provinces of Spain, lying on the Bay of Biscay. This work treats of the 
Physical Geography of the Province, and its general geology, and par 
ticularly of its metalliferous deposits, mining industry, and ores, and is 
illustrated by a number of detailed maps. The subject of the ores is 
treated mineralogically and chemically, and also with reference to their 
geological age and the order of succession according to which the differ- _ 
ent kinds were formed. A chapter containing five plates is devoted to 
the deposit of sulphate of soda in the valley of the Jarama near Aran- 
Juez, Province of Madrid; and another to observations on the mammil- 
lated, reniform, globular and botryoidal structure in minerals.
