exhibits: 



1. Mr. J. E. Carne exhibited molybdenite from Yetholme. 



2. From the Mining Museum: — (a) Phosphate rock from 

 the Wellington Caves, (b) Section of the Southern end of 

 the Bulli Seam at Wongawilli. (c) Chabazite from Emma- 

 ville. (d) Stibnite from Taylor's Arm. (e) Spar from 

 Belubula. (f) Molybdenite from Flinders Island. 



3. Mr. E. C. Andrews exhibited Wollastonite from 

 Yetholme, and Devonian quartzites with Rhynchonella 

 pleurodon. Among the exhibits were some fine examples 

 of contact metamorphism from Yetholme. These consisted 

 of radiating masses of wollastonite with pyroxene and 

 granular garnet, and nodules of wollastonite with nuclei of 

 granular calcite in beds of altered volcanic ash and clay- 

 stone. He exhibited also a large block of Upper Devonian 

 quartzite, containing Spirlfer disjiincta and Rhynchonella 

 pleurodon, obtained from the sediments enclosing the con- 

 tact minerals mentioned above. The latter appear to have 

 been formed by the action of vapours, derived from an 

 intrusive granite, on the Devonian sediments, (b) Molyb- 

 denite and garnet from Whipstick. (c) Molybdenite from
