BEAUTIFUL MUPHIMY QUARTZES. 



During a recent personal trip to this region, so well known to mineralo- 

 gists, we acquired the following at the localities : 



aUARTZ VAR. ROCK CRYSTAL. 



From the old mine of La Gardette above Bourg d' Oisans, were recently- 

 taken a quantity of crystal groups which are the equal of any in the Euro- 

 pean museums. We secured the pick of the find, and supply all sizes at - 

 about double the prices obtained for the Arkansas quartzes. The Dauphiny 

 type is the well known slender three to four-inch crystals, with one rhombo- 

 hedral face abnormally developed. Their great brilliancy and limpidity 

 also serve to distinguish them from the American. As the mine is rarely 

 worked, the opportunity is exceptional. 



(Loose crystals in. quantity for schools.) 



Chalcopyrite, Bourg d' Oisans. Large tetrahedral crystals, with, a splen- 

 did iridescence. Suggestive of the Ellenville and Cornish specimens. 



Anatase. A few choice examples of both yellow and black varieties. 



Siderite. Allevard. Few specimens have been found in the last dozen 

 years. Showy groups of brown rhombs, some with clear quartz. 



Chrysolite Crystals, Maillargues, Cantal. Sharp and bright, 5 to 10 mm 

 diameter. 



Josephinite, Grants Pass, Oregon. The largest pebbles yet seen of this 

 rare nickel-iron mineral. 



Guanajuatite. Mostly fragmentary. 



Gem Rose Beryl. A few of the rare California beryls direct from the 

 locality. The crystals show exceptionally sharp angles and interesting 

 planes. 



The rose tint greatly enhances their value.
