Since 1884, particulars of the various geological mono- 
graphs, etc., bearing upon the northern counties of England 
(Notts., Cheshire, Derbyshire, Lincolnshire, and to the north 
thereof, including the Isle of Man) have been published. Up

1902-8 appeared in the Tvansactions of the Yorkshire Natura- 
lists’ Union part 34, for 1908. 
The present instalment includes the entries for 1909, 
with the exception of the Yorkshire items. These are shortly 
appearing in a memorial volume to the late C. Fox-Strangways,

the present writer, and it seems unnecessary to duplicate the 
items.
