ANILINE COLOURS 



tionod are not now in use as dyes, either because they are too expensive, or because 

 their use is inconvenient, requiring too complicated a treatment or rare chemicals to 

 fix them upon the goods, or because they have been superseded by dyes of better 

 quality. Several colours, black especially, are usually produced on the fibre of the 

 goods by printing them with various salts of aniline and rosaniline, and then with 

 salts of copper, chlorates, &c. Most of the dyes called aniline-blacks give, when 

 dissolved, deep green solutions. Of those to which the formulae are not given, the 

 chemical formula; arc not as yet known, or they have not been given by those works to 

 which I have resorted on the subject. The derivatives of aniline and toluidino are 

 given together, as the two are with difficulty separated from each other, and in course 

 of manufacture the separation is never attempted."
