and descriptions of the natural order of the various strata that are 
found in different parts of England and Wales, to be illustrated by 
a small geological map*. This work was never completed, but it led 
to the publication of his large map, in 1815, for which the Society 
of Arts awarded him their medal and a premium of £50. In the 
same year also his stratigraphical collection of organic remains was 
purchased for the British Museum; this collection having formed 
the basis of his two separate volumes, entitled “Strata identified 
by their Organized Fossils,” 1815, and “a Stratigraphical System of 
Organized Fossils,” 4to, 1817. 
During the six years which followed the publication of his map 
of England, he put forth twenty geological maps of English coun~ 
ties on a larger scale, and several coloured sections across the south 
of England, and a general Geological Section of England and 
Wales, from London to Snowdon. 
Among his unpublished papers were found unfinished and in 
part printed, an introductory work on geology, and preparations 
for a volume on Cconomic Geology, both illustrating the original- 
ity of his views. 
Mr. Wittiam Situ entered on the field of his honourable ex- 
ertions as a Civil Engineer and Mineral Surveyor at a time when 
his labours in geology were but little appreciated, and almost solitary. 
Amidst difficulties and discouragements, and at intervals snatched 
from the duties of a laborious profession, he accomplished the gi- 
gantic work of a general mineralogical survey of England, founded 
almost entirely on his own personal observations, which he ulti- 
mately recorded in a map of fifteen coloured sheets, published by 
subscription in 1815. 
Inevitable delays retarded the appearance of this work nearly to 
the time when a more detailed and perfect map, by a distinguished 
president of this Society, eclipsed in some degree the fame which 
would have accrued to its author had it been published earlier, 
even in the less perfect form to which he had advanced it some 
years before. The sense entertained by this Society of the value 
of the scientific services of Mr. Smith, was marked by their award 
to him of their first Wollaston Medal, in 1831; and was accom- 
* The original coloured copy of this map, dated 1801, was presented 
by Mr. Smith to our Society, and is now in the Museum.
