fever, and increased progressively in violence, carrying off numbers of the inhabitants. A.D. 1798. The preceding winter was severe and long. The summer, this year, was remarkably dry and sultry; the rivers afterwards inundated the adjoining country, heavy rains falling at the same time. Catarrhs, pleurisies, and sore throats prevailed, with bilious fevers. In the autumn, grasshoppers infested the country round about Pennsylvania and New England, and a pestilential fever commenced and spread dismay among the inhabitants: many were carried off by it. The citizens of New York, Philadelphia, Wilmington, Newport, Albany, Boston, Portsmouth, and New London, suffered greatly from this disease, which exhibited both bubo and carbuncle, with many other symptoms of the true plague. A peculiar fog or vapour was observed in New York during the most fatal period of this pestilence, especially in the month of September. Lake and marsh fevers prevailed also about this period in the low and swampy districts, such as Milford, &c. This yellow pestilence was less generally characterized by inflammatory action, and venesection was attended with less salutary effects than on former occasions. A.D. 1799. In Barbary, 3000 died daily from severe pestilence: at Fez alone, 247,000 persons are said to have perished in consequence. In Morocco, pestilence was preceded by famine, induced by extreme elemental disturbance. At Mogador it broke out, in April, in the form of virulent small-pox; by July it had assumed the type of the most deadly species of plague: this fatal disease ceased in October, after carrying off numbers. At a small village called Diabet, situated about two miles south-east of Mogador, it raged with great violence for twenty-one days, carrying off during that period one hundred persons out of one hundred and thirty. Many populous villages, in the extensive Shellah province of Haha, suffered in a similar manner. The birds deserted their former abodes during the prevalence of this pestilence. The Emperor, it is reported, had the plague twice during the time. The summer in the United States of America, this year, 1799, was sultry and dry, with much thunder and lightning, succeeded by deluging rains; the autumn was variable, and the winter severe; the following spring was cold and late, and yellow fever showed itself to a certain extent in many of the States.
