108 WILLIAM SMITH I HIS MAPS AND MEMOIRS 
originals in the Geological Society's possession (Plates X.-XIL). I also 
give a reproduction (reduced) of tlie circular map in The New Bath 
Guide whicli was the basis of No. 2. 
The first in the list is described by Phillips* : — 
One day, after dining together in the house of the Rev. Joseph 
Townsend (29 Pulteney Street, Bath) it was proposed by one of this 
triumvirate (Smith, Richardson and Townsend) that a tabular view 
of the main features of the subject, as it had been expounded by Mr. 
Smith, and verified and enriched by their joint labours, should be 
drawn up in writing. Richardson held the pen and wrote down from 
Smith's dictation, the different strata according to their order of 
succession in descending order, commencing with the Chalk, and 
numbered in continuous series, down to the Coal, below which the 
strata were not sufficiently determined. To this description of the 
strata was added, in the proper places, a list of the most remarkable 
fossils which had been gathered in the several layers of rock. The 
names of these fossils were principally supplied by Mr. Richardson, and 
are such as were then, and for a long time afterwards, familiarly em- 
ployed in many collections near Bath. Of the document thus jointly 
arranged, each person present took a copy, under no stipulation as to 
the use which should be made of it, and accordingly it was extensively 
distributed, and remained for a long period the type and authority 
for the descriptions and order of superposition of the strata near Bath." 
The table referred to, bears the following inscription in the hand- 
writing of Smith : — This Table of Strata, dictated by myself, is in 
the handwriting of the Rev. Ben"' Richardson, and was first reduced 
to writing at the house of the Rev. Joseph Townsend, Pultene>y St., 
Bath, 1799. WiUiam Smith." 
This important table of strata is reproduced in Phillips's "Memoirs" 
(p. 30) and many of the names there given are still in general use. 
The headings are " Strata ; Thickness ; Springs ; Fossils ; Petri- 
factions, etc., etc. ; Descriptive Characters and Situations. The 
Strata given are (1) Chalk, (2) Sand, (3) Clay, (4) Sand and Stone, (5) 
Clay, (6) Forest Marble, (7) Freestone, (8) Blue Clay, (9) Yellow Clay,
