الصفحة 140 - I might here observe, that the British Government would confer a lasting blessing on the Assamese and the new settlers, if immediate and active measures were taken to put down the cultivation of opium in Assam, and afterwards to stop its importation by levying high duties on opium land.
الصفحة 387 - Shaw moreover observes, that, if the parr were a distinct species, the results of their attendance on the female salmon would produce universal confusion among the migratory inhabitants of rivers, " from the circumstance of the male parrs, in a breeding state, occupying in great numbers the very centre of the salmon spawning-bed ; while the female salmon herself is, at the same instant, pouring thousands of her ova into the very spot where they are thus genially congregated.
الصفحة 69 - As you approach the lagoons, the earth seems to pour out boiling water as if from volcanoes of various sizes, in a variety of soil, but principally of chalk and sand.
الصفحة 317 - ... bell-glass which cut off all communication between the air of the apartment and that of the plant, the heat of the latter always rose suddenly some tenths of a degree. This phenomenon, however, lasted only a few minutes; the magnetic needle soon retrograded, passing zero of the scale, and showing, by its opposite and permanent deviation, that the living plant had a much lower temperature than the dead leaf, as is always the case in the atmosphere. " Is this phenomenon to be ascribed to the instantaneous...
الصفحة 390 - It was stated, that, in the acrid species of the genera Ranunculus, Anemone, and Clematis, the acridity, which is the same throughout them all in quality, is possessed in nearly equal activity by the leaves, from an early period in the spring until they are about to decay ; but that it exists in the germens only while they are green, and disappears there entirely as the seeds ripen. In the acrid species of...
الصفحة 390 - Aconitum, the acridity of the leaves, on the contrary, continues only until the seeds begin to form, and then gradually, but quickly, disappears as they ripen, while the seeds acquire precisely the same peculiar kind of acridity. The narcotic properties of the leaves, however, do not undergo the same singular change, but continue undiminished after the seeds are mostly ripe, and probably, indeed, as long as the leaves themselves retain their freshness. The acridity of the genus Helleborus is probably...
الصفحة 277 - ... that a black scale remains after hardening, which it is difficult to remove without some injury to the work, as in the case of a screw tap ; whereas, if the same piece of steel be heated in a flame of the mixed gases, where there is no free oxygen to attack its surface, it may be made and kept red hot without any injury to its finest edge; it will be discoloured, but without losing much of its polish. The artist has also the advantage of a distinct view of the article while it is being heated,...
الصفحة 188 - London, gentleman, in consequence of a communication made to him by a certain foreigner residing abroad, for an invention for producing motive power, which he denominates a self-acting motive power, and called in France by the inventor
الصفحة 119 - This pan is fixed in masonry breast high, and in a sloping position, forming an angle of forty degrees. Thus the pan being placed on an inclined plane, the leaves when tossed about in it cannot escape behind, or on the sides, as it is built high up. but fall out near the edge close to the manufacturer, and always into his hands, so as to be swept out easily.
الصفحة 72 - Caetelnuovo, much land has been brought into cultivation by new directions given to the streams of smaller rivers. Before the boracic lakes were turned to profitable account, their fetid smell — their frightful appearance, agitating the earth around them by the ceaseless explosions of boiling water, and not less the terrors with which superstition invested them,* made the lagoons themselves to be regarded as public nuisances, and gave to the surrounding country a character which alienated all attempts...
