A two-page 1869 article by Dr. M. Reiman of Berlin on the adoption of aniline dyes in the 1860s. It explains that aniline colors dye wool and silk without mordants, and describes how cotton is prepared by 'animalizing' with albumen or casein, oil mordants, soap, or sumac and gall-nut tannin. It also covers the economy and brilliancy of aniline colors, and their instability compared with indigo and madder.
