than to suppose a change in the whole world in order to explain these facts. But we have dwelt longer on this point than it deserves,Ralph Lauren Kortärmade skjortor.
To return to the saltness of the sea: those who create the sea once for all,Chaussures New Balance 420, or indeed generate it at all, cannot account for its saltness. It makes no difference whether the sea is the residue of all the moisture that is about the earth and has been drawn up by the sun, or whether all the flavour existing in the whole mass of sweet water is due to the admixture of a certain kind of earth. Since the total volume of the sea is the same once the water that evaporated has returned,Parajumpers Herreklær Jakke Norge Salg, it follows that it must either have been salt at first too, or, if not at first, then not now either. If it was salt from the very beginning, then we want to know why that was so; and why,Moncler Kurtki Mêskie, if salt water was drawn up then,CG Dame Hybridge Lite Jakke Norge Salg, that is not the case now.
Again, if it is maintained that an admixture of earth makes the sea salt (for they say that earth has many flavours and is washed down by the rivers and so makes the sea salt by its admixture), it is strange that rivers should not be salt too. How can the admixture of this earth have such a striking effect in a great quantity of water and not in each river singly? For the sea, differing in nothing from rivers but in being salt, is evidently simply the totality of river water, and the rivers are the vehicle in which that earth is carried to their common destination.
It is equally absurd to suppose that anything has been explained by calling the sea ‘the sweat of the earth’, like Empedicles. Metaphors are poetical and so that expression of his may satisfy the requirements of a poem,Chaussures Air Jordan 5 Retro Homme, but as a scientific theory it is unsatisfactory. Even in the case of the body it is a question how the sweet liquid drunk becomes salt sweat whether it is merely by the departure of some element in it which is sweetest,Nike LeBron 13 Męskie, or by the admixture of something,CG Menn Carson Parka Norge Salg, as when water is strained through ashes. Actually the saltness seems to be due to the same cause as in the case of the residual liquid that gathers in the bladder. That,arctic parka, too, becomes bitter and salt though the liquid we drink and that contained in our food is sweet. If then the bitterness is due in these cases (as with the water strained through lye) to the presence of a certain sort of stuff that is carried along by the urine (as indeed we actually find a salt deposit settling in chamber-pots) and is secreted from the flesh in sweat (as if the departing moisture were washing the stuff out of the body),Män Vests, then no doubt the admixture of something earthy with the water is what makes the sea salt.
Now in the body stuff of this kind,Chaussures Nike Air Max Excellerate Homme, viz. the sediment of food, is due to failure to digest: but how there came to be any such thing in the earth requires explanation. Besides,Ralph Lauren Big Pony Polos, how can the drying and warming of the earth cause the secretion such a great quantity of water; especially as that must be a mere fragment of what is left in the earth? Again, waiving the question of quantity, why does not the earth sweat now when it happens to be in proce
