INTERESTING MINERALS. 



November has witnessed many large and important 

 accessions to our stock. 



Chalcotrichite from Arizona. A splendid lot of the finest specimens ever 

 found at any locality: large surfaces covered with the richest ruby red and 

 scarlet needles, many of them terminated and stout enough to show clearly the 

 elongation of the cubical into the capillary form. Prices, for extra specimens, 

 $1.50 to $10.00. Smaller and inferior specimens, 25c. to $1.25. 



Hauerite, a few very large and fine loose crystals from Sicily at $4.00 to 

 $15.00 each. 



Norway Minerals. A shipment is just in which includes fine crystals of 

 Glaucodote, Cleveite, Monazite, Cobaltite, Aeschynite, Axinite, Columbite and 

 Alvite. 



Grossularites from Mexico in groups of crystals. 



Pyrite in pentagonal dodecahedrons from same locality. 



Fibrous Chalcanthite in broad veins in the rock, the best we have had, 25c. 

 to $2.00. 



Calcites from Wisconsin, large dog-tooth crystals covered with rhombs; 

 very interesting; 50c. to $2.00. 



Smithsonite pseudomorphs after Calcite from Wisconsin; a choice lot, 

 $1.00 to $3.50. 



Marcasites from Illinois, a great variety of fine crystallized and stalactitic 

 specimens, 25c. to $2.00. 



Chondrodite, a few good crystals from Brewster, N. Y. 



Astrophyllite, Colorado, broad blades, 10c. to $1.00. 



Zircon in single and twin crystals, good, 10c. to $2.00. 



Vanadinite and Wulfenite, a large lot just received, including a few extra 

 choice, at lowest prices, 25c. to $2.00. 



Mexican Topaz, Hyalite, Apophyllite, Valencianite, Opals, Obsidian, 

 Tridymite, Calcite, Amethyst, Cassiterite, etc., etc., collected at the 

 localities during Mr. Niven's tour of five and a half months, and, therefore, sold 

 at low prices and in choice specimens. 



Gold crystals, California, several good specimens, one having a half inch 

 crystal of exceptional sharpness and brilliancy; price $1.00 



Our Catalogue. — On and after December 1st., we will charge 15c. for paper- 

 bound copies of our Catalogue. Notwithstanding the fact that we printed a very 

 large edition our supply is running low, owing to the enormous demand, and we 

 are compelled, therefore, to impose the above charge. We will, however, deduct 

 the price paid for the catalogue from all orders of one dollar or more. Bound 

 copies, 25c. as heretofore. These prices are less than the actual cost. 



"Elements of Crystallography," by Prof. Geo. H. Williams of Johns Hopkins 

 University, (250 pp. 12mo., N. T., 1890) is one of the most recent and valuable 

 additions to mineralogical literature. See A. J. S., Nov. Anticipating that many 

 of our customers will want this book, we have made arrangements to supply it at 

 $1.25 (postage 10c. extra), though the retail price is $1.50. Orders are solicited.
