COPPER. 



ChrysocoUa , at the Cornwall Copper Mines, in St. Genevieve 

 County, as a thin incrustation with other oxidized products 

 in the chalcopyrite-bearing limestone, by H. A. Wheeler ; 

 uncommon. 



LEAD. 



Leadlnlliie. In small green crystals and clusters, of excep- 

 tional beauty, from a lead mine near Granby, Newton 

 County. See American Journal of Science, Sept., 1894. 



Mimetitey at Seneca, in Newton County, as a thin crystalline 

 coating on galenite, by Dr. W. P. Jenney; rare. 



Artificial Silicate of Lead. Beautiful hexagonal prisms of 

 lead-silicate, resembling Pyromorphite, of an opaque 

 brown to transparent ruby-red color, and with a resinous 

 fracture, from the hearth of a lead roasting-furnace at 

 Bonne Terre, by J. T. Monell, E. M. See American 

 Journ. Science, Aug., 1885, and Sept., 1886. 



ZINC. 



Goslarite, at Joplin, Jasper County, as a white, stalactitic 

 incrustation in the blende mines ; first found very spar- 

 ingly by Broadhead, and later quite frequently in the 

 drainage of the mines, by Dr. W. P. Jenney. 



Ferro- Goslarite, at Webb City, Jasper County, as a brown 

 stalactitic incrustation in the old-workings of the zinc- 

 mines, by H. A. Wheeler ; rare. See American Journ. 

 Science, Mch. 1891 (Vol. 41). 



Amorphous Sphalerite^ as an amorphous, white, pulveralent 

 mass or " natural-paint " in a zinc mine at Jophn, Jasper 

 County, by J. D. Robertson. Only a single pocket of 

 a few tons was found, and was evidentlv the result of 

 recent oxidation of the blende and subsequent chemical 

 precipitation. 



TITANIUM . 



Rutile, in Southeastern Mo., in the granites, as an accessory 

 mineral of microscopic size, by Dr. E. Haworth; rare? 



NICKEL. 



/Siegenite. A new occurrence of this nickeliferous Linneaite 

 has just been found (Nov., 1894) at the Donnelly Lead
