things to continue until the catalogue was exhausted.” Whilst 
Mr. Ferguson, (C. and W. Antig. Trans., vol. 3, p. 93), after 
discussing the two sets of stations in sections 52 and 63 of the 
Notitia, says “that the Notitia always gives military stations in 
geographical sequence, and not any how.” Granted then that the 
accuracy of the Notitia list has been so abundantly proved to be 
correct up to Amboglanna, it appears as though we might take it 
as a safe guide in fixing the remaining stations. Of course in this 
case there will be an undoubted difficulty, as there are more camps 
than there are available names, but that this difficulty is more 
apparent than real will appear as we proceed with our argument. 
We need scarcely ask to whom we owe the Notitia list. Clearly 
it is not a complete list of a/7 the camps on the Wall, or in its 
immediate vicinity. Why then are some admitted, and others 
omitted ? 
It must be remembered that when the Duke of Britain assumed 
the sole command, his forces were much less than his predecessors 
had, and this through the withdrawal of the 2oth legion. Conse- 
quently he would have to make the most of the reduced forces 
under his command, and that numerous changes took place in the 
various garrisons we may assume with a tolerable degree of certainty. 
If this be so, we have an additional element of uncertainty as to 
the altar test. 
Clearly there was no necessity that he should preserve to us in 
his list the name of every camp within his command—certain of 
them were of much greater importance to him than others—what 
then more natural than that he should select those most fitted for 
his wants, and that therefore the names of these places alone are 
preserved to us? That the majority of the changes would be on 
the western flank we have shown to be a fair subject for discussion. 
We ought, then, if we are to identify these places, to look upon 
the Notitia list as an exact skeleton, so to speak, of all the more 
important stations under the command of the Duke of Britain— 
important, so far as those not actually on the Wall itself are 
concerned, as strategic points; as opposed to mere, what we may 
term, way side stations. Such places would most certainly be
