Choice Lake Superior Minerals 



We have recently purchased a collection containing many 

 choice specimens of Lake Superior minerals and are pleased to 

 offer the following: 



Silver, showy groups of crystals and irregularly branched 

 masses, 50c. to $20.00. 



Copper, groups of well-formed crystals, $1.00 to $10.00. 



Copper, in transparent Calcite crystals, very beautiful, 

 $1.00 to $8.00. 



Datolite, polished, uncommonly choice specimens, 50c. 

 to $2.50. 



Manganite, a few groups of crystals, $1.00 to $3.00. 



Quartz, a few attractive groups showing considerable vari- 

 ety of forms, 25c. to $2.00. 



We shall be glad to send any of the above on approval to 

 reliable parties. 



A Large Collection Purchased 



We have just purchased a collection of between 3000 and 4000 

 specimens, including many rare species. This will probably not 

 be on sale before January 1st. 



CRYSTALLIZED OEPIMENT 



No little enthusiasm has been aroused by the beautiful Crys- 

 tallized Orpiment from Japan which we recently offered. We 

 still have a few extra line specimens, but they will be gone in 

 the near future.
