Med. Prop. and Action. In doses of gutt. ij. - vj., in mucilage, or on sugar, it is stated to be stimulant, diaphoretic, and emmenagogue. Externally, in the form of embrocation (one part of the Bisulpburet and two of oil), it is stimulant. The vapour, if inhaled, is anaesthetic. Prof. Simpson** exhibited it in about twenty cases, and states that it is certainly a very rapid and powerful anaesthetic. One or two of the patients stated that they found it more pleasant than Chloroform; but, in the majority, it produced distressing and disagreeable visions, and was followed for some hours by headache and giddiness, even when given only in small doses Dr. Snow* also made some experiments with it, and considers that a single deep inspiration of air saturated with its vapour, would produce instant death. On the whole, it appears very inferior, in uniformity of action and safety, to Chloroform. Its smell, that of decaying vegetable matter, is a great objection to its use. (Pereira.)
