ZODIACAL LIGHT.— August, 1858. 



August 4th, 7 h. p.m. — Very distinct. 

 August 31st, 7 h. p.m. — Not very well defined. 



Whenever the sky was obscure, the Zodiacal Light was 

 visible ; but it was particularly well defined on the 2nd, 3rd, 

 and 4th of August, so as to admit of ascertaining the position; 

 and chiefly the southern edge was well defined, while the 

 point and northern edge were less distinctly visible. 



On the 3rd the following positions were taken : —

South Edge.
