The unfortunate result of this trial of the new disorder rivetted many persons in their prejudices against it; and others who had strenuously recommended its adoption began to stagger, and to fear that they had been deceived; however, as none of those who were inoculated had been in danger, the people did not appear to have taken a thorough dislike to it. To me this was a most anxious time; my establishment of slaves and free people consisted of twenty-five persons, of whom scarcely any had had the small-pox. They were too many to inoculate at once, and therefore I cut off all communication with my neighbours. This was done without much difficulty; Manoel was armed, and was ready to prevent any one from approaching the place, and this I could do without injustice, for the path led only to the house. I had several fierce dogs, which were all let loose on this occasion, notice being given to the neighbourhood of such a measure having been adopted. Considerable zeal has been shewn by the supreme government of Brazil in the introduction of the cow-pox into the country. An establishment has been formed at Recife, consisting of a physician and two surgeons for the inoculation, free of expence, of all persons who apply for this purpose. The inoculation is expressly confined to the matter of the cow-pox. The establishment has not however, yet fixed upon any settled plan for having a constant supply of the matter, and therefore the medical men belonging to it are often obliged to remain inactive for several weeks at a time.
