Page 172 - Sweet are the uses of adversity ; Which, like a toad, ugly and venomous. Wears yet a precious jewel in his head.
Page 390 - Fear made her devils, and weak hope her gods ; Gods partial, changeful, passionate, unjust, Whose attributes were rage, revenge, or lust ; Such as the souls of cowards might conceive, And, form'd like tyrants, tyrants would believe.
Page 167 - ... strata will thus become crystallized by heat, and may eventually, with their included water, be raised to the melting point, by which process gases would be generated, and earthquakes and volcanic eruptions follow. At the same time the mechanical disturbance of the equilibrium of pressure, consequent upon a transfer of sediments, while the yielding surface reposes on matters partly liquefied, will explain the movements of elevation and subsidence of the earth's crust.
Page 168 - In order to obtain a correct notion of the condition of this mass, both in earlier and later times, two points must be especially considered, the relation of temperature to depth, and that of solubility to pressure.
Page 166 - Daubeny), but in known sedimentary formations, where they are the result of a peculiar kind of fermentation, which crystallizes and arranges in new forms the elements of the sedimentary strata, with an evolution of heat as a result of the chemical process. (Naturgeschichte, Vol. I. p. 109 ; also Bull. Soc. GeoL de France (1), Vol. VII. p. 197.) In commenting upon these views (Am. Jour. Science, July, 1860), I have remarked that, by ignoring the incandescent nucleus as a source of heat, Keferstein...
Page 172 - Fenton, who wrote in 1569, says — " There is to be found in the heads of •old and great toads a stone they call borax or stelon ;" and he adds — "They, being used as rings, give forewarning against venom.
Page 395 - Lawrence southward, during the paleozoic period, and chiefly, it would appear, during its earlier and later portions. This region is precisely that characterized by considerable eruptions of plutonic rocks during this period, and for some time after its close. To the westward of the Appalachians, the deposits...
Page 314 - The improvement, which is at first rapid, gradually, after a long series of years, is diminished in amount, and eventually so far arrested that, practically speakIng, a limit to improvement in the desired quality is reached. 7. By still continuing to select, the improvement is maintained and practically a fixed type is the result.
Page 309 - Turaco the existence of the red colouring matter which belongs to their normal plumage is dependent upon copper, which, obtained in minute quantities with the food, is stored up in this strange manner in the system of the animal. Thus in the very same feather, partly red and partly black, copper was found in abundance in the red parts, but none or only the merest trace in the black. This example warns us against taking too utilitarian a view of the plan of creation. Here we have a chemical substance...
Page 308 - ... discoveries which from time to time stamp their impress on different branches of science. I may be permitted to refer to one or two discoveries which are exceedingly curious, and some of which may prove of considerable practical importance. The Turaco or plantain-eater of the Cape of Good Hope is celebrated for its beautiful plumage.
