The Map, with sections of the local strata, at the 

 beginning of the Geological Chapter* of this book, is 

 taken from Mantell's Geology of Sussex. The late Sir 

 Roderick Murchison had prepared a somewhat similar 

 diagram, but in consequence of his lamented death in 

 1871 the design was not available. In the pages, 

 however, which he has bequeathed to us, we have the 

 shield of a name illustrious in peace as in war, and a 

 sacred souvenir of a friend as generous as he was 

 noble.
