IMPORTANT TO MINERALOGISTS. 



I have the pleasure to inform my numeroue patrons that I have just 

 secured a collection of remarkable old finds from exhausted localities, which 

 was collected by a well-known mineralogist. This collection represents 

 some of the finest crystallized minerals from well-known American localities 

 some of which are not at present procurable. This collection will be placed 

 on sale by January loth. Full details of special list sent on request. 



I can safely state that no dealer has ever had at one time as many Zincites 

 crystallized as there are in my present stock, at prices which will tempt any 

 collector not having these remarkable rare crystals ; also a good stock of all 

 the well known Franklin Furnace minerals. 



COPPER AND SILVER FROM LAKE SUPERIOR. 



I have just received a large lot of excellent crystallized Silver and also 

 Copper, Calcite enclosing Copper, Psilomelane, etc. , in large and small sizes 

 at very reasonable prices. 



COLORADO MINERALS. 



Recent additions to my already large stock of Colorado Minerals include 

 the following : Native Tellurium, Sylvanite, Calaverite, Gold Pseudomorph, 

 Smoky Quartz Crystals, Amazonite Crystals, Topaz, Aquamarine, Caleiovol- 

 borthite, Crystallized Carnotite, Pyrite, Rhodochrosite, Fluorite. 



CALIFORNIA MINERALS. 



In addition to my already large stock of California Tourmalines, I have 

 made special connections with one of the large mining concerns for all their 

 specimens and I have just received as fine an assortment as ever was found, 

 all ranges of quality and color, at reasonable prices. 



I am making special efforts in my gem department to supply Gem collec- 

 tors with rare stones in all sizes, shapes and colors. 



I have also added considerably to my stock of Reconstructed Gems and 

 have the following to offer : Rubies, sapphires, blue, yellow, pink and white ; 

 in all sizes and shapes of the best quality. If you are interested in anything 

 in Mineralogy send for my special lists or request me to send you a ship- 

 ment for your selection, prepaid.
