WILLIAM SMITH : HIS MAPS AND MEMOIRS 
101 
Through the kindness of Lord Selborne, I have recently had an 
opportunity of seeing the collection of these County Surveys in the 
Library at the Board of Agriculture and Fisheries, Whitehall Place. 
The soil maps are remarkabl} well done in many cases, and there is no 
doubt the}^ were of guidance to Smith in his work. There are references 
to Dunstone, Freestone, Red Marl, Brash, etc., which words Smith 
subsequently used. In some cases, the colouring is remarkably likethat 
adopted by Smith. We know that for several years he regularly 
attended the meetings of various agricultural societies. 
JAMIESON, 1811. 
In the Meinoirs of the Wernerian Society, Vol. I., pp. 149-161, 
1811, Prof. Jamieson in an arf-icle On Colouring Geognostical 
Maps," stated that " the structure of geological maps, upon the 
plan of representing by colours the succession of the strata or formations, 
was also devised by Werner ; so that it would seem, upon the whole, 
that a system coincident with the principles of Mr. Smith, so far as they 
extend, had been delivered in the publications and lectures of Werner 
before the period when the latter began his investigation of the 
neighbourhood of Bath." Werner's printed pubUcations being few, 
however, it is difficult to trace the precise extent of his work. 
The writer in The Edinburgh Review * stated that Since the 
date of Lister's project for ' a soil, or mineral map,' there have been 
published, we believe, some attempts at a geological map of England, 
but we have not been so fortunate as to see them ; and of the numerous 
continental maps, those of the older German writers, of Guettard in 
France, and the recent publications of the Wernerian school, are the 
only ones that have fallen within our examination. The maps which 
Buache published between 1745 and 1761, are described as relating 
more properly to physical geography than to geology ; and they pro- 
ceed upon a visionary hypothesis, about a certain framework or skeleton 
of the earth, which the author imagines to consist in chains of mountains, 
traversing the islands as well as continents throughout the face of the 
globe. The object of Guettard, in his improved collection of 1775, was 
merely to mark upon ordinary maps, in the characters employed by 
chemists, the several mineral substances found at each place; a plan 
obviously very defective and radically different from that which
