This paper is intended as preliminary to one shortly to follow on the nature and origin of the banded structure in these rocks. I have deemed it necessary to treat of the present subject as introductory to the other, giving my own views as to what I believe to be the true origin and relations of these rocks to each other, as these seemed to me to have a very direct and important bearing on the question of their banded structures.
