Rozier says, in his ‘Journal de Physique,’ 1782, page 174, that “mention is made in the Catalogue of Davila of a tibia and of a beak imprinted on two different stones.” If there be any other notice in Davila than the passages we have quoted, it has escaped our search.In 1782, M. Robert de Paul de Lamanon gave, in the Abbé Rozier's ‘Journal de Physique’ (vol. xx. p. 174), an excellent summary of what was then known of Ornithic fossils. After noticing the accounts in Albertus Magnus and other old authors, he goes onto say in his ‘Description de Divers Fossiles trouvés dans les carrières de Montmartre, près Paris, et vues générales sur la formation des Pierres gypseuses,' “M. Rouelle, according to M. Darcet, found in the plaster quarries of Montmartre parts of a bird separated one from the other. I(Lamanon) have seen also in the Cabinet of Natural History of Bordeaux, some bones that it has been attempted to refer to birds; they were found by the Abbé Desbiey in the quarries of Léognan, which are at two leagues from this capital. We can only assert, however, that these isolated bones may have belonged to birds, on the ground that their medullary cavity is very large relatively to their thickness.
