5 are supposed by M. Cogels to be different facies of the same zone. A 

 section at the brick- works of Tamine and Euppelmonde is given. 

 Suggests that some sands there may be Diestian, in which case the 

 terms Diestian and Scaldisian would be synonymous. G. A. L.

 (Prusse). [Devonian of the neighbourhood of Stolberg, Prussia.]

Gives in detail the section exposed by the stream of Yicht near 

 Stolberg, showing a complete series of beds from the Carboniferous 

 Limestone to the Silurian. The Devonian beds belong to the following 

 divisions, in descending order : — 1, Condroz sandstones ; 2, Famenne 

 schists ; 3, Givet Limestone ( Galceola schists wanting apparently) ; 4, 

 Grauwacke (Coblentzian) ; 5, Gedinne schists (Gedinnian). Altogether 

 this series is very like that of the eastern border of the Palaeozoic basin 

 of Dinant. In some matters of detail the author is able to correct 

 Kayser, especially with regard to a limestone subordinate to the 

 Famennes division, which both Kayser and Roemer had referred to 

 the Eifel series. G. A. L.

A description of the rocks and iron-ores in a certain district of the 

 province of Nerike, Sweden. An attempt is made to classify the ores 

 in separate groups according to their age, and to show that each group 

 is accompanied by its own rocks. The following groups are enume- 

 rated : — Eed gneiss, grey gneiss, red eurite, grey eurite, mica-schist, 

 and halleflinta, which latter is the youngest. The paper is accompanied 

 by a coloured geological map of the district. E. E.
