Page 332 - ... correct conduct of the present sheep farmers have operated to produce a correspondent change in the character of their servants. The shepherds in Kidland are peculiarly attached to their dogs ; and not without reason, for the sagacity, activity, and discrimination of these animals, are truly surprising, and would scarcely be credited by those who have not had an opportunity of observing their actions. On setting out in a morning, the dog, without receiving any instructions, takes a round to scour...
Page 37 - During violent gales of wind, hundreds of tons of them are often thrown up together in beds on the flat beaches, the decay of which spreads an intolerable effluvium around. It is made no use of, except for bait ; and as it maintains itself in deeper water than the...
Page 368 - The other substances met with are no less corrobprative of the cause assigned. Great quantities of asphaltum appear floating on the surface of the sea, and are driven by the winds to the east and west bank, where they remain fixed.
Page 60 - I found that almost all bodies in which the combustion was imperfect, such as paper, linen, cotton, $c. gave a light in which the homogeneous yellow rays predominated ; — that the quantity of yellow light increased with the humidity of these bodies ; — and that a great proportion of the same light was generated, when various flames were urged mechanically by a blowpipe or a pair of bellows.
Page 235 - These results are best explained by considering the nature of the flame of combustible bodies, which, in all cases, must be considered as the combustion of an explosive mixture of inflammable gas, or vapour and air...
Page 158 - ... itself in its full splendour. It can be proved mathematically, that the rays of the northern lights ascend from the surface of the earth, in a direction inclining towards the...
Page 390 - The extreme facility with •which sounds are heard at a considerable distance, in severely cold weather, has often been a subject of remark ; but a circumstance occurred at Port Bo wen, which deserves to be noticed, as affording a sort of measure of this facility.
Page 370 - The valley of Ghor is continued to the south of the Dead Sea ; at about sixteen hours' distance from the extremity of the Dead Sea its name is changed into that of Araba, and it runs in almost a straight line, declining somewhat to the west as far as Akaba, at the extremity of the eastern branch of the Red Sea. The existence of this valley appears to have been unknown to ancient as well as...
Page 372 - Who said to God, depart from us, What can Shaddai do to us ? Though he had filled their houses with wealth. (Far from me be the counsel of the wicked !) The righteous beheld and rejoiced, The innocent laughed them to scorn : Surely their substance was carried away, And their riches devoured by fire.
Page 112 - The piston is then raised, and the air which occupied the barrel is forced out through the aperture at E. The point of one of the fingers is applied to the perforation, in the same manner as in playing the German flute. The air easily passes by the finger, which, when the piston begins to descend, shuts the opening, and completely prevents the entrance of the external air. The piston is again forced down below the opening C, the air in the receiver rushes into the barrel, and is again expelled by...
