JULY 6th, 1653 : ETEXINO. 



Lat. at 8A. 30m., 32 13' N.: Lon. 136<-' 34' E. 



Sun set 7A. 5m. 



Stronger and Diffuse Light at 8A. 30m. and 9h. 30m.

Clouds prevented any observations till 8 h 30 m . Afterwards, the view was interrupted by flying cirri ; but still I 

 was able to get reliable boundaries. 



The outlines of the paled sky are marked as before, by a dotted line a a. 



At 10 o'clock the Light was strongest about 94 Leonis Majoris, where it was equal to that of the Milky Way, in 

 the head of Scorpio, or about 10, 11, 14, and 15 Sagittas. 



[P. S., 1856. I am not able, in this reduced chart, to insert all of the dotted line. In my original chart, at Ion. 

 180 it reaches 49 30' lat. ; it terminates at 125 of Ion., in lat. 52.]
