THE GEOLOGIST. 
witli tlic copper veins of Serrazzano. Throughout the whole of Tuscany 
the most productive mineral region is that of the borax lagoons. On the 
north-west portion of this area copper ores are found, occurring in veins of 
serpentine rocks. Further towards the south, mines of copper and argen- 
tiferous lead are worked, principally in the Macigno formation, which is 
also the chief repository of the borax. By thus tracing a series of lines 
through all the points at which minerals occur, M. Hauft claims to have 
established the limits and subdivisions of each district. In this way many 
gaps are seen to occur in some places, and these, M. Hauft thinks, indicate 
that many mineral mines must be still unknown, as, for instance, in the 
mountains of Lucca and Pisa ; for the exploration of these unexamined dis- 
tricts, the application of the indications of other mineral zones should be 
of considerable utility, and it is reasonable to suppose that new deposits 
would be found in the prolongation of known areas, or in their immediate 
vicinity. In like manner it has been suggested that, by attention to this 
principle, aided by the records of history, the rediscovery of the old 
Etruscan mines may also be possible.
