Note 3 — STROMNESS AND ITS ASTEROLEPIS. THE LAKE OF STENNIS.

Since the above sentence was written and set in type, I have learned that my ingenious friend, Mr. Charles Peach of the Customs, Fowey, so well known for his palæontological discoveries, has just found in the Devonian system of Cornwall, fragments of what seem to be dermal plates of Asterolepis. It is a somewhat curious circumstance, that the two farthest removed extremities of Great Britain—Cornwall and Caithness—should be tipped by fossiliferous deposits of the same ancient system, and that organisms which, when they lived, were contemporary, should be found embedded in the rocks which rise over the British Channel on the one extremity, and overhang the Pentland Frith on the other.
