STUDY SPECIMENS 



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

 secondary schools throughout the world with mineralogical material. Dur- 

 ing 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 of minerals for analysis will show that European minerals are sold not 

 simply below American prices, but often at lower rates than prevail in 

 Europe. The wide connections of our European house alone permit this 

 economy to the consumer, our prices being the same on both sides of the 

 Atlantic.
