The plague which happened in Egypt so early as the year 1348, when Constantinople was yet subject to the Greek emperor, and Egypt in possession of Mohammedans, may be supposed to have originated in the latter. But not to mention that there were many other places from which it might be brought, this single instance, not given in detail, is insufficient to overthrow the testimony of the modern inhabitants, who with one consent affirm, whether Mohammedans or Christians, that the plague is not endemial in Egypt, but that all the instances of it which they are able to trace are proved to have been derived from abroad. The learned Dr. Mead has brought the plague from Ethiopia, where famine and the small-pox indeed carry off numbers; but where the plague was never known to exist. It is not remembered to have penetrated far into the Upper Egypt, except in some few instances, when it was known to have been carried thither by the boats from Kahira. No more is required to account for its introduction into Egypt at this day, than the admission, that it is never completely extinct at Constantinople, which, it seems, has scarcely been denied. The imagination of one of our poets has drawn the pestilence from the filth of Kahira, and the mud of the Nile. But, not to mention that there is less disposition to fermentation and putrefaction in the atmosphere of Egypt, than in almost any other that I have heard described, Kahira is very far from being impure. No offensive substance remains in the streets twenty-four hours; and even what is left to annoy passengers in London and Paris for months, is there carried away and preserved for burning. The mud of the Nile becomes dry in a very short space of time after the water has left it, except in the canal (Chalige) which is indeed not very odoriferous; but so far from emitting pestilential exhalations, that the Franks who especially dwell close to it, are never infected with the plague, and are in general among the most healthy of the inhabitants of that metropolis. _Small-pox._ The small-pox is a disease much dreaded by the people of Soudân, whether Moors or Negroes, and little less by the Bedouins of Egypt. The Christians of Kahira are many of them in the habit of inoculating. A few of the Mohammedans use the same practice. It is however almost impossible to persuade them to adopt our mode of treatment.
