HARMER : THE PLEISTOCENE DEPOSITS OF EAST ANGLIA. 329 
Fortunately for one like myself, to whom the exertion of 
prolonged field work is no longer easy, there is still much to 
be done in the study. It is gratifying, moreover, to find that 
this classical and important field of inquiry, that of the later 
Tertiary History of East Anglia, which for some years has been 
more or less neglected, is now attracting the attention of a 
younger generation of geologists, who will bring to it new ideas 
and new methods of investigation. 
P.S. — I take the opportunity of publishing here for the 
first time a map of the glacial deposits of Lincolnshire and 
South East Yorkshire, PI. XL VIII., prepared by Wood for the 
well-known paper by himself and Mr. Rome on that subject read 
before the Geological Society of London on November 20th, 
1867. I think it will have a historic interest for Yorkshire 
geologists, as being the earliest of its kind in existence. A few 
copies of the paper, including the map, were printed at the time 
for private circulation. The one in my possession, of which 
this is a copy, was accompanied by a pencil note, in Wood's 
handwriting, stating that the map had been lithographed by 
him for publication in the Quarterly Journal, but had been 
rejected on the ground that it was not sufficiently artistic. 
Figures 1 to 4 are reproduced from the Proceedings of the 
Geologists' Association, Vol. xvii., by kind permission.
