Hardne , 1.0; specific gravity, 155; luster, vitreous; colorle or white; odor, aromatic; soluble in water. Composition: Carbon, 407; hydrogen, obtained by leaving a solution of succinimide and barium hydrate in equivalent proportions to evap- orate over oil of vitriol and recrystallizing several times from weak alcohol.
