you fhall fee the Wine, as it were, in a fmall vein, rifing through the Water. 

 For handfomnefs fake (becaufe the Working requireth fome fmall time) 

 it were good you hang the upper Glaf upon a Nail. But as foon as there 

 is gathered fo much pure and unmixed Water in the Bottome of the Lower 

 Glaf, as that the Mouth of the Upper Glaf dippeth into it, the Motion 

 ceafeth. 



Let the Upper Glaf be Wine, and the Lower Water 5 there follow eth no 

 Motion at all. Let the Upper Glaf be Water pure,the Lower Water coloured^ 

 or contrariwife -,there followeth no Motion at all. But it hath been tricd,that 

 though the Mixture of Wine and Water, in the Lower Glaf, be three parts 

 Watered, but one Wine - 7 yet it doth not dead the Motion. This Separation 

 of Water and Wine appeareth to be made by Weight 5 for it mull be of Bodies 

 of unequall Weight, or elfe it worketh not And the Heavier Body muft ever 

 be in the upper Glaf. But then note withall, that the Water being made 

 penfible, and there being a great Weight oiwater in the Belly of the Glaf, fu- 

 ftained by a fmall Pillar of Water in the Neck of the Glaf 5 It is that,which 

 fetteth the Motion on work ; For Water and Wine in one Glaf, with Ions 

 ftanding, will hardly fever. 



This Experiment would be Extended from Mixtures of feverall Liquors, 

 to Simfle Bodies, which Confift of feverall Similiar Parts : Try it therefore 

 with Broyn or Salt-water^ and Frefh-water ? Placing the Salt-water (which is 

 the heavier)in the upper G la\s^ And fee whether the Frefh will come a- 

 bove. Trie it alfo with Water thick 8ugred,znd Pure Watered fee whether 

 the Water which cometh above, will loofe his Sweetnefs : For which pur- 

 pofe it were good there were a little Gock made in the Belly of the up- 

 per Glafs. 



IN Bodies containing Fine Spirits,, which do eafily dhTrpate, when you 

 make Infufions, the Rule is A fhOrt Stay of the Body in the Liquor recei- 

 ved the Spirit-, And a longer Stay; confoundeth it- becaufe it draweth 

 in forth the Earthy Part withall 5 which embafeth the finer. And therefore 

 liquor '^and'") it is an Errour in Why fit tans, to reft fimply upon the Length of ftay, for en- 



Air. '~ •'■

f creafing the venue. But if you will have the Iwfu$on ftrong, in thofe kind 

 i of Bodies which have fine Spirits, your way is, not to give Longer timeout 

 ' to repeat the Infufion of the Body oi rner. Take Violets, and infufe a good 

 Pugill of them in a Quart of Vineger Let them ftay three quarters of an 

 hour,and take them forth ^ And reirefh the Infufion with like quantity of 

 new Fiolets,teven times And it will make a Vineger fo frefti of the Flower, 

 as if a Twelve moneth after,it be brought you in a Saucer, you {lull fmell it 

 before it come at you . Note,that it fmelleth mor e perfectly of the Flower, 

 a good while after, than at firft. 



This Rule, which we have given, is of lingular ufe, for the Preparations 

 of Medicines, and other Infufwns. As for Example the Leaf of Burr age 

 hath an Excellent Spirit, toreprefs the fuliginous Vapour of Dusky Me- 

 lancholy, andfotocureMadnefs: But neverthelefs, if theLeafbeinfufed 

 long, it yeildeth forth but a raw fubftance, of no Vertue Therefore I fup- 

 pofe, that if in the Muft of Wine, or Wort of Beer, while it worketh, be- 

 fore it be Tunned, the Burr age ftay a tall time, and be often changed with 

 frefh It will make a Sovereign Drink for Melancholy Paifions. And 

 the like I conceive of Orenge- Flowers, 



Rubarb\m\\ manifeftly in it Parts of contrary Operations ; Parts that 

 purge, and parts that bind, the body:and thefirft lay loofer, and the latter lay 



deeper:
