16 GEOLOGICAL MEMOIliS. 



The productive soil around Tokay offers three distinct varieties : — 

 A. Argillaceous soil, immediately originating from the superficial 

 decomposition of trachyte, without any organic remains, not effer- 

 vescent with acids ; this soil is the prevailing one, and gives the best 

 and strongest wines. B. Ehyolitic tufaceous soil, less fit for vini- 

 culture than A. C. Diluvial loam-soil, occurring to some extent 

 only on a hill next to Tokay, producing wines of inferior quality.

EozooN in AusTEiA. By Professor Hochstettek. 



[Proceed. Imp. Geol. Instit. Vienna, January 1866.] 



In South-western Bohemia an extensive system of strata, in which 

 metamorphic schistose rocks prevail, extends from the " Bohmer- 

 "wald " and " Bayrische Wald " to the north banks of the Danube. 

 This system, hitherto ranked among the Azoic rocks, is unconform- 

 ably overlain by the Ginetz beds, containing M. Barrande's " Pri- 

 mordial fauna," and by Pribram Greywacke, in which Dr. Pritsch 

 has found traces of Annelids. Prof. Hochstetter, after long and 

 laborious search, succeeded in finding, in the crystalline limestone of 

 Krummau, agglomerations of calcareous spar and serpentine, which 

 have been declared by Dr. Carpenter, to whom specimens had 

 been sent for examination, to .be undoubted remains of Eozobn. 

 Prof. Hochstetter thinks the lenticular nodules partly composed 

 of calcareous spar and serpentine, so abundant in the vicinity of the 

 graphitic beds of Schwarzenbach and Mugerau, to be possibly of 

 organic origin. Prof. Giimbel, of Munich, has lately ascertained 

 the existence of Eozobn in the crystalline limestones of the '* Bay- 

 rische Wald." 



Prof. Hochstetter correlates as follows the pre- Silurian or Eozoic 

 strata of the " Bohmerwald " and the frontier-mountains between 

 Bohemia and Bavaria, with the analogous formations in England 

 and ISTorth America : —
