Object of Book. 37 



first describe in some detail and in chronological order 

 all the rocky formations that constitute Great Britain, 

 with reference, where it can be done, to the Physical 

 Geology and Geography of each large special epoch, 

 for only in this way may we hope to get an idea of how 

 our island at length got into that phase of its history 

 in which we happen to live. If the reader has been 

 able to follow me in what I have already written, I 

 think he will understand what I shall have to say in 

 the remaining chapters.
