Tinned Foods.
Some light is thrown by the lancet upon the mysterious- cases of poisoning by tinned food which from time to time are reported. They are believed to be due to neglect of the caution against tinned foods, that i have been exposed to the air for some time after being opened. The exact manner in which poisonous, substances, tecli-rically known as ptomaines, are generated so rapidly is not known with certainty, but the fact that-they are produced in-strffi* 6 cient quantity to cause very grave symptoms of poisoning hpe^been* brought out in a muUitdde >of r in£ stances. In one well-knoWn^ case the first half of the contents of a tin of lobster-was consumed with no' ill effect, but the rest a few days afterwards proved extremely poisbn ous. It is suggested that as a safeguard manufacturers might label the tins with some such notice as "The contents of this tin are perfectly wholesome when eaten fresh from the tin, and afford good food but the public are advised -not to expose the, contents for any length of timo to the injurious influences of the atmosphere*" -The Lancet writer even goes so far as to suggest that some such warning might be insisted on by the Legislature. , "': .
