Proceedings of the Twenty-Fourth Annual Convention of the Association of Official Agricultural Chemists held at the Jamestown Exposition, Norfolk, Va., October 9-11, 1907. nalysts took part in the work, contributing a valuable collectionof opinions and experiments. The generous portion of time and labor given bythem shows a deep interest in every attempt at the improvement of our analyt-ical methods. Over 420 separate determinations of nitrogen and about 120 ofmoisture were made, some according to strictly prescribed methods and othersaccording to methods deviating in several respects from these. The list ofanalysts participating in this work may be found in the table of moisture 36 determinations. The samples were taken from a quantity of material tlior- oiiglily mixed, bottled, and sealed: it is believed that tliey were as nearly uni-form as tbey could be made, and fully secured from cliange in moisture contentor other change. The following table shows the percentage of moisture foundby the several analysts and the methods pursued by each: Table I.—Results of cooperative work on the determination of moisture incorn meal and cotton-seed meal.
