“In many of those obscure affections called nervous, unconnected with inflammation, exercise and traveling in this climate, are frequently powerful and efficient remedies. “_Chronic rheumatism_, though apparently much less under the influence of meteorological causes than pulmonic affections, will be often benefited by a winter residence in Florida. As these cases often resist the best directed efforts of medicines, it is the only remedy which the northern physician can recommend with a reasonable prospect of success. “When there exists a general delicacy of the constitution in _childhood_, often the rubeola, or scarlatina manifesting itself by symptoms indicative of a scrofulous disposition, a winter residence in a warm climate frequently produces the most salutary effects. “Another form of disease remains to be alluded to, in which change of climate promises healing power, viz.: _premature decay_ of the _constitution_, characterized by general evidence of deteriorated health, whilst some tissue or organ important to life commonly manifests symptoms of abnormal action. This remarkable change occurs without any obvious cause, and is not unappropriately termed in common parlance, ‘a breaking up of the constitution.’ In treating of the climate of Florida, the primary object held in view, is to direct attention to its fitness as a winter residence for northern invalids. “A comparison with the most favored situation on the continent of Europe and the islands held in the highest estimation for mildness and equability of climate, affords results in no way disparaging. A comparison of the mean temperature of winter and summer, that of the coldest and warmest months and seasons, furnishes results generally in favor of the Peninsula of Florida. “On the coast of Florida, the average number of fair days, is about 250; while in the Northern States, the average number of fair days per annum, is about 120. Though climate is one of the most powerful remedial agents, and one, too, which in many cases will admit no substitute, yet much permanent advantage will not result, either from traveling or change of climate, unless the invalid adheres strictly to such regimen as his case may require.
