Refrigeration therefore is necelTary to the confervation of the natural Heat. Plants are refrigerated by the ambient Air, and by Aliment: their natural heat is extinguifhed by exceflive Cold, and dried up by exceffive Heat* Animals which live in the Air, or in the Water, are re¬ frigerated by the. Air or Water, fome by breath¬ ing, others without.
• Cap. 2 3, 24. c Death., according to the extinflion of Na¬ tural Heat, is two-fold, violent or natural 3 violent, when the Caufe is extrinfical 3 natural, when the Principle thereof is in the animate Creature. For that part whereon Lifedepend- eth (the Lungs ) is fo ordered by Nature, that it cannot perform irs Office for ever. Death therefore cometh from defeH: of heat, when througirwant of Refrigeration the Radical Hu¬ midity is confumed and dried up. Refrigerati¬ on faileth naturally, when by progrels of time the Lungs in Creatures that have Breath, the Gills in Fifties grow fo hard that they are un¬ apt for Motion.
dCrf;>.25^ (j Old Men die ealily, as having but little natural heat and without Pain, becaufe their diflolution comes not from any violent affeffion. . e The Lives of living Creatures, as well of
%'brevitcatA fanie, .as of diversfpecies, differ in length 3 the longeft Life, moft commonly, is that of Ibme Plants, as the Palm and Cyprefs 3 that of Creatures which have blood, rather than the Bloodlefs 3 that of Terreftrial Creatures rather than the Aquatile : That of thofe which have great Bodies, as of Elephants, rather than thofe of little.
_ f The caufes of long Life are firft the quan- f cap. 5. .tity and quality of the vital Moifture," if it be much and fat, not ealily dried up nor congeal’d. Secondly, Natural Heat, which fuffereth not * that Humour to be congealed. Thirdly a due proportion betwixt this heat and that Moifture. Fourthly, fewnels of Excrements, for Excrements are contrary to Nature, and fometimes corrupt Nature it felf, fometimes a part.
Salacious Creatures, or Laborious, grow foon old by reafbn of Exliccation. For the fame reafon Men are Ihorter lived than Wo¬ men, but more a£five..
In hot Countries animate Creatures are larger and live longer than in cold. Thofe Animals which have little or no Blood, either are not at all produced in the Northern parts, or foon die.
Both Plants and Animals, if they take not Aliment, die; for the Natural Heat when the aliment faileth, confiimeth the matter it fel^ wherein it is, the Vital Moifture.
Aquatile Creatures are fliorter Liv’d than the Terreftrial, and the Bloodlefs than thofe that have Blood, becaufe their Humidity is more waterifh, and confequently more apt to bs congealed and corrupted.
g Plants live long, as having left of water- g cap. 4. ifh moifture, which therefore is not fo apt to be congealed. The largeneft of the upper parts as well in Plants a^ Animals, is a fign of long Life, becaufe it argues much natural heat. The upper part of a Plant is the Root, not the Boughs.

WE come next to the Moral part of Philofophy, including E- thick^Peconomick., and Politick. Of the firft,we have ten Books of Ariftotle\ written ( to his Son) Wichomachus., two iBooks call’d Eis great E- thick-., one of Virtues. Of Oeconomick.pNO Books; of Politick §ight. We (hall not have recourfe to thele for an account of his DoGrine in this kind, being furnifhed by Stobms with a fum- mary of what he and the reft of the Peripate- ticks afferted in Morality.
Ethick a (faith he) is fo called aVo tb Uvs, from Cufom., tor thofe things, the Principles and Seeds whereof we receive ftom Nature, are to be perfefted by Cuftom and right Infti- tution. Hence Ethick pertaineth only to Living

Of the Soul^ one part is Rational., the oth.er Irrational'., the rational part is Judicative irrational Appetitive ; of the rational that which is Theoretick, converfant in divine things,is cA‘ led. Science that which is PraUick, converfant in Humane Aftions, is called Qouncil.oiAie lat¬ ter, one part is eoncupifcible, another irafciblei In like manner Virtue is twofold, rational and irrational,conlifting in Theory andPraftice.
