Per`spi*ra"tion, n. Etym: [Cf. F. perspiration.]
1. The act or process of perspiring.
2. That which is excreted through the skin; sweat.
Note: A man of average weight throws off through the skin during 24
hours about 18 ounces of water, 300 grains of solid matter, and 400
grains of carbonic acid gas. Ordinarily, this constant exhalation is
not apparent, and the excretion is then termed insensible
perspiration.
