Chemical Monster in Dyed Milk.

Evidence is accruing that the practice of adding artificial coloring matter to milk is Increasing. Samples are commonly met with thus colored to give them a rich but false creamy aspect. The natural color of milk bears no relation necessarily to the amount of cream present. It is very desirable that this practice could be stopped. We believe that annatto is the dye commonly employed and it is fortunate that it is harmless, though that fact does not justify the device. Certain coal-tar dyes have, however, been detected in milk, and among them methyl-orange, or, in chemical nomenclature, the sodium salt of dimethyan-iline-azobenzene-sulphonic acid.
