222 The Riining and Scientific Dregs,
M. Jmannen has discovered a new way of
easily ascertaining whether there exists any
lead in the tin used for tinning culinary vessels
in hospitals. His method consists in this:
Take about five decigrams of scrapings of the
metal to he tested, and boil it in an excess of
nitrie acid diluted with one-third of its weight
of water. When the solution is complete, filter and then pat in a crystal of iodide of potassium. Jf the liqnid contains hut a tenthousandth part of lead, a yellowish precipitate
will he formed, which will not disappear hy the
addition of an excess of ammonia.
