Rougemont, in L'Age du Bronze, concludes that, though tin was 

 in ancient times obtained from Spain, the quantity was always 

 inconsiderable. Don G. Schulz, the director of the Spanish School 

 of Mines, has, on the contrary, in his Descripcion Geognostica de 

 Gallicia, expressed the opposite opinion. It is much to be wished 

 that we had more information with reference to this interesting 

 question.

With reference to the possible European origin of nephrite, 

 Mr. Fletcher, Keeper of the Mineralogical Collection in the British 

 Museum, has favoured me with the following particulars. 



DEAR Sm JOHN, British Museum, IQth July, 1889. 



Till 1884 no European locality of nephrite or jade was 

 known, though various bits and lumps of the unworked material 

 had been picked up in several places : it was possible that these, 

 like the worked articles, might have been brought by human agency 

 to the places where they were met with. Meyer thinks that some 

 of them were brought by icebergs from Scandinavia, but this seems 

 pure speculation. 



In 1884, Traube announced the discovery of nephrite at Jordans- 

 rniihl, Silesia, in situ [Kais. Leop. Carol, deutsch. Ak. d. Naturf. : 

 Halle, 1884, p. 76]. Kenngott, arguing from Traube' s data, doubted 

 the actual identity of the mineral with nephrite (Xeues Jahrb. f. 

 Min. 1885, band i. p. 238) : Traube re-asserted identity (N. J. f. 

 Min. 1885, band ii. p. 92), stating that the mineral possesses dis- 

 tinct peculiarities. 



Later still, Traube announced the discovery of jade in situ near 

 Eeichenstein, Silesia (JSTeues Jahrb. f. Min. 1887, vol. ii. p. 27")). 

 During the present year, the discovery of jadeite in situ at Piz 

 Longhin, Bergell, has been announced (Neues J. f. Min. 1889, 

 band i. p. 103) by Fellenberg, but a chemical examination by 

 Rammelsberg (Neues Jahrb. f. Min. 1889, band i. p. 229) proves 

 the mineral to be idocrase, not jadeite. 



This is all that is known, as far as I can gather, of the discovery 

 of jade in situ in Europe.. Yours faithfully, 



Sir /. Lubbock, Bart., F.R.S. L. FLETCHER.
