The writer, by means of a table, shows the order of the Cambrian 

 and Silurian rocks in Jemtland (North of Sweden) and their relations 

 to the classifications adopted by Angelin and Kjerulf, viz. in descending 

 order : — 1. Pentamerus limestone = Regie viii. Encrinurorum of Angelin 

 and division 5/3 of Kjerulf. 2. The presence of a representative of 

 No. vii. (regie Harparum) of Angelin, and No. 5 a of Kjerulf, is doubt- 

 ful in this district. 3. CAaswio/^s-limestone, and 4. Middle Graptolite 

 schists together =No. vi. (regio Trinudeorum) of Angelin and Nos. 4 

 and 3/3 of Kjerulf. 5. Orthoceratite limestone=No. v. (regio Asa- 

 phorum) of Angelin and No. 3 a, in part, of Kjerulf. 6. Lower Grap- 

 tolite schists = No. 3 a of Kjerulf in part. Unrepresented in Angelin's 

 classification. 7. Ceratopyfje-\vaie%toTie=l^o. iv. (regio C er atopy gar um) 

 of Angelin, and No. 2, in part, of Kjerulf. 8. Alum-schists=Nos. ii. 

 and iii. of Angelin (regiones Olenorum et Conocoi'ypharum) and No. 2, 

 in part, of Kjerulf. 9. Quartzite:=No. i. (regio Fucoidarum) of An- 

 gelin and 'No. 1 of Kjerulf. G. A. L.

The chief object of the journey was to study the Silurian deposits; 



and in this communication the author makes public the chief features 



of geological and palseontological interest which his time enabled him 



to observe both in the above-mentioned regions and in other localities 



which he visited en route. Throughout he takes special pains to parallel 



the Cambrian and Lower Silurian deposits of Bohemia and Russia with 



the corresponding formations in Sweden. H. A. N,

bung von Idria in Krain. [Explanations to Geological Map of 



the Environs of Idria in Carinthia.] Jahrb. k.-k. geol. Reichs.

The author has fixed the age of the quicksilver-beds of Idria ; these 



are Lower Triassic, but, owing to a remarkable dislocation and overlap, 



they seem to lie below the Carboniferous or Gailthal beds ; their exact 



age is that of the Werfen and Guttenstein (Muschelkalk) beds. At one 



time the plant-bearing beds of the L. Trias were thought to be Lias and 



the Dolomites of the Trias above referred to the Cretaceous. 



The chief formation in the district is the Trias, of which the following 

 divisions are recognized : — (1) Wengenbods ; under these are included 

 sandstones and conglomerates (which may possibly be partly Permian) 

 and beds with fossils corresponding to the Seiss beds of S. Tyrol. (2) 

 Guttenstein group, contains beds whose fossils are similar to the Campilo 

 beds of S. Tyrol, dolomites and nodular limestones : the dolomites are
