According to Dr. Joseph Anderson, although of Pagan origin, the fylfot has become a Christian symbol from the fourth to the fourteenth or fifteenth century.--(_Scotland in Early Christian Times_, vol. ii. p. 218.) It is seen also in a mosaic pavement in the recently explored Roman villa in the Isle of Wight.

SUBSEQUENT RESEARCHES AND DISCOVERIES AT FRIARS' CARSE, LOCHSPOUTS, BARHAPPLE, AND BUSTON. Before the interesting series of objects obtained from the excavation of the Lochlee crannog, and described in the previous chapter, could be properly illustrated and efficiently brought under the notice of antiquaries, other promising "finds" of a similar nature were announced from various quarters. All these have now, as far as practicable, been carefully investigated, with results, in some respects, even more remarkable than the former. To a description of these further excavations and discoveries I propose to devote this chapter, commencing with that of a lake-dwelling at Friars' Carse, in Dumfriesshire, and following it up by others in the order of their discovery.
