GREIFF (13, 288).-A formula of a bibromnitrotoluole, had been prepared by Wachendoiff from orthonitrotoluole and bromine. But, being soluble in alkalies, its constitution might be expected to be different from that of bodies of the class mentioned. The author finds that it iR, in fact, bibromanthranilic acid, and calls attention to the remarkable reaction by which oxygen and hydrogen, contained in the nitro and methylgroups, change their places within the molecule during the reaction with bromine.
