Etherum.

Ethyl oxide. Ethylic Ether, sometimes called Sulphuric Ether. (C2H5)2O (Alcohol is C2 H6O).

Clinical.-Bronchitis. Catalepsy. Convulsions. Cough. Delirium tremens. Hiccough. Mania. Meningitis. Nausea. Vomiting.

Characteristics.-Ether is the well-known anaesthetic, and the effects are those observed in patients under the action of its vapour, administered for the purpose of operation, in habitual ether drinkers (of whom there are numbers in Ireland), and on some who have voluntarily experimented with the drug upon themselves. Closely allied to alcohol, it possesses very similar intoxicating properties, produces visions frequently pleasurable, hallucination, and, in some instances, a persistent maniacal condition. Convulsions, spasms, and a cataleptic state have also been observed. Bronchitis is a not uncommon after-result of ether anaesthesia, and for this Belladonna has been observed to be the best antidote. Chilliness is complained of by many. Macfarlan reports the cure of a woman of 60, who had been confined to bed for weeks with severe neuralgia of the head, raised welts on scalp like ridges accompanying the pain. Ether 200 cured quickly.
