Página 19 - The excavation of vallies can be ascribed to no other cause than a great flood of water which overtopped the hills, from whose summits those vallies descend.
Página xvi - Enough, if something from our hands have power To live, and act, and serve the future hour; And if, as toward the silent tomb we go, Through love, through hope, and faith's transcendent dower, We feel that we are greater than we know.
Página 50 - The alterations in the form of land, occasioned by diluvial agency, must have been considerable, but are not yet well understood; the operation of natural causes since that period deserves to be maturely considered, for these have materially changed the face of the globe. The lakes which were left, on the retiring of the diluvial currents, appear to have been continually diminished in depth, and contracted in extent, by deposits of vegetable matter, decayed shells, and sediment brought into them...
Página 117 - the interesting remains of Spongiae are nowhere so well developed as in England, and perhaps nowhere in England, so well as in Yorkshire. On the shore near Bridlington, they lie exposed in the cliffs and scars, and being seldom enclosed in flint, allow their organization to be studied with the greatest advantage.
Página 46 - Yorkshire, is composed of a base of clay, containing fragments of pre-existing rocks, varying in roundness and size. The rocks from which the fragments appear to have been transported are found, some in Norway...
Página 154 - in the midland counties, the Fuller's earth rock of Mr. Smith does by no means furnish a constant or wellmarked line of distinction between the middle (great or Bath) oolite and the inferior oolite ; and I am decidedly of opinion, that in the northern part of Northamptonshire, and throughout Rutland and Lincolnshire, there is but one thick oolitic rock beneath the cornbrash, resting upon brown sandstone, which immediately covers the upper lias shale.

Página 151 - Sternberg. and mountain limestone" — in other words, is associated with the more ancient carboniferous deposits. " A cursory observer," adds Mr. Phillips, " may, perhaps, be led to confound together the ferns and calamites of the coal district with the ferns and equiseta of the oolitic rocks : though to a botanical eye their difference is very apparent : but who can mistake the lepidodendra of the former, the cycadiform fronds of the middle period, and the dicotyledonous leaves and fruits which...
