44^ ON THE TOPAZ OF SCOTLAND. 



Invercauld, and in the Orkney Islands : The sap- 

 phire in different places of the Highlands, as at 

 Benachie and Invercauld in Aberdeenshire, and 

 Portsoy in Banffshire : The amethyst at Invercauld, 

 and in Strathspey, and other parts of Scotland ;

 neralogists. The Topaz of Cairngorm, Isle of 

 Arran, and other places, is rock-crystal of various 

 colours, as yellowish-white, clove-brown, wine- 

 yellow, and orange yellow. The clover brown 

 varieties are named smoke-topaz ; the orange and
