![rise to the presence of lead in the product, the firm in question carried out a prolonged investigation with various modifications until a satis¬ factory arrangement was found, before any of the machines were put into use. No serious metallic contamination was found in the samples from the machines in use, but a few machines which gave unsatisfactory results became satisfactory again after thorough cleaning and flushing. Samples of tincture of Iodine again gave evidence of careless dis¬ pensing. Only one was within the Pharmacopoeial limits, although four others were within ten per cent, of the correct figure. The rest ranged from 49.6% deficiency to 15.2% excess of iodine and 36.7% deficiency to 98.7% excess of potassium iodide. Three were made up with denatured spirit in place of alcohol. The glycerine contained slightly more water than is allowed in the Pharmacopoeia specification, and also a trace of iron. Four samples of face-powder were found to contain lead, but the. stocks were very small and were seized. Samples were analysed and reported on to other departments as shown in the following table:— SAMPLES. Water Dept. Electrical Dept. Engineers and Sewerage Dept.
