48 Mr, South's observations of the apparent distances 

 T No. CCCCXLI. continued. 



Measures of A C.

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. 



Passy; December 29, 1824 ; Seven-feet Equatorial. 



4th and 20th magnitudes. 



Position = 72*5' sp \ 3 Obs. | DifF. = i*» 38'. Excessively difficult. 



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.

Night very fine. 



Measures of A D.

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.
