Bate.] Distil Vitriol cal∣cin'd from Sand, and separate the Spirit from the Flegm▪ S. A. In strengthning the Ventricle, repressing Fevers, quenching Thirst, allaying Inflamations, &c. it is a Secret. Dose so much as may make the Liquor pleasantly acid, and not set the Teeth on edge.
Salmon.] § 1. In our Pharm. Lond. lib. 3. cap. 11. sect. 78. you have the Colledge's way of distilling this Spirit and Oyl, with our Annotations thereon, which in that respect are enough: but by reason several Men have several ways or methods of doing the same, from whence new Observations may arise, and that they are also equally necessary to be known to the ingenious Physician, we shall take the pains here to relate them. § 2. From Marg-gra∣vius. ℞ Vitriol calcined and poudred lbx. put it into a strong earthen Retort, or a glass one well covered with lute; di∣stil in an open Fire for twenty four hours, so will you have Flegm and Spirit come over together: which by rectifica∣tion you must separate: then change your Receiver, and di∣stil with a Reverberating Fire for twenty four hours more, so will you have a most potent and strong Oyl, which is the Oleum Vitrioli verum Paracel∣si; which being mixt with Water will make an Efferve∣scence. § 3. Now here is to be noted, that in the begin∣ning of this distillation, the Fire ought to be small for the first six or eight hours, this brings off the Flegm: then it ought to be increased by de∣grees to the second and third degree of Reverberation for eight hours more, and then urged for the next eight hours to the fourth degree, so have you Spirit and Flegm in one mass together, which (as I said before) by rectification are to be separated: lastly, for the other twenty four hours, the Fire is continued in that same fourth degree for eliciting the Oyl of Para∣celsus. § 4. From this vehement strong Oyl, by means of Wa∣ter, and other Liquors, a white Substance may be precipita∣ted, which by fusion or melt∣ing will turn into Copper.
