Chichester, which it attributes to the mythical South Saxon king Cissa. Whatever Cissanceaster may mean, it seems to me much more likely that it represents another case of double naming; for though the Roman town was commonly known as Regnum, that is clearly a mere administrative form, derived from the tribal name of the Regni. Considering that the same veracious _Chronicle_ derives Portsmouth, the Roman Portus, from an imaginary Teutonic invader, Port, and commits itself to other wild statements of the same sort, I don't think we need greatly hesitate about rejecting its authority in these earlier and conjectural portions. Silchester is another much disputed name. As a rule, the site has been identified with that of Calleva Atrebatum; but the proofs are scanty, and the identification must be regarded as a doubtful one. I have already ventured to suggest that the word may contain the root Silva, as the town is situated close upon the ancient borders of Pamber Forest. The absence of early forms, however, makes this somewhat of a random shot. Indeed, it is difficult to arrive at any definite conclusions in these cases, except by patiently following up the name from first to last, through all its variations, corruptions, and mis-spellings. The _Cesters_ are even more degraded (philologically speaking) than the _Chesters_, but are not less interesting and illustrative in their way. Their farthest northeasterly extension, I believe, is to be found at Leicester and Towcester. The former we have already considered: the latter appears in the _Chronicle_ as Tofe ceaster, and derives its name from the little river Towe, on which it is situated. Anciently, no doubt, the river was called Tofe or Tofi, like the Tavy in Devonshire; for all these river-words recur over and over again, both in England and on the Continent. In this case, there seems no immediate connection with the Roman name, if the site be rightly identified with that of Lactodorum; but at any rate the river name is Celtic, so that Towcester cannot be claimed as a Teutonic settlement.
