Scotland, like Ireland, is _Gaelic_ in respect to its Keltic population, but the stock is less pure. However slight may be the admixture of English blood in the Highlands and the Western Isles, the infusion of Scandinavian is very considerable. Caithness has numerous geographical terms whose meaning is to be found in the Danish, Swedish, Norwegian, and Icelandic. _Sutherland_ shews its political relations by its name. It is the _Southern Land_; an impossible name if the county be considered English (for it lies in the very _north_ of the island), but a natural name if we refer it to Norway, of which Sutherland was, at one time, a southern dependency, or (if not a dependency), a robbing-ground. Orkney and Shetland were once as thoroughly Norse as the Faroe Isles or Iceland. The third variety of the present British population is in the Isle of Man, where a language sufficiently like the Gaelic of Ireland and Scotland to be placed in the same division, is still spoken. Yet the blood is mixed. The Norsemen preponderated in Man; and the constitution of the island is in many parts Scandinavian, though the language be Keltic. In Wales the language and population are still Keltic, though sufficiently different from the Scotch, Irish, and Manx, to be considered as a separate branch of that stock. It is conveniently called _British_, _Cambrian_, and _Cambro-Briton_. It is quite unintelligible to any Gael. Neither can any Gael, talking Gaelic, make himself understood by a Briton. On the other hand, however, a Scotch and an Irish Gael understand each other; whilst, with some effort, they understand a Manxman, and _vice versâ_. So that the number of mutually unintelligible languages of the Keltic stock is two; in other words, the Keltic dialects of the British Isles are referable to two branches--the British for the Welsh, and the Gaelic for the Scotch, Irish, and Manx. The other language of the British Isles is the English, one upon which it is unnecessary to enlarge; but which makes the third tongue in actual existence at the present moment, if we count the Irish, Scotch, and Manx as dialects of the same language, and the fifth if we separate them.
