- n. A product obtained in the distillation of petroleum. It is probably the most volatile fluid known, and one of the very best for use in producing intense cold; when atomized it gives a temperature of—9°C. Its specific gravity is .603 to .629 (105° to 95° B.); it boils at 18° C. It is used as a local anesthetic. Also rhigoline.
The moment the pumping of the ether or rhigolene ceases, the tissue operated on ceases to be frozen, so ephemeral is the degree of the cold obtained by these means.
Ether and rhigolene have been employed with some degree of success, but both are expensive, and they cannot be used in the presence of artificial light, because of danger of explosion.
Albumen of egg, one drachm; rhigolene, four ounces; oil of peppermint, two ounces; colodion and chloroform, each one ounce.
A person's finger may be frozen in one minute's time, by throwing upon it a constant, fine spray of rhigolene or sulphuric ether.
