IMPOBTANT TO COLLECTOES 



I take pleasure in announcing that the large collection of minerals 

 recently received, has been thoroughly gone over and properly labelled and 

 is now ready for sale. This collection consists of over 1,000 specimens of 

 excellent quality, some of them from old finds, and almost all very well 

 crystallized. Let me know what you desire and I shall be pleased to send 

 you a selection on approval. 



Indian Belies 



In addition to the minerals, a large assortment of Indian relics were 

 also included: — arrowheads, tomahawks, spears, celts, ceremonials, pipes, 

 scrapers, pestals, implements, obsidian knives, etc., etc. Also an assort- 

 ment of Mexican relics of all descriptions. 



Are You Interested in Gems ? 



If so, you will find my stock now richer than ever before in beautiful 

 examples suitable for both jewelry and specimens. Among the synthetic 

 gems in my stock, all of which are of the finest quality, I have the follow- 

 ing : Rubies, pink, white, blue and yellow Sapphires, and the latest dis- 

 covery, the alexandrite. I have an unusually large stock of common and 

 rare Semi-Precious and Precious Stones, both cut and in the rough. I am 

 able to supply any gem desired, in best quality and all sizes. 



New Minerals 



HODGrKlNSONITE : — I have been fortunate enough to secure the best 

 specimens of this very rare mineral. It is from the celebrated Franklin 

 Furnace Mines and is a rare compound, the formula of which is Mn(Zn 

 OH) 2 Si0 4 . It crystallizes under the monoclinic system and is pink in color, 

 associated with barite. In a few specimens it is associated with the rare 

 minerals pyrochroite and gageite. The whole makes a very pretty specimen. 



BETAFITE : — A member of a group of cubic minerals, niobo- 

 tantalotitanites of uranium, etc., including also blomstrandite (of G. Lind- 

 strom 1874) and samiresite (q. v.); they are closely allied to pyrochlore and 

 hatchettolite, but differ from the former in containing titanium. Betafite is 

 a hydrated niobate and titanate of uranium and occurs in pegmatite near 

 Betafe, Madagascar. Named after the locality. 



Any of the above which may be desired for selection I shall be glad to 

 send on approval to patrons and customers. Information and prices of 

 individual specimens cheerfully furnished upon request.
