The conglomerates probably occur on many different horizons, but: 
when traced northwards into Scotland, they are associated with red 
and yellow sandstones containing undoubted Upper Old Red Sand- 
stone fishes. Several basaltic dykes (in part, probably Tertiary) 
occur in the area. The remarks on igneous and eruptive rocks are: 
based to some extent on researches made by Mr. Teall, but the 
author gives the result of much personal observation, and his notes 
on crushed granite are of especial interest. 
A short chapter is devoted to Glacial Deposits, the author remark- 
ing that the higher summits of Cheviot, etc., seen never to have 
been over-ridden by foreign ice, but to have acted as independent 
centres of glaciation. There are also notes on recent accumulations 
(peat mosses, etc.), on the physical structure of the district, on 
some aspects of scenery in relation to geology, and on the economic 
resources of the area.

J. H. Buaxg, F.G.8., ete. (Parts by H. B. Woopwarp, F.G.8.,

N this Memoir we have descriptions of the Chalk, Pebbly Series 
(Bure Valley Beds), Glacial Drift, River Gravel, and Alluvium. 
The district occupies the central portion of Norfolk, and includes 
(besides East Dereham) Litcham, Reepham, and North Elmham. 
Geologically speaking, the country is but little known, the pre- 
viously published notices being confined to papers by the late 8. V. 
Wood, jun., and Mr. Blake, and to references by the late C. B. Rose. 
A full list of fossils from the Chalk is now given, and detailed notes 
of the various pits and sections exposed. The Pebbly Series has 
yielded no fossils in the area now described, and its precise age is a 
subject on which opinions differ, Mr. Blake grouping it with the 
Glacial Drift, while Mr. H. B. Woodward places it in the Norwich 
Crag Series. A large part of the area is covered by the Chalky 
Boulder Clay, and this is overlaid in places by coarse “ cannon- 
shot”? gravel and sands. Notes on the economic resources, and 
records of a number of well-borings are given.
