It is necessary, for the sake of those to whom the whole subject may be new, to give in the smallest possible compass the substance of the Homeopathic Doctrine. Samuel Hahnemann, its founder, is a German physician, now living in Paris, at the age of eighty-seven years. In 1796 he published the first paper containing his peculiar notions; in 1805 his first work on the subject; in 1810 his somewhat famous "Organon of the Healing Art;" the next year what he called the "Pure Materia Medica;" and in 1828 his last work, the "Treatise on Chronic Diseases." He has therefore been writing at intervals on his favorite subject for nearly half a century.
The second great fact which Hahnemann professes to have established is the efficacy of medicinal substances reduced to a wonderful degree of minuteness or dilution. The following account of his mode of preparing his medicines is from his work on Chronic Diseases, which has not, I believe, yet been translated into English. A grain of the substance, if it is solid, a drop if it is liquid, is to be added to about a third part of one hundred grains of sugar of milk in an unglazed porcelain capsule which has had the polish removed from the lower part of its cavity by rubbing it with wet sand; they are to be mingled for an instant with a bone or horn spatula, and then rubbed together for six minutes; then the mass is to be scraped together from the mortar and pestle, which is to take four minutes; then to be again rubbed for six minutes. Four minutes are then to be devoted to scraping the powder into a heap, and the second third of the hundred grains of sugar of milk to be added. Then they are to be stirred an instant and rubbed six minutes, again to be scraped together four minutes and forcibly rubbed six; once more scraped together for four minutes, when the last third of the hundred grains of sugar of milk is to be added and mingled by stirring with the spatula; six minutes of forcible rubbing, four of scraping together, and six more (positively the last six) of rubbing, finish this part of the process.
