The Explication, , : 
"1 He nature of the Sspzrtts isasthe uppermoft wheel, which turneth about the other 
wheels in the body of man, and therefore in the Jutentiow of Long life, that ought } 
to be firft placed. Hereunto may be added, that there is an eafier and more expedite 
way to alter the fpzrzts, than to other Operations. Forthe Operation upon the SPirsts is 
| two-fold: the one by 4/émsents,which is flow, and, asitwere, about; the other, (and 
thattwo fold) which is f{udden, and goeth directly to the {pirits, namely, by Vaponrs, 
ot by the 4ffections. ; 
Canen XX. 
Juices of the Body hard and rofcid are good fer Long life. : ’ 
The Explication. 
He reafon i: plain, feeing we fhewed before, that bardthings, and ofl) or rofeid are 
hardly diffipated : notwithftanding there js difference, (as we alfo noted in the 
tenth operation ) That juice fomewhat hardisindeed lefs diffipable, but thenit is withal | 
lefs reparable + therefore a Conventence is interlaeed with an /nconventence, and for this 
caufe no wonderful matter will be atchieved by this. ~ But rofcid juscé will admit both 
aperations ; therefore this would be principally endeayoured.

V Aatfoever t of thin parts to penetrate, and yet hath no Acrimony to bite; begatteth 
Rofcid Juices. . if! 
The Exphcation, 
His Cano# is more hard to praétife than to underftand. For it i manifeft, what- 
foever penetrateth well, but yet with a fing or tooth, (asdo all fharp and four 
things ) it leaveth behind it wherefoever it goeth fome mark or print of drinefs and 
cleaving, fo that it hardneth the j#tces, andchappeth the parts: contrarily, whatfoever 
things penetrate through their shsmne/s merely, as it were by ftealth, and by way of in- 
finuation, without violeace, they bedew and water in their paflage. Of which fort we | 
have recounted many in the fourth and feventh Operasions,

Limentation from without, a9 leaft forme other way shan by the Stomach, 4s mos? pro- f 
fitable for Long life, if s¢ can be done. | ee ats? 
The Explication. . . 
E fee that all things which are done by 2Y s#rssion, ask a long time, but thofe which } 
are done by embracing of the lske (as it is in Jnfmfions) require no long time. And -f 
therefore Alimsentation from without would be of principal ufe,and fo much the more, 
becaufe the Faculties of Concottion decay inoldage: fo that if therecould be fome auxi- | 
liary 2 utritéons, by Bathings, Unttions, or elfe by Chfters, thefe things in comjunGtion | 
| might do much, which fingle are lefs ayailable. ‘
