SAPPHIRE BLUE 



of the true shade is to be found in the popularly named " False Sapphire" 

 or CYANITE from the far-famed St. Gothard. A trip by our collector 

 and considerable work done for us yielded some superb specimens. This 

 locality has been known for over half a century, but like many others in 

 Switzerland, is quite unworkable, save during two months of the year, and 

 rarely visited even then. Thus the specimens are not new — just vastly supe- 

 rior to those in the large museums, all of which have the early specimens, but 

 are fast replacing them with the later ones. 



Months of expert work were devoted to the careful removal of the Para- 

 gonite matrix, exposing the transparent blue crystals associated with lustrous 

 dark brown Staurolites, often in parallel and penetrating habits. This is 

 mentioned in some of the mineralogies, which likewise add "rarely termi- 

 nated." Yet we have perfectly terminated Cyanites six inches long, pene- 

 trating the length of a Staurolite. This peculiarity, together with the 

 contrasting blues and browns standing out on the pearly background, affords 

 one of the most striking combinations to be seen in any collection. 



The stock of really fine specimens is limited and rapidly diminishing. 50c. 

 to $15.00. 



Detached Crystals, 25c. per dozen to $1.00 each. 



Terminated Crystals, 50c. to $2.00 each. 



OTHER SWISS MINERALS. 



We secured by exchange the few duplicates left in one of the oldest of 

 European collections. Among them were the following historical things of 

 hic^h value : Eisenrose, Sphene, Octahedral Rose Fluor, Axinife, AjJatite, 

 Green Fluor, Smoky Quartz, etc., etc. 



EDUCATIONAL COLLECTIONS. 



For 26 years we have supplied mining schools, universities, colleges and 

 secondary schools throughout the world with mineralogical material. Dur- 

 incy that period the quality of our elementary and advanced collections has 

 steadily improved, so that to-day the highest grade of study specimens are 

 offered at unprecedentedly low prices. An inspection of our Laboratory 

 List will show that European minerals are sold not simply below American 

 prices, but often at lower rates than prevail in Europe. The wide connec- 

 tions of our European house alone permit this economy to the consumer, 

 our prices being the same on both sides of the Atlantic. If in Paris this 

 summer favor us with a call— 15 minutes from the Opera Quarter.
