ity as the sublunary world admits of. and it is the answer to the question how the sea comes to be salt.
It also explains why rain that comes from the south, and the Women Vests & Tank Tops first rains of autumn, are brackish. The south is the warmest of winds and it blows from dry and hot regions. Hence it carries little Vans Sneakers Women moist vapour and that is why it is hot. (It makes no difference even if this is not its true character and it is originally a Unisex cold wind, for it becomes warm on its way by incorporating with itself a great quantity of dry evaporation from the places it passes over.) The north wind, on the other hand, comb ing from moist regions, is full of vapour and therefore cold. It is dry in Women Denim Shorts our part of the world because it drives the clouds away before it, but in the south it is rainy; just as the south is a dry wind in Libya. So the south wind charges the rain that falls with a great quantity of this stuff. Autumn rain is brackish because the heaviest water must fall first; so that that which contains the greatest Dame Adidas Sports Bras quantity of this Women Short Shorts kind of earth descends quickest.
This, too, is why the sea is warm. Everything that has been Barn exposed to fire contains heat potentially, as we see in the case of lye and ashes and the dry and liquid excreta of animals. Indeed those animals which are hottest in the belly have the hottest excreta.
The action of this cause is continually making the sea more salt, but some part of its saltness is always being drawn up with the sweet water. This is less than the sweet water in the same ratio in which the salt and brackish element in rain is less than the sweet, and so the saltness of the sea remains constant on the whole. Salt water when it turns into vapour becomes sweet, and the vapour does not form salt water when it condenses again. This I know by experiment. The same thing is true in every case of the kind: wine and all fluids that evaporate and condense back into a Dame liquid state become water. They all are water modified Męskie Vans Surf by a certain admixture, the nature of which determines their flavour. But this subject must be considered on another more suitable occasion.
For the present let us say Dame this. The sea is there and some of it is continually being drawn up and becoming sweet; this returns from above with the rain. But it is now different from what it was when it was Converse Damskie drawn up, and its weight makes it sink below the sweet water. This process prevents the sea, as it does rivers, from drying up except from local causes (this must happen to sea and rivers alike). On the other hand the parts neither of the earth nor of the sea remain constant but only their whole bulk. For the same thing is true of the earth as of the sea: some of it is carried up and some comes down with the rain, and both that which remains on the surface and that which comes down again change their situations.
There is Adidas Klær more evidence to prove that saltness is due to the admixture of some substance, besides that which we have adduced. Make a vessel of wax and put it in the sea, fastening its mouth in such a way as to prevent any water getting in. links:
