MANY RARE AND FINE MINERALS 





Have been obtained recently as the result of the purchase 

 of a large collection, the first portion of which (to and 

 including the oxides), embracing some 1,500 specimens, 

 is now on sale. Many specimens from tho Spang and 

 Bement collections arc included. Among species worthy 

 of special mention are : 



Brucite. A score of superb groups from Pa. 

 Hematite. Many magnificent Swiss groups and 

 "Iron Roses." 



Alexandrite. Several large, well formed and gem- 

 my crystals. 



Amalgam. Two crystallized specimens. 

 Acanthite. Several exceedingly good groups. 

 Argentite. Splendid groups. Arquerite. One good specimen. 

 Proustite. Extra choice loose crystals and groups. 

 Pyrargyrite, Polybasite and other silver minerals in fine specimens. 

 Corundum in brilliant, gemmy crystals from North Carolina. 

 Cassiterite. Exceptionally large twins and most brilliant groups — a truly 

 grand assortment. 



Fluorite. Many rare forms and fine specimens, including a three-inch pink 

 octahedron from Switzerland. 



Pyrite. Rare forms and combinations including trapezohedrons and diploids. 

 Chalcocite. Splendid old-time groups from Bristol and Cornwall. 

 Copper. Groups of remarkably sharp and well- developed crystals. 

 Silver. Excellent wire and crystallized specimens. 

 Sulphur. Very perfect loose crystals and beautiful groups. 

 Platinum. Good-sized nuggets and vials of little grains. 

 Iridosmine from several localities, some of it in distinct though very minute 

 crystals. 



Platiniridium. A very little. Palladium. One expensive specimen. 

 Chilenite. Two specimens. Argentopyrite. One fine specimen. 

 Manganite. Several extra fine groups. Cobaltite. Excellent crystals. 

 Hundreds of other very desirable minerals, of some of which there are twenty 

 or more specimens, of others but one. Among them are fine "specimens of Tetra- 

 hedrite, Nagyagite, Bournonite, Octahedrite, Aikinite, Binnite, Jordanite, Sartor- 

 ite, Dufrenoysite, Antimony, Bismuth, Diamonds, Petzite, Hessite, Dyscrasite, 

 Tetradymite, Freieslebenite, Matlockite, Rutile, Brookite, many varieties of Quartz 

 and Opal, Ilmenite crystals. Franklinite in rare forms, Magnetite, etc , etc. It is, 

 of course, impossible to do justice in these few words to so important an accession 

 to our stock. 



The 



DEKALB DIOPSIDE CRYSTALS. 



season's output includes few large crystals but an unusual 



number of 

 beautifully transparent and perfect crystals, -£ to 1£ inches in length. The usual 

 unattractive character of pyroxene specimens finds no counterpart in the flashy 

 beauty of these crystals whose popularity is so well deserved. 



WONDERFUL TITANITE TWINS. 



A new locality in the Province of Quebec has just yielded forty startlingly fine 

 and large Titanite twins. They much resemble the Renfrew County twins, but 

 we have never seen any so good from that old locality.
