​METALLIC, pointed substances are often inadvertently swallowed by children and adults:—in such cases it will be necessary to take large draughts of vinegar, lemon-juice, or other vegetable acids, in order to blunt the points of iron, brass, copper, and other fragments or pins; but never to venture on an emetic. If the metallic bodies introduced by the mouth, have been of a round form, or if they happen to be detained within the Gullet, we refer the reader to that article.
