that / urgetb, and hath neither of the firft two Manifeft Qualities ; it is to 
bee held iufpefled, asakindeof Potfon ; For that itworketh either by 
Corrtfson Dr bv a Secret Malignity anci Enmity to Nature : And there¬ 
fore fitch Medicines are warily to be prepared, andvfed. The Quantity of 
I that Which is taken, doth alfo caufc Purging •' as wee fee in a great Quan- 
| tity of Aew Milke from the Cow; yea, and a great Quantity of Meat? For 
| Surfeis many times tume to Purges y both vpwards, and downwards, 
j Therefore we fee generally j that the working of Purging Medicines^ com- 
j merh two or three houres after the Medicines taken 5 For that the Sto- 
' made firftmaketh aproofe, whether it can concoct them. And the like 
happencth a Iter Surf as 5 Or Mtlke in too great Quantity. 
A kcml\ Caufe is Mordication of the Orifices of the Parts • Efpecial- 
ly of the Mefenlery Heines ; As it isfeene, that Salt, or any fuch thing 
that is tliarpe and biting, put into the Fundament, doth prouoke the 
Part to expel I 5 And Mnftard prouoketh Sneezing : Andany fharpe 
Thing to the Eyes, prouoketh Teares. A nd therefore wee fee thatalmoft 
all Purgers haue a kiride of Twitching and Veliication , befides the Griping 
which cofi/raeth of win.de. And if this Mordtcation bee in an ouer-hi^h 
Degree, it is little better than the Corrofion of Peifon ; Andit commedi 
to pafie fbmetimes in Antimony 5 Efpccially ifit be giuen, to Bodies not 
repleat with Humors 5 For where Humors abound^ the Humors due 
the Parts. 
The third Can felt Attraction : Fori doe not deny, but that Purging 
Medicines haue in them a dired Force of Attraction ; As Drawing Plafters 
haue in Surgery : And wee fee^r, or Betenybrttfed, Sneezing-powder, 
and other Powders or Liquors (which the Phyfitians call Errhines,) put in¬ 
to the Nofe, draw Flegme, and water from the Head 5 And fo it is in A- 
pophlegmatifwee , an dGargarifmes, thafcdraw the Rheiime doWne bv the 
Pallar. Anci by diisVertue, nodoubt, feme Purgers draw more one Hu¬ 
mour, and fome another, according to the Opinion receiued : As Ru- 
barbd raweth Cholleig Sean Melancholy; Agaricke Flegme ; &c.But vet, 
(more or leHe) they draw promifcuoully. And note alfo. that befides 
Sympathy, feetweenethe Purger and th e Humour, there is aifo another. 
Caufe, why fom z CMedicincs draw fome Humour more than another.* 
And iris, for t hat fome Medicines worke quicker than others : Andthev 
that draw quicke, draw onelv the Lighter, and more fluide Humours '; 
they that draw flow, worke vpon the more Tough, and Vifeous Hu¬ 
mours. And therefore Men mufi beware, how they take R it barb, and the 
like, alone, familiarly ; For it takethonely the Lighteftpartofthe Hu¬ 
mour away, and leaucth the Mafic of Humours more obftinate. And the 
like may bee faid of Worms-wood, which is fo much magnified. 
The fourth Caufe is Flatuofity : For Wind ftirred moueth to expel!: And 
wee findethat (in effect) all Purgers haue in themaraw Spirit, or Wind? 
which is the Principall Caufe of Tortumm the Stomade, and Belly. And 
therefore Purgers koft (molt of them) the Vertue, by Decodion vpon 
the Fire ; And for that Caufe are giuen chiefly inlnfufion, Iuvce, or 
Powder. ' '
