106 THE ESSEX NATURALIST. in 1630; that the grateful lady, when she recovered, caused quantities of this valuable bark to be procured on her behalf, and when she returned to Europe in 1639, had the bark dis- tributed to the ague-stricken tenantry on her husband's estates; that the sufferers who benefited by her benevolence termed the remedy the Countess's Powder; and that, under this name, the new drug found its way into European medical practice. The fact that there is no official record of the receipt by Juan de Vega of the Cinchona Bark which cured the Countess of Chincon does not prove the story we were taught to be an early example of the kind of thing we are accustomed to find in our morning journals. But when we remember that the Count and Countess both suffered from malaria, almost from the time of their arrival in Peru, what surprises us is, not that the Corregidor should present them with what had cured him in 1630, but why it took him eight years to think of doing so ! Our suspicion that the story, as we were told it, may be a propagandist combination of two distinct happenings is strengthened by the existence of the very different one that the Cinchona Bark with which Juan de Vega cured the Countess was given him by an Indian maid of high birth, devoted to the Vicereine, who braved the displeasure of her people by revealing a secret remedy they wished to conceal from their Spanish conquerors. In any case we know now that the story, as we have been told it, resembles modern journalism in certain other particulars. It is true that in 1621 the fourth Count of Chincon married the famous Court beauty Ana d'Osorio. But that lady had died before 1628, when the Count married, as his second wife, Francisca Henriquez de Ribera, and was appointed Viceroy of Peru. It was the Countess Francisca who entered Lima in state as his consort in 1629; it was she whom Dr. Juan de Vega cured of malaria by means of Cinchona Bark in 1638. The distribution by her of Cinchona Bark in Europe is a figment of fancy ; the poor lady never returned to Europe: she died and was buried at Carthagena in Colombia in 1641. That her husband may, as a good Viceroy, have taken steps to create a market in Spain for a valuable Peruvian product we can well believe: that he should, as a good husband, have approved the use, by those who prescribed the drug in Europe, of the name of Countess's Powder, we have little reason to doubt, though the historian
