OF THE 
Roval Society of South Australia, 
For 1893-94. 
ORDINARY Meretinc, NovEMBER 7, 1893. 
Prof. R. TaTE (President) in the chair. 
Batiotr.—Avueustus Simson, of Hobart, Tasmania, was elected 
a Fellow. 
Exuipits.—Prof. R. Tate exhibited specimens of ochres inter- 
stratified between archean quartzites on the coast cliffs near the 
Gorge of Pedler’s Creek, Noarlunga, which may possibly be the 
residual products from the decomposition of volcanic ash. If 
such should be the case, it would prove thein to be the oldest 
voleanic rocks in Australia. J. G. O. TEepprer, F.L.S., showed 
some new cockroaches from Northern Queensland and the 
Northern Territory. 
Paper.—‘ The Anthropology of the Elder Exploring Expedi- 
_ tion,” by Ricnarp HELms. 
ORDINARY MEETING, DECEMBER 5, 1893. 
Prof. R. Tavs (President) in the chair. 
Exutisits.—S. Dixon exhibited minerals illustrative of the 
gold-bearing rocks of the Murchison Goldfields, W.A. The reefs 
occurred either in diorite or granite. In the former the quartz 
was dark ; in the latter, white. The gold-bearing area appeared 
to be of wider extent than in any other part of the world. In 
connection with the reefs, a moderate supply of fresh water was 
generally found from 80 to 100 feet ; deeper the water became 
salt. J.G. O. Teppsr, F.L.S., exhibited the colored leaf of 
Pancratium rotatum and a diseased leaflet of Ceratonia siliqua, 
which had been reported upon by Mr. D. McAtpine. The 
former he considered due to climatic conditions ; the latter to the 
ravages of the pear-mite, Phytoptus pyrv.
