that great department of British industry all the resources of 
science ; but as the meetings went on it was suggested that 
they should be extended to other subjects of a cognate 
character, embracing archaeology and history, though the 
Society remains in its foundation, mainly, geological, and it

interesting a field of geology is presented to us in this great
