It has often been stated by close observers of the working of Divine Providence, that "The darkest hour is just before day," and also, that "The Creator ever wisely and well provides agents perfectly adapted to carry out His beneficient designs in the crisis of human affairs." History, both sacred and profane, gives unwavering and very numerous evidences of the justice and verity of these propositions. In matters theological as well as political this is equally the case. When there could scarcely be greater gloom or greater danger, the wise Arbiter of human destinies has educated, nerved, inspired and protected some master-spirit, who has caused light to shine out of darkness, and peace and order to take the place of chaos and destruction. Never were these propositions more fully illustrated than in medical matters towards the close of the past century. All the arts and sciences had received the impetus of new discoveries. The inductive method of investigation had brought out clearly to view first principles, on which it was easy for succeeding generations to build solid, stable and beautiful temples of truth. Astronomy, chemistry, botany and every branch in Natural Philosophy, instead of continuing mere matters of speculative theory, as they were before, became sciences. The sons of Æsculapius alone were enshrouded in an Egyptian darkness, wandering about without guide and compass, rushing wildly to and fro with instruments of deadly power in their hands; whom they wished to heal, they slew; and tortured those whom they fondly hoped might find timely relief from sufferings and woes through their ministrations. The hearts of the benevolent were deeply pained, and the conscientious wavered in their work when they gathered statistics of the results of their labor. A cry ascended heaven-wards from the practitioners of medicine, the longing for better days, seemed seconded by a phalanx of ghostly beings, who had untimely passed away by means of fearful treatment, and by the living miseries of multitudes of shapeless deformed ones, who ever stood unpleasant and incontrovertible witnesses of the cruelties and barbarities of the healing art. With increasing civilization, new and fatal epidemics appeared, reaping a rich harvest for the grim monster--Death--and adding yearly to the per-centage of the ever-increasing bills of mortality. Many an honest practitioner threw away lancet and saddle-bags in despair, while quacks and medical charlatans, profiting by the wranglings of the regulars, and the weariness of the people, drove a reckless but well-paying trade, with nostrums of every character, from the deadliest poison to the simplest house-hold herb. BUT A BRIGTHER DAY WAS ABOUT TO DAWN.
