THE GEOLOGIST. 



with the 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 ]ead 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.
