1854.] STEPHEN AUSTRALIAN GEMS AND GOLD. 305 



Catalogue of Precious Stones and Minerals from Australia *. 



A. A blue and white Sapphire, so much water- worn as to have 

 lost all its crystalline faces but one. This, with some others in my 

 possession, came from Ballarat, in Victoria. 



B. A hediVitMxA Sapphire : hexagonal crystal ; in blue and white 

 bands (as described by Dufresnoy): from the Hanging Rock Diggings, 

 on the River Peel, in New South Wales. 



C. A highly perfect crystal of Spinel Uuby (of fine colour), in one 

 of its ordinary forms ; a flat triangular crystal, with the edges re- 

 placed, and the angles depressed : from the Peel River Diggings. 



D. A water-worn octahedral crystal of Spinel Ruby ; found in the 

 same locality. 



E. A Ruby of good colour ; from the same locality. 



F. Are small Chrysolites ; from the same locality. 



G. Are Zircons, obligingly selected by Professor Tennant out of a 

 parcel of various stones brought to me from the River Ovens, in 

 Victoria f. 



H. A Spinel Ruby, in a similar triangular crystal to C, though of 

 inferior transparency and colour ; from the River Ovens. 



I. Are "pepitas" of Oxide of Tin ; from the same locality. 



J. A prism crystal of Tourmaline ; from the same locality. 



K. A striated fragment of a pale yellow Topaz ; from the same 

 locality. 



L. Oxide of Tin, in the form of sand, with gold dust and decom- 

 posed felspar (called "pipe-clay") &c., taken as a sample from a 

 bag received by me from the River Ovens. 



M. A Garnet, in a dodecahedral crystal (imperfect) ; from the 

 same locality. 



At Peel River, also, they find dodecahedral garnets, whilst at 

 Mount Alexander Pyropes and common Garnets are met with. 



Sir Thomas Mitchell deposited in the Museum of Practical Geo- 

 logy a Diamond, said to have been found in New South Wales. 

 He also brought thence to London some limpid White Topazes %, 

 almost as brilliant as those found in water-worn pebbles at Cape 

 Barren Island in Bass' Straits, and which I have seen cut and 

 equalling in brilliancy the celebrated Nova Mina Topaz of the 

 Brazils. 



Very fine hexagonal Beryls, exceeding an inch and a half in 

 diameter, and in parts highly transparent, are found in South 

 Australia, at Mount Crawford. 



Tourmalines, also, of a very considerable size, are found at En- 

 counter Bay in that colony, and also in D'Entrecasteaux's Channel 

 in Van Diemen's Land. 



An Emerald in a hexagonal crystal is stated to have been found 



* These specimens were exhibited at the meeting of the Society. 



t Mr. Foord, a very scientific metallurgist and gold assayer in Melbourne, 

 showed me some Zircons from the same locality, in August 1853. 



% Sir T. Mitchell has lately presented some specimens of Australian Topazes to 

 this Society.
