Sky very favorable for observations, and, at I 7 h 30 m , I was able to get boundaries, which may be considered fully 

 reliable. At 8" the sky was still favorable, and the Zodiacal Light was still bright ; but, soon after this, the Light 

 began to grow dim ; and, at 8 h 30 m , it had dimmed so much, that it was with some difficulty I was able to get bound- 

 aries. Those given in the chart, however, I believe may be relied on.
