With these rocks, whether of Lake Huron, Newfoundland, or New llrnnswiek, l have no hesitation in comparing the I'ebidian of Wales, as well as certain portions of the older Malvern rocks and those of Charnwood Forest. Sonic of these groups 1 have seen on the ground, others are well known to me by suites of specimens. Similar rocks also succeed the Laurentian in Scandinavia and in other parts of Europe as well as in Africa and |)ortions of Asia. Thus the JIuronian typo is very widely distributed, even if we take it in the restricted sense as originally used by Logan, and, later, by Irving,J: and by the writer in lHr)7,§ and leave out doubtful deposits which liave been connected with it. 'l"he Huronian nnirks a period of igneous disturbance and coarse mechanical deposition succeeding to the Laurentian foldings. It is essentially a coastal or marginal deposit, and indicates that at the close of the Laurentian consi
