I cannot but think that one of the chief obstacles to the progress of the bath in this country, is that little or nothing has been written or said about its proper design, construction, and working, and that no full inquiry has been made into the best possible method of supplying heat to the bathers. As a consequence, we have had, and still have, placed before the public, and meeting with undeserved success, "Turkish baths" which are such only in name--unhealthy, ill-ventilated cellars, where the air, deteriorated at the outset by the heating apparatus, stagnates in the sudatory chambers, and becomes loaded with the exhalations and emanations of the bathers, and not unfrequently charged with a nauseating and disgusting odour. What wonder that we so often hear persons remark that they have tried the bath, but neither enjoyed it nor did it agree with them! The damaging effect of "baths" of this type on the prospects of the true bath is incalculable. In the absence of enlightenment, however, thousands, convinced of the value and benefit of the bathing, periodically attend these miserable substitutes for properly-planned, hygienically-heated, and effectively-ventilated Turkish baths. Viewing any self-evident shortcomings as irremediable evils, ignorant of the true principles of bath construction, and knowing little or nothing of the physiological action of the bath, they have neither the means of ascertaining, nor the power to detect, the genuine article from the harmful substitute. With the public the best bath will be the most elaborate and most flashily decorated, and the moth-and-candle principle comes into play with striking semblance to the original type.
