=Morphinism.=—_Definition._—A chronic intoxication due to the habitual use of opium, or some of its alkaloids, especially morphine. _Pathology._—There are no characteristic tissue changes, other than that due to indigestion and malnutrition. At death the patient is anemic, the skin dry, sallow and inelastic, the heart and blood vessels show the effects of poor nutrition, and the tissues generally present a starved appearance. The blood disintegrates, causing a discoloration of a brownish color, one or two days after death. _Treatment._—Drain blood from these cases using half strength fluid for the first part of the injection. The more blood obtained, the less the danger of discoloration will be. Give the body a thorough cavity injection in addition to the arterial injection. If your treatment does not eliminate the blood as a factor, the discoloration will occur and then it cannot possibly be removed. In this case the use of cosmetics, if in the hands of a patient operator, will overcome the color. =Plumbism.=—_Synonyms._—Lead-poisoning. _Definition._—A chronic intoxication due to absorption of lead. _Pathology._—The muscles are atrophied and pale in color. Arteriosclerosis of the cerebral blood vessels is found. There may be softening of the brain and hemorrhage. _Treatment._—Drain blood from the veins while injecting fluid in the arteries. The fluid should be used half strength for the first bottle of the injection. Massage the face downward to help eliminate any discoloration of blood origin from cerebral hemorrhage. Give the body a thorough injection both as to arteries and cavities. If the face is unduly pale from this treatment, carmine rouge, judiciously applied will lessen the paleness. =Arsenicism.=—_Definition._—A chronic intoxication caused by the continued absorption of arsenic. _Treatment._—Same as for plumbism. =Mercurialism.=—_Definition._—A chronic mercurial poisoning, caused, either by ingestion of the drug, or by inhalation and absorption of the mineral in the industrial pursuits. _Pathology._—There is an acute inflammation of the mouth, stomach, and intestines. The kidneys are inflamed and the liver is degenerated. _Treatment._—Drain blood from a large vein while the injection is going on. The first bottle of fluid for the injection should be half strength. The cavities should be injected, as intense inflammation takes place in the alimentary tract. =Heat-Stroke.=—_Synonyms._—Sunstroke. _Definition._—Heat-stroke is the result of exposure to intense heat, either from the direct rays of the sun, or the radiation of blasts or furnaces, or to an overheated atmosphere.
