^{page 167 note 1} This is believed to equate with the terrace between the higher division of the Boyn Hill Terrace and the Taplow Terrace at Furze Platt, Maidenhead.

Between Cookham and Bray the Thames falls 12·11 ft. River-level at Boulter's Lock between these places, east by south of, and the nearest point on the Thames to, Furze Platt (and exactly midway between it and Lent Rise), is 77·84 ft. above O.D. At Boveney Lock; 3 miles farther down the river and 3¾ miles south of East Burnham, mean water-level is noted at 65·31 ft. above O.D.

^{page 168 note 1} It is not unlike that of the deposits, similarly named by the Geological Survey, at corresponding altitudes in the Boyn Hill district of Maidenhead. On the Berkshire side, however, such irregularities as undulations and ravinings are no longer clear because of town development. South, south-east, and south-west of Burnham Beeches most natural features remain unimpaired.

^{page 169 note 1} To the inquirer the workings may appear to bear anomalous designations. Messrs. N. H. Cooper's excavation, although nearer the Beeches, is known as the East Burnham Pit, while that of Messrs. John Deverill, Ltd. (the southward continuation of Mr. Pusey's long-worked-out undertaking), carried on some 250 yards farther to the south-east, is called the Burnham Beeches Pit. In this paper the distinction is made clear by referring to the gravel-pits by the contractors’ names.

As there exist some small pits in fine gravels at greater altitudes within the Burnham Beeches, it is perhaps advisable to refer to the deposits now considered as the ‘East Burnham Gravels’, although termed the ‘Burnham Beeches Gravels’ in some publications.

The deposits to the north, from which the East Burnham gravels are separated by bared Reading Beds, are mapped as part of the great stretch of Glacial Gravels; but the exposure of even horizontal layers, to which Dr. Oakley drew attention, suggests the desirability of inquiry into their exact origin. ‘Field Meeting at Taplow, Burnham and Iver, Bucks’, in Proc.

^{page 172 note 1} The fact that so many diminutive but characteristic flakes and cores occur supports the contention that the anvil method of production could not have served in their case.

^{page 174 note 2} Cores recovered at East Burnham, Lent Rise, etc., assignable to this stage, offer such scope for study that to describe the variants at this juncture would be a trespass on space.
