J. HE bay included between Cap d' Antifer to the east, and the Pointe de 

 Barfleur on the west, is about sixty English miles in breadth* : it is formed by 

 part of the coast of the department of the Seine Inferieure, the whole coast 

 of that of Calvados, and the eastern part of the coast of La Manche. 



The shore of the department of the Seine Inferieure is bold ; generally 

 from four to five hundred feet in height f ; and it is intersected by narrow val- 

 leys, which do n,ot in general run far inland. This hne of high bold coast ends 

 near Cap la Heve. The right bank of the Seine, for many miles into the 

 interior, is, with the exception of the low land between Havre and Harfleur, 

 high and perpendicular : the left bank, from Villerville sur Mer| till about 

 eleven miles east from Honfleur, is formed by high hills, which present at their 

 bases either low cliffs or alluvial plains. The remainder of the left bank of 

 the Seine is precipitous. 



From Henqueville to Dives the coast is hilly, with the exception of two 

 flat sandy plains ; one about a mile in length, between the river Toucques and 

 Benerville Hill; the other, three miles long, between Benerville HiU aad 

 Villers sur Mer. This hilly country is separated from the low land of the 

 environs of Caen by a line passing from the mouth of the river Dives, in a 

 south-east direction, through Etreez. 



From Dives to St. Come, about twenty miles distant, the coast is in general 

 flat and sandy ; there are however some low cliffs, ten or fifteen feet in height, 

 near Lyon sur Mer and Luc. The country rises into hills near St. Come ; and 



* See the Map, Plate XI. ; and Sections, Plates IX. and X. 



t The highest cliff is that which rises immediately to the eastward of the harbour at Fecamp.
