We have much clomly weather now, owing to the change oi' monsoons. Hail an observation on the evening of the 

 llth, hut the Zodiacal Liglit was so faint that I have not thought it Lest to give a distinct chart for it. The moon 

 also interfered that evening till at S' 1 10 ra , when it got into a fog-Lank near the horizon; at that hour, though the 

 Zodiacal Light was dim, I could see that the houndaries of the stronger portion were, as on the preceding evenings; 

 the left-hand boundary being at AldeLaran, and the right, grazing the southern portion of the Pleiades. At 8 h 30 m 

 the Light could scarcely Le made out at all; and I could not, at any time, get the boundaries of the Diffuse Light. 



From the llth till this evening, cloudy weather. To-night I was continually trouLled Ly living clouds, hut the 

 boundaries of the Diffuse Light were tolerably distinct. Alter 8 o'clock, nothing could Le had reliaLly.
