THEEMAL SPEINGS OF EUEOPE, THE AZOEES, AFEICA, AND THE 



INDIAN OCEAN. 



In Europe, outside of those areas contiguous to the Mediterranean, 

 the thermal springs are located either in regions of faulting and disloca- 

 tion, along the flanks of mountain ranges, or in regions of extinct vol- 

 canoes, as in Central France, Hungarj^, and parts of Germany. 



In Central France there are hundreds of volcanic cones, especially in 

 Auvergne, where the rocks are both basaltic and trachyticj and in this 

 region we find one of the liottest of European springs, viz, that of 

 Chaudes Aigues, with a temperature of 190°.4 F. 



In Germany the springs of Eifel and Bertrich are near extinct volca- 

 noes; and Hungary, where there are five distinct groups of volcanic 

 rocks, is well represented in the list of European thermal springs in- 

 cluded in this chapter. 



The greater number of the springs are, however, found in connection 

 with lines of dislocation, and at the foot or in the midst of elevated 

 mountain ranges. On the north slope of the Pyrenees the springs cor- 

 respond in direction with the trend of the chain: and all along the
