' Geology of Cheltenham.' Further, he considers that the underlying 

 sands are the representatives of the lower members of the Inferior 

 Oolite of Gloucestershire, at least for 100 feet of their thickness.

 Haltwhistle [Northumberland]. Ann. Rep. [27^A] Noriliumh. 

 Union of Mechanics' Institutes. 8vo. Newcastle. Pp. 17-21. 

 Describes the glaciation of the district. The great features of the 

 country are the same now as before the Glacial period. Minor differ- 

 ences are described — e.g. the Irthing, which now flows westwards, in 

 preglacial times flowed eastwards into the Tyne at Haltwhistle. Con- 

 cludes with observations on the educational value of Geology. W. T. 



Came, Elizabeth T. Inquiry into the Nature of the Forces that have 

 acted in the Formation and Elevation of the Land's End Granite. 

 Trans. R. GeoJ. Soc. Cornwall, vol. ix. pt. i. pp. 132-151. 



Begins by discussing — 1. The internal structure of Cornwall ; 2. The 

 external configuration of the whole surface ; 3. The jointed structure of 

 the granite ; 4. Its composition ; 5. The dip of the granite and the 

 slate. Then refers to the three theories of the origin of granite : — 

 1, of eruption; 2, of metamorphosis; 3, the contemporaneous theory. 

 Is of opinion that the first two are inadmissible, and only accepts 

 the last in its broader sense, namely, that the circumstances which 

 have influenced the formation of both rocks, and the forces that have 

 acted on them, are closely related. Concludes that the granite was 

 elevated, and the joints and cross-courses formed, by an undulatorv 

 force. C. L. N. F.
