 Sir Archibald Gcikic, F. R. S. etc. Director of the Geological Survey

 of olden time phenomena by present ones, the progression in organic 

 types, &c., &c., which with views held by Sir James Hall, William 

 Smith, Kelvin, Playfair and others, placed the main results and leading 

 objects in view on a scientific and practical basis. 



Many opposing forces had to be met. Preconceived notions, 

 theories and so-called orthodox views of learned men of the days of 

 Hutton, all assailed the new th2ory. But it was founded on facts and
