No. 187. 



JULY 24th, 1651 (23d was Sunday): MORNINO. 



Lat. at 3A.,25 39' N.: L'in. 121 37' E. 



Sun rose 54. 2fim. 

 Stronger and Diffuse Light at iA. 30m. and 3A. 15m. 



Moon in the morning since the 8th. Was on deck at 2'', and found the Zodiacal Light quite distinct ; hut on 

 account of flitting clouds, could not get boundaries till 2 h 15" 1 . (Sky all clouded over at 3 h , hut clear again at 3 1 ' 30'", 

 when I had a very good ohservation. The Stronger Light now, in the morning, is very hright . ; hut the Diffuse is 

 dim just the reverse of what we have in the evening. Once or t*vice I thought that there were pulsations in the 

 intensity of the Stronger Light ; hut Venus is now so bright at the lower end of the Light., that it is difficult to tell. 

 Dawn about 4 o'clock.
