The Rev. William Thorp, of Womersley, then read a 
continuation of his Illustrations of Yorkshire Geology." 
The Council regret that they are not permitted to publish 
it, but they trust that Mr. Thorp will in some other form 
give to the world this valuable series of papers on the 
Yorkshire Coal field, the result of many years' laborious 
investigation of the mineral geology of this county. 
Mr. Laurence, of Leicester, referred to several speci- 
mens of fossil fruits which he had brought from the coal 
formation of Lancashire. He washed to ask of any practical 
geologist who might happen to be present, whether similar 
specimens were found in the Yorkshire coal formation. He 
had never heard of any or seen them, and he was inclined 
to believe that they existed only in the locality near Bolton. 
Mr. Sharp believed that similar fossils had been found in 
many other parts of the country. 
Earl Fitzwilliam remarked, that it was very desirable 
that they should obtain as much knowdedge as possible of the 
fossils contained in the different strata, that they might by 
that means be enabled to identify the various beds of coal in 
different localities. He believed that five or six years ago 
the remains of the scales and shells of fish were found im- 
bedded in some of the coal seams. Now if they found the 
scales of fish in connection with a particular seam in the 
northern part of the Yorkshire coal field, and also found the 
same scales in a bed, even of different thickness, in the south- 
ern part of the coal field, it would be a strong reason for 
believing that the two beds were identical. 
Mr. SopwiTH observed, that although vegetable impres- 
sions were extremely abundant in the shales and other strata 
associated with coal, yet he believed that such impressions on 
the surface of the coal itself, were of rare occurrence, and 
he had met with persons of great experience and observing
