JtfMWj thatare Benedict, as ftrong Purgers, as thole thatare nor without 
| lorne Malignity. 
Purging Medicines ; for the mod part, haue their Purg&tine Vertue 
in a fine Spirit; Asappearethby that they endure not boiling, without 
much ioflc of Vertue. And thereforeit is of good vfe in Pbyfyke, ifyou 
can retaine the Purging Vertue, and take away theVnpleafant tafte of 
the Pnrger , which it is like you may doe $ by this courfe of Infttfwg oft, 
with little ftay. For it is probable, that the Horrible andOdious Tafte, is 
the Groftcr part. 
Generally, the working by Infttfim, isgrolfe andblinde, except you 
fudUrv thelfliiingof the leuerall Parts of the Body, which ofthem Iftlie 
more fpeedily ,and which moreflowly; And fo by apportioning the time 
can take and ieaue that Quality, which you delire. This to know, there be 
two wayes 5 The one to try what long ftav, and what fhort ftay workerh, 
as hath beene faid; The other to try in Order, the fuccseding Jnfufion of 
one and the fame Body,liiccefliuely, in feuerall Liqueurs. As for example; 
Take Orenge Pils, or Rofc-Mary % ox. Cinnamon, or what you will ; And let 
them infuje halfe an houre in water: Then take them out, an dLijafe th em 
againe in other Water ; And fo the third time * And then tafte and 
eonliderthe Fir ft Water, the Second, and the Third : And you willfinde 
them differing, notonely in Strength and Weaknefle, butotherwife in 
Tafte, or Odour • Foritmay bee the Firft Water will haue more of the 
Scent, as more Fragrant • And the Second more of the Tafte,as more Bit¬ 
ter or Biting, &c. 
Infafionsi n Aire, (for fo we may well call 0 deters) haue the lame dluer- 
fities with Infttfeons in water • In that the feuerall Odours (which are in one 
Flower, or other Body) ifiue at leuerall times ; Some earlier, fome later: 
So wee finde that Violets* woodbines^ Strarcheries, yeelda pleafing Scent, 
thatcommeth forth firft 5 But fooneafter an ill Scent, quite differing from 
the Former; Which is caufed, not fo much by Mellowing, as by the late 
j iftuing of the Groffcr Spirit. 
As wee may delire toextrad the fineft Spirits in fome Calcs • So wee 
| may defire alio todifeharge them (as hurtfull) in fome other. So Wine 
I burnt y byreafonof theEuaporatingof the finer Spirit, enflameth lefte, 
and is beft in Agues■: Opium leeleth lome of his poifonous Quality, ifit be 
j vaporated out, mingled with Spirit of Wine, or the like: Sean leeleth forae-

i things thatare of too high a Spirit, you werebetter powre oif the firft l%- 
after a fmall time, and vfe the latter.

Skin of water without : And it feemeth fomewhat ftrange, that
