The Mississippi is also more likely to afford us a fair test of ordinary...
Página 535 - Now, the perihelion of the orbit is situated nearly at the place of the northern winter solstice ; so that, were it not for the compensation we have just described, the effect would be to exaggerate the difference of summer and winter in the southern hemisphere, and to moderate it in the northern ; thus producing a more violent alternation of climate in the one hemisphere, and an approach to perpetual spring in the other. As it is, however, no such inequality subsists, but an equal and impartial...
