Characteristics.-Selenium was discovered in 1818 by Berzelius, and was named by him after the moon (σελήνη) because it is found associated with Tellurium (Tellus, the earth). It is also found associated with Sulphur. All three belong to the same group of elements. "When precipitated it appears as a red powder, which-melts when heated, and on cooling forms a brittle mass, nearly black, but transmitting red light when in thin plates. When heated in air it takes fire, burns with a blue flame, giving a gaseous Oxide of Selenium, which has a most penetrating and characteristic odour of putrid horse-radish. Sel. undergoes a remarkable change in electrical resistance under the action of light: hence the use of Selenium cells" (Cent. Dict.). Sel. was introduced and proved by Hering. A leading feature of it is the weakness it causes, a weakness involving all parts of the body; easy fatigue from any labour, night-watching, mental exertion, and especially from hot weather. The hotter his body the weaker he is: strength rises as the sun sinks. This debility causes sluggishness: wants to sleep from sheer exhaustion, and is < after. Cannot bear any nervous drain, hence < after coitus or seminal emissions. Impotence. Debility after fevers. When the patient begins to walk after typhoid and feels great weakness in the spine and fears paralysis Sel. is indicated. Irritability, headaches, and other troubles following or < by seminal emissions. The headaches are accompanied by profound melancholy, and may be caused by indulgence in alcoholics or in tea, by hot weather, by over-study, and they are < by strong odours, as of musk, roses, &c. The headaches may be periodical, and are frequently located above the left eye. Many chronic liver affections are met with Sel., the guiding symptoms in such cases being: Enlargement of liver with loss of appetite in the morning; sharp stitching pain < on any movement or pressure, sensitiveness of liver; and, especially, "fine rash over liver region." There is constipation from atony, with impacted faeces: and dribbling of semen after stool, and also after micturition. Sufferings after seminal emissions-mental confusion, headache, almost paralytic weakness of spine, involuntary escape of prostatic fluid. I have cured with Sel. many cases of hoarseness, the special indications being-hoarseness of singers, appearing as soon as they begin to sing; or after long use of the voice; with frequent necessity to clear the throat from accumulation of clear, starchy mucus. Scrofulous and incipient tubercular laryngitis have been cured with Sel. The parallelism with Sulph. is seen all through the pathogenesis of Sel., and perhaps more especially in the skin. Sel. causes itching in folds of skin, as between fingers and about joints, especially the ankle-joint. The itching may occur in small spots, and be accompanied by tingling (showing involvement of the nervous system). The scalp is affected with an eczematous eruption which oozes thin fluid after scratching. Hair falls off scalp and all parts of body. I have frequently relieved "psoriasis palmaris" with Sel., which shows that it has a relation to syphilis. Among the Peculiar Symptoms of Sel. are: Very forgetful in business, but during sleep dreams of what he had forgotten. Coryza ending in diarrhoea. Hungry at night; longing for spirituous liquors, an almost irresistible maniacal desire. Sensation as if a biting drop were forcing its way out of the urethra. Irresistible desire to lie down and sleep; strength leaves him suddenly, especially in hot weather. Very great aversion to a draught of air, either warm, cold, or damp. Aversion to salted food. Pulsation in whole body, especially in abdomen after eating [which I have verified]. Great emaciation of face, hands, legs, feet, affected parts, and single parts. Sel. is Suited to blondes and persons of light complexion. The symptoms are < by touch and pressure. < By motion. > By rest. < After sleep. < By mental exertion. < After seminal losses. < From draught of air, even if warm. < In open air. < From tea; sugar; salt; lemonade; wine. < In hot weather. < By sun, and with the sun's increase (< towards noon, > as sun declines). > Taking cold air or cold water into mouth. < Every afternoon (headaches).
