Meeting of the British Association — Exeter, 1869. 453 



This extensive diffusion of similar forms of plants during the older 

 Miocene period speaks to us of a widely extended uniform climate, 

 contrasting strongly with the climates which now prevail in the 

 temperate and Arctic regions of the northern hemisphere. 



There is another matter connected with the geology of Devonshire 

 which has special interest. This is the caves of this county, and 

 their contents. These have been made the subjects of many 

 valuable communications to this section by Mr. Pengelly and the 

 gentlemen who are associated with him in the Committee for the 

 exploration of Kent's Hole. But as we now are in a locality so near 

 the source whence so much of interest has come, I believe that this 

 section will again have before it important matter referring to Kent's 

 Hole, and other Devonshire caverns ; and I cannot doubt that many 

 members of the British Association will avail themselves of the 

 opportunity of examining the spot whence so much valuable 

 information has been derived bearing upon the early history of the 

 human race. 



Geology and Archeeology are now shading into each other, and 

 although the early history of man remained for a long time like 

 distant land, dim and ill-defined, — of late, owing to the labour of Sir 

 Charles Lyell, Sir John Lubbock, and others, we are acquiring 

 a clearer conception of our early ancestors, of their mode of life, 

 and the conditions under which they existed.
