Présentation de l'éditeur
A palachian coal-field, upon which the accompanying series of investigations was made, formed a part of a collection of Professor Ferdinand Romer, which, after his return from a scientific tour in North A merica, he deposited in the paleontological cabinet of the Berlin University. Unfortunately, the notes pertaining to the immediate localities of these fossil impressions, are no longer to be found; but, with the exception of three species of Lepidodendra from the Ohio coal-field, it is certain that they are from the state of Pennsylvania. The matrix of the Ohio specimens is argillaceous sandstone, while that of the Pennsylvania fossils is of hard, bluish black, argillaceous slate.
