The night is remarkably fine, and the stars are extremely steady ; still the mea- 
sures of this double star are so excessively difficult, that the observations of it, 
although made with every possible care, may be liable to error. To attempt to 
measure it, except under the most favourable circumstances, will always be useless. 
I had often looked attentively for this small star, both here and in England, fully 
persuaded from the authority of Mr. Struve* that it existed ; but till this evening, 
it does not appear from my Observatory Journal, that I have even once suspected 
that I saw it.

Night very favourable for delicate observations ; still the extreme faintness of 
the small star renders the measures open to suspicion.

♦ Mr. Struve’s catalogue contains the places of several stars called double by 
Piazzi ; in numerous instances however, I am satisfied that Piazzi’s instrument 
has deceived him.
