8Since, therefore, all the large known rivers in the world seem to flow from the north, and towards the land of Africa, because those are in the southern regions under the sun’s course, where there is little moisture, and but few springs and rivers, it follows that those sources which are in the north and north-east, are much better than others, unless they run over a sulphureous, aluminous, or bituminous soil, for their quality is thereby changed, and whether hot or cold, their water is then of bad smell and taste. It is not that water, by its nature, is hot, but when cold, it is heated by running over a hot soil, and issues warm from the earth through the different pores: it does not, however, long remain in that state, but soon becomes cold; whereas, if it were naturally hot, it would not so soon grow cool; for it does not lose its taste, smell, and colour, which, from the purity of its nature, remain unchanged and discoloured.
