226 REV. W. THORP, B.A. — AGRICULTURAL GEOLOGY, ETC. 
Yorkshire is compared with that of other parts of England, and with 
that of otlier countries ; and mucli consideration is given to rotation 
of crops, and the comparative cost and yield of manures. 
On the 27th of August, 1842, Mr. Embleton received the letter 
which follows from Mr. Wilson : — 
My Dear Sir, 
Mr. Sopwith sends me a letter of Dr. Buckland's, saying that 
Liebig and Playfair are at Oxford, and that he has persuaded them 
to come to our meeting with him, if it be on the 6th September. I 
have to save time written to Lord Fitzwilliam, and hope he will agree 
to the day, and I have also, for the same reason, and because I have 
some grounds to think Mr. Clay may be from home, taken upon me 
to call a Council Meeting at 4 o'clock on Tuesday next. 
I have asked Mr. Thorp to get ready a Geological Paper, as well 
as one on Clover ; j\Ir. Hammerton is to treat of Arboriculture ; and 
Mr. Walker has another Architectural Paper ; Mr. Sopwith offers his 
new Model of Dean Forest, and one of the Somersetshire Coal-field, 
with a paper. 
I have proposed to Lord Fitzwilliam an evening meeting also. 
I hope you will be at Wakefipld on Tuesday. 
Yours sincerely, 
Thomas Wilson. 
Mr. Thorp still continued his researches in Agricultural Geology, 
and at once accepted the invitation of Mr. Wilson to prepare a paper 
on the failure of the red and white clover upon certain soils. Dr. 
Buckland, Professor Liebig, Dr. Daubeny, and Dr. Lyon Playfair 
were present at the meeting. Professor Liebig expressed the pleasure 
with which he had heard the Rev. W. Thorp's paper. He spoke in 
German, and the text of his speech was not preserved. Dr. Daubeny 
also spoke, and Dr. Buckland said it was indeed a matter of great 
importance that agTiculture had attained the position which it now 
enjoyed ; that chemical investigation was being applied so successfully 
to those pursuits on which the growth of the food on which mankind 
depended. Mr. Thorp had given an able analysis of Professor Liebig's 
work, which had opened a new field for scientific research ; but the 
facts now brought forward proved that something more was requisite
