Page 38 - 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 133 - 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 55 - 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 278 - London water prevents the formation of any vegetable matter ; no vegetation can be detected, even by a microscope, after a long period. The Thames water has been examined from near its source to the metropolis, and an increasing amount of impurity detected. In the summary to this Report, Dr. Smith states that the pollution of air in crowded rooms is really owing to organic matter and not merely carbonic acid ; that all the water of great towns contains organic matter; that water purifies itself from...

Page 295 - The bowls are supplied with runners, which move horizontally ; in the center of these runners is an eye or opening, like that in the runner of a corn mill. The ground, or fine-stamped ore, gold, and water pass into this...
Page 297 - 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 110 - This period is recognized by the cultivators from the appearance of the leaves ; sometimes it occurs earlier than at others, and the collection of the manna takes place either at the beginning of July or only in August. Close to the soil cross sections are made in the stem, and in the lowermost sections small leaves are inserted, which conduct the sap into a receptacle formed by a cactus leaf; this is the way the manna in sorte is obtained.
Page 130 - The river gradually filled up the channel nearly bank high( while the living cataract travelled onward, much slower than I had expected to see it ; so slowly, indeed, that more than an hour after its first arrival the sweet music of the head of the flood was distinctly audible from my tent, as the murmur of waters and the diapason crash of logs travelled slowly through the tortuous windings of the river-bed.
