This periodical contained also notable articles on quina. These appeared in the eighth and twelfth volumes. Juan López Canizares is said to have been the first European to acquire knowledge of the medicinal properties of this plant, communicated to him by an Indian. In 1630, knowing that the wife of the viceroy, the Condesa de Chinchón, was ill with an exhausting intermittent fever, López sent a quantity of quina to the viceroy, and this was administered to the countess by Dr. Juan de Vega, with eminently satisfactory results. This incident induced Linnæus to give the plant the name of Chinchona. Some of the bark in the form of a powder was taken to Madrid, where it was examined by physicians and rejected as a medicine. It was nevertheless used, and noteworthy cures were effected. Here it was known as “pulvos de la condesa.” It was later taken to Rome by Jesuits, and became known in Italy, France, and Germany as Jesuits’ powder. [Sidenote: Opposition to use of quina] Some light is thrown on the spirit of the seventeenth century by its reception generally in Europe. Persons who observed its effects could not deny its efficacy, but they attributed these effects to a pact which the Peruvians had made with the devil. It was discredited in France and Germany; the English prohibited its use; and the learned men of Salamanca maintained that it was an unpardonable sin for a physician to prescribe it. Late in the eighteenth century, in spite of the fact that Charles III tried to encourage the extraction of chinchona bark, certain physicians in Spain continued to speak of it as a remedy that was worse than the disease; but its properties had already attracted the attention, and called forth the commendation of Dr. José Celestino Mutis, the distinguished botanist of New Granada.[224] [Sidenote: Gabriel Moreno] Dr. Gabriel Moreno, a distinguished physician, who was born in Peru in 1735, occupied a prominent place among the scientific men of South America during the last half of the eighteenth century. His special field of research was Botany. The _Mercurio peruano_ contains an article on coca by him. He published other papers and a series of biographies of distinguished Peruvians: Francisco Ruiz Lozano, professor of mathematics; Dr. Juan Ramón Koenig, the first cosmographer of Peru; and Dr. Cosme Bueno, a physician of note in Lima. Dombey, who went to Peru with the botanical expedition of 1778, dedicated a plant, which he discovered to Dr. Moreno, calling it _Morena peruana_.
