Clouds since last date, except Sunday evening. This morning perfectly clear, and sky very brilliant. Had an 

 eastern observation half an hour before midnight : the Zodiacal Light fully distinguishable: though dim, still quite 

 decided at that hour. At 4'' the Stronger Light was much the brightest from the horizon up to the zigzag : the upper 

 terminations of Stronger and Diffuse Light could not be fully made out, and I have marked the places with dots, where 

 by inference we may believe them to terminate. After 4'', I watched carefully to see whether there were pulsations 

 or not ; was pretty certain sometimes that there were ; at others, was doubtful. Took record of some things that 

 appeared to be changes in intensity of light, but it is all so uncertain, that I am scarcely willing to offer the record. 

 Thus : 4" 22"', very dim ; 



* * bright ; 



4" 25"', dim ; 



4" 27 t m , bright.
