On the nineteenth day succeeding that of her landing, my auramentee was detained until a late hour in the evening at his place of business, and was hastening to pay a short visit to his _protégés_, when he was intercepted by a messenger from a friend who had been suddenly prostrated with an attack of the coast fever, who urged him to make haste as the symptoms threatened a fatal issue. We found the doctor in attendance on our arrival, who accepted a thought suggestion, and on the supposition that it was his own, adopted the recommendation, which served to relieve his patient from the fatal tendency, thereby relieving my auramentee from his apprehensions, in time to fulfill his first intentions. This fever scourge of Brazil differs from the yellow type of northern latitudes; as in Rio, during the first stages of accession, it is exceedingly erratic; suddenly appearing in one department to rage with deadly vigor for a few days, and then in apparent transfer, subsiding, to reënact in a remote district its fatal ravages. At a later period of its sway, when the partially exhausted venom has become more generally dispersed, it flits hither and thither with demon activity, fastening upon its prey without premonitory symptoms, perceptible to curative observation, devoted to empirical treatment, although distinctly visible in inceptive cause to our censors. Even with coincident cause and effect clearly exposed for detection in current transfer, the Giga physicians utterly ignore ante-investigation, for prevising the means of prevention. This observance of limits, overleaping adjoining, to locate itself in remote districts, gives plain indication of local infecting agency, and we discover that the fermentable cause was overlooked, and allowed to exhaust itself in putrefactive dissemination. With this hint, in recurring attestation of the fatuous fatalism that will ever attend the curative devisements of humanity, while they neglect the means of prevention, we will resume our demonstration in narrative vindication of the axiom, that remedy is inherent with the cause.
