140 DOMAIN IX. ANOMALOUS. 



lowed in their deposition the unequal angles of 

 the cubes, which served them as a base. Some 

 of these fiuors have shown indications of the oxyd 

 of cobalt, others of manganese in stalagmites. 

 Only one piece of fluor has been found traversed 

 by the same pitch-stone : there are also found, 

 but rarely, small cavities which contain little 

 crystals of fluor, barytes, and quartz. 



" It may be judged by the quantity of frag-

 been shaken. It has even been attempted to 

 make mill-stones with the barytes, of which 

 there are large masses, but the attempt did not 

 succeed. All these fragments display much 

 more quartz, mingled with the fluor and barytes, 

 than the rock itself; which, nevertheless, may 

 be said to form a kind of pudding-stone, as pje-

" The environs of this remarkable hill show, 

 in the hollow roads, veins of barytes amidst fluor. 

 The rocks of the adjacent mountain are of pri- 

 mitive grey granite, consisting of felspar, quartz, 

 and mica. It is rather soft, but is used for the
