subsequent allocation of the Notitia names is thrown out of course. It is much to be desired that some ‘Witch Stone’ would start from its hiding-place in the foundation of some cottage or castle in the neighbourhood of any one of the stations west of Cambeck Fort, and resolve the interesting question. Until such an event does occur, some doubt must hang upon the subject. The reader will now understand how it is, that, according to some authorities, the stations immediately dependent upon the Wall are said to be eighteen in number, and according to others only seventeen. For the reason just referred to, the Notitia names of the stations are not given on the Map of the Wall westward of PETRIANA. The remainder of the stations of the Notitia were probably out-posts, intended to give support to the whole structure. The difficulty of rightly appropriating the Notitia appellations to such of these as have not yielded inscribed stones, is even greater than in the case of those which follow more closely the line of the Wall. [Sidenote: THE EXTINCTION OF ROMAN NAMES.] Before leaving this subject, the reader will do well to compare the ancient with the modern names of the stations, as far as they are ascertained; in doing so, he will be struck with the almost total absence of any similarity between them. So complete, it would appear, has been the subversion by Pict, and Saxon, and Dane, of the Roman domination in the north of England, that the very names of the cities which were occupied by the empire for centuries have perished, And, like this unsubstantial pageant faded, Leave not a rack behind.
