Sivu 48 - Professor Owen's Lectures on the Comparative Anatomy and Physiology of the Vertebrate Animals, delivered at the Royal College of Surgeons in 1844 and 1846.
Sivu 363 - ... above the outline of the shell; posterior portion a little longer; sulcations coarse, regular; epidermis dark chestnut brown; interior light blue; hinge margin narrow, nearly a straight line; cardinal teeth small, indistinct, situated somewhat towards the anterior side, double in both valves, and so placed as to assume the shape of the letter V reversed; lateral teeth on a line with the primary teeth, large, strong and prominent.
Sivu 209 - The most successful method of obtaining them Is to take such a position as they will probably fly over in passing from one feeding ground to another. They may then be shot with ease, as they rarely fly high at such times. The pertinacity with which they cling to certain feeding grounds, even when much molested, I saw strikingly illustrated on one occasion. The tide was rising and about to flood a muddy flat of perhaps an acre in extent, where their favorite snails were in great quantities. Although...

There seems to have been a general reluctance on the part of each of these companies to take the lead in seeking a cut; it was probably believed that a reduction would cause more difficulties than...
Sivu 468 - Description of new species of Cretaceous fossils from New Jersey, Alabama, and Mississippi: Acad.
Sivu 380 - Although we still retain this as a distinct rock, our present impression is, that it is probably only a subdivision or member of the Fort Benton Group. Still, until more fossils can be obtained from it in the region of the typical localities, the question whether or not it should rank as a distinct formation must remain an open onr. That it is at least as old as the Fort Benton Group...
