SPANG COLLECTION OF MINERALS. 



SPECIAL ANNOUNCEMENT.— We have just purchased the cele- 

 brated collection of Mr. Norman SpaDg, of Pittsburgh, and offer it for sale entire 

 for $10,000. If not sold by November 15th, we expect to break it up and dispose 

 of it at retail. The collection contains between 5000 and 6000 specimens filling 

 seventeen cases, 193 drawers and eight glass-front cases; the latter containing 

 many large, showy and magnificent museum specimens. Representing, as it 

 does, the pick of many celebrated European collections, as well as the result of 

 personal visits to many of the best localities throughout the world during the past 

 thirty or forty years, it is uncommonly rich in extra fine examples of the old finds 

 of minerals which it would be impossible to duplicate at the present time. The 

 complete collection will be placed on exhibition in our Philadelphia salesroom 

 about November 1st, and we cordially invite all parties interested to call and 

 examine it. 



Further information will be cheerfully given.
