This star was measured under the idea that it was an 
unobserved star. 
Our measures in the former paper are for the position of 
AB. 39 0 29' sf; of BC. io° 41' sj ; of AD. 67° 20' np ; 
1822.09 ; and for the distance, 
of A B. 6".862 ; of B C. 3". 24,3. 
The distances ascribed to A B disagree, it is true, more than 
a second, a very considerable quantity on so small a distance, 
it must be confessed. It is probable that the real distance is 
a mean between them, or 7".42.
