Abstract
AT a meeting of the Royal Anthropological Institute held on June19, Mr. H. J. E. Peake in the chair, Prof. P. G. H. Boswell and Mr. J. Reid Moir presented a paper on “Flint Implements at Foxhall Road, Ipswich.” Prof. P. G. H. Boswell dealt with the geology of the deposits. The site lies in an oval hollow about 120 ft. above Ordnance datum, ij miles E.N.E. of Ipswich station. The surrounding plateau of glacial sand and gravellies at about 130 to 140 ft. above Ordnance datum. The succession of general sequence of deposits from bottom to top down to a depth of 31 ft. 4in. is as follows: Dark Chalky-Kimmeridgic Boulder Clay (bored to 2 ft.6 in.), loamy sand and shingle (6 ft. 9 in.), sandy boulder clay and loam (3 ft.), gravelly and sandy brick-earths passing up into laminated brick-earths (15 ft. 3 in.), gravel and subsoils, etc. (3 ft. 10 in.). Mechanical analyses of the respective beds have been made, and as a result suggestions were offered regarding conditions of deposition. The mineralogical characters have also been worked out, the assemblage being of typically glacial character. Reasons for referring the lowermost deposits tothe Chalky-Kimmeridgic Boulder Clay were given, and the evidence that the uppermost gravel indicated a recrudescence of cold or even glacial conditions after a period of amelioration were discussed. Finally, tentative correlations with the glacial sequence in Lincolnshire and Yorkshire were attempted.
