HODGKINSONITE, A NEW MINERAL. 



We 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(ZnOH) 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. Prof. Charles Palache has ana- 

 lyzed and will soon publish a description of it. The quantity found is 

 scarcely enough to supply the scientific institutions who will want a speci- 

 men. Prices range from $1.00 to $25.00. 



A NEW OCCUERENCE— Fluorescent Willemite with Rhodocrosite. 



The Willemite occurs in transparent crystals running in size from 2 milli- 

 meters in diameter to almost a hair in thickness. They occur in cavities on 

 Rhodocrosite, making a very beautiful specimen. Under a current they 

 show a strong fluorescence. Prices range from $1.00 to $5.00. 



SYNTHETIC GEMS. 



It is remarkable the interest that has been taken by scientists in these 

 wonderful scientific discoveries. The Corundums are now produced in 

 Pigeon blood, Blue, Yellow, Pink and White. Also the new Indestructible 

 Pearls in strings with gold clasps. These are identical in hardness and rival 

 in color and lustre the real gems. They can be dropped and stepped on 

 without injury and are not affected by acids. My collection of the above is 

 unrivalled, and prices of the same are remarkably low. 



OTHER INTERESTING DISCOVERIES AND 

 NEW FINDS 



Will be found in our new Catalogues. These consist of a Mineral Catalogue 

 of 28 pages ; a Catalogue of California Minerals with fine Colored Plates ; a 

 Gem Catalogue of 12 pages," with illustrations, and other pamphlets and 

 lists. These will be sent free of charge on application. 



Do not delay in sending for these catalogues, which will enable you to 

 secure minerals, gems, etc., at prices about one-half what they can be 

 secured for elsewhere. 



REMOVAL NOTICE. 



Finding that at our recent location we were placed at a disadvantage in 

 receiving and shipping our numerous consignments, we decided to return to 

 our old location, where we are surrounded by the greatest gem and financial 

 district in the world, and are near the vast shipping interests, Custom 

 House, etc., etc Our old offices have been entirely renovated in a beautiful 

 manner, new cases have been fitted and all who take the trouble to call on 

 us will find themselves well repaid by the beautiful display of minerals, 

 gems, curios, etc., etc.
