WILLIAM SMITH : HIS MAPS AND MEMOIRS

"We have therefore, north and south of the Dun, two east and west 
/anging lines of the coal -measures (similar to, but much shorter than, 
that on the north side of the Yorkshire coalfield), from which two east 
and west ranging lines the coal is known, in both cases, to return and 
resume its regular course. 
" That in Derbyshire, from Eckington to Stubly, is several miles in 
extent ; but it is not from the magnitude, but from the similarity, of 
these irregularities that we may infer the probability of the coal-mea- 
sures in class of the most northerly works in Yorkshire, continuing 
easterly, or resuming a north or north-easterly range, though it may be 
a-t a great distance beneath their unconformably covering strata. —

On the last page of this volume is an interesting editorial note to 
the affect that " A very highly finished and admirable likeness of Dr. 
William Smith, author of Strata identified by their Fossils, and now in 
his 69th year, has been executed on steel, by Ackerman of the Strand." 
This is no doubt the well known portrait appearing in Phillips' " Me- 
moirs " and elsewhere, the original painting of which occupies the place 
of honour above the President's chair in the meeting room of the London 
Geological Society.*

One of the last pieces of work accomplished by Smith was in 
connection with the selection of stone for the Houses of Parliament. 
By the direction of the Government, Mr. Barry, Mr. (later Sir) de la 
Beche and W. Smith were desired to visit the various quarries for 
suitable stone, and also to examine well known cathedrals, etc. 
Eventually, the stone selected was the " firm, yellow, granular 
magnesian limestone of Bolsover Moor, Derbyshiie." Phillips tells 
us that "This was an investigation to which Dr. Smith f willingly 
gave all the earnest attention which it merited, and his previous 
knowledge of nearly all the building stones and quarries in the 
kingdom was found highly beneficial to the Commission. Eive 
days after the signing of the report (in London) he attained his

which see Phillips's Memoirs, pp. 125-126. 
t The honorary degree of LL.D. was conferred upon him by the 
Provost of Trinity College, during the Dublin meeting of the British 
Association.
