Tus work has been considerably extended, and occupies over 200 pages. — 
It contains an account of the various scientific publications issued from 
Ackworth, Addingham, Barnsley, Ben Rhydding, Beverley, Bradford, wen 
Doncaster, Driffield, Goole, Halifax, Harrogate, Haworth, Hebden Bridge, 
Huddersfield, Hull, Idle, Ilkley, Keighley, Leeds, Malton, Middlesbrough, 
Pocklington, Pontefract, Ripon, Rotherham, Scarborough, Sedbergh, 
Selby, Settle, Sheffield, Wakefield, Whitby and York. In addition there 
is an exceptionally complete bibliography of the various natural history 
journals and publications, now issued for the first time. The author has 
been successful in obtaining many publications not in the British Museum. 
EXTRACT FROM PREFACE:— 
In the following pages an effort is made to indicate the various sources 
of information likely to be of service to a student in his work on any 
branch of natural science dealing with our broad-acred shire. The 
section arranged topographically under towns shows what has been 
accomplished in each place, while the remainder of the book is devoted 
to an enumeration of the general sources of information which should be 
consulted. Unfortunately, several of the items are scarce, in many cases 
only one set being known, a circumstance which has induced me to give 
the bibliographical details rather fully. By a series of fortunate circum- 
stances, and asa result of several years’ collecting, I possess sets of most - 
of the publications mentioned, and shall endeavour to arrange that 
they remain intact for the benefit of future workers, as it will certainly — 
be very difficult, if not impossible, to get such a collection together again. 
It is also hoped that the bibliographical particulars of the various 
journals and Societies’ Transactions will be of service to librarians and 
others who often find it difficult to trace items of this character. I 
believe they are now given in this form for the first time.-
