![range. There was also much fever in Western Europe these two years. In 1828, febrile disease was par- ticularly severe throughout the Me- diterranean, and plague raged in Egypt, Syria, Greece, Constantiaople, and in tiie Danubian Provinces, and continued to affect these countries, and embraced Odessa the following year. In 1830, plague prevailed from Bassorah to Aleppo along the Eu- phrates, also in Egypt and Syria. The mortalitj' among the troops in the Ionian Islands was as high as the pre- vious year, and petechial typhus raged in the kingdom of Naples. There being no notices of the prevalence of fever over the western coasts of the Black Sea this year, it most probably had diminished considerably, coinci- dent with the advance of cholera west- ward. I have no information as to the prevalence of fever through Eu- rope in 1831, but, according to Muchison, typhus was prevalent in London that year, as also in Scot- land, and the mortality among the Dragoons and Infantry of the Line, from fever, was much higher than usual. In ] 830, as mentioned above, plague prevailed in Egypt and Syria, and, consequently, though these countries are in the same zone as Northern India, cholera did not appear in them in 1830, the first year of this wave in the zone, but was delayed until 1831, the second year, when the plague had greatly diminished. The mor- tality from fever was considerably higher among the troops at Malta and Gibraltar in 1831 than the pre- ceding or following years, Ihough, in the Ionian Islands, it was little more than half what it was in 1830. The deaths from fever among the troopi on the home station were all much reduced in 1832; this disease was less prevalent among the popula- tion in London this year, too, though it was still active in Ireland and Scot- land, and also among the troops in Canada. In 1832, plague was prevalent at Bassora, Bagdad, Mecca, and other places in the Arabian Gulph. I have no information as to whether it was in Egypt. In 1833, there was a large increase of mortality, from fever, among the troops in the Ionian Islands, and a considerable rise at Malta, and in 1834, the ratio in the into Europe, though the cholerific in- fluence was still marked among the troops in the Mediterranean. In 1828, the succeeding cholerific wave passed the isoclinal 30° N., and cholera was very severe in Northern India. In 1829 this wave passed into the zone beyond the isoclinal 53° N., and in August the epidemic broke out in great force at Orenburg, and about the same time, at Tabriz, Tiflis, and in the northern parts of Persia, and it prevailed among the Tartar tribes to the north of the Persian frontier. In 1830, the second year of the wave in this zone, the epidemic extended westward of the Caspian and Volga, and embraced Russia as far as Moscow and Kazan, and in 1831, Poland, south shore of the Baltic, Hamburg, North of England, and even Iceland. In 1830, when another cholerific wave passed into the zone between the isoclinals 30° and 63° N., there was no great activity of the disease in Northern India. In 1831, when the wave passed the isoclinal 63° N., cholera became epidemic in Egypt, and also appeared at Smyrna, Con- stantinople, and in Hungary. The following year, when the wave had entered the zone to the north of the isoclinal 70° N., the epidemic em- braced England, Scotland, Ireland, and North of France, in Europe ; and America, from the Gulf of Mexico to Canada. In 1832, the following cholerific wave passed into the zone beyond the isoclinal 30° N. There was an in- crease of cholera in Northern India, which became still more frequent the following year. This wave passed into the zone beyond the isoclinal 63° in 1833, in which year Lisbon became affected, and Ilavanna, and B 2](https://iiif.wellcomecollection.org/image/b22298198_0007.jp2/full/800%2C/0/default.jpg)
