"Ornithichnites of the Connecticut River Sandstones and the Dinornis of New Zealand" contains several notable items: the 1842 letter James Deane wrote to Gideon Mantell when he sent him fossil footmarks to examine; Dr. Mantell's reply about his presentation of Deane's tracks to the Geological Society of London and the ensuing discussion about whether the tracks were made by birds or reptiles. Following is a letter from Professor Richard Owen to Benjamin Silliman about the Dinornis of New Zealand and its similarities to the Connecticut River Valley footprints. The article ends with an address given in February 1843 by the Society's president, Roderick Murchison, with a follow-up of the society's thoughts since Mantell's presentation of Deane's tracks.
