developement of Mr. Thorp's views, and his map and 
section, that Geology was intimately connected with 
Agriculture, and that if they studied it attentively it 
must be of great importance to them in an economical 
point of view. He was much interested by Mr. 
Thorp's statement of the different crops which grew upon 
different strata, clearly shewing some relation between 
the vegetation and the substratum of a district. He had 
read Sir Humphrey Davy's views on this subject in his 
valuable work on Agricultural Chemistry, and had also 
heard of the important results which Mr. Coke (now 
Earl of Leicester) had obtained by mixing lime and sand 
and clay in such proportions as to obtain a soil almost 
permanently fertile. But it seemed by Mr. Thorp's state- 
ment, that great improvements could yet be made, and 
he thought Mr. Thorp was fully competent to the investi- 
gation of the subject, because he was well acquainted with 
chemistry and geology, as well as with practical farming ; 
and he hoped he would be able to throw much additional 
light upon agriculture. If by this combination of 
chemical and geological information, and its application 
to practical agriculture, they should succeed in obtaining 
the greatest possible fertility of the soil, the labours of 
this society, and of Mr. Thorp in particular, would not 
have been in vain. Before he sat down he would take 
the liberty of requesting the noble Chairman to call 
upon a distinguished geologist, who was in the room, to 
favour the society with his views on the subject. 
Earl FiTZWiLLiAM said he wished to ask Mr. Thorp 
a question on the subject of his paper. He had alluded 
to the artificial admixture of sand with clay soils and 
clay with sandy soils. He wished to know whether in 
his researches upon the subject, he had found that such
