    ^he crude ether. It turns acid with age, and should not be kept long. It is a constituent of Mist. Glycyrrhizse Co. (3 per cent.). Dose, _:5ss-^^ss. Its in- compatibles are Potassic Iodide, Ferric Sulphate, Tr. Guaiaci, Tannic and Gallic Acids. AncBsthetic Mixtures. Nussbaum's has—Ether 3 parts, Chloroform i, Alcohol i. Vienna General Hospital uses—Ether 9, Chlorotorm 30, Alcohol 9. The Vienna Mixture,—Ether 3, Chloroform i. Committee of Medico-Chirurgical Society of London (1864) pro- posed—Ether 3, Chloroform 2, Alcohol I. Physiological Action of Ether. Ether is anodyne, antispasmodic, diaphoretic and anthel- mintic ; a cardiac and cerebral stimulant, an anaesthetic, and a narcotic poison. Given internally, it stimulates the secretions of the stomach, salivary glands and pancreas. On the cerebrum and the motor and sensory nerves its action is similar to that of alcohol, but more prompt and less protracted. It is eliminated rapidly, chiefly by the lungs. Externally it is a powerful refrigerant and local anaesthetic; also rubefacient when rubbed into the skin. Inhaled Ether produces at first faucial irritation, a sense of strangulation and cough; then a stage of excitement (cerebral intoxication), in which the face is flushed and the respiration and pulse are accelerated. A tetanic convulsive sMge generally fol- lows, the face being cyanosed, the muscles rigid, and the respira- tion stertorous. This soon subsides, and complete insensibility is established, the muscles being then relaxed, the reflexes abolished, and the cerebral functions suspended, the lower centres in the medulla carrying on the processes of respiration and circula- tion. If the inhalation be continued, these also become paralyzed, death usually resulting from slow paralysis of respiration, the heart pulsating long after breathing has ceased. [Chloroform usually paralyzes the heart.] If the inhalation be discontinued before the lower centres are affected, the patient gradually emerges from the condition of insensibility, and, as the narcosis subsides, vomiting is usually experienced. Compared with Chlo7'oform. Ether is less irritant than Chloroform to the mucous membranes when swallowed, but its vapor is more irritant to the air-passages. It is more of a general stimulant, and less depressant to the heart and circulation. It does not clot the blood. Its vapor is very inflammable, less pleasant to inhale, slower in action, has a longer stage of excitement, and a less profound narcosis, and causes a greater degree of vomiting. It is much less dangerous than
