Side 208 - They are not horns which have been shed ; for portions of the skull are found attached, proving that the whole animal perished. Bones of the ox, hog, horse, sheep, and other herbivorous animals, also occur ; and in Ireland, and the Isle of Man, skeletons of a gigantic elk ; but no remains have been met with belonging to those extinct quadrupeds of which the living congeners inhabit warmer latitudes , such as the elephant, rhinoceros, hippopotamus, hyena, and tiger, though these are so common in superficial...
