cipal countries of Europe are collated. In the large diagram four 

 columns are given to Switzerland, contrasting the beds of the Swiss Jura 

 plain and Alps &c., while in five other parallel columns are contained 

 the different facies of the stratified rocks in the chief countries of 

 Europe. A separate column is devoted to palaeontology. E. B. T.

Richardson, Ralph. Notes on the Dutch Peat Industry. (Abstract.) 

 Trans. Edin. Geol. Soc. vol. ii. part iii. pp. 276-282. 



There are three kinds of peat found in Holland: — 1. " Lange turf," 

 commonly called " Friesche turf," is surface-peat, and comes from 

 the " high fens." 2. " Korte turf" is in the form of paste or mud 

 saturated with water, and is got by dredging from the ** low fens " or 

 bogs covered with water. 3. " Derric turf," a layer of peat found 

 under the sand-dunes of the coast of Holland, which has been com- 

 pressed by the overlying sand. The last is comparatively rare, but is 

 used as fuel. No. 2 is superior for fuel to No. 1. G. A. L.

 Zeit. deutsch. geol. Gesell. Bd. xxvi. Heft 2, pp. 225-256. 



In the Trias of South Tyrol dolomites occur at two horizons. The 

 upper series is the " Schlern Dolomite," and the lower the " Mendola 

 Dolomite." The author defends his theory that the Schlern Dolomite 

 represents ancient coral-reefs, and in support records observations on 

 a raised coral-reef on the southern coast of Java. He also describes 

 the beds below the Mendola dolomite. F. W. R.

 Paris Basin.] Compt. Rend. t. Ixxix. p. 817 (abstract). 

 Since the disappearance of the lakes of the Paris Basin its valleys 

 have not deepened or enlarged, but the contrary is the case.
