That the air is much more humid than in our more northern regions is sufficiently cognizable to the senses. ‘The dews, even in the winter, are generally very heavy. ‘To guard against the oxidation of metals, as for example surgical instruments, isa matter of extreme difficulty. During the summer, books become covered with mould, and keys rust in one’s pocket. Fungi flourish luxuriantly. The author has known a substance of this kind spring up in one night, and so incor- porate itself with the tissue of a woollen garment, as to render separ- ation impracticable. As the rains, however, generally fall at a parti- cular season, the atmosphere in winter is comparatively dry and serene. The following abstract of the monthly fall of rain at Key West, is the mean result of five years’ observations :— Jan. Feb. Mar. April May June July Aug. Sept. Oct. Nov. Dec. An. Average 1,82 1.34 1.98 1.09 6.34 2.39 2.84 3,30 435 3.33 1.49 41.13 31.40 It will be observed that during six months, from November to May, the proportion of rain is but 8.84 inches. It has been already remarked that in tropical climates a portion of the year is known as the rainy season, and that the same quantity descends in a much shorter space of time than in the temperate zone ; and that, conse- quently, the proportion of fair days and clear skies is infinitely in favor of the former., In the two tables just given, in which the ratios are monthly averages, these results are strikingly evidenced. At Fort King, the annual number of fair days is 809, whilst on the northern $](https://iiif.wellcomecollection.org/image/b33288379_0070.jp2/full/800%2C/0/default.jpg)
