MINERALS BOLEITE. 



Mr. Cumenge has just returned from a visit of several months to his mines in 

 Southern California. I have purchased the specimens collected by him during 

 this time and saved during several previous months. They were almost entirely 

 obtained by working over the old dumps and he is very confident no more will be 

 .ound. While no very large crystals were obtained this time, there were quite a 

 number of small ones, so that I can offer crystals from 10c. upward. 



Some good groups in the clay or associated with Atacamite were found that 

 can be offerjed at from 81-00 to 810.00 each. 



An extra large list of recent arrivals of minerals will be published nest month.
