I think it is very evident the erroneous result will be that 

 given in the published memoir; supposing the v^rong 10th 

 degree to have been taken, the mean angle as read off, 

 instead of being — 44° 33' would be — 54° ss' = + 35° 2/, 

 a difference from the angle here determined easily enough to 

 be admitted, when the closeness of the stars is considered. 



Passy; August 9, 1825 ; Seven-feet Equatorial, 



8th and 8J magnitudes. 

 Position = 32° 35' sf \ 6 Obs. [ Diff. = 2° 17'. Rather difficult. 



Observed with 413 when 20 minutes west of the meridian ; 

 stars very unsteady, so much so that measures of distance are 

 impracticable. Set the position wire to — 45°, and it is so 

 intolerably offensive to the eye that it never can have passed 

 for a measure ; the stars stride across the wire. There can 

 be no doubt therefore, that the micrometer was in the obser- 

 vations of September 1823, read o^ incorrectly,

Observed when on the meridian with 327, the highest power which I can use 

 to night with advantage.

Observed on the meridian with 327, the highest power which the unsteadiness of 

 the stars will allow me advantageously to employ. Observations of distance are 

 impracticable.
