N. B. Such a sowre spirit or oyl may also be got by distillation together with the flores, _viz._ thus: If you take pieces of sulphur as big as hens eggs, and cast them one after another into the hot distilling vessel, a sowre oyl together with flores, will come over into the receiver, which must with water be separated out of the flores, and the water abstracted from it again in a cucurbit, and in the bottome of your glass body you will find the oyl, which in vertue and taste is equal to the former, but you get nothing near so much in quantity by this way, and if you do not look for the oyl, you may leave it with the flores, which by reason of their pleasant acid taste are much toothsomer to take than the ordinary ones. To the Courteous Reader. _Thus I conclude this second part; I could have set down more medicinal processes in this Treatise: but having as many as will be a sufficient guide for the distilling of other things also, I thought it good here to acquiesce; and whatsoever hath been here omitted, shall be supplyed in the following parts._ FINIS.
