DIAGNOSTIC.
In explanation of this, I will state that in a very large number of cases of disease of an obscure nature, and where, to be candid, the electric bath was employed empirically, or, if you please, tentatively, it has served to point out the locus morbi. The number of cases in which I have made this observation, has been sufficiently large to establish beyond a doubt the fact, that as a rule the electric current makes itself more decidedly and often even painfully felt in any part where a morbid condition exists; whether this be of an inflammatory, neuralgic, rheumatic, traumatic, congestive or other nature, the result is the same. It appears to be somewhat analogous to the “tenderness on pressure” that we find present in many of these conditions. In anæsthesiæ even the current makes itself conspicuous by the absence of its normal effects. The value of this will at once be recognized in connection with a method of electric application which at one and the same time acts on every portion of the body. Local electrization is accompanied by like phenomena, when we happen to strike the right spot. The superiority of the bath as a means of diagnosis is found in the circumstance that here we must touch it.
The great importance of this feature of the electric bath will at once be realized by every physician of much experience, for there can be none such who has not frequently met with subacute or chronic conditions the etiology of which was more or less obscure.
One of the most important effects in its therapeutic application of the electric bath, is its superior excellency as an
