M. Kasloff has been careful to erect his building on the most convenient spot, and where the temperature of the water is most moderate. It is constructed of wood, in the middle of a stream, and is in the proportion of sixteen feet long by eight wide. It is divided into two apartments, each of six or seven feet square, and as many high: the one which is nearest to the side of the spring, and under which the water is consequently warmer, is appropriated for bathing; the other serves for a dressing-room; and for this purpose there are wide benches above the level of the water; in the middle also a certain space is left to wash if we be disposed. There is one circumstance that renders these baths very agreeable, the warmth of the water communicates itself sufficiently to the dressing-room to prevent us from catching cold; and it penetrates the body to such a degree, as to be felt even for the space of an hour or two after we have left the bath. We lodged near these baths in a kind of barns, covered with thatch, and whose timber work consisted of the trunks and branches of trees. We occupied two, which had been built on purpose for us, and in so short a time, that I knew not how to credit the report; but I had soon the conviction of my own eyes. That which was to the south of the stream, having been found too small and too damp, M. Kasloff ordered another of six or eight yards extent, to be built on the opposite side, where the soil was less swampy. It was the business of a day; in the evening it was finished, though an additional staircase had been cut out to form a communication between the barn and the bathing house, whose door was to the north. Our habitations being insupportable during the night, on account of the cold, M. Kasloff resolved to quit them, four days after our arrival. We returned to the village to shelter ourselves with the toyon; but the attraction of the baths led us back every day, oftener twice than once, and we scarcely ever came away without bathing. The various constructions which M. Kasloff ordered for the greater convenience of his establishment, detained us two days longer. Animated by a love of virtue and humanity, he enjoyed the pleasure of having procured these salutary and pleasant baths for his poor Kamtschadales. The uninformed state of their minds, or perhaps their indolence, would, without his succour, have deprived them of this benefit, notwithstanding their extreme confidence in these hot springs for the cure of a variety of diseases[24]. This made M. Kasloff desirous of ascertaining the properties of these waters; we agreed to analyse them, by means of a process which had been given him for this purpose. But before I speak of the result of our experiments, it is necessary to transcribe the process, in order the better to trace the mode we adopted. "Water in general may contain, "1. Fixed air; in that case it has a sharp and sourish taste, like lemonade, without sugar.
