BOOK NOTICE.
The Geology of the Country around Ipswich, by P. G. H. Boswell, D.Sc. (Geol.
Surv. Memoir), 1927.
The appearance of this Memoir is very welcome, illustrating as it does
and bringing up to date the geology and prehistory of an interesting district
immediately adjoining our own county, in which important discoveries
have been made within recent years.
Occasional incidental references to Essex will interest local geologists,
such as the records of thicknesses of the Eocene rocks at Manningtree,
Halstead, Colchester, Chelmsford, and Maldon, and the occurrence of
fossiliferous sandstones underlying Harwich harbour.
The author makes a shrewd observation on the Glacial Beds of the
district which will apply equally to those of Essex. He says : "There
can be little doubt that the evidence of glaciation in East Anglia has been
considered too much in comparison with the Alpine type of glaciers,
whereas the interpretation of the effects of ice on a comparatively low-
lying coastal plain composed of unconsolidated Cretaceous and Tertiary
sediments gains much more from the recent studies of piedmont glaciation
in such districts as parts of Western Greenland, Alaska and Spitzbergen."
The Memoir is published by H.M. Stationery Office, Adastral House,
Kingsway, W.C.2, at 3s. 6d. net.
