In my experience it has rarely happened that a novitiate has felt any inconvenience on his first entrance into the bath. The practised bather is never disturbed from the beginning to the end of the process. But the beginner may, after the first quarter of an hour, or when the perspiration is coming forth in abundance, feel a little oppression, sometimes a little faintness, and sometimes a little increased action of the heart. WHENEVER THIS IS THE CASE HE SHOULD STEP OUT OF THE CALIDARIUM; if there be a Tepidarium he will go into it, if not, he may step into the Frigidarium. The uneasy feeling soon passes away, and then he should return to the Calidarium. He may do this as often as he likes, and with the most perfect safety; and _with this hint_ it will be his own fault if he suffer any inconvenience whatever. The remedy is not so simple when, as sometimes happens, the fount of perspiration is as yet unopened, when the bather has never perspired, or to a very imperfect and trifling extent. Here, of course, the relief which is afforded to the system by perspiration is absent, and the bather may be seriously incommoded. He must not persist; force is antagonistic to the animal economy; he must succumb, and essay to bring about perspiration by the steady use of the vapour bath,--by such a bath, in fact, as the middle room of the Turkish bath. I know many persons who have never perspired, to whom the luxury of the bath is consequently lost. I know others who cannot perspire in dry air, but can do so in vapour. How frequently we are brought to reflect on the wisdom of the Turks, who have added so much vapour to their bath since they received it as an inheritance from the Romans. How long shall I continue in the bath, says Amicus?--As long, my friend, as may be agreeable to yourself. You do not ask me how long you shall eat, nor how long you should sit at table. The instinct that tells you to place your knife and fork across your plate, must also direct you in finishing your bath. Something will depend, it is true, on the temperature, and the rapidity of the process of perspiration. If the temperature have been very agreeable, and perspiration slow, continuous, and efficient, you may pass the best part of an hour in the Calidarium. If it have been too hot, and the process untimely hurried, you must bring your enjoyment more speedily to an end.
