Cloudy weather since last date till this evening, when the sky was quite clear, allowing me to have a good obser- 

 vation. I could not observe, this evening, that the Stronger Light changed to the left, as previously noted; but if 

 this is the fact, the Milky Way would make it diiHciilt to l>c observed. At S h 3fl m , the Light was still visible, but 

 was too dim to give outlines.
