1892 by Mr. Harker alone. Those from 1893 onward have been 
compiled by myself, and have supplied all the entries in the 
present bibliography from that date to 1908 ; I supplied the 
late C. Fox-Strangways with copies of my lists to be cut up 
for the purpose. Since the present volume has been in hand, 
the bibliographies appearing in The Naturalist have not con- 
tained entries dealing with Yorkshire, except of course, 
such papers, etc., as contained references to other counties as 
well as Yorkshire. For the years 1909 to 1914 {i.e., since Fox- 
Strangways' death), the Yorkshire lists now appear for the 
first time. 
Bibliographical lists relating to the geology of East York- 
shire, which I have compiled, have appeared in the Trans- 
actions of the Hull Geological Society since 1895. 
Useful publications have been issued by the Geological 
Society of London. These ' Lists of Geological Literature 
added to the Geological Society's Library during the year,' 
were compiled by the Librarian, and edited by the Assistant 
Secretary (Mr. L. L. Belinfante). They have been published 
since 1893, and have supplied a number of references, particu- 
larly to papers appearing in foreign journals. 
Since 1890, the Reports of the British Association have 
contained useful ' Classified Lists of the Contents of the Pro- 
ceedings and Transactions of the Corresponding Societies,' 
compiled by Mr. Stewardson, and issued with the Report of 
the Corresponding Societies' Committee. 
In addition, there are the special bibliographies dealing 
with ' Coast Erosion,' ' Underground Water,' ' Borings and 
Wells,' etc., w T hich have appeared in the Reports of the British 
Association and other publications. 
Davis and Lees' West Yorkshire (1880, 415 pp.). contains 
a ' Bibliography on Geology and Physical Geography,' 1674- 
1876 (28 pp.) 
A work of particular value, which seems to be almost 
forgotten, is Bibliographia Zoologiae et Geologic, a ' general 
catalogue of all books, tracts and transactions on Zoology and 
Geology, by Prof. Louis Agassiz, corrected, enlarged and 
edited by H. E. Strickland, M.A., F.G.S., etc' The work
