Section 100 Perspiration
Perspiration is the evacuation1 of the juices of the body through the pores of the skin. It has been calculated (S. 4, N. 4) that there are2 above three hundred millions of pores in the glands of the skin which covers the body of a middle-sized man. Through these pores more than one half3 of what we eat and drink passes off4 by5 insensible6 perspiration. If we consume eight pounds of food in7 a day (App. § 9; S. 27, N. 8), five pounds of it (S. 4, N. 5, B) are insensibly discharged8 by perspiration. During9 a night of seven hours’ sleep we perspire about two10 pounds and a half. At an average we may11 estimate the discharge1 by12 sensible and insensible perspiration at13 from half an ounce to14 four ounces per hour. This (Dies) is a most15 wonderful part16 of the animal economy, and17 is absolutely necessary to18 our health, and even to our very existence.—The Rev. Dr. Dick.
