THis (anon folveth the knot and difficulty in the Operation of Intenerating by the 
Detention of the Spirit: for if the spirit not fying forth waftcth all within,there 
| is nothing gotten to the Inteneration of the parts in their fubfiftence, butratherthey are | © 
diffolved and corrupted. Therefore together with the Detention the Spirits ought to | - 
be cooled and reftrained, that they may not be too a¢tive. 
Canon X, Ca) ba 
‘He heat of the Spirit to keep the body frefh and green, ought to be Robult, net 
Eager. eer 
The Explication, 
: 
Lfo this Canon pertaineth to the folving of the knot aforefaid, but it is of a 
much larger extent, for it fetteth down of what temperament the heat in the 
body ought to be for the obtaining of Long life. Now this is ufeful, whether the 
Spirits be detained, or whether they be not. For howfoever the heat of the Sperets 
muft be fuch, as it may rather turn it felf upon the hard parts than wafte the foft; 
for the one Deficcateth, the other Intenerateth. Befides, the fame thing is ayailable 
to the well perfecting of Affimilation; for fuch an heat doth excellently excite the fa- 
culty of Affimilation, and withall doth excellently prepare the matter to be Affimi- 
lated. Now the properties of this kind of feat ought to be thefe. Firft, that it be 
flow, and heat not fuddenly: Secondly, that it be not very zutenfe, but mederate : 
Thirdly, that it be equal, not zacompefed, namely, intending and remitting it felf: 
Fourthly, that if this heat mect any thing to refift it, it be not eafily fuffocated or lan- } 
guith. ‘This operation is exceeding fubtil,but feeing it is one of themoft ufeful, it is not 
tobedeferted. Now in thofe Remedies which we propounded to inveft the fpirits with 
a Robust heat, or that which we call operative, not ‘Predatory, we have in fome fort fatif- 
fied this matter. 
Canon XI. 
The Condenfing of the Spirits ia their Subftance % available to Long life. 
The Explication, ! 
af? His Canon is fubordinate to the next precedent ; for the Spirit condenfed receiveth’ 
all thofe four properties of heat whereof we {peak ; but the ways of Condenfing 
them are fet down in the firft of the Ten operatious. . 
by Canon XII. | 
He Spirit 2 great quantity haftaeth more to flying forth, and preyeth upon the bady 
more, than sn {mall quantity, 
ig ba Bs The Explication. 
THis Canon is clear of it felf, fecing mere Quantity doth regularly imcreafe virtue. 
~ Anditis to be feen in flames, that the bigger they are, the {tronger they break forth, — 
and the more f{peedily they confume. And therefore over-great plenty or exuberance | 
of the fpirits is altogether hurtful to Long life ;_neither need one wifh a greater ftore | 
of {pirits than what is fufficient for the fun@ion of life, and the effice of a good Res | 
paration. 
Canon XIII. ee a) 
de Spirit equally aifperfed maketh lei hafte to fie forth, and preyeth lefs upon the body, | 
than unequally placed. rN, Ft 
The Explication. 
No& onely abundance of {pirits in refpeét of the whole is hurtful to the Duration 
of things, but alfo the fame abundance unevenly placed is in like manner hurtful 5 
and therefore the more the {pirit is fhred and inferted by {mall portions,thelefs it prey- § 
eth; for Diffolution ever beginneth at that part where the {pirit is loofer. And theres # 
fore both Exercife and Frications conduce much to long life, for Agitation doth fine- 
lieft diffufe and commix things by fmall portions, |, SNe tae Sa 
‘Canon XIV.- Se 
He inordinate and fubfultory motion of the {piritsdoth more haften to going forth, and | 
doth prey upon the body more, than the conftant and equal. oN
