Conservatism is fast dying out, hidden and smothered by the ever-flowing tidal-waves of progression. Radicalism ceases to become radical, by the daily and hourly recurrence of startling discoveries, and new, unheard-of, and unexpected adaptations of old laws. The mistakes of to-day will be found to be mistakes, and will be rectified. Whenever and wherever freedom holds her sway, evil must work out its own destruction, and good enthrone itself in the hearts of those benefitted by its benign influence. In this spirit, and with such views, let us look at the progress of Medical Science that we may learn from the experience of the past to correctly estimate the developments of the present and aid wisely in the working for a more glorious future.

Medicine has been—not inaptly styled—"The daughter of dreams." From the time of Hippocrates until now, the great body of the profession has been swayed by conflicting theories, founded upon either the wholly unsupported fancies and conjectures of their authors, or unwarrantably built upon isolated facts, often accidental in their occurence, partial in their observation, and improperly understood in their inherent nature and theoretical significance, pointing to a law of action widely different from the one in support of which they had been adduced. All branches of medicine have been involved in these crude absurdities; nor has the nomenclature of any department of science, even in our day, been entirely purged from the errors and misleadings with which the past so fruitfully abounds.

To mark the improvement and advancement in the various branches of medical science; to compare the present with the past; to observe the unfolding growth, maturity, and decay of medical creeds; to discern the power of those master-minds, that, far beyond the ages in which they lived fore-shadowed the forth-coming discoveries that were to make other men immortal; to sigh over the incredulity of whole races, whose blind and dogmatical adherence to the theories of some prominent physiologist or anatomist—was at once silenced by the light of a new truth, suddenly and clearly promulgated by a single mind. To do all these things, was the labor of a whole life; volumes could be written in such investigation, and still thousands of facts be left untouched and forgotten, forever buried in the chaos of medical creeds, medical truths and medical fictions.

Old Physic has for several centuries past drifted in the wrong direction, striking occasionally upon a rock, but finds itself to day further off from shore than ever before.

Medicine, the oldest and most important of all branches of science, has not kept up with developments in other departments, but the rays of light have already deeply penetrated into the darkness of the past, fast undermining the building of the so-called "Rational Medicine" with all its hypothesis and traditions.

It was near the end of the last century, that the idea occurred to a single man, that the reason he had failed in practice must be that the medical profession was entirely on the wrong path. He made the effort to cure diseases on the principle directly opposite to those on which he had been educated to act, and he was successful. He thought a reformation of medicine needful and desirable, and proper to be attempted. He set about it, hoping, if he should succeed in pointing out a more safe, certain and pleasant road to the life-giving and life-renewing fountain of health, that it would be a blessing to suffering humanity. That man was
