4 1 8 OBSERVATIONS ON THE ZODIACAL LIGHT, 



No. 209. 



AUGUST 29th, 1834: MORNING. 



Lat.22 18' N. : Lon. 114 10' E. 



Sim rose at ah. 4"m. 



Stronger and Diffuse Light at 2 and 4 o'clock. 

 Sim's Ion. 105 44'. 



Sky in the evening dull: towards morning, very clear and bright. Got observations at 2 and 4 o'clock. The 

 upper termination of the Diffuse Light is very uncertain ; and I am guided, in drawing it, chiefly by the convergence 

 of the lines as seen lower down. Its track (i. e., of the Diffuse Light) across the Milky Way is now evident. I 

 looked to see whether there might be pulsations ; but if there are any, the Milky Way, crossing the zodiacal path 

 below, would make it difficult to detect them.
