ABSTRACT OF PROCEEDINGS. XR 
Artesian Basin is absorbed by beds of Permo-Carboniferous 
and Oarboniferous Age. It was pointed out that large 
areas of these rocks occur along the N.E. side of the basin, 
and many of them consist of beds of porous sandstone of 
the former age, and arkose sandstone, equally porous, of 
Carboniferous age. The Permo-Carboniferous beds have a 
fairly consistent dip to the west, and it was claimed that 
water absorbed by them would filter into the artesian basin 
direct. The Carboniferous rocks are in the form of a series 
of anticlines and synclines, with a general synclinorium 
pitching to the west, so that water absorbed by them 
might also be expected to reach the basin finally. The 
altitude of a large area occupied by rocks of these ages is 
as much as 4,000 feet, and it was thought that this would 
have a favourable influence upon the hydrostatic pressure 
of the bore water. 
The paper was discussed by Acting Professor CoTTon, 
Messrs. PooLe, W. R. BROWNE, and the author. 
Monthly Meeting, 11th December, 1918. 
Mr. J. E. CaRNE in the Chair. 
Seven members and two visitors were present. 
EXHIBITS: 
1. Dr. C. ANDERSON :—Ironstone concretions from Coota- 
wundy, near Wilcannia, Bingara Diamond Fields, and 
Tambo, Queensland. 
2. Mr. O. A. SUSSMILCH exhibited specimens illustrative 
of his paper. 
°3. Mr. W. T. WATKIN Brown showed a new meteorite, 
found twenty miles from Yenberrie Wolfram Field, Northern 
Territory. It isa siderite, belonging apparently to the 
class of Broad Octahedrites and weighing approximately 
thirty pounds.
