BY JOHN C. WARREN, M.D. PRESIDENT OF THE BOSTON SOCIETY OF NATURAL HISTORY. [Illustration: Logo] BOSTON: TICKNOR AND FIELDS, 135, Washington Street. 1854. BOSTON: PRINTED BY JOHN WILSON AND SON, 22, School Street. The principal part of these remarks were made at the meetings of the BOSTON SOCIETY OF NATURAL HISTORY. A portion of them also have been printed in the Proceedings of the Society. The object of this publication is to afford to those who are not members of the Society an opportunity of obtaining some knowledge of Fossil Impressions, which they might not be able to obtain elsewhere so conveniently. Some account of the Epyornis seems to be very properly connected with Ornithichnites. The first of these papers was written in October, 1853; the others in the earlier part of the present year. [Illustration: Epyornis] THE EPYORNIS; OR, GREAT BIRD OF MADAGASCAR, AND ITS EGGS. In the course of the year 1851, an account was circulated of the discovery of an immense egg, or eggs, in the Island of Madagascar. The size of the eggs spoken of was so disproportionate to that of any previously known, that most persons received the account with incredulity; and, I must confess, I was one of this number. Being in Paris soon after hearing of this report, I made inquiry on the subject, and was surprised to learn, that the great egg was actually existing in the Museum of Natural History in Paris. In a few days I had an opportunity of seeing a cast of it in the hands of the artist, M. Strahl, of whom I solicited one. He informed me that it could not be obtained at that moment; but that, if my request were made known to the Administration of the Museum, he had no doubt they would accede to it. I accordingly did apply, and also presented them with the cast of a perfect head of Mastodon Giganteus; and they very liberally granted my request.
