Excerpt: ...diminished by the condensation of its aqueous vapour, and the mean value of the atmospherical pressure, is greatest, and consequently the lowest mark in the barometer is "stormy." 33. From the play of the winds one is tempted to believe that their cause must be some more general disturbance than the theory of mere rarefaction can account for; be that, however, as it may, one thing is certain, namely, that some winds must retard, whilst others must accelerate the earth's rotation. We can't get on well against a strong wind with an umbrella, or even without it; no more can a coach or a steamer; and so there can be no doubt that the constant tradewinds, from east to west, in the very teeth of the earth's motion, although really only left behind, or as it were, held out like a flag swiftly carried in a calm, do retard the earth, whilst the hurricanes, &c, do just the contrary, tending to accelerate its motion. Compensation is everywhere required in nature, and the compensating element for the conservation of the earth's rotation, which would otherwise be affected by the great trade-wind currents, is furnished by the various westerly currents, namely, the predominant, equatorial, and consequently westerly current in the temperate zone; the SW. monsoon of the northern, and the NW. monsoon of the southern Indian Ocean, and lastly, the hurricanes. The latter must certainly contribute a prodigious shove to the struggling rotation in question, when we know that they have shattered the strongest buildings to their foundations, raised men and other animals aloft, and flung Impounders out of a battery to a distance of 420 feet. They have reached Newfoundland, over a distance of 3,000 miles, in six days. Thus, despite the destructive...
