cncrease it by degree?, until the vehemency of the heat, doth nuke the vapors hiss,as it were ready tc break the Pipes, as they run tborow them - so they wiil be elc-,vat ed thorow the retorted Pipes, and leave the phlcgmatick water in the lower Ves-sel j till pasting through the cold Pipe , they be condensed into Liquor, and falldown into the Receiver. If the water do consume away in the boyling , pour inmore being first warmed, thorow a little Pipe which the Pot must hare on one sidewith a Spiggec to it, for this purpose: but be sure to stop the Spigget in very close,that there may be no vent. Afterwards, separate the OyI from the Water, sublimeand purifie it in another V flel. Of all the Instruments that ever I saw, not any oneextractrech a greater quantity of Oyl,*nd with lpss labour and industry then this. Thusyou may without any fear of burning, draw Oyl out of Flowers, Leaves, spites,Gums, and Wood with the vehementest fires ; as also out of juniper and Laurel*Berries.

The Description os a Dcscexdatory whereby Oyl is extmfted ly Descents

I Cannot refrain from discovering here an Instrument found out by my own pri-vate experience , which I hope wiil be of no small profit to the Ingenious, bywhich they may draw Oyl out of any the least things without any scat of bu ning.For there arc many tenuous, oy ly Flowers, as of Rosemary and Juniper , and otherthings, as Musk, Amber,Civet, Gum,and fhch-like t out of which may be drawn Oylsvery sweet and medicinable : but they are of so thin a substance , that there is agreat hazard of burning them, when they are forced by the heat of the fire, withoutwhich, net, her sac things will be elevated,nor Oyl extracted. Therefore to temedythese inconveniences,I have invented an Instrument, by which Oyl shall descendwithout any labour or danger of burning. Let a Vtflelbemade of Brass,in the formof an Fg°, two foot high , and of the fame breaoth : let it be divided towards thetop, of which the upper par, must serve for a cover, and be so fitted to be receivedinto the lower part. chat the joynts may closely fall ia one another, and be exactlystopt. In the lower pare, towards the middle , about half a soot from the mouth;let there be a Copper-plate fitted, as it were the midriff ; so that it may easily beput and taken rut: in w>Tch must be made three hollow places to receive the bot-tom of three retorted V ssels, the rest of the plate must be pervious, that the boyl-ing Water and hot Spirits may have passage to rife upwards. Out of the sides ofthe Vessel there must be three holes, through the which the necks of the Retortsmay pass, being glued and fastned to their Pipes with Flax, and tied with Fillets ofBladders: so that not the least Air, mnch less any Water may flic out. Whenyou prepare to work, fill the Glass-Retorts with the things you intend to stillthrust the necks thorow the holes outward, and lay their bodies in the preparedhollow ness of the cross-plate, somewhat elevated. If there remain any void spacebetween the necks, and the tides of the holes they pass through, stop ic with Flax,and tie ic about with Fillets of Bladder, and fill the Vessel with with water, whhinthree fingers up torhecrols-plate, The Vessel, being covered, and the joynts wellstopt and glued , and bound about 5 so that the force of the vapours arising, maynot buVf it open, and scald the Faces of the by-standers, kindle the fire by degrees,until it become very vehem-nr: then wil the vapors make a great nose, almost sussi-ci nt to terrific one, and first Water , then Water and Oyl will distil out. I can-not contain my self from relating also another Instrument invented for the samepurpose. Make an oval Brass-Vt ssel, as I advised before, with a hole bored thorowthe bottom ; to which ftsten a pjpe that may arise up co the mouthof the Vessel, lecthe mouth of it be Wide, like a trumpet or tunnel - so that the long neck of a Gourd-(ilass miy pass through the Pipe of it, and the wide mouth of the Vessel under, maybv degrees receive the swelling parts of the neck. Adapt a cover to this Vessel that itmay be close stopt and lured as we said before. You must make a Furnace on pur-pose for this use r for the fire most not be made in the bottom, bur about the Vessel.
