Side 83 - The intermixture of distinct species is guarded against by the aversion of the individuals composing them to sexual union, or by the sterility of the mule offspring. It does not appear that true hybrid races have ever been perpetuated for several generations, even by the assistance of man ; for the cases usually cited relate to the crossing of mules with individuals of pure species, and not to the intermixture of hybrid with hybrid.
Side 377 - Even before the trees form a wood, the real sea-birds nestle here; strayed landbirds take refuge in the bushes; and at a much later period, when the work has been long since completed, man also appears, builds his hut on the fruitful soil formed by the corruption of the leaves of the trees, and calls himself lord and proprietor of this new creation.

Side 71 - 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.
Side 265 - ... palustre) constitutes a considerable part of the peat found in marshes of the north of Europe ; this plant having the property of throwing up new shoots in its upper part, while its lower extremities are decaying. Reeds, rushes, and other aquatic plants may usually be traced in peat, and their organization is often so entire, that there is no difficulty in discriminating the distinct species.
Side 272 - In June, 1747, the body of a woman was found six feet deep, in a peatmoor in the Isle of Axholm, in Lincolnshire.
