Indigo is such a dye, and so are Magenta, Aniline Black, Aniline Violet, picric acid, Ultramarine Blue, and so on. Ultramarine is not, it is true, confined to blue; you can get Ultramarine Green, and even rose-coloured Ultramarine; but still, in the hands of the dyer, each shade remains as it came from the colour-maker, and so Ultramarine is a monogenetic colour.
They are so plentiful that there is no motive to adulterate them, and their use among those of us who are so unwise as to drink anything except water ought to be effectively advocated as supplanting the drinking of beer poisoned with strychnine, whisky poisoned with fusel-oil, and ``French claret'' poisoned with salicylic acid and aniline.
Shoddy treated with aniline dyes can produce effects that overwhelm the colours of the honest old materials which owed their hues to the efforts of the vegetable and the insect. A modern manufacturer is proud when his scarlet shoddy shrieks like a steam siren. Unfortunately some of the managers seem to like the shriek. Stage Meals
There were thus two methods of obtaining aniline from tar, the experimental and the practical. The mixture is gradually introduced into the large cast-iron cylinder into which the benzene has been poured.
Oriental silks are all dyed in the shades of blues, yellow pinks, terra-cotta reds, and brilliant yellows, to be seen in Eastern embroideries worked before the introduction of aniline dyes, and the consequent lapse into Imperial purples and magentas and royal blues. By a judicious use of good colours the same design can be so repeated as to look entirely different.
Having had considerable experience in the use of the alcoholic solutions of aniline dyes for staining bacteria, and having for some months used solutions in glycerine instead, I have come to much prefer the latter. Evaporation of the solvent is avoided, and in consequence a freedom from vexatious precipitations is secured, and more uniform and reliable results are obtained.
Cases of chronic poisoning from the 'als' are not uncommon, and are increasing in frequency. Hypnogen is apparently identical with veronal. All the above-named aniline derivatives are included in Part I. of the scheduled poisons. All parts of the plant are poisonous, often mistaken for parsley.
It was on Christmas morning, 1821, that Faraday first succeeded in making a magnetic needle rotate around a wire carrying an electric current. He was the discoverer of benzole, the basis of our modern brilliant aniline dyes. In 1831 he made the discovery he had been leading to for many years that of magneto-electric induction.
Christmas Eve the Happy Family spent in arranging a round-up camp out behind the house where the hill rose picturesquely, and in singeing themselves heroically in the heat of radium flares, while Luck took his camp-fire scenes that were triumphs of lighting-effects and photography, scenes which he would later tone red with aniline dyes.
The next and most important thing is colour, and it is a great advantage if the dyeing can be done at home. There is a strong and well-founded preference among art producers in favor of vegetable dyes, and yet it is possible to use certain of the aniline colours, especially in combination, in safe and satisfactory ways.
