for ascertaining the distances of clusters of stars, &c. 433 
Observation of the 12th cluster in the with class. 
“ 1784, 20 feet telescope. This cluster of stars is another 
“ miniature of the 19th of the connoissance, but rather coarser 
“ than my 11th cluster.” 
The profundity of the 19th of the connoissance being of the 
344th order, this cluster, as rather a coarse miniature of it, 
may be of the 466th order ; it is in the preceding branch of 
the milky way. 
Observations of the 1 yth cluster in the vith class . 
“ 1784, 1785, 20 feet telescope. A very rich cluster of 
“ very compressed and extremely small stars ; 4 or 5 
“ minutes in diameter.” 
This cluster is probably of a profundity of about the 600th 
order. It is in the preceding branch of the milky way. 
Observations of the 20 th cluster in the with class. 
“ 1785, 1786, 20 feet telescope. Considerably bright, 
“ irregularly round, 8 or 9 minutes in diameter ; a great 
“ many of the stars are visible, so that there can remain no 
" doubt of its being a cluster of the most minute stars 
“ imaginable/' 
The profundity of this cluster cannot be less than of the 
734th order. It is near the south pole of the milky way. 
Observation of the 26th cluster in the with class. 
“ 1786, 20 feet telescope. A very faint cluster of very 
“ compressed extremely small stars ; near 4 minutes in 
“ diameter.” 
The 20 feet telescope being of the construction of the
