140 COAL-FIELD OF CLACKMANNANSHIRE. 



the coals and their accompanying strata, as repre- 

 sented by the curved dotted line a a, Fig. 1. 

 Plate IV. Upon considering all circumstances con- 

 nected with this point, I am inclined to think, that 

 these mountain rocks do form a curve at a consi- 

 derable depth from the surface, and that the coal- 

 fields represented in the section lie in a conforming 

 situation with the transition rocks. 



It is of importance here to remark, in particular, 

 that this section of the Clackmannanshire coal- 

 field and its position with the transition rocks, ex- 

 actly corresponds with the geological views and 

 statements of Werner, regarding coal-fields, and 

 accords precisely with the distinct and clear state- 

 ments given by Professor Jameson, the President 

 of this Society, in his Geognosy. 



In taking a general view of the section, and of 

 the three coal-fields formed by the two great slips 

 or dislocations of the strata, we are very naturally 

 led to conclude, from each coal-field being so nearly 

 similar to each other as to the coals and accompany- 

 ing strata, that the three coal-fields once formed a 

 connected whole ; but if this was the case, a very 

 interesting inquiry arises : What has become of all 

 the coals and accompanying strata which must have 

 then existed betwixt the dip part of the coals ad- 

 joining the slips in the one coal-field and the crops 

 of the same coals now found at a great distance 

 from them ? perhaps the fragments of coal and of 

 their a companying strata, which are found so abun-
