TINCTURE OF OPIUM, OR LAUDANUM:--"Laudanum, or the tincture of opium, is a mixture of gum opium with alcohol and water, the solution consisting of equal parts of alcohol and water. Each ounce contains 5-1/2 grains of powdered gum opium and half an ounce of alcohol, and is equal in alcoholic strength to one ounce of strong whisky. The ordinary medical dose is from 12 to 15 minims, or from 25 to 30 drops. It is much used as a domestic remedy for pain from any cause, such as ear or toothache, indigestion, insomnia, summer complaints with children or adults, and is often used in poultices over painful sores or swellings. It is also used in many medicines for throat and lung troubles, in nearly all medicines for painful chronic diseases, and in many of the well advertised spring tonics, as well as in nearly all the compounds that are offered for sale for blood troubles, or as alteratives. The opium in laudanum acts the same as morphine, or any other of the thirty preparations of opium, officially recognized by the medical profession. PAREGORIC:--"Paregoric of standard grade is half alcohol, which is as strong of alcohol as high proof whisky. It contains a little opium, some benzoic acid, oil of anise, and camphor. The dose is from 15 to 60 drops. COCAINE:--"Cocaine is an alkaloid of coca leaves, and is used in medicine in the form of hydro-chlorate. It is used locally in powder or solution to relieve pain. It is a strong local anaesthetic. The ordinary dose when used as medicine is from 1/4 to 1/2 grain, and is very unstable and treacherous in its effects. Some patients will tolerate large doses while in others small doses produce unpleasant effects. Deaths are recorded from the use of 1-7 to 1 grain. CHLOROFORM:--"Chloroform is an anaesthetic, and death is often caused by a few inhalations. The dose internally is from 3 to 20 minims. It is not much used in medicine, except to control pain, and produce sleep. It is inhaled to produce mild slumber, or complete insensibility in surgical operations. Death may come suddenly, and without warning, at any time during its administration. CHLORAL:--"Chloral, or hydrate of chloral, is an hypnotic. It is of but little value in medicine, except to control nervousness, and produce sleep. The dose is from 15 to 30 grains. It should be administered with caution, and only by the physician. It is made by passing chlorine gas through pure alcohol, and gets its name from the first syllables of the two words, chlorine and alcohol. It produces death by inhibition of the heart's action, and by paralyzing the pneumogastric nerve.
