Research Facts
Dr Ralph and Mrs Olga Crawford donated their extensive Canadian dental collection to the DCF to create the museum in 1997; further donations were received while Dr Crawford was Curator Emeritus at the Dental Canada Museum until its closure in 2008; this item was donated by Dr. Norman Ironstone from Ottawa, Ontario; Somnoform was a general anaesthetic made from 60 parts ethyl chloride, 35 parts methyl chloride, and 5 parts ethyl bromide; it was invented by Georges Rolland, director of the dental school at Bordeaux, in 1901; the anaesthetic had a very low boiling point, and turned to gas immediately upon contact with air; it had to be used with a special inhaler or, originally, with a piece of cloth with paper and cotton batting inside; one of its virtues was the fact that a patients breathing stopped before their heart stopped beating, so dentists could monitor their patients breathing in case of problems; it was claimed to be better for minor surgery than nitrous oxide because of its longer anaesthetic time, and better to use before ether or chloroform; while the instructions claimed it was the safest of all anaesthetics, a few deaths did occur, and its use was fairly short-lived
