And besides, that neither
the Spirit of Vitriol, nor that of Soot is any thing White; And, besides
also, that as far as I have observ'd, most (for I say not all) of the
Empyreumatical Oyls of Woods, and other Concretes, are either of a deep
Red, or of a Colour between Red and Black; besides this, I say, 'tis very
remarkable that notwithstanding that great Variety of Colours to be met
with in the Herbs, Flowers, and other Bodies wont to be Distill'd in
_Balneo_: yet (as far at least as our common Distillers Experience
reacheth) all the Waters and Spirits that first come over by that way of
Distillation, leave the Colours of their Concretes behind them, though
indeed there be one or two Vegetables not commonly taken notice of, whose
Distill'd Liqours I elsewhere observe to carry over the Tincture of the
Concrete with them. And as in Distillations, so in Sublimations, it were
worth while to take notice of what comes up, in reference to our present
scope, by purposely performing them (as I have in some cafes done) in
conveniently shap'd Glasses, that the Colour of the ascending Fumes may be
discern'd; For it may afford a Naturalist good Information to observe the
Congruities or the Differences betwixt the Colours of the ascending Fumes,
and those of the _Flowers_, they compose by their Convention.
