Did, then, the principle evolved accord with the pathology and phenomena of disease? And did it fulfill the indications required? If not, we ask by what means was the disease arrested, and all the urgent symptoms mitigated and relieved, or by what were the good effects produced, and the normal action for a time restored? Can the result be reasonably accounted for on any other principle than the one assigned--the stimulating power of the free caloric? We think not; for it accords most perfectly with the pathology and the peculiar phenomena of the disease. It assuaged the more urgent symptoms, answered the imperious demand of the waning powers, revivified and reinvigorated the vital energies, and restored for the time the normal tone of the system. What more could be desired in any single agent than the result here obtained? That it accomplished all this, there can be no question, according to the statement of the learned professors who have repeatedly witnessed and described the results. The question, however, will arise, Can this principle be rendered available? Most certainly it can; and though it may not be convenient to introduce free caloric into the stomach, we can, by combination, introduce a stimulant of equal potency which shall be equally as prompt, effective and diffusive in its action, similar in its influence, and similar in its results. It is the principle--not the precise element for which we contend. It is universally admitted that in many instances we may learn much from observing the manner of death which, in a majority of these cases of cholera, may be described by the term asthenia--a death similar to that which occurs in congestive fevers, and in some cases of accidental poisoning. Perhaps the most striking fact observed in these cases is the perfect exhaustion attending the last moments of existence, and the quiet, undisturbed manner in which life terminates. This very clearly shows the exhausting nature and congestive character of the disease, and gives us an idea of the course of treatment necessary to be pursued. If, then, there is anything to be learned from this source relative to its treatment, it does most certainly corroborate and strengthen the position we have here taken.
