Excerpt from Memorial to Congress on the Cultivation of the Cinchona Tree in the United States There is no substitute for these. They are universally relied on for this purpose. In all countries, and at all periods, since the discovery of the properties of this invaluable and incomparable substance, amidst all the conflicting dogmas of different medical doctrines, Peruvian bark has never failed to sustain its reputation, and to answer the expectations that have rested upon it. Amidst the manifold uncertainties of medical science, and the perpetual contingencies of medical art; amidst the disheartening scientific infidelity which has lately been taking possession of the medical mind, shaking to its deepest foundations the firm old faith in the potency of drugs, and threatening to overturn and demolish it altogether, it is gratifying and consolatory to feel that here, at least, we stand upon solid ground; that here we may hold that there is one great and important therapeutical relationship definitely and positively ascertained and established, defying alike the open assaults of quackery from without, and the treacherous machina tions of indolent skepticism from within. - (bartlett on Fevers.)
