CLIMATE.
Obviously, the most important of these characteristics is climate. Climatology, from being a mere speculative theory, has arisen to the deserved rank of a science. The influence of the climate of a country on the national character has long been observed and acknowledged. The languid but passionate temperaments of the South are like its volcanoes, now quiet and silent, anon bursting forth with terrible activity, flooding entire cities with molten fire; or, like its skies, now sunny, cloudless, an hour hence convulsed with lightnings and deluging the earth with passionate rain; or like its winds, to-day soft, balmy, with healing on their wings, to-night the wind fiend, the destroying simoom, rushing through the land, withering and scorching every flower and blade of herbage on its way. On the other hand, the calm, phlegmatic temperament of the North accords well with her silent mountains, her serener skies, and her less vehement, but chilling winds. The South, too, is the native home of the most violent acute diseases, such as yellow fever and cholera. But, aside from this general climatic influence, there is the yet more restricted one of locality. It has often been observed that certain classes of diseases are most prevalent in certain localities, the prevalence in every instance being due to peculiarities of climate.
