A clear and brilliant evening. Got observations at 8' 1 15 m , &c., as in the chart. At 9* the Stronger Light was dim 

 above 29 Virginia. At that time it possibly extended up to a. Librre, but I could nut be certain about it. At 9" 45 m , 

 both Diffuse and Stronger Light quite distinct, aud at 10" also ; though the Stronger Light had then dimmed very 

 much.
