The lungs throw off poisons--eliminate the volatile substances; but probably their greatest role is that of neutralizing poisons, such as tobacco, volatile drugs, and toxins from fermenting foods. Their action is not experienced unless respiration is normal and a sufficient number of red corpuscles are found in the blood. Breathing may be normal; but in anemia, dysemia, and chlorosis, oxygen starvation is experienced, and certainly there must be a failure to neutralize poisons which depend on a sufficient amount of oxygen.

The skin eliminates volatile substances. An animal varnished, shutting off elimination and radiation, dies in coma. The temperature falls; the urine becomes scanty; albumin and blood show in the urine before death. The same occurs if an extensive burn is suffered, or if the skin is covered by a disease.

To a certain degree the functions of the skin are inhibited by heavy underwear. It is a common thing to have consultants come in the winter wearing two or three heavy undershirts. In spite of this, they invariably complain of feeling chilly. The fact is that they dress so heavily that they suffer more or less as the varnished animal--namely, from suppressed skin function. Such subjects cannot be cured until they are rid of their bad habits--especially that of overdressing. These patients are always surprised to find that they are more comfortable in every way with the thinnest gauze than they were with all the clothing they could pile on themselves. The skin is a protector; when pampered and spoiled, it goes out of business.

Uremia is caused by the kidneys endeavoring to do vicarious work for the liver and skin.

Strong condiments, alcoholics, and toxins generally overwork the kidneys. When these organs are long overstimulated by overwork, they flag; and if they fail to carry off the urine--if they fail to separate the urinary elements from the blood--the excretion will be retained and uremia will be developed.
