214 MR. E. W. BINNEY ON A FOSSIL PLANT 



XXVII. — Notice of a Fossil Plant found at Laxey, in the 

 Isle of Man. By E. W. Binney, F.R.S., F.G.S., 

 President. 



Bead January 22nd, 1878. 



Many years ago the late Sir William Logan drew attention 

 to the occuiTence of fossil plants in tlie Devonian strata of 

 Canada ; and Professor 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 spe- 

 cimens. 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 Professor Newbury 

 regarded 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. Professor 

 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 loth, 1877, has described and figured a plant from 

 the Lower Helderberg Sandstone, Michigan, under the 

 name oi Psilophytum cornutum. 



In a paper read by myself before this Society on the 26th 

 December, 1876, I stated that, after some years^ search, I 

 had not been able to find the Palaochorda major mentioned 

 by Professors Harkness and Nicholson as occurring in the 

 Manx schists, in such a state of preservation as to be certain 

 of its true nature, but I had a fucoid in my posession 

 found bv Mr. Grindlav in the drift near Laxev.
