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. 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. A n n u a l S u b s c r i p t i o n : ordinary and institutional members, one pound ten shillings ($5"); student members , one p o u n d ; associate members, ten shillings. Forms of application for membership and other particulars wi l l be furnished on appli­cation to the Secretary.

The Society's Library is housed in the Brotherton Library of the University of Leeds and is shelved on the l o w e r stack floor in strips 11 33-64. These books may be consulted or borrowed during the hours w h e n the Library is open and in accordance with the regulations governing the use of the Brotherton Library. A library t icket wi l l be issued to members of the Society on production of a letter certifying membership, which may be obtained from the Society 's Librarian, to w h o m also application should be made for books and periodicals to be sent by post. T h e estimated cost of postage should be included with the application.

Members of the Society are al lowed to consult, and, when books are available, borrow from the geological section of the University Library.

The 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 £ 1 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. Such back volumes as are available may be ordered from the H o n . Librarian, J . H a r t l e y , Esq . , D e p a r t m e n t o f G e o l o g y , T h e U n i v e r s i t y , L e e d s 2 ; prices (exclusive of postage) are given b e l o w .
