As a general rule the Germanic, or Gothic, stock has not only held its own area from the earliest time, but has encroached on that of others, so that although there are many parts of Europe, which, once the occupancy of non-Germanic populations, have now become more or less German, the converse rarely, if ever, can be shown to have taken place. Hence, almost all the districts which were originally German, are German now. The chief exception, if it be one, occurs in Belgium, where the Gallo-Roman family, has, _perhaps_, encroached on the Gothic. But, though the Old Germany be Germanic still, there is a great part of the Modern Germany which was not so even at the beginning of the historical period. Some portion of the present area was Keltic, and a still greater was Sarmatian. Besides which, the original population of no inconsiderable section is uncertain. All this somewhat reduces the simplicity of the ethnology. And to this, it must be added, that the Teutonic (or German) branch of the great Gothic stock falls into some important divisions. The Frisians of Friesland represent one of these, our Anglo-Saxon ancestors another, the Old Saxons of Westphalia a third, the Low Dutch of Holland a fourth, the High Dutch of Bavaria a fifth, the Goths of the Old Ostrogoth and Visigoth conquests a sixth. Now the intestine movements of these different divisions have always been great; so that, although we shall rarely hear of any Germanic population having been overlaid by Slavonians or Kelts, the phenomenon of Saxons superseded by Low Dutch, Low Dutch by High and other similar displacements will be common. The divisions, then, of the Germanic area are as follows:-- 1st. There is the pure and proper country of the indigenous Germans, wherein all the important elements of admixture are limited to the different divisions and subdivisions of the Germanic family. 2nd. There is the area which was originally Sarmatian falling into-- _a._ The Lithuanic, and-- _b._ The Slavonic districts. 3rd. There is the tract which was originally Keltic. 4th. The parts whose original ethnology is uncertain. The details of the different political divisions supply us with the commentary on this classification. _Prussia._--The kingdom of Prussia well illustrates the difficulty of making ethnology and politics agree. It falls into two parts separated from each other. Of these the first, with the possible exception of its south-western corner, was wholly Sarmatian in the tenth century; as Sarmatian as England was Keltic, or Spain Iberic. The population, too, was referable to both branches of the Sarmatian stock--the Slavonic as well as the Lithuanic.
