PI^K OAffc^ETS ! ! — Intelligence has just reached us from Mr. 

 Niven that he has made a big strike of these new and wonderfully 

 beautiful Mexican Garnets. Until now we have had ten orders for 

 every crystal we could get. We hope inside of a month to be able to 

 fill all orders. The color is a delicate pink, the crystals good sized 

 (averaging an inch in diameter) and of the rhombic dodecahedron 

 form. Particulars can be better given next month. 



$500.00 OPA.Ii. — We are assured by the owner of the mine in Aus- 

 tralia from whom we secured this magnificent specimen, that it is the 

 largest and finest ever discovered. The predominating color is a deep, 

 rich blue and the brilliant green which plays through the blue is truly 

 wonderful. 



Extra Fine Silver Minerals now in Stock. 



Mr. Niven's present Mexican trip has been yielding us some really remark- 

 able specimens. It is not unlikely that a new selenium-silver species will be 

 announced shortly. Several splendid Pyrargyrite specimens are already in 

 — two at $50.00 each ; also a number of very choice Argentite crystals, Poly- 

 basite crystals, Stephanite crystals, Embolite crystals, and Iodyrite.
