C.E., as Hon. Treasurer. 
ELECTION or MEMBERS or COUNCIL.—Samuel Dixon and W. 
H. Selway. 
ExHIBITS.— A. H. 0, Zrztz, F.L.S. a large, sound-pro- 
ducing, ground spider, from the Malay Peninsula, and cop- 
per ores from Paull’s Creek Copper Mine, South Australia. 
E. ASHBY, bird skins from Woodford, Queensland, Malurus 
lamberti and M. melanocephalus, and, for purposes of com- 
parison, M. assimilis, from Ardrossan; Kopsaltria magniros- 
tris, Platycercus palidiceps, and Iypotnædia Philipinensis. 
W. Н. Serway, a piece of shale with dendritic markings. 
Н. Basepow, “ironstone biscuits." The exhibitor stated 
that during a sojourn at Cape Jervis concretions were 
found on the surface of the glacial deposits oceurring in that 
neighbourhood. Their shape and external characteristics are 
similar to the limestone “biscuits” of the “biscuit flats”: but 
in this case the composition is hydrated oxide of iron. It 
was suggested that they might be true pseudomorphs 
of ironstone after limestone. No examples were, how- 
ever, found showing an intermediate stage of  pseudo- 
morphism, so that, if they be true pseudomorphs, the 
molecular replacement has been effected in so perfect a man- 
ner that the specimens, with the exception of their superior 
hardness, might easily be mistaken for the darker-coloured 
varieties of the “limestone biscuits.” Mr. Howcutn stated 
that discoid and nodular concretions of limonite were com- 
monly found in the upper part of the glacial beds of this 
age, and, as the physical conditions under which they oc- 
curred at Cape Jervis were not the same as those of the “bis- 
cuit flats," he would be inclined to regard them as segrega- 
tions of ironstone in the clay itself, or at the line of junction 
between the clay and overlying sand rock, as was the case at 
Queenstown, Kangaroo Island. The. specimens exhibited 
showed sand grains cemented by the hydrated oxide of iron, 
which seemed to support this view.
