This liquid is much used in Europe, but less than ether in this country, as an anaesthetic, by being breathed to annul the pain of surgical operations. It is more dangerous, by far, than ether or nitrous oxide, in this mode of employment; and, of course, it should never be taken or given in this way by an unprofessional person. Symptoms of chloroform poisoning are those of stupor, from which the patient cannot be roused. This may be preceded by signs of great irritation of the stomach; as chloroform is very pungent and heating when swallowed. Treatment requires an emetic at once (see Aconite, Treatment) ; and then, as there is no chemical antidote, dashing cold water on the face and chest, and, if it can be obtained, the galvanic battery ; as a last resort, artificial respiration.
