That this word _Vithesleth_ is a compound, that its first element is a Gentile name, and that the population which bore it was other than the modern Danes will be suggested in the sequel. At present it is enough to remember that the existing population of the four eastern islands is Germanic on a hitherto unvestigated basis. The men of the _Vith_-es-leth it is convenient to call _Vitæ_. In Fyen the Gothic elements are the same as in the Vithesleth, the _differentiæ_ consisting in the difference of the original basis, provided that such existed. This may or may not have been the case; since it by no means follows that because the islands of the Vithesleth differed from Fyen, that difference was ethnological. It may have been only political. _Lauenburg._--In the tenth century Lauenburg is Slavonic; its occupants being a population called _Po-labi_; called also _Po_-lab-ingii. As _po_ means _on_, and _Laba_ is the Slavonic form for the _Elbe_, the name is a compound, like _Pomerania_ (_on the sea_). The _Polabi_, then, were the Slavonians of the Elbe. They were an extreme population; since the river Bille divided them from the Germans of Stormar, Holstein, and Ditmarsh. But though the _Polabi_ of Lauenburg were a frontier population they were not isolated. They were in geographical continuity with the Linones of Luneburg, and the Obotrites of Mecklenburg. Reduced by the Carlovingian Franks, Lauenburg became Low German; as it is at the present time. _Holstein._--The name of the duchy is German, and derived from a German population--the _Holsati_. But the Holsati were neither the only occupants, nor the only Germans of these parts. The Stormarii of Stormar, and the Dietmarsi of Ditmarsh are equally mentioned by the writers of the eighth century. Earlier still we hear of the Sabalingii and Sigulones. The Holsati, Dietmarsi, and Stormarii, were either Angles or Frisians. So much for the western half of the duchy. The eastern was Slavonic; even as Lauenburg was Slavonic, the particular population being that of the _Wagri_. They are a frontier population; and this may, _possibly_, be denoted by the name, which contains the same elements as that of the _Ucri_ of _Ucker_mark, and the Malorussians of the _Ukr_aine. _Sleswick._--With Slavonians on the Baltic, and Frisians on the Atlantic, the original ethnology of Sleswick seems to have been that of the sister duchy. In Sleswick, however, the Frisian population still exists, extended from Husum to Tondern. In Sleswick also we have a portion of the Jute population of Jutland. _Jutland._--If the combination, _J_+_t_ as it occurs in the word _Jute_, being the same as the _G_+_t_ in _Got_, or _Goth_, we have a reason in favour of one of its earlier populations having been Lithuanic. Then we have the Slavonians of Holstein and Sleswick to the south. How far these extended northwards is uncertain. Between the two, however, I believe that eastern Jutland, at least, was Sarmatian before it was German.
