![trasts strongly with the mild and salubrious climate of the mountain regions—results that will be developed more fully in the investiga- tion of endemic influences. It may not be amiss, as illustrative of the comparative tempera- ture of the Atlantic Plain and the adjacent mountain region, to pre- sent here a few thermometrical data, however limited in extent, noted, during the summers of 1839 and 1840 at Flat Rock, Buncombe County, North Carolina. | Places of Observation. | Lat. | Mean Temperature. July. | Aug. | Sept. | Oct. Fort Monroe, Coast of Virginia, | 37°00’ | 80° 70° 72° 64° Flat Rock, Buncombe, N. C., 35° 30’ | 69° } 70° 62° 61° Charleston, South Carolina, 32° 45’ | 81° 81°° | FT eens Flat Rock is about 250 miles from the Atlantic, and is. elevated given is also a mere approximation derived from general knowledge. The observations made at Charleston embrace the same years as those at Flat Rock, but the data at Fort Monroe comprise the years 1828, 29, and 30. It is thus seen that the difference of temperature at Flat Rock and the other two points, taking an average of the latter, is in July 11°, August 10°, September 13°, and October 6°. As regards the monthly range of the thermometer, little difference is presented. 3. Tur Sovtuern Division, which is characterized by. the pre- dominance of high temperature, remains to.be considered. ‘The cli- mate of this region is fully illustrated by the posts contained in Table [IT] p. 55. On approaching the southern coast, climate undergoes a most re- markable modification. ‘The seasons glide imperceptibly into each other, exhibiting no great extremes. ‘This is strikingly illustrated on comparing the difference between the mean temperature of summer and winter at Fort Snelling, Iowa, and at Key West, at the southern point of Florida, the former being 56°.60, and the latter only 11°.34. Compared with the other regions of the United States, the Peninsu- la of Florida has a climate wholly peculiar. ‘The lime, the orange, and the fig, find there a genial temperature ; the course of vegetable is unceasing; culinary vegetables are cultivated, and wild flowers spring up and flourish in the month of January ; and so little is the temperature of the lakes and rivers diminished during the winter months, that one may almost at any time bathe in their waters. The ~ climate is so exceedingly mild and uniform, that besides the vegeta-](https://iiif.wellcomecollection.org/image/b33288379_0064.jp2/full/800%2C/0/default.jpg)
