CRYSTALS. 



E. H. HARN, Collector. 



If your cabinet is not represented by a suit 

 of those superbly crystalized North Carolina 

 Quartzes, it is lacking in one of its most beau- 

 tiful and attractive features.

 inclusions: Large, movable water drops, as 

 large as peas: Kaolin; Clay, different colors; 

 Wad; Chlorite; Micas; &c. 



Rutilated Quartz in all varieties, clear 

 and amethyst. This is a true gem stone, odd 

 and beautiful. 



Zircons in large, modified and small bril- 

 liant Crystals. 



Occasionally, the following can be sent out 

 in extra specimens: Beryls, Columbite, 

 In piled groups of crystals; Gem Amethyst; 

 Rutile, blood-red. single Crystals; Hidden- 

 ite, the best to be had but none very large; 

 Kyanite, sky-blue Crystals; Octahedrite; 

 Chlorite Crystals; Samarskite; Gum- 

 mite; Tourmalines, fine black with ter- 

 minations, also in groups of doubly terminat- 

 ed Crystals, rare; Garnets, Crystals and fine 

 pieces for cutting, peculiar tint; Monazite. 

 and others. 



I wish to call attention to some magnificent
