SOME GEOLOGICAL AND PREHISTORIC RECORDS. 279
Mr. Kennard has picked out a few seeds from the washed
material from the shell-bed that I sent to him, and also a few
small bones. In such a shallow deposit one feels that it is difficult
to be sure that seeds are contemporary, but the site merits
further work, with pollen analysis, so I have placed these remains
in our Museum for future reference. I am indebted to Mr.
Kennard for the appended report on the Mollusca.
I cannot leave the Chair without saying how greatly I value
the honour of having served as your President a second time after
an interval of about 25 years. Owing to the special circumstances
of the time, and through no virtue of my own, I think this gives
me the record in our Club for length of service. It is now with
every confidence and satisfaction that I hand the reins of office
to Dr. Jane.
MR. KENNARD'S REPORT.
It was obvious from the examination of the first sample, kindly sent by S.
Hazzledine Warren, that it was an important deposit and under his guidance I
made fairly large collections from as many loci as possible and these were supple-
mented by much washed material sent by Mr. Warren. The results have amply
justified the labour, for as regards the number of species of land mollusca it is the
richest deposit of Post-pliocene age in England. Only a few species occurred
throughout and most were sporadic, common in one spot and absent from another,
and this is true of land shells today. The shells from the peat and shell-bed are
listed separately, but there can be no question they both belong to one period.
Far more shell-bed was examined than peat, which may account for the
slight differences.
