II " It thus appears that, according to our present knowledge, the plant life of the land, so rich in the Coal formation, dies away rapidly in the Devonian, and only a few fragments attest Its existence in the Upper Silurian. Great interest thus attaches to these oldest remains of land plants; and fragmentary though they are, and often , they merit careful attention on the part of the geologist and botanist. " No locality hitherto explored appears more favourable to the study of this ancient vegetation than those parts of Eastern America to which this paper relates. The Gaspe sandstones have already afforded six Devonian species, some of them of great interest, and in a remark- ably perfect state of preservation; and from beds of similar age in New Brunswick and Maine, I am now prepai'cd to describe at least ten species, most of them new. This already raises the species found in the band of Devonian rocks, extending through the north-eastern States of the Union, and the eastern part of British America, to one- third of the number found in all other parts of the world; and the character of the containing rocks, the number of nondescript fragments, and the small amount of exploration hitherto made, justify the hope that a much larger number may yet be ; In the paper from which the above extract is taken, the total number of American Devonian species was raised to twenty-one, of which seven were from St John. Subsequently the much larger collections obtained at this place, farther collections by the writer at Perry, and specimens kindly placed at his disposal by Professor Hall of Albany and Sir William Logan, have raised the known species to eighty-two; and have t
