✦ Synopsis

potassium iodide to 16.5 grammes of iodine per 100 Cc. was subject to decomposition. In view of the fact that the U. S. P. tincture of iodine contains 5 grammes of potassium iodide to 7 grammes of iodine per 100 Cc. it was contended that there is insu5aent potassium iodide in ChurchiIl's tincture of iodine to prevent decomposition and, therefore, a preparation which had been made for a time, would upon analysis show a shortage of free iodine.

A search of the literature failing to show any data on the subject, I reassayed an old laboratory sample in order to have facts upon which to base an opinion. Recently, I made another anatysis of this same sample, the results of all analyses being as follows:
