It is quite useless to go into minute topographical details. Those who repair to Gastein will not need them—and those who stay at home will not read them. We shall therefore proceed to the properties of the waters themselves. It has been already observed that they are purer than any spring water, and so clear that you can discern particles of gravel at a depth of some feet. They spring from the earth without noise or bubbling. In certain damp states of the atmosphere, and preceding rains, some people have perceived a slight odour of sulphuretted hydrogen gas in these springs; but it is so questionable that they may be used as common beverage. They suffer no change, when exposed to the air, nor deposit any matter. Their temperature has been stated. When polished silver is immersed for four or five hours in these springs it becomes tinged of a brownish yellow colour, not easily effaced. The water leaves incrustations on wood or other articles exposed to its action, which incrustations are soft, astringent, and bitter to the taste. These waters have a remarkably vivifying effect on flowers, fruits, and vegetables exposed to their influence. In a pint of the water there is about 2⅔ grs. of solid matters, chiefly sulphate and muriate of soda, with a minute trace of iron. When brought near the magnetic needle it draws the loadstone sensibly towards it, which quality diminishes as the water cools. It has been ascertained that the Gastein water is composed of three, instead of two atoms of hydrogen to one atom of oxygen.
