358 OBSERVATIONS ON THE ZODIACAL LIGH7. 



No. 179. 



JULY ]3th, 1854: ETENIVS. 



Lat 2.5 9' N : Lon. 121 40' E. 



Sun ser G/i. 48m. 

 Stronger and Diffuse Lii ht at 9A. 



Moon and thin clouds since my last, both morning and evening. The early part of this evening cloudy; but at 9 s 

 I was surprised to fiud the sky clear and remarkably brilliant very good for observations. Had a careful one at 9 h , 

 particularly so as respects the angle which the Zodiacal Light seems now to make with the ecliptic. For result, see 

 the chart. The lower end of the Stronger Light, as high as about a a, is bright; above this, it goes tapering off, so 

 as at last to be very dim. Still, as I made repeated trials of observation, and always with the same result, I thinll 

 the outlines given may be relied on. Soon after 'J' 1 , clouds arose and prevented further observations.
