I have no doubt but the epidemy which made its appearance at Cadiz, and all along the southern shores of Spain, immediately as the plague was subsiding in West Barbary, was the same disorder with the one above described, suffering, after its passage to a Christian country, some variation, originating from the different modes of living, and other circumstances; for nothing can be more opposite than the food, dress, customs, and manners of Mohammedans and Christians, notwithstanding the approximation of Spain to Marocco. We have been credibly informed, that it was communicated originally to Spain, by two infected persons, who went from Tangier to Estapona, a small village on the opposite shore; who, after eluding the vigilance of the guards, reached Cadiz. We have also been assured that it was communicated by some infected persons who landed in Spain, from a vessel that had loaded produce at L’araiche in West Barbary. Another account was, that a Spanish privateer, which had occasion to land its crew for the purpose of procuring water in some part of West Barbary, caught the infection from communicating with the natives, and afterwards proceeding to Cadiz, spread it in that town and the adjacent country. It should be observed, for the information of those who may be desirous of investigating the nature of this extraordinary distemper, that, from its character and its symptoms, approximating to the peculiar plague, which (according to the before mentioned Arabic record) ravaged and depopulated West Barbary four centuries since, the Arabs and Moors were of opinion it would subside after the first year, and not appear again the next, as the Egyptian plague does; and agreeably to this opinion, it did not re-appear the second year: neither did St. John’s day, or that season, affect its virulence; but about that period there prevails along the coast of West Barbary a trade wind, which beginning to blow in the month of May, continues throughout the months of June, July, and August, with little intermission. It was apprehended that the influence of this trade wind, added to the superstitious opinion of the plague ceasing on St. John’s day, would stop, or at least sensibly diminish the mortality; but no such thing happened, the wind did set in, as it invariably does, about St. John’s day; the disorder, however, encreased at that period, rather than diminished. Some persons were of opinion, that the infection maintained its virulence till the last; that the decrease of mortality did not originate from a decrease of the _miasma_, but from a decrease of population, and a consequent want of subjects to prey upon; and this indeed is a plausible idea; but admitting it to be just, how are we to account for the almost invariable fatality of the disorder, when at its height, and the comparative innocence of it when on the decline? for _then_, the chance to those who had it, was, that they would recover and survive the malady.
