Vlii PREFACE. 



fering races of animals being found in such 

 situations as evince their creation to have taken 

 place at very distant periods. 



For the several imperfections in this work, 

 which may have escaped the author's attention, 

 he craves indulgence ; hoping that they will not 

 be found of such importance as to render the 

 wish too presumptuous of having it considered 

 as a humble subsidiary to that scientific and 

 most valuable comprehensive work, "Outlines 

 of the Geology of England and Wales," by the 

 Rev. W. D. CONYBEARE and W. PHILLIPS. 



LONDON, 1830.
