The night excellent for observations. The twilight is beginning to be long ; got my first observation at 7 h 45 a . 

 At I 7 h 55 m , and thence onward, the Stronger Light was much the strongest (like the effulgence often noticed in the 

 morning) within the zigzag a a; this was still so at 8' 1 45 m . At &'' 4 m the Light had dimmed, but was still well 

 marked in the sky, and gave reliable boundaries.
