_Illustration._ A few years since, a poor inebriate was carried to a London hospital in a state of intoxication. He lived but a few hours. On examining his brain, nearly half a gill of fluid, strongly impregnated with gin, was found in the cavities of this organ. This was secreted from the vessels of the brain. HYGIENE OF THE SECRETORY ORGANS. 432. _Unless the secretions are regularly maintained, disease will be the ultimate result._ Let the secretions from the skin be suppressed, and fever or some internal inflammation will follow. If the bile is impeded, digestion will be impaired. If any other secretion is suppressed, it will cause a derangement of the various internal organs. _Observation._ Ardent spirits derange the secretions, and change the structure of the brain. This is one reason why inebriates do not generally live to advanced age. 433. _The quantity of blood influences the character of the secretions._ If it is lessened to any great extent, the secretions will be lessened as well as changed in character. _Illustration._ When a person has lost a considerable quantity of blood, there is a sensation of thirst in the fauces, attended with a cold, pale, dry skin. When reaction comes on, the perspiration is cold, attended with nausea, and sometimes vomiting. -=-=-=-=-=-=-=-=-=-=-=-= 431. What becomes of those substances imbibed by the lymphatics that do not give nourishment to the body. 432-437. _Give the hygiene of the secretory organs._ 432. What effect on the system when the secretions are not regularly maintained? 433. Does the quantity of blood influence the secretions? Give an illustration. -=-=-=-=-=-=-=-=-=-=-=-= 434. _The secretory organs require the stimulus of pure blood._ If this fluid is vitiated, the action of the secretory organs will be more or less modified. Either the quantity will be affected or the quality will be altered. _Observation._ The impurity of the blood arising from the inhalation of the vitiated air of sleeping rooms, diminishes and changes the character of the secretions of the mouth and stomach. This accounts for the thirst, coated tongue, and disagreeable taste of the mouth when impure air is breathed during sleep. The disease it induces, is indigestion or dyspepsia. 435. _The amount of action modifies the condition of the secretory organs._ When a secretory organ is excessively stimulated, its vigor and energy are reduced. The subsequent debility may be so great as to suppress or destroy its functional power. _Illustrations._ 1st. In those sections of the country where flax is spun on a "foot-wheel," it is not unfrequent that the spinners moisten the thread with the secretions of the mouth. This seems to operate economically for a time, but debility of the salivary organs soon follows, which incapacitates them from supplying saliva sufficient to moisten the food, producing in a short time disease of the digestive organs.
