Page 112 - Every river appears to consist of a main trunk, fed from a variety of branches, each running in a valley proportioned to its size, and all of them together forming a system of valleys, communicating with one another, and having such a nice adjustment of their declivities, that none of them join the principal valley, either on too high or too low a level...
Page lxix - ... dignity over all the society in which he moved. The same admirable taste which is conspicuous in his writings, or rather the higher principles from which that taste was but an emanation, spread a similar charm over his whole life and conversation ; and gave to the most learned philosopher of his day the manners and deportment of the most perfect gentleman.
Page lxvi - His chief effort and greatest pleasure was in their revisal and correction ; and there were no limits to the improvement which resulted from this application. It was not the style merely, or indeed chiefly, that gained by it. The whole reasoning, and sentiment, and illustration, were enlarged and new modelled in the course of it, and a naked outline became gradually informed with life, colour, and expression.

Page xcii - By and bye, to any one that is stationed on the side, even to those at a great distance, the same is announced by the roaring of the tree itself, which becomes always louder and louder ; the tree comes in sight when it is perhaps half a mile distant, and in an instant after shoots past, with the noise of thunder and the rapidity of lightning.
Page 114 - ... occasionally, that is, when they are flooded or swollen with rains. The quantity of earth thus carried down varies according to circumstances : it has been computed in some instances, that the water of a river in a flood, contains earthy matter suspended in it, amounting to more than the two hundred and fiftieth part of its own bulk.
Page 121 - Oreologist would trace back the progress of waste, till he come in sight of that original structure, of which the remains are still so vast, he perceives an immense mass of solid rock, naked and unshapely, as it first emerged from the deep, and incomparably greater than all that is now before him. The operation of rains and torrents...
