Seite 37 - O'er bog, or steep, through strait, rough, dense, or rare, With head, hands, wings, or feet, pursues his way, And swims, or sinks, or wades, or creeps, or flies.
Seite 57 - Plesiosaurus that Cuvier asserts the structure to have been the most heteroclite, and its characters altogether the most monstrous that have been yet found amid the ruins of a former world. To the head of a lizard it united the teeth of a crocodile, a neck of enormous length, resembling the body of a serpent, a trunk and tail having the proportions of an ordinary quadruped, the ribs of a cameleon, and the paddles of a whale.
Seite 19 - Although no skeleton has been found entire, so many perfect bones and teeth have been discovered in the same quarries, that we are nearly as well acquainted with the form and dimensions of the limbs as if they had been found together in a single block of stone.
Seite 57 - Such are the strange combinations of form and structure in the Plesiosaurus — a genus, the remains of which, after interment for thousands of years amidst the wreck of millions of extinct inhabitants of the ancient earth, are at length recalled to light by the reseaches of the Geologist, and submitted to our examination, in nearly as perfect a state as the bones of species that are now existing upon the earth.

The hind paddles would also be serviceable in terrestrial progression as...
Seite vi - From a succession of such shiftings of the situation of the sea we may have a stratum of marine extraneous fossils, one of earth, mixed probably with vegetables and bones of land animals, a stratum of terrestrial extraneous fossils, then one of marine productions; but from the sea carrying its inhabitants along with it, wherever there are those of land animals there will also be a mixture of marine ones; and from the sea commonly remaining thousands of years in nearly the same situation, we have...
Seite 33 - Among the specimens lately collected, some, however, were so perfect, that I resolved to avail myself of the obliging offer of Mr. Clift (to whose kindness and liberality I hold myself particularly indebted), to assist me in comparing the fossil teeth with those of the recent Lacertae in the Museum of the Royal College of Surgeons. The result of this examination proved highly satisfactory, for in an Iguana which Mr. Stutchbury had prepared to present to the College, we discovered teeth possessing...
Seite 122 - Cheirotherium (cheir, the hand, therion, beast) for the 1mknown animal that had left the footprints, in consequence of the resemblance, both of the fore and hind feet, to the impression of a human hand ; and Dr. Kaup conjectured that the animal might be a large species of the opossum kind ; but in Didelphys the thumb is on the inner side of the hind-foot.
