lamplugh: buried cliff at sewerby. 
C. The Blown-sands. 
A mass of clean yellow sand without admixture, save for a few 
angular blocks of fallen clialk, and an occasional bone, overlapped the 
chalk-wash and was banked up against the old cliff to its full height, 
even passing in places over its brow. In this mass there were obscure 
bedding-planes which dipped down towards the cliff, showing that 
the sand at first accumulated as a high dune fringing the cliff, but 
afterv/ards filled up the hollow and drove on over the sloping 
wold. As in the old beach, so here, there were evidences of violent 
and persistent storms from the south, or from some quarter between 
south-west and south-east. The sand has been driven against the 
hard chalk for so long and with such force that the whole face of the 
cliff has been beautifully smoothed and rounded, as I have attempted 
to show in my sketch. Mr. Reid has already pointed out how 
striking is the contrast between this smooth outline and the rugged 
angular features of the adjoining recent clift'. I think that the action 
of a sand-laden blast would not alone produce this difference, unless 
there were also a more or less complete a^)sence of frost, but to this 
I shall revert later. 
These blown sands may once have been much thicker, and 
perhaps have extended for some distance over the surface of the 
chalk, but they are now cleanly cut out at the top of the cliff by 
the chalky rubble (4) which is nearly continuous, over the chalk 
and seems to form the base of the drifts. 
The glacial beds above the blown sands contain no contem- 
poraneous fossils — unless indeed a few fragmentary shells in the 
boulder-clay be so considered. 
The Fossils. 
Among the fossils found the following have already been recog- 
nized, and it is possible that when the collection has been put in good 
order, and thoroughly examined, additions may be made to the list. 
The asterisks in the columns indicate in which bed the fossil 
was found. 
The only fossils before recorded are Gervus mejaceros, and Bos 
or Bison, by Mr. C. Reid.
