STRATIGRAPHY 



It will be convenient to mention first those books and memoirs 

 which are of a general nature but yet give more information about 

 certain formations than will be found in this volume. 



The most complete Manual of Geology in English is Sir A. 

 Geikie's Text-book of Geology, 4th edition (1903) published by 

 Macmillan and Co. in 2 volumes, price 32s.. The second volume 

 deals with Stratigraphical Geology and includes accounts of the 

 foreign equivalents of each system, not only in Europe but in other 

 parts of the world. A similar work in French is De Lapparent's 

 Traite de Geologic, 5th edition (1905), in 3 volumes, price 35s. 



A useful epitome" of the geology of many counties and districts 

 in England and Wales will be found in the Jubilee volume issued 

 by the Geologists' Association in four parts, price 5s. each (1910). 

 Each article in this publication has been written by a geologist 

 who is specially well acquainted with the district he describes. 



The Geological Survey has published the following memoirs, 

 which deal either with special formations or with districts of 

 considerable size and importance : -
