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° 29' sf; of BC. 10° 41' sf ; of AD. 67° 20' np ; 

 1822.09 ; and for the distance, 



of A B. 6".862 ; of B C. 3".243. 



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.
