PREFACE 



THE object of this little book is to give a clear and 

 accurate statement of facts bearing on the character 

 of the debatable ground intervening between the 

 later part of the geological record and the begin- 

 nings of sacred and secular history. 



The subject is one as yet full of difficulty ; but 

 the materials for its treatment have been rapidly 

 accumulating, and it is hoped that it may prove 

 possible to render it more interesting and intelligible 

 than heretofore,
