330 TRAVELS THROUGH 



works, and with his and fome other collec- 

 tions of natural curiofities at R.egenfburgh. 



All along the way from Italy through Tirol 

 to this place, I pafled over calcareous, then 

 fchiftous, and at lad aver Granite-hills ; and from 

 t^e higheft tract of this country, which confifts of 

 Granites, I defcended in the fame but reverfed 

 order, over fchiftous and at laft over calcareous 

 hills., in the low'er parts of Bavaria. Remem- 

 ber, that the fame order of rocks and ftones 

 is obferved in the higheft European mountains ; 

 fuch as in the Carpathian hills, the Saxonian ones, 

 the Hartz, in Silefia, in Switzerland, in the Py- 

 renees, in Scotland, and in Lapland ; and it 

 feems to be a fair conclufion, that the higheft, 

 deepeft, and moft ancient mountains, hitherto ob- 

 ferved, confift of Granite, fince that rock conftantly 

 appears in the higheft tracts of mountains above the 

 other fuperincumbent and adjacent ones ; that the 

 argillaceous Schiilus or flate, whether pure or 

 mixed with quartz and mica, that is, whether 

 a gneifs or horn-date, is immediately incum- 

 bent on, or adjacent to, Granites i and that lime- 

 ftone, and other mixed ftone- and earth-ftrata, 

 are conftantly accumulated on this (late, or Schiftus- 

 ground.
