ABSTRACT A TEMPORARY exhibition is now on view in the prehistoric section of the British Museum, which includes a sequence of stone implements and flakes found by Mr. J. P. T. Burchell in


the area between Swanscombe and Northfleet in North Kent. The exhibit illustrates Mr. Burchell's correlation of the industries with the glaciations of the Thames area, this involving a


fresh interpretation of the events following the Boyn Hill Terrace deposits. Briefly, his contention is that following on the Boyn Hill or ‘’100 ft.’ terrace, with Clactonian I (abraded and


striated), Clactonian II, Acheulean and early Mous-terian, comes a period of elevation with pauses, causing terraces at progressively lower levels, in which are early Mousterian abraded


implements, until Sunk Channel No. I was cut. These deposits were then sealed by glaciation and the deposit of Combe rock. Melt-water gravels then formed in the valleys and on the plateaux,


which contain abraded implements of the above cultures. A period of elevation and aggradation and submergences followed, in which a thick layer of brick-earth with middle Mousterian


implements was laid down over a wide area. There was then an elevation and an accumulation of sub-aerial deposits containing upper Mous terian and Aurignacian implements with coarse pottery.


This was followed by a glaciation and the deposition of Trail and/or strong loam with ‘rafts’ of Combe rock, the equivalent of the Upper Hessle boulder clay of Yorks and East Anglia. Access
