Abstract
Mr. Joseph P. GAZZAM,Germiston, Transvaal, So. Africa (communication to the Secretary*) :—About fourteen years ago, in southeastern Missouri,I used a method for the wet determination of lead which closely resembles the modified sulphate-chromate method described by Mr.. Guess. The principal difference, however, is, that after dissolving the lead chromate in hydrochloric acid, the chromic acid is determined by means of a standard solution of ferrous sulphate. The method, which I believe is still in use in southeastern Missouri, was found to be convenient and accurate for the determination of lead in the ores and various products of the mills and furnaces in that district, but it was never used for complex ores. A number of determinations of lead in mill-tailings were made in the year 1891; a few of these results are given in Table I. Table I.—Determinations of Lead in MilL-Tailings by Wet Assay.
