Rh name kumbecephalic; and that after a time a brachycephalic people appeared on the scene, who, though still practising the simple methods of living prevalent in the Stone Age, were to some extent acquainted with the use of bronze.

Although Dr. Thurnam's aphorism, "long barrows, long skulls; round barrows, short skulls," is not strictly accurate, it undoubtedly conveys an important ethnological fact, which is thus stated by Professor Rolleston: "In no skull from any long barrow, that is to say, in no skull undoubtedly of the Stone Age, examined by us, has the breadth been found to bear so high a relation as that of 80:100 of the length." The more recent discoveries of human remains in the Oban caves, the chambered caves of Arran, and the Wick Barrow (Somersetshire) also lend support to the same view.
