Page 202 - Thus, in Mar forest, in Aberdeenshire, large trunks of Scotch fir, which had fallen from age and decay, were soon immured in peat, formed partly out of their perishing leaves and branches, and in part from the growth of other plants. We also learn, that the overthrow of a forest by a storm, about the middle of the seventeenth century, gave rise to a peat moss near Lochbroom, in Ross-shire, where^ in less than half a century after the fall of the trees, the inhabitants dug peat.* Dr.
Page 46 - If, therefore, the relative fecundity or hardiness of hybrids be in the least degree inferior, they cannot maintain their footing for many generations, even if they were ever produced beyond one generation in a wild state. In the universal struggle for existence, the right of the strongest eventually prevails; and the strength and durability of a race depends mainly on its prolificness, in which hybrids are acknowledged to be deficient.

Page 14 - We must suppose that when the author of nature creates an animal or a plant, all the possible circumstances in which its descendants are destined to live are foreseen, and that an organization is conferred upon it which will enable the species to perpetuate itself, and survive under all the varying circumstances to which it must be inevitably exposed.
Page 53 - If you examine the brain of the mammalia, says M. Serres, at an early stage of uterine life, you perceive the cerebral hemispheres consolidated, as in fish, in two vesicles, isolated one from the other ; at a later period, you see them affect the configuration of the cerebral hemispheres of reptiles ; still later again, they present you with the forms of those of birds ; finally, they acquire, at the era of birth, and sometimes later, the permanent forms which the adult mammalia present.
Page 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...
