30 psl. - The thrill of admiration which ran through the assembled thousands, when, at the commencement of his discourse on that occasion, Mr. Webster apostrophized the monument itself as the mute orator of the day, has been spoken of by those Who had the good fortune to be present as an emotion beyond the power of language to describe. The gesture, the look, the tone of the speaker, as he turned to the majestic shaft, seemed to invest it with a mysterious life; and men held their breath as if a solemn voice...
235 psl. - The result, therefore, of this physical inquiry is, that we find no vestige of a beginning, — no prospect of an end.
126 psl. - Smith, in consideration of his being a great original discoverer in English geology; and especially for his having been the first, in this country, to discover and to teach the identification of strata, and to determine their succession by means of their imbedded fossils...

Nothing can exceed it, unless that which Hannibal exhibited to his disconsolate troops when he bade them behold the glories of the Italian plains ! — If ever a turnpike road should lead through this country, I beg you will go and view this enchanting scene, though a journey of 40 miles is necessary for it. I never beheld anything equal to it in the West of England, that region of landscape ! ' This turnpike road,

Others assume the colour and texture of ordinary greenstone. Some of them are magnetic. Amongst the Cambrian sandstones they run in all directions, sometimes with, but more generally across, the strike. In the Silurian region they more generally run more or less parallel with the lines of bedding.
488 psl. - Of all the cursed roads that ever disgraced this kingdom in the very ages of barbarism, none ever equalled that from Billericay to the King's Head at Tilbury.
