Non-bathers often express an alarm lest the bath may be weakening. But the bath strengthens, it never weakens, except, as in the instances above narrated, it be used improperly. The idea of weakening is suggested by the loss of fluids by perspiration; but this loss is, as I have endeavoured to show, a gain and not a loss. The expulsion of watery fluids from the economy is a natural process, necessary to our very existence, and without it we should die. It would be very unreasonable to regard the watery fluids expelled by the lungs, by the skin, and by other emunctory organs, as a loss of material necessary to the economy, or a loss which could in any way affect the nervous and muscular powers of the individual otherwise than beneficially--unless, indeed, the loss be inordinate and excessive. Is it not one of the conditions of our healthful existence, that we should earn our bread with the sweat of our brow? and, writhe as we may under the verdict, we must do so, or suffer the evil consequences of a breach of Heaven's law. Mr. Urquhart has the following observations on this subject:-- "There is an impression that the bath is weakening. We can test this in three ways; its effects on those debilitated by disease, on those exhausted by fatigue, and on those who are long exposed to it. "1. In affections of the lungs and intermittent fever, the bath is invariably had recourse to against the debilitating nightly perspirations. The temperature is kept low, not to increase the action of the heart or the secretions; this danger avoided, its effect is to subdue, by a healthy perspiration in a waking state, the unhealthy one in sleep. No one ever heard of any injury from the bath. The moment a person is ailing he is hurried off to it. "2. After long and severe fatigue,--that fatigue such as we never know, successive days and nights on horseback--the bath affords the most astonishing relief. Having performed long journeys on horseback, even to the extent of ninety-four hours, without taking rest, I know by experience its effects in the extremest cases.
