_First._--It is manifestly true that the most of diseases, (the exceptions are comparatively few), can be cured by the use of medicines. It is also true that these can generally be administered with more convenience and less expenditure of time to the practitioner than electricity; and this is a great advantage. The author is often asked if he thinks his electric system will ever supersede the use of medicines. His answer is uniformly, "No." It takes too much time for that. Where the population is crowded, as in cities and large towns, it is often the case, especially in times of prevailing epidemic, that a physician can prescribe medicine for half a dozen or more patients in the time required to treat one electrically. To reject medicines and rely alone on electricity would, in periods and places of prevailing sickness, leave many sufferers without professional service, or would require that the proportion of doctors to the whole population should be largely increased--a thing certainly not often to be desired. So much, candor must concede. _Second._--It is not quite true that medicines are usually less annoying to the patient than electricity as _we_ use it. As administered by others, it is often nearly intolerable. In our hands, on the contrary, it seldom inflicts any pain or distress, and almost invariably becomes agreeable to the patient after a very few applications. We have no occasion to torture our patients in order to cure them. But the cases are comparatively rare where medicines are not offensive; commonly they are excessively so. _Third._--In not a few diseases, and these among the most dangerous or distressful, the electric current, employed according to the system here taught, is able to reach, control and cure, with facility, where medicines are but slowly, and in most instances imperfectly successful, or fail altogether. This is said, or meant to be said, not invidiously nor boastingly, but in the candid utterance of a great and practically demonstrated truth. It is, perhaps, most _often_ exemplified in neuralgic, rheumatic and paralytic affections. The author is happy to acknowledge that these diseases are frequently mitigated, and occasionally cured, by means of electrical treatment administered by those who know nothing of the system here taught. But the important fact is, in _their_ hands there is _no certainty_ as to the effect before trial. Under _this_ system, the kind of effect is as certainly known before as after the trial, since it can be made one thing or another _at will_.
