^{page 3 note [e]} Those, who have contended for the Portus Iccius being to the Eastward of the high cliffs on the Continent, have been guided by Ptolemy; who has placed Gessoriacum in the same latitude, but Eastward of the promontory; and there they have been searching for a place to agree with the distance as mentioned by Pliny, lib. iv. c. 16; or Dio Cassius, Hist. Rom. lib. 39; where the first makes the distance 50, and the second 56 miles.

“L'opinion la plus singulière est celle de Malbranq, auteur d'un gros ouvrage sur les Morini, qui suppose, que la mer formoit autrefois un golfe assez profond pour pénétrer jusqu'à Sithiu ou S. Omer, & auquel le nom de Sinus Ittius conviendroit.”

Horsley (Britannia Romana, p. 13, note) knowing that no traces of the Romans have ever been discovered at Calais, in order to get clear of a difficulty, supposed the camp of Julius Cæsar might be buried by the sea. If he had known the sea has been receding from it for a course of time, he surely would not have formed such a conjecture to support his opinion.

^{page 8 note [k]} Rowland's Mona Antiqua, p. 23. § 5. I place no stress upon Itius, or Iccius, being derived from Eitha; but I think is as probable as Chifflet's derivation, where he changes Mardike to Mardiccium, and by dropping the four first letters gets Iccium, and then Iccius.

Itium is also obtained by writing Calais, Calitium, and droping the three first letters. See Somner's Portus Ittius, p. 14, 15, & 21. Mardike is clearly compounded of Mare, and Diick, which, Minshew says, is an old Belgic word for ditch, or a work, cast up against the sea. Such kind of work is still called Dicker work in some places.

^{page 9 note [m]} I believe the advocates for Chifflet's opinion will be puzzled to point out a place eight miles to the eastward either of Calais, Mardike, or Graveling, where the eighteen ships could be confined in a port by a south-west wind; but in the bay near Combleteuse, they would have been fixed with a south-west wind.

In the Cotton Library, Julius, B. iv. p. 25, is a copy of a Survey made A. D. 1565, which contains an account of all the towns, &c. from Hithe to London, with the number of houses in each place, the vessels, inhabitants, landing-places, and other particulars; but there is not any mention made of Deal in it; from which it is plain, as the water has receded, it has been followed by people in building towns.

The Tophus, he says, is the Duckstein (or, as Hill calls it, the Toffstein, or Tustein, of the Germans; and that it differs from the Stalactites in being formed by a gradual deposition of earths, chiefly of the calcareous kind, barely diffused through water, and within the water itself.
