Abstract
MANY years ago the late Sir William Logan drew attention to the occurrence of fossil plants in the Devonian strata of Canada, and Prof. J. W. Dawson, F.R.S., in the Quarterly Journal of the Geological Society, in vols. xv. and xviii., described and figured some of these specimens. Amongst them was a plant which he designated Psilophytum. Dr. S. S. Scoville has since discovered the remains of plants in the lower Silurians at Longstreet Creek, near Lebanon, Ohio, which Prof. Newberry considered as the casts of some large fucoids or marine plants. Count Saporta has found the branch of a fern in the Silurian schists or slates of Angers, France. Prof. Leo Lesquereux, to whom we owe so much for his labours in investigating the fossil plants of the United States, in a paper read before the American Philosophical Society, October 10, 1877, has described and figured a plant from the lower Heldeberg sandstone, Michigan, under the name of Psilophytum cornutum.
