3 i6 SCIENCE PROGRESS. 



very briefly notice Professor Boyd Dawkins' papers written 

 during the period under review. The first of these treats 

 of the Isle of Man (6). A thickness of 1368 feet of deposit 

 is developed near Peel ; these deposits are referred to the 

 Permian system, and compared with the sandstones and 

 "brockrams" of Cumberland, which are known to be of 

 Permian age. At Lien Moar, south-west of the Point of Ayre, 

 after passing through 167 feet of drift, a limestone (referred 

 to the Carboniferous Limestone) was pierced. To the north of 

 this saliferous marls, placed by the writer in the Trias, occur. 

 He concludes "that the Coal- Measures of Whitehaven do not 

 ranee so far south as the Isle of Man. If thev do occur, the 

 only spot where they can be hoped for is in the extreme north 

 of the island, to the north of the Carboniferous Limestone." 

 The second paper by this author to which we have to 

 refer deals with the occurrence of Coal- Measures in the 

 south-east of England (7). He accepts the views of the 

 late R. A. C. Godwin-Austen, lately elaborated by Ber- 

 trand after a study of the folds of France and the adjoining 

 regions, that the great tectonic folds affecting the older 

 strata are traceable by the folds affecting the newer rocks 

 on the surface, though the minor folds are not to be detected 

 in this way. Applying these views to the south-east of 

 England, he points out that the folds occurring amongst 

 the older rocks of the south-west of England are traceable 

 into similar folds affecting the rocks of the south-east of the 

 island. Commencing with the southern folds and working 

 northwards, we have the following alternation of anticlinal 

 and synclinal curves. 



( 1 ) The syncline marked by the Culm-Measures of 

 Devonshire, which is traceable in an eastward direction by 

 the superposed Tertiary basin of Hampshire. The coal 

 beneath this he considers to be probably of the .Culm type 

 and therefore valueless. 



(2) The North- Devon anticline, traceable eastward 

 into the anticline of the Mesozoic rocks of the Vale of 

 Wardour and of the Wealden area. 



(3) The Mid-Somerset syncline, probably represented 

 in the Wealden area by the highly faulted strata north of 

 the Rother.
