[18]. Greater extremes are met with, but they are rare. Hodgson in a note p. 276 says, The foundations in the turnpike-road, just west of Portgate are scarcely seven feet broad; but opposite a plantation a little further west, ten feet and a half. Hutton found the Wall at Brunton only five feet and a half thick.
[19]. This is particularly the case about Old Wall in Cumberland.

[22]. Horsley, in the profiles of the barrier which he gives, represents the marginal rampart or agger as being much larger than the south one. The present aspect of the works does not warrant such a delineation.
[23]. When travelling along the road west of Birdoswald, I have seen a ploughman and his team entirely disappear, on descending into the fosse of the Vallum.
[24]. An inspection of Horsley’s own sections will at once show this.—Britan. Romana, 158.
[25]. In corroboration of this statement, it may be mentioned that an intelligent and substantial farmer offered to take, on a twenty-one years’ lease, the Corchester field, in which the station of Corstopitum stood, at the yearly rate of 6l. per acre. It contains twelve acres.
[26]. The Notitia has Lergorum, but it will be afterwards shewn that this is probably an error for Lingonum.
[27]. The Notitia has Astorum in this and the subsequent instances, but all the inscriptions hitherto found have Asturum.
