To take the rosanilines as an instance of the rest. Aniline red, magenta, azaleine, rubine, solferino, fuchsine, chryaline, roseine, erythrobenzine, and others, are colouring matters in this group which are salts of rosaniline, and which are all recognised in commerce.
In the reds are rosanilines, toluidine xylidine, &c.; in the blues phenyl-rosanilines, diphenylamine, toluidine, aldehyde, &c.; violets rosaniline, mauve, phenyl, ethyl, methyl, &c.; greens iodine, aniline, leucaniline, chrysotoluidine, aldehyde, toluidine, methyl-anilinine, &c.; yellows and orange leucaniline, phenylamine, &c.; browns chrysotoluidine, &c.; blacks aniline, toluidine, &c.
