mid the older rocks of north-west Yorkshire and the Lake district 
were recognized as the equivalents of those of Wales. The old red 
sandstone and the great carboniferous series were defined, and together 
with the intermediate beds were carefully indicated on his several 
maps. 
In 1832 Sir Henry de la Beche proposed to the Board of the 
Ordnance Survey that he should colour the ordnance map of Somerset, 
Devon and Cornwall geologically, and a sum of £300 was placed at 
his disposal for the purpose. With this amount De la Beche went 
to work, contributing, however, a much larger sum from his own 
private resources ; and in a few years gained so much ground that he 
and his staff" of surveyors were recognised as the Ordnance Geological 
Survey. Their efforts were in the first years confined to representing 
by colour, the relative areas of tlie several series of formations. At 
the meeting of the British Association at Edinburgh in 1834 resolu- 
tions were adopted, and a deputation appointed, to impress on the 
Government the necessity of a Geological Survey of the northern half 
of this island, and in 1835 the deputation waited on Mr. Spring Rice, 
the Chancellor of the Exchequer, but with slight advantage. In 
1835 also De la Beche made a representation to the same eminent 
financier that the work of the survey should be extended so as to 
embrace a museum, which sliould contain all British materials which 
were useful from an economic point of view. Sandstones, cements, 
and materials useful for building purposes ; metals, ores, and minerals 
having a commercial value ; and every other substance used in 
industrial operations were to be collected and placed in the proposed 
museum. Such collections it was contended would be of the greatest 
value to the people engaged in these industries, and would afford a 
great amount of practical information not otherwise accessible. This 
recommendation was adopted, and a house in Craig's Court, Charing 
Cross, was placed at the disposal of the survey. Large numbers of 
specimens were speedily forthcoming, and the house adjoining was 
added to the one already occupied. This additional accommodation 
was soon inadequate for the requirements of the survey, and in 1845 
the building, now occupied in Jermyn Street, was authorized to be 
used for the exhibition of specimens which had been collected, and
