The _Climate_ of the Eighteen Provinces has been represented in meteorological tables sufficiently well to ascertain its general salubrity. Pestilences do not frequently visit the land, nor, as in Southern India, is it deluged with rain during one monsoon, and parched with drought during the other. The average temperature of the whole empire is lower than that of any other country on the same latitude, and the coast is subject to the same extremes as that of the Atlantic States in America. The isothermal line of 70° F. as the average for the year, which passes south of Canton, runs by Cairo and New Orleans, eight degrees north of it; the line of 60° F. average passes from Shanghai to Marseilles, Raleigh, St. Louis, and north of San Francisco; and the line of 50° F. average goes near Peking, thence on to Vienna, Dublin, Philadelphia, and Puget’s Sound, in lat. 52°. These various lines show that while Shanghai and Peking have temperatures similar to Raleigh and Philadelphia, nearly on their own parallels, Canton is the coldest place on the globe in its latitude, and the only place within the tropics where snow falls near the sea-shore. One result of this projection of the temperate zone into the tropical is seen in the greater vigor and size of the people of the three southern provinces over any races on the same parallel elsewhere; and the productions are not so strictly tropical. The isothermal lines for the year, as given above, are not so irregular as those for winter. The line of 60° F. runs by the south of Formosa and Hongkong, to Cairo and St. Augustine, a range of nine degrees; but the winter line of 40° F. passes from Shanghai to Constantinople, Milan, Dublin, and Raleigh, ending at Puget’s Sound, a range of twenty degrees. A third line of 32° for winter passes through Shantung to N. Tibet and the Black Sea, Norway, New York, and Sitka--a range of twenty-five degrees.
