value of the micrometer in seconds, rigorous examination 

 has satisfied me that it is precisely the same with that of the 

 micrometer formerly employed. The observations of this 

 date, and of all subsequent to it, will be made by means of 

 this micrometer.

Observed with 413, when a few minutes west of the meridian; the angles I con- 

 sider very good j but the distances are perhaps a little inaccurate : the stars are 

 well defined, but are very unsteady.

 Position = 32° 18' n/ 1 7 Obs. | Diff. = 6° 2'. Difficult. 

 I cannot procure any measures of distance, the extreme unsteadiness of the stars 

 rendering it impossible. Observed with 413. Stars tolerably well defined, and on 

 the meridian at the time of observation.

Diff. 



Observed with 413, a few minutes east of the meridian; stars unsteady, but at 



times well defined. 



Passy ; April 8, 1825 ; Seven-feet Equatorial. 



7th and 8th magnitudes. 

 Position = 32° 4' w/ 1 7 Obs. | Diff. = 7° 28'. Difiicult. 

 Observed on the meridian with 413, but the stars are so unsteady, that measures of 



distance are impracticable. 



Passy ; April 14, 1825 ; Seven-feet Equatorial. 



7th and 8th magnitudes. 

 Position = 32° o' nf\ 7 Obs. | Diff. = 4° 7'. Very difficult. 

 Observed with 41 3, with which power no measures of distance can be procured, 

 owing to the extreme unsteadiness of the stars. I therefore applied 327, and 

 obtained as results.
