Night very clondy : these observations gotten by availing myself of the rapid 
motion of the clouds, which now and then presents the stars to view ; when visible 
they are unusually brilliant, and pass through the field as steadily as possible ; to 
obtain these measures I have not quitted the observing chair during the last hour, 
nor do I deem the time ill-spent : except under very unusual circumstances, no ob- 
servations of this pair of stars can reasonably be expected with this instrument.

Measures of distance impracticable ; and the night is become so unfavourable, 
that more observations of position cannot be gotten : yet measures of A B and A D 
might be procured with facility.

difficult. 
A B are more easily observed than A D, and A D than A C ; but all present con- 
siderable difficulties, and measures of them with this instrument will never be 
procured, except under the most favourable circumstances.
