LEt some quantity of odorate Virgin-wax be melted, and mixed with a third part of brayed Flint-stones, or sand purged from filth. When the mixture is cold, let it be put into a straight Am∣pulla, covered with a rostrated capitel; let its fire be at first slow, afterwards more luculent, that the Oyl may be educed.
We have selected this as the shortest and easiest of all those wayes by which this efficacious Oyl is educed; yet if any would make it otherwise, let him project the odorate liquefied wax into water eight or ten times, alwayes agitating it with his hands; and then put it in the Retort, and educe its Oyl by fire, or hot ashes. Now if you would not have it so spisse (for it is of the spissitude of Butter) iterate its distillation twice or thrice, and it will be liquid and fluxile.
An Oyl may be after the same manner educed out of the Gumme Elemni, most accommodate for the cure of Wounds; yea, Oyl may after the same manner be educed out of Fats, by the addition of brayed Flint, Sand, or broken Bricks.
