Yorkshire Geological Society

The Society was founded in 1837, the first of its honorary members being Wil l iam

Smith, the father of English geology. T h e objects of the Society are to extend the

knowledge of the science of geology and to promote and record the results of research,

especially that related to the geology of Yorkshire and the neighbouring counties. T o

further these aims, meetings are held in various parts of the country for the reading and

discussion of original contributions to the science, and for the delivery of public lectures.

During the summer field meetings are arranged to places of geological interest.

Candidates for admission to the Society must be proposed by t w o or more members

of the Society. Annual Subscription: ordinary members, one pound; student and

associate members , five shillings. The subscription for Life Membership is one

payment of fifteen pounds, but after fifteen years of ordinary membership the life

subscription is nine guineas. Forms of application for membership and other particulars

wi l l be furnished on application to the Secretary.

T h e Library is housed in the Geological Department of the University of Leeds

and is open to members during University hours. Books may be borrowed by post on

application to the Librarian, the Society paying the cost of postage to the member .

T h e Proceedings are published periodically as Numbers, each Number consisting of

a single paper. These are subsequently col lected and published (usually twice yearly)

as Parts at 12/6 each. They are issued free to honorary and ordinary members whose

subscriptions are not in arrear. Members may, if they wish, elect to receive their

copy of the Proceedings in the form of Numbers instead of in Parts. Back numbers of

Parts are available at the prices listed be low (exclusive of postage) from D r .

H. C. Versey, The University, Leeds, 2. W h e n ordering please include a sum

estimated to cover postage.
