 
44 with 171 and 220 the diameter is 2' 50'', but the lowness of 
44 the situation probably prevents my seeing the whole of its 
44 extent.” 
By the observation of the 1 o feet telescope the profundity 
of the cluster is of the 344th order. 
Observations of the 80 th of the connoissance. 
44 1784, 1786, 20 feet telescope. A globular cluster of 
“ extremely minute and very compressed stars of about 3 or 
44 4 minutes in diameter ; very gradually much brighter in 
“ the middle ; towards the circumference the stars are 
44 distinctly to be seen, and are the smallest imaginable.” 
The profundity of this cluster is probably not much less 
than of the 734th order. 
Observations of the gzd of the connoissance. 
44 1799, 7 feet finder. It may just be distinguished ; it is 
44 but very little larger than a star.” 
44 1783, 2 feet sweeper. With 15 it appears like a clouded 
44 star.” 
44 1783, 7 feet telescope. With 227 resolved into very 
44 small stars ; with 460 1 can count many of them.” 
44 1799, 10 feet telescope. With 240 the stars are much 
44 condensed in the centre.”
