According to our author, the symptoms of the plague do not appear till fifteen days after the infection is received; and this is the reason of a law which subjects to a proof of twenty days every person suspected of being diseased. In this plague it was observed that people of the soundest constitutions were the most subject to it, and the least capable of resisting it. On the other hand, it appeared to spare weak and delicate persons, whose cure, in case of an attack, was much less difficult. A greater number of Moors than of any other nation were attacked by it; and when once they were seized, their case was absolutely desperate. Those who had recovered from the disease were less liable to a second attack, but were not absolutely safe. “I have known some (says our author) who have been ill seven times, and have died of it at last.” Dr. McBride informs us that in the plague which raged at Marseilles and the adjacent places in 1720, people on their first seizure seemed as if intoxicated with drink; they lost the power of their limbs entirely, and became so dejected that they gave themselves over to despair from the very first attack. Along with the bilious vomitings and purgings which generally took place on the second day, quantities of small worms like ascarides were thrown off. The more plentiful these evacuations were, the more salutary; for those who vomited and purged but little sunk down, oppressed with the disease, and died before the fourth day, covered with livid blotches and petechiæ; those who had the largest evacuations had also the most plentiful eruptions of buboes and parotid abscesses. When these appeared, the patients rose, walked about, and became remarkably hungry; the heat and thirst subsided, but the face continued pale and languid, the pulse hard and frequent. On the sixth, seventh, or eighth day, if the suppuration stopped, and the humours went back, then came on oppression, difficulty of breathing, furious delirium and convulsions, which ended in death. When carbuncles, or biles, with mortified sloughs, appeared in different parts of the body, either alone or accompanied with the glandular swellings, the patients scarcely ever escaped. In great numbers of people tumours appeared without any previous febrile symptom, and, in a few cases, went off by resolution; in others they continued in a schirrous state; but it was best when the tumours came to suppuration. These are the most remarkable symptoms of this fatal disease, which have been recorded by the physicians of greatest eminence who have written upon the subject. It remains still to give some particular description of the buboes and carbuncles, which are supposed to constitute in a particular manner the characteristic signs of the distemper. Of these the following account, given by Dr. Alexander Russel, seems to be sufficiently clear and explicit.
