Maritime geography and statistics, or A description of the ocean and its coasts By James Hingston Tuckey (1815):
The English channel,
La Manche of the French,
Oceanus Britannicus, is 276 miles in length from the Strait of Dover to the Land's End, and its breadth between this latter point and Ushant called by seamen the
Chops of the Channel, is 100 miles. In general this gulf or internal sea is without shoals or dangers except near the shores. The depth in mid channel from the Land's End to Dungeness is from fifty six to eighteen fathoms.
