The Borough of Lewisham. 
PART I. 
The Geology of Lewisham and the Weigbbourbood. 
By W. H. GrirrFin, 
Hon. Secretary Catford and District Natural History Society. 
HERE is a general impression that no locality 
can possess interesting geological features in the 
absence of exposed masses of fossiliferous rocks. 
This is quite erroneous. Fossils are interesting 
objects, and, moreover, they assist in determining 
the geological position of the rocks which contain 
them ; but, apart from fossils, the acquisition of some knowledge 
of the manner in which the present surface configuration of any 
locality has been brought about, and of the nature of the under- 
lying beds, is a fascinating pursuit. 
No metropolitan suburb affords better facilities for such a 
pursuit than Lewisham and the neighbourhood. 
Although we strongly believe in studying objects rather than 
relying entirely upon information gleaned from books; neverthe- 
less, books are indispensable as tools to work with, and the 
following will be found useful to those who determine to study the 
geology of this district :— 
(1) Huxley’s ‘‘Physiography,” an eminently readable book, 
dealing especially with the London basin and the 
Thames valley. 
(2) Whitaker’s ‘‘Geology of London,” in two vols., price 11s. 
(3) Whitaker’s ‘‘Guide to the Geology of London and the 
Neighbourhood.” A useful little handbook, price ts. 
(4) The last edition of Sir Charles Lyell’s ‘‘Students' Elements 
of Geology,” edited by Professor Judd. 
(5) Jukes-Browne’s ‘‘ Building of the British Isles.” 
(6) Sheet Four of the ‘‘Geological Drift Map of the London 
District,” price 1s. 6d. 
There are two methods in which the geology of a stated. 
locality may be dealt with: from the surface downwards, or from 
below upwards. For the present purpose the latter will be the 
more convenient.
