Chymicus rationalis: or, The fundamental grounds of the chymical art

rationally stated and demonstrated, by various examples in distillation, rectification, and exaltation of vinor spirits, tinctures, oyls, salts, powers, and oleosums; in such a method as to retain the specifick virtue of concrets in the greatest power and force. In all which the chymical doctrines are illustrated upon a new hypothesis or spagirick course, composed agreeable to practical philosophy, and the best authority of art, for mysteries treated of by Cartes, Starkey, Sylvius, Glauber, Helmont, Paracelsus, and others, are explicated and exemplarified, ... and so fitted in order for the publick service. In which is contained, a philosophical description of the astrum lunare microcosmicum, or phospheros. Recommended to all that desire to improve and advance profitable truths, such as are real and not hystorical
