To the same purpose, the Abbe Mariti says, “The plague does not usually reside in Syria, nor is this the place where it usually begins. It receives this fatal present from Egypt, where its usual seat is Alexandria, Cairo or Damietta. The plague of 1760 came at once from Cairo and Alexandria; to the latter of which it had been brought from Constantinople. When it comes from that capital, as well as from the cities of Smyrna and Salonica, it acquires a peculiar malignity; and its activity never expands itself with more fury than in the plains of Egypt, which it overspreads with incredible rapidity. It is observed, that this plague, so destructive to Egypt, seldom attacks Syria; but that the latter has every thing to dread from a plague hatched in the bosom of Egypt.” The testimony of these three authors, who have all been lately on the spot, must certainly have very great weight, especially when corroborated by that of Dr. Russel; for which see Appendix, No. V. But still there is some difficulty. M. Savary informs us, that, _except in cases of great famine_, the disease never breaks out in Cairo; which certainly implies that in cases of famine it does originate in the city itself; and Mariti, by saying that the Syrians have much reason to dread a plague _hatched in the bosom_ of Egypt, undoubtedly intimates that plagues sometimes do originate in Egypt. Smyrna and Salonica likewise seem to come in for their share of the blame; and Dr. McBride, in his Practice of Physic, informs us, that some parts of Turky are visited by the plague once in six or seven years; and M. Savary says, that Egypt is visited with it once in four or five years; but if Egypt never receives it but from Turky, it would seem that the plague could at least be no more frequent than in that country; or, if the fact be otherwise, that the disease must either originate in Egypt itself, or be brought to it from some other country than Turky. Dr. Timone, in the paper already quoted,[26] tells us, that the plague has taken up its residence in Constantinople; but that, though the seeds of the old plague are scarce ever wanting, yet a new infection is likewise imported from time to time. Thus, in attempting to find out the countries where the plague originates, we are led in a circle. Constantinople accuses Egypt, and Egypt recriminates on Constantinople. Ethiopia, the most distant and least known of those countries which in former times had any connexion with the more civilized parts of the world, for a long time bore the blame of all; but the Jesuit missionaries who resided long in Abyssinia (the ancient Ethiopia) do not mention the plague as more common in that country than some others; neither does Mr. Bruce, in the accounts he has published, take notice of any such thing. Ethiopia could not speak for itself, by reason of the ignorance and barbarity of its inhabitants; and Constantinople is now very much in the same predicament. The investigation of this
