Abstract

In 1833 Braconnot described a body which he called Xyloidine. This material was obtained by the action of nitric acid on starch. In 1838 Pelonze produced a similar body by treating paper with nitric acid. Although these experiments were conducted several years before those of Soh8nbein, yet we give Schonbein the honor of priority because of bis extensive studies on the new compound "ex­plosive cotton wool". The material was produced by the combined action of nitric and sulphuric acids on cellulose. A patent was granted to him in the United States December 5, 1846, but little attention was paid to the new discovery.
