Page 42 - Seeing every height crowned with its crater, and the boundaries of most of the lava-streams still distinct, we are led to believe that within a period, geologically recent, the unbroken ocean was here spread out. Hence, both in space and time, we seem to be brought somewhat near to that great fact — that mystery of mysteries — the first appearance of new beings on this earth.
Page 137 - In 1 Vol., price 5s. THE SPORTING WORLD, BY HARRY HIEOVER. " Reading Harry Hieover's book is like listening lazily and luxuriously after dinner to a quiet, gentlemanlike, clever talker.
Page 19 - ... and the crashing of the ice, fell upon the ear with fearful distinctness ; whilst the frequently averted eye as immediately returned to contemplate the awful destruction that threatened in one short hour to close the world and all its hopes and joys and sorrows upon us for ever. In this our deep distress, we called upon the Lord, and he heard our voices out of his temple, and our cry came before him.
Page 59 - It is of a melancholy visage, as sensible of nature's injury in framing so massie a body to be directed by complimental wings, such, indeed, as are unable to hoise her from the ground, serving only to rank her among birds. Her traine, three small plumes, short and improportionable, her legs suiting to her body, her pounces sharpe, her appetite strong and greedy.
Page 59 - I will name but some, and first, the Dodo ; a Bird the Dutch call Walghvogel or Dod Ersen : her body is round and fat which occasions the slow pace or that her corpulencie ; and so great as few of them weigh less than fifty pound : meat it is with some, but better to the eye than stomach ; such as only a strong appetite can vanquish...
Page 132 - Khan. Part of the force was at that moment in hot pursuit, or the ruin would have been wider. The rest ran, some to large trees, which were all soon uprooted and borne away ; others to rocks, which were speedily buried beneath the waters. Only they escaped who took at once to the mountain side. About 500 of these troops were at once swept to destruction.

Sublime and magnificent as such a scene must have appeared under different circumstances, to us it was awful, if not appalling. For eight hours we had been gradually drifting towards what to human eyes appeared inevitable destruction; the high waves and deep rolling of our ships rendered towing with the boats impossible, and our situation the more painful and embarrassing from our inability to make any effort to avoid...
Page 301 - The mould around the plants and an infusion of the dead stems and leaves also afforded abundant evidence of the presence of much chloride of sodium. Further inquiry showed that the well from which the water was procured had an accidental communication, by means of a drain, with the sea; and had thus become mixed with the salt water from that source, and had been used in this state for some weeks, probably from two to three months. From about that time the plants had been observed to droop ; but it...
Page 103 - One of Pliny's sentences is remarkable as narrating a class experiment fit for a chemical school : Plumbi albi experimentum in charta est, ut liquefactum pondere videatur, non calore, rupisse. The meaning seems to be, that the metal is fluid at so moderate a heat as when fused to break by its weight, not burn by its heat the charta on which it is poured. Tin melts at 440°— 442° ; Lead at 612°. What follows is a very important passage : India neque ses neque plumbum habet, gemmisque suis ac margaritis...
