The fossils of No. 11 are : '' Striated cardia, mytilites, anomiae, 
pundibs and duck-muscles " (sic), and of 12 : " Top covering anomise 
with calcareous cement, strombites, ammonites, nautilites, cochlise 
hippocephaloides, fibrous shell resembling amianth, cardia, prickly 
cockle, mytilites, lower stratum of coral, large scollop, nidus of the 
muscle with its cables." 
With regard to the second document in the series, as Prof. Judd 
points out, it is even more interesting, as it may justly be regarded 
as the oldest geological map in existence, if we distinguish geological 
from agricultural or soil maps. . . . How far William Smith was in 
advance of his contemporaries, is shown by a comparison of this map 
of William Smith, showing carefully indicated lines of outcrop, with the 
excellent map of the Environs of Paris by Cuvier and Brongniart (1809) 
in which colour is spread over the areas occupied by the several for- 
mations, without any clear and definite indications of the actual limits 
ot the outcrops. The colours used by Smith in this map were the same 
as those employed by him in the later maps of 1801 and 1815, and 
thus we have in it the first indication of a scheme of colour now very 
generally adopted by geologists." 
The third document is a copy of Gary's Index to the Map of England 
coloured geologically. It has the manuscript title, General Map of 
Strata found in England and Wales by W^illiam Smith, Surveyor, 
1801."* (See under Smith, 1801). This map was the basis of his later 
map of 1815. " Certain omissions and errors are noteworthy as 
affording the clearest evidence that the map was actually constructed 
at the date written upon it (1801), and that it had no additions made to 
it at a later date. The absence of any colouring for the Tertiary 
Strata of East Anglia and the London and Hampshire Basins, for the 
Wealden area, and for the Jurassic district of the Eastern Moorlands 
of Yorkshire, are especially striking in this connection." 
* It now bears the signature and date : — W. Smith : Feb. 21st, 
1831," this having been put on at the time the docmnent was handed 
to the Society.
