The worthy and ingenious Patrin says, that 

 he himself discovered that of Daouria, in the 

 mountain Odon Tchelon, which furnished him 

 with many topazes, and prisms of beryl of an ex- 

 traordinary size. He observes, that the quartz 

 rather forms carcases of crystals, imperfectly 

 hexagonal, the most usual form of that sub- 

 stance : and he regards that of Scotland as of a 

 different crystallisation, the felspar appearing to 

 have been formed in rhomboidal prisms, while 

 the intervals have been filled with a quartzose 

 fluid, bearing no evidence of crystallisation.
