The only document I was able to consult was Lesquereux's "Report on the
Fossil Plants," in Hayden's report of 1872.
V-7. There is, at least, one instance so opportune to the present argument that it should not pass unnoticed, although I had overlooked the record until now. Onoclea sensibilis is a fern peculiar to the Atlantic United States (where it is common and wide-spread) and to Japan. Prof. Newberry identified it several years ago in a collection, obtained by Dr. Hayden, of miocene fossil plants of Dakota Territory, which is far beyond its present habitat. He moreover regards it as probably identical with a fossil specimen "described by the late Prof. E. Forbes, under the name of Filicites Hebridicus, and obtained by the Duke of Argyll from the island of Mull."

VI-2. Since this article was in type, noteworthy examples of appreciative scientific judgment of the derivative hypothesis have come to hand: 1. In the opening address to the Geological Section of the British Association, at its recent meeting, by its president, the veteran Phillips, perhaps the oldest surviving geologist after Lyell; and, 2. That of Prof. Allman, President of the Biological Section. The first touches the subject briefly, but in the way of favorable suggestion; the second is a full and discriminating exposition of the reasons which seem to assure at least the provisional acceptance of the hypothesis, as a guide in all biological studies, "a key to the order and hidden forces of the world of life."
