BIBLIOGRAPHY : 
Papers and Records relating to the Geology and Palaeon- 
tology of the North of England (Yorkshire excepted), 
published during 1913. 
T. SHEPPARD, F.G.S. 
For particulars of previous instalments see The Naturalist 
for 1913, page 261. 
A few items omitted from previous lists are now included. 
Most of these refer to Northumberland and Durham, as we 
have only recently had an opportunity of seeing a set of the 
Proceedings of the University of Durham Philosophical 
Society in which they are contained. 
With regard to the papers read at the British Association, 
now that each section publishes the Presidential Addresses 
and abstracts of papers, during the meeting, as well as the 
authors’ copies for the Press, etc., these items appear twice, 
viz., during the year of the meeting and also in the following 
year when the bound volume appears. The former are 
therefore referred to as ‘ leaflets ’ or ‘ wrappers,’ and students 
would do well to bear in mind that as these are often ‘ rough 
proofs,’ or ‘ uncorrected proofs,’ they may differ slightly 
from the papers as they appear in the final report. 
The Yorkshire items for 1913. as well as those for 1910-12, 
will appear in a Bibliography which is being edited by the 
present writer for the Yorkshire Geological Society. It is 
hoped that this will appear in a few weeks’ time. 
The ‘ North of England ’ includes the counties of Cheshire, 
Derbyshire, Nottinghamshire, Lincolnshire, and to the north 
thereof ; including the Isle of Man.
