A case of splendid specimens of stibnite from Hyago; a 
case of mineral and rock specimens of small size; stibnite, 
Loc Osboin Igo. An interesting historical exhibit of ancient 
mining and smelting in Japan; models and drawings of the 
Anio copper mines: graphite crucibles; large mass of chalco- 
pyrite fromSkiti province: ingots of copper; copper and brasB 
wire. 
Gold and silver from the mines of Sado island, the Aikawa 
and Tsurushi mines : stephanite and myargyrite from near 
the Innai village; argentite from the mountains near Handa : 
argentites with barite and galena from Karnizawa ; a mixture 
of galena, zinc blende, pyrite, chalcopyrite, and gray copper, 
called locally, "kuromono," or black ore, lies in tuff at Kosaka. 
The Towada Mine 
Argentites and copper pyrites in a clay and gypsum gangue 
on the west shore of lake Towada ; the Omaki silver mine of
