 Administration of their Water Supply," read at the last meeting 

 was further postponed, the President stating that it was the wish 

 of Mr. McKinney and other members of the Society, that the 

 paper should be discussed when the writer was present. 



The following papers were read : — 1. " Notes on some Inclusions 

 observed in a specimen of Queensland Opal " by Mr. D. A. Porter 

 of Tamworth. The President said with regard to Mr. Porter's 

 opinion that the silica composing the opal had been principally 

 derived from the soil through the vegetable matter in which it is 

 included • that he had no doubt that some of these inclusions may 

 be due to that cause, as rushes for instance contain a great deal of 

 silica, but he thought that in most cases the silica had been derived 

 from the deposits in which it was imbeded. 



2. " On some New South Wales Tan-substances," Part 2, by Mr. 

 J. H. Maiden, F.R.G.S.
