Chloral may be given in place of chloroform, but the latter is best; the dose of chloral should be, at least, half a drachm, and if no effect is produced in half an hour, then doses of 20 grains should be given at intervals of a quarter of an hour.

If neither chloroform nor chloral is at hand, the juice from a recently-smoked pipe may be diffused in a little water and a few drops injected subcutaneously, and the effect watched. If there is a marked improvement the treatment may be persevered in.

Bromide of potassium in combination with chloral has been recommended.

Nitrite of amyl inhalations are said to be of use.

Curarine in a subcutaneous dose of one-third of a grain is antagonistic so far that it paralyses the voluntary muscles.
