Extract
The specimens described in this note were collected by Mr. Sydney Ryan, Managing Director of the Ryan Tin Mines, and were presented by him to the British Museum through Mr. John Ballot, who brought them to England.
They were found in the stanniferous gravels of the Embabaan district in Swaziland, S. Africa. Their probable source is the granite-gneiss which forms the base of the rock-series in that district.
