apparent from the geological surve}^ map, although there is evidence 

 of much faulting, folding, and unconformity. There are good views 

 of tlie TJsk and Sugar-loaf, of the Blorenge, and of the serpentine 

 curves of tlie Wye. Agriculture, mines, and minerals are also dealt 

 with. The alluvial levels bordering the Severn, locally known as 

 "the Moors", are said to contain the deepest and ric\\est soil in 

 the county. 



In the volume on the Isle of Man the geology is not satisfactory : 

 it is remarked that "Underneath all rocks is the primeval granite, 

 the foundation material of the earth's shell", and that the "very 

 early granite " of Dhoon and Foxdale is covered by " Primary rocks, 

 which may conveniently be tei'med Cambro-Silurian, i.e. of the same 

 structure and formation as the Cambrian, the Ordovician, and the 

 Silurian rocks of Wales". As the geological map at the end of the 

 volume, based on that of the geological survey, jiives these rocks as 

 Manx Slates (Cambrian ?), the author might well have referred to the 

 Survey memoir by Mr. Lamplugh to aid him in his geological 

 descriptions, and he would then have learnt more about the " vast 

 deposits of marl " beneath the surface in Kirk Andreas and Kirk 

 Bride. In other respects the volume is full of interesting information, 

 including remarks on place-names and surnames, antiquities, etc. 

 The illustrations are effective, but those of Spanish Head, Calf Island, 

 and Sulby Glen are not so clear as the picture of the Manx cat and 

 many others. In the volume on Carnarvonshire the author acknow- 

 ledges help from ilr. E. Greenly in the geological chapter, which is 

 excellent though brief. Mines and quarries are separately dealt with, 

 and there are views of the Penrhyn quarries. As remarked, there is 

 a reduced demand for roofing- slate, as tiles are now more generally 

 favoured by architects. Other views include the precipices of Carnedd 

 Dafydd, Snowdon, Aberglaslyn Pass, Dolbadarn, and a group of black 

 cattle. A concise history of the county may be mentioned among the 

 many topics dealt with in this volume.

1. CoTTEswoLD Naturalists' Field Club. — In part ii of vol. xvii of 

 the Proceedings of this Club (November, 1911), Mr. L. Richardson 

 contributes a paper on " The Inferior Oohte and Contiguous Deposits 

 of the Chipping-Norton District, Oxfordshire ", describing in detail 

 the succession of strata seen in numy quarries in connexion with the 

 'Chipping Norton Limestone', so named by Hudleston in 1878. 

 That limestone is newer than the Clypeiis Grit -of the Inferior Oolite, 

 and represents the Lower Fuller's Earth; it is succeeded by a series 

 of dark clays, together with marls and sandy limestones of estuarine 

 character, to Avhich the name ' Neseran Beds ' has been given by 

 Mr. E. A. Walford, while above comes the Great Oolite. In the 

 Swerford area Mr. Richardson notes four subdivisions in the Chipping 

 Norton Limestone, while elsewhere seventeen subdivisions are noted 

 in the Neaeran Beds. Local evidences of non-sequence between the 

 Chipping Norton Limestone and beds above and below are indicated.
