Abstract
PROF. COLE'S letter in NATURE of July 8, p. 39, concerning the earliest known rocks—a group of sediments—and their relation to the ortho-gneisses, will, I think, call forth the sympathy of students of African geology. In 1904–1905 I came to the conclusion that the para-schists of Southern Nigeria were older than at least the majority of the ortho-gneisses, and searched—without success—for the real foundation-stones which received upon their surface these earliest sediments.
