Abstract
Robert Mauzelius, in the Geological Survey of Sweden (Sveriges Geol. Underseekning), calls attention to a universal defect in the estimation of ferrous iron in minerals and rocks. He finds that a considerable error arises from grinding the rock in the ordinary way to a fine powder, owing to the oxidation of ferrous to ferric iron. If the specimen is reduced to a coarse powder instead of being finely pulverized, a more accurate result is attainable. This source of error has hitherto escaped the attention of analysts.
