cannot be overrated. I deem it superior in this respect to any other known agent. This effect manifests itself _immediately_ by a feeling of exhilaration and unwonted vigor, _remotely_ by an improvement—where there is a margin for such—in the performance of some or all of the physiological functions, as well as by a gradual but nevertheless marked _increase in weight_. Most striking among the tonic influences of the baths, are those that occur within the sphere of the digestive and sexual apparatuses. I will first consider the effects on THE DIGESTIVE APPARATUS, which may be subdivided into those on _a_) the appetite, _b_) digestion, absorption and assimilation, and _c_) alvine excretion. The improvement of the appetite under electro-balneological treatment is one of the most constant effects of this. While a series of baths will produce permanent results in this respect, an increase of the appetite, in some instances amounting to positive hunger, is a tolerably uniform and more or less immediate result of each separate bath. The permanent improvement of the appetite is relative. Not very appreciable where this is normal, it becomes most marked where the appetite has from some cause been impaired. The effect on the appetite is _definite_. The effects on absorption and assimilation are _presumptive_; but when we couple the absence of any corresponding difficulty in digesting the increased supply of food, with the increase before alluded to in the weight of the body, their assumption becomes fully justifiable. It is these combined influences that make the electric bath so valuable a remedy in almost all forms of dyspepsia. The influence on the alvine process is if anything even more marked than that on the assimilative process. Where the action of the bowels is normal, it is not modified permanently by the electric bath, although we often have, as an immediate consequence, a cathartic effect that manifests itself as a more or less watery evacuation, either a few hours after the bath or on the succeeding day. Where the fecal process however is sluggish, the improvement resulting from the baths is very striking. I shall recur more fully to this subject under the head of constipation.
