Note 357 — Chapter V

See L. Wray's paper "On the Cave Dwellers of Perak," in Jour. Anthrop. Inst. 1897, p. 36 sq. This observer thinks "the earliest cave dwellers were most likely the Negritoes" (p. 47), and the great age of the deposits is shown by the fact that "in some of the caves at least 12 feet of a mixture of shells, bones, and earth has been accumulated and subsequently removed again in the floors of the caves. In places two or three layers of solid stalagmite have been formed and removed, some of these layers having been five feet in thickness" (p. 45).
