The sulphuretted hydrogen gas, and the carbonic acid disengaged, could not be ascertained, for want of proper apparatus.
The water of the four baths fitted up for the sick is of the same quality with the one here analyzed; with the difference that in the three last its temperature is less, and that it does not disengage in such quantity the sulphuretted hydrogen nor the carbonic acid.
The new water of Haenk, and that from another jet or source which has been more recently discovered, possess the same qualities with those of the baths; differing, however, in this respect, that they do not disengage sulphuretted hydrogen gas. The water recently discovered, of which the temperature is 91°, contains more iron, but not in such quantity as the waters of the ferruginous bath. It is of a somewhat sweetish acidulated taste, and it leaves a certain asperity on the palate. Reagents act upon these in the same way as they do on the sulphurous water.
PECULIARITIES OBSERVABLE IN THE SULPHUROUS WATER BATHS.
Shortly after having entered the bath, the whole body becomes covered with numberless air-globules of a pearly appearance. Some degree of heat and pungency is felt all over the skin; and, soon after immersion in the water, the smell from it ceases to be perceived. It occasions a slight degree of uneasiness in respiration, arising from the large quantity of carbonic acid and sulphuretted hydrogen which arises from its surface.
MEDICINAL EFFECTS OF THE SULPHUROUS WATER.
According to Dr. Don Jose Maria Adriasola y Arve of Arequipa, it has been found by experience, that, since times of remote antiquity, the baths of the sulphurous waters of Yura have produced the most salutary and specific effects in a great variety of cutaneous diseases. In various instances of chronic disorder of the bowels, and dysentery attended with intestinal ulceration and wasting of the general system, or what has been improperly termed intestinal consumption, Dr. Vargas found that these waters restored the healthy action of the digestive organs, kept up a proper cuticular discharge, and radically cured such apparently hopeless cases.
