 This part is divided under the following heads : — 1. The folds indi- 

 cated by the section from the Perche District to Artois ; 2. The folds 

 shown in cliff-sections of the Channel — A. from Havre to Fecamp, B. 

 from Pecamp to Dieppe, C. from Dieppe to Criel, D. Synclinal of the 

 Criel valley, E. AnticHnal of the Bresle valley, P. Synclinal of the 

 Somme valley, G. Anticlinal of the Boulonnais ; 3. Comparison of the 

 undulations determined by both sections. The anticlinal axes recog- 

 nized are the Perche axis, and those of the Seine, of Bray, of the Bresle, 

 and of Artois. The depressions between these convex folds are those 

 of the Eure (between the Perche and the Seine), of the Yexin (between 

 the Seine and Bray), of the Teres and Therain (between Bray and 

 tbe Bresle), and of the Somme and the Avre (between the Bresle and 

 Artois). G. A. L.
