Experiment XXIII
That Roſes held over the Fume of Sulphur, may quickly by it be depriv’d of their Colour, and have as much of their Leaves, as the Fume works upon, burn’d pale, is an Experiment, that divers others have tried, as well as I. But (Pyrophilus) it may ſeem ſomewhat ſtrange to one that has never conſider’d the Compounded nature of Brimſtone, That, whereas the Fume of Sulphur will, as we have ſaid, Whiten the Leaves of Roſes; That Liquor, which is commonly call’d Oyl of Sulphur per Campanam, becauſe it is ſuppos’d to be made by the Condenſation of theſe Fumes in Glaſſes ſhap’t like Bells, into a Liquor, does powerfully heighten the Tincture of Red Roſes, and make it more Red and Vivid, as we have eaſily tried by putting ſome Red-Roſe Leaves, that had been long dried, (and ſo had loſt much of their Colour) into a Vial of fair Water. For a while after the Affuſion of a convenient Quantity of the Liquor we are ſpeaking of, both the Leaves themſelves, and the Water they were Steep’d in, diſcover’d a very freſh and lovely Colour.
