Página 6 - Full little knowest thou, that hast not tried, What hell it is in suing long to bide ; To lose good days that might be better spent ; To waste long nights in pensive discontent; To speed to-day, to be put back to-morrow ; To feed on hope ; to pine with fear and sorrow ; To have thy Prince's grace, yet want her peers...
Página 9 - Anon out of the earth a fabric huge Rose, like an exhalation, with the sound Of dulcet symphonies and voices sweet, Built like a temple, where pilasters round Were set, and Doric pillars overlaid With golden architrave ; nor did there want Cornice or frieze with bossy sculptures graven ; The roof was fretted gold.
Página 492 - Let the hurricane tear up its thousand huge fragments ; yet what will that tell against the accumulated labour of myriads of architects at work night and day, month after month ? Thus do we see the soft and gelatinous body of a polypus, through the agency of the vital laws, conquering the great mechanical power of the waves of an ocean which neither the art of man nor the inanimate works of nature could successfully resist.
Página 409 - I have sometimes imagined that a disturbed electrical condition of the atmosphere was most favourable to its production. Certainly I think the sea is most luminous after a few days of more calm weather than ordinary, during which time it has swarmed with various animals. Observing that the water charged with gelatinous particles is in an impure state, and that the luminous appearance in all common cases is produced by the agitation of the fluid in contact with the atmosphere, I am inclined to consider...
Página 188 - Arve and Arveiron at thy base Rave ceaselessly; but thou, most awful Form, Risest from forth thy silent sea of pines How silently! Around thee and above, Deep is the air and dark, substantial, black — An ebon mass.
Página 450 - Aided by the winds and waves, it undermines and sweeps away the granite, gneiss, trap rocks, and sand-stone of Shetland, and removes the gravel and loam of the cliffs of Holderness, Norfolk, and Suffolk, which are between fifty and two hundred feet in height, and which waste at the rate of from one to six yards annually. It also bears away, in co-operation with ie Thames and the tides, the strata of London clay on the const of Essex and Sheppey.
Página 446 - But the most sublime scene is where a mural pile of porphyry, escaping the process of disintegration that is devastating the coast, appears to have been left as a sort of rampart against the inroads of the ocean ; the Atlantic, when provoked by wintry gales, batters against it with all the force of real artillery, the waves having, in their repeated assaults, forced themselves an entrance.
Página 478 - I will here add a few other observations connected with the discoloration of the sea from organic causes. On the coast of Chile, a few leagues north of Concepcion, the "Beagle" one day passed through great bands of muddy water, exactly like that of a swollen river; and again, a degree south of Valparaiso, when fifty miles from the land, the same appearance was still more extensive.
Página 460 - Viewing these tribes in the most careless way, as a system of subaqueous vegetation, or even in a merely picturesque light, we see the depths of the ocean shadowed with submarine groves, often of vast extent, intermixed with meadows, as it were, of the most lively hues; while the trunks of the larger species, like the giant trees of the tropics, are loaded with innumerable minute kinds as fine as silk or transparent as a membrane.
Página 392 - ... sixty to eighty miles from the western shores of England, contains only 35'7 parts of solid substances ; and the same quantity of salt is found all over the north-eastern part of the Atlantic as far to the north as Iceland, always at such a distance from the land that the influence of fresh water from the land is avoided.
