R0WLAND1TE, A NEW MINERAL! 



We have secured the entire available supply of this new and wonder- 

 fully interesting mineral (see A. J. S., Nov. '91). Mr. Hidden informs 

 us that it probably contains twelve new elements (! !) and that its spec- 

 trum embraces 10,000 lines !! An elaborate description by Prof. Row- 

 land and Dr. Hillebrand is promised soon. All the type material not 

 needed for the examination has been purchased by us, and as there is 

 altogether less than five pounds the supply will doubtless prove inade- 

 quate to meet the demand. The mineral is found only massive and our 

 specimens are all excellent though necessarily of but medium sizes. 

 Prices', |5.00 to $20.00. 



THORITE AND ORANGITE. 



Probably the largest lot of good specimens of these two very rare min- 

 erals ever "brought together is now in our store. We can furnish fairly 

 o-ood crystals of Thorite as low as $1.00 and up to $5.00, and splendid 

 masses of Orangite at 50c. to $5.00. These prices are far below those at 

 which these minerals have heretofore been sold. 



VANADINITE. 



The best lot of the magnificent red Vanadinite ever secured by us has 

 just come in and we are selling fine small specimens as low as 25c. 

 Many of those at $1.00 are better than such as would have sold readily 

 for $20.00 four years ago ! Even customers who already have magnifi- 

 cent series of Arizona Vanadinites will find in the present shipment 

 much that will strengthen their collections. 



Curious globular Vanadinite from the original locality in Scotland, 

 50c. to $2.50. 



SULPHUR CRYSTALS, 



The very large collection of magnificent specimens secured by Mr. 

 English in Sicily is astonishing even old collectors who are accustomed 

 to seeing fine specimens of Sulphur. Clearness, brilliancy and perfec- 

 tion are all combined in our superb loose crystals and small groups, at 

 50c. to $1.50. Our large museum groups at $2.50 to $35.00 are grand ! 



SMITHSONITES FROM GREECE. 



The great variety of colors presented in our Grecian Smithsonites is 

 wonderfully pleasing. Rich blues and greens predominate, while drab, 

 yellow, orange, white and other exquisitely contrasting shades are 

 liberally intermixed. For $5.00 we will send an excellent suite of six 

 good-sized specimens, or customers can select the colors they desire at 

 50c. to $2.50 each. Fine museum specimens, $3.50 to $20.00. 



OTHER GRECIAN MINERALS. 



Adamites, a good lot at 25c. to $2.50 ; Serpierite and Aurichalcite, only 

 a very few left at 50c. to $3.50 ; Laurionite, Phosgenite, etc., at 50c. to 

 $2.50. 



RUTILATED QUARTZ IN CHOICE CRYSTALS. 



The best and largest lot of these most attractive inclusions ever in 

 stock ; 50c. to $2.00. 

 For many other recent" additions see our " Winter Bulletin."
