A HISTORY OF ESSEX 



To the geologist the richly fossiliferous strata of the Red Crag at 

 Walton-on-the-Naze, and the Pleistocene valley -deposits with their 

 many notable remains of mammalia and mollusca, have attracted a large 

 share of attention. 



Our knowledge of Essex geology, due chiefly to the labours of 

 Prestwich, Searles V. Wood, jun., Prof. W. Boyd Dawkins, and Mr. 

 W. Whitaker, has been augmented by the workers of the Essex Field 

 Club and of the Geologists' Association, and notably by Mr. T. V. 

 Holmes. 1 



The following is a Table of the Formations met with in Essex, the 

 names in italics referring to those not exposed at the surface :
