Fine Molybdenite Crystals. 



Choice crystals of Molybdenite have always been high 

 priced and not at all common. TVe take pleasure, there- 

 fore, in announcing a lot of several hundred from a new 

 locality in the far west which we are able to sell at the 

 lowest prices" ever known. 10c. to $1.50» The crystals 

 are well formed, one inch to four inches in diameter, and 

 have low pyramids about 40° and 55°. 



EXCELLENT FLEXIBLE SANDSTONE. 



Mr Williams recently visited North Carolina expressly 

 for Flexible Sandstone. The result is that we have a 

 large lot of splendid specimens and are able to' sell them 

 very cheaply. Pieces 3x1 inches, 5c; 5x2 inches, 10c: 7x2, 20c; on up to 

 13x2-£, 75c, and even larger specimens. At these prices the mineral is not 

 half as expensive as that from India. Erery collector should have a specimen 

 of this most curious mineral.
