 that the stars are scarcely perceptible.

Night very foggy ; stars ill defined and unsteady. 



A continuation of bad weather from this date till the 22nd 

 instant, v^^hen the observatory at Passy was demolished, ren- 

 dered further observations of this star impracticable.

Position &* 55' nf{4>^ Obs.); Distance 9".904 (so Obs.); 



Epoch 1825.78. 



In 1821.9 the angle was measured at ?** 9' nf. The 

 motion therefore in 3.9 years appears only to have been 

 o'' 14', direct, whereas computing on the annual motion 

 + o°.5i33 it should be 2° o'. The observation of 1821 is 

 a mean of not more than 7 single measures. It is possible 

 therefore that it may be somewhat erroneous, though proba- 

 bly not to the whole extent ( 1° 46') which this discordance 

 would require ; yet a trifling error in the present measure or 

 in the angular velocity would reconcile all. Meanwhile the 

 main point, the direction of the motion, agreeing, may be 

 regarded as confirming the result already arrived at. (H.)
