N.B. But if salt nitre be mixed with sulphur in due proportion, and in the first furnace be cast upon quick coles, then all will be burnt, and a strong spirit cometh over, whose vertue is needless here to describe; but more shall be mentioned of it in another place. _Of the Clissus._ Among the Physitians of this latter age, there is mention made of another spirit, which they make of Antimony, Sulphur, and salt nitre, a like quantity taken of each, which they call _Clissus_, and which they have in high esteem, and not without cause, because it can do much good, if it be well prepared. The inventor, for the making thereof used a retort with a pipe, as was mentioned by the sulphurized spirit of salt nitre, through which pipe he threw in his mixture. And it is a good way if no better be known: but if the Author had known my invention and way of distilling, I doubt not but he would have set aside his, that hath a nose or pipe retort, and made use of mine. The materials indeed are good, but not the weight or proportion; for to what purpose so great a quantity of sulphur, it being not able to burn away all with so small a quantity of salt nitre. And if it doth not burn away, but only sublime & stop the neck of the retort, whereby the distillation is hindered, how can it then yield any vertue? Therefore you ought to take not so much sulphur, but only such a quantity as will serve to kindle the salt nitre, _viz._ to ℔ i. of salt nitre four drams of sulphur: but because Antimony also is one of the ingredients, which hath likewise much sulphur (for there is no Antimony so pure, but it containeth much combustible sulphur, as in the fourth part of this book shall be proved:) therefore it is needless to add so much sulphur unto Antimony, to make it burn, because it hath enough of it self. And therefore I will set down my composition, which I found to be better than the first. Take Antimony ℔ i. salt nitre ℔ ij. sulphur ℥ iij. the materials must be made into small powder and well mixed, and at once cast in ℥ ij. thereof, and there will come over a sulphureous acid spirit of Antimony, which will mix it self with the water, which hath been put before in the receiver; which after the distillation is finished must be taken out and kept close for its use. It is a very good diaphoretick (or sweat provoking) medicine especially in feavers, the plague, epilepsie, and all other diseases, whose cure must be performed by sweating. The _Caput Mortuum_ may be sublimed into flores in that furnace, which is described in the first part. _Of the Tartarised spirit of nitre._ In the very same manner there may also be distilled a good sweat-provoking spirit out of salt nitre and Tartar, a like quantity taken of each, which is very good to be used in the plague and malignant feavers.
