A.D. 1794, an awful earthquake was felt at Naples, and Vesuvius, pouring forth its flames, overwhelmed the city of Torre del Greco. The following year, the weather was uncommonly bad, the spring cold and late, the summer suffocatingly hot, damp, and rainy, whilst south winds were prevalent,--the fruits perished from mould. There was a disease among vegetables, especially the potatoes and cabbages. A dense moisture penetrated into the inmost recesses of the houses, even into desks, bureaux, &c., and the walls appeared covered with a damp white mould, which destroyed the paper-hangings. Millions of mosquitoes and other insects were generated; in fact, a pestilential constitution of the air, answering to the description given by Hippocrates and other writers, was evidenced by these signs. Yellow fever raged with great violence in many parts of the United States of America, viz. in Philadelphia, New York, Charleston, &c., and continued until 1800. “In the whole course of my life,” says Professor Kemp, writing to Dr. Baily on yellow fever, “I never experienced a state of air so distressingly debilitating, and unfriendly to my spirits.” On the 6th of February, this year, a severe shock of an earthquake was felt at Vienna. At this period 10,000 persons lost their lives in three towns of Turkey by a similar catastrophe. CHAPTER VIII. FROM A.D. 1795 TO 1848. A.D. 1795, a severe earthquake was felt on the 17th of July at Manchester and in its neighbourhood: there was a second shock afterwards on the 18th of October. On the 6th of November, in the same year, a violent storm destroyed many lives and much property in England. On the 24th of the following month, December, a severe frost set in, and continued until the 23rd of January. Murrain committed great ravages in Lombardy amongst horned cattle. Professor Count Moscati and Drs. Deho, Bonvicini, and Gherardini published a description of its symptoms, amongst which were observable great rigidity and tension in the necks of animals, and also great sensibility along the spinal column, towards the termination of the malady. Two years after, 1797, a similar epidemic prevailed in the Venetian States, especially in Friuli: horses, sheep, and poultry suffered from this malady, as well as horned cattle. A severe earthquake, this year, 1796, destroyed the whole country between Santa Fé and Panama, including the cities of Cusco and Quito; 40,000 of the inhabitants were in one second hurled into eternity. The seasons were intemperate in the United States. Bilious remittent or yellow fever prevailed at New York, Charleston, Boston, Newburyport, Philadelphia, and in various others of the States. The year following, 1797, the epidemic continued to cause great mortality in the States, especially in Norfolk, Providence, Portland, and Savannah, and it extended thence to New Orleans: it commenced with the symptoms of common remittent
