Warm Springs, resort, Meriwether co., W Ga. The salutary properties of the water springing from Pine Mt. were known to Native Americans, and white settlers learned of them in the late 18th cent. By the 1830s a resort was established. Destroyed by fire in 1865, it was soon rebuilt and became fashionable by the end of the 19th cent. Franklin D. Roosevelt, who found the water beneficial after his attack of poliomyelitis, established (1927) the Georgia Warm Springs Foundation (now the Roosevelt Warm Springs Institute for Rehabilitation) to help other victims of the disease, and he gave the foundation his 2,600-acre (1,052-hectare) farm there. He retained the cottage known as the Little White House (now a Georgia State Historic Site), in which he died in 1945. Nearby is the twon, incorporated in 1924 as Warm Springs (1990 pop. 407), formerly named Bullochville. Callaway Gardens (14,000 acres/ 5,660 hectares) is to the west.

So-called warm-blooded animals; that is, those that maintain a constant body temperature independent of the environment. The endotherms include the birds and mammals. If heat loss exceeds heat generation, metabolism increases to make up the loss or the animal shivers to raise its body temperature. If heat generation exceeds the heat loss, mechanisms such as panting or perspiring increase heat loss. Unlike ectotherms, endotherms can be active and survive at quite low external temperatures, but because they must produce heat continuously, they require high quantities of “fuel” (i.e., food).
