Oil of yellow sulfur and some of its virtues.
[Drawing on page.] Take yellow sulfur and break it up coarsely. Then put it in a little vessel, as you see in the drawing, and if you have too much sulfur you will need to do this several times because this does not make more than one ounce per pound of sulfur. Put the vessel in the center of a glass bowl, as you see. Put on its glass cap, luted below the thickness of a thumb, or a large funnel that receives all the fumes so that nothing is lost. Then start the fire under the sulfur with a candle. The cap should not touch the bowl by the distance of half a finger and the vessel should not touch the bottom of the bowl so the oil that falls out does not touch it. If it does, it will dry up and you will have nothing. Set it on a little piece of glass and in this way you will be able to collect it. You can lift up the cap when you want to kindle the fire and then lower it and hang it on a nail or tie it with twine. Heat it very slowly and the oil will fall down and you can collect it, little by little. Save it in a large glass bottle. Do it well so that nothing escapes as gas and in this way you will have made oil of sulfur, true, perfect, pure and also simple to make and it meets every comparison. Using it will bring you honor. I put here below for you some of its tested virtues. Viz.
First. For one who has epilepsy, give a little of this oil to drink with a decoction of peony and betony. It will help greatly in this illness.

Another.
For one who has lost his appetite, give it to drink with water of wormwood and it will help him greatly.

It cures all sores, old and new, by putting some of the oil in wine in which has been boiled powder of
querzola
, that is ground pine, and powdered burnet saxifrage, greater comfrey root, St. John's wort, leaves of myrtle, centaury and powdered acorns. Wet cloths in the boiled liquid with the oil and put them on old or new sores and soon they will be cured.
