Well, now, as to indigestion. As the reader knows, the whole internal surface of the body is lined with a mucous membrane, which is analagous to the skin or external covering, and as the one is so will the other be; mucous indigestion, therefore, it may be clearly perceived is averted by the use of the Bath. But indigestion may proceed from loss of nerve power, or from a badly acting liver or spleen, or from weakness of the heart, etc. And the Bath strengthens and tones the nervous system far more than any tonic we wot of, moreover its constant use makes the work which the liver and spleen have to perform, mere play, so to speak; and if the Bath invigorates muscle--and we know it does--it must act as a roborant or tonic to the heart itself, which is composed for the most part of muscular tissues. Many people produce a species of irritable indigestion, by the use of stimulants, for this the Anglo-Turkish bath is an almost certain cure, as it relieves internal congestions, steadies the nerves and produces refreshing sleep. Many poisons are generated in the system, to which if free vent be not given by means of the pores of a healthily acting skin, mischief is sure sooner or later to arise, such mischief for instance as gout and rheumatism, to which reference has already been made. But the condition of the kidneys is seldom or never studied by anyone and yet if they do not act sufficiently well to expel urea from the blood, a more or less injurious effect is caused upon the brain and nerve centres. This the periodical use of the Anglo-Turkish bath, would tend to remove. We all know the demoralising effect that the first glass of spirits is said to have upon a man inclined to the abuse of intoxicants; it so affects his brain that he no longer knows, or he disregards right form wrong as far as his health is concerned. But a similar demoralisation of brain tissue, may be produced by poisons positively generated in the system; at least this is our opinion. Those, for example, who have been given to alcohol, often keep "steady" as they phrase it for a month or months, then suddenly or gradually, as the case may be, break out again. This is doubtless caused by the play of some accumulated system-propagated poison on the brain and nerves. This poison may be urea, or it may be some acid, it matters not, it is in the blood and it ought to be eliminated and we earnestly advise those, who would be abstainers but who find it difficult to long remain so, to fly at once for relief to the hot-air bath, whenever the "_tempter_," as platform orators call it, seems to urge them to take once more to stimulants.
