Show The Nature of Mixture. Led. I. parts of alWatch, were put into'a Clocks or that there were no other ‘Materials wherewith to build an Honfe, then for a Tet or a Ship, For whyfhould Nature, the great Artificer by which all perfect Works are made, be feigned to cram and ram all things into one, Which we our felves look upon as abfurd ? _ whe §. secondly, The Mixture of Principles is diverfifi'd, as by Consyeation, fo alfo by Proportion. That is, bythe divers Quantities, of the feveral Priciples or Parts mixed together. Led. IL. ments,in the molt perfect Mixture of Bodies. It cannot be ; for Principles are Ivemutable, as we have faid. And if it could be, yet it xcedeth not Ch, 2. ¢. 33 to be: forthey are alfo many, and compoundable infinite ways 5 as As if the Quantity of hath been fhewed. So that we have no need to perplex our elves CA- 2+ $ «53 with any of thofe difficulties, that arife from the Doérine of the Ch.3- $.10: Alteration of Elements. tions, Mixture maybe varied innumerable ways. Again, As Mixtureis varied with refpect to the Bodies Mix- ed; fo likewife in refpect of the Mixtureit fel, which Icall the Loca- tion Of Principles, or the Modes of their Conjunttion. Which may be various, as well as their Conjugation and Proportion. Yet are theyall reduceable unto two general Medes: all Bodies, and therefore all Prin*2+ ciples, being mixed either by Mediation, or by Contaét. 8. §. Nowall Contact, whether of Compounds, or of Atomes, can be no other way, than fuch as is anfwerable to their Figures. Where- of, therefore, we can conceive but three general ways, viz. Firf, ByContract ina Point, or {ome fualler part : as when two Atomes meet, which are globular or otherwife gibbofe. Secondly, By Contaté in a Plain: asin the conjunGion of the fides of Triangular or 2D lar Atomes, or otherwife flat. Thirdly, By Contad in a Conca s when one Afome is admitted into the Concave or hole of another 5 as a Spigot isintoa Foffet. The fief? maybe called, Appofttion 5 the fecond, Application, the third, Reception or Intrufton. 9. §. Inthe two laft ways, Atomes may be joyned by Mediation ; but beft ofall the /a?. ceived into the Concav@ to. §. As when the two extreams ofone Atome are reorthe holes of two others, And thefé areall the gezeral ways,whereby we can conceive Bodies to be Mixed together 5 /c. by their various Conjugation, Proportion and Location. So that the Compofition of Atomes, in Bodies 5 is like that of Letters, in Words, What a Thunderclap wonld fach a Word be, whereinall the four and twenty Letters were pack’d up? One therefore is compounded of more, another offewer: this offome, and that of others: and both the Conjugation, Proportion, and Location of Letters is varied in every Word: whereby, we have many thou- fands of différin: Words, without any alteration at all, in the Letters themfelves ; ana might have ten timesas many more. In like manner, therefore, or in the felf fame analogous way, as the Letters of the AL phabet, are the Principles of Words , fo Principles, are the Alphabet of Lhings. 11. §. What wehavefaid of Principles ; and of Mixture as confe- quent thereupon; may be a foundation for an intelligible account, of the Nature and Caufe of moft of the Iatrinfick Properties,and Qualities of Bodies: asof Gravity, Levity, Fixity, Fluidity, Angularity, Roundnefs, Heat, Cold, Blacknefs, Whitenefs, Sowernefs, Sweetnes, Fragranoy, Petidnefi, and very many more. I fay an intelligible account 3 fc. fuch as is grounded upon the Notions of Senfe, and made out Me- chanically. 329 for this, or any one Ledfure, 1 fhall, before I come to the Caufes of Mixture, only deduce from the Preifes , thefe following Corollaries. 12. §. Firft, That there is no alteration of Principles or of Ele- one, wereas five to tex, of a fecond, as five to fifteen; ofa third, as five to twenty, &e. Orifthat of one, be as fiveto fix; ofa fecond, as fix to fevens ofathird, as feven to eight. By which, and byother I The Nature of Mixture, But the exemplifieation hercof, being too large a field for The ground of which conceit, is that; of three being but four Elements, and all in every particle of the mixed Body. And fo men being puzeled, how from thence to make out the infinite variety of Bodies, they feigned them to be alterable, and altered, upon every perfect Mixture. Not confidering, that if their four Elements be alterable ; as few as they are, no fewer then three of them maybe {pared : for one Element,if alterable, may belmade any. 13. §, Hence, Secondly, may be folved that great Di/pute, Whe- ther fuch as we call Lixivzal Salts, are made by the free Forfirff, No Principle is made by the fire: all Principles being unalterable s and therefore unmakable. Secondly, We muft therefore diftinguifh Ch. 2. $. 3. betwixt the Principle, and its various Mixture with other Principles from whence it may receive different Shapes and Names. Wherefore, a Lixivial Salt, qua Lixivial, is certainly ade by the fire. But gua tenus Salt, itis not: that Principle being extratfable out of mot Bodies; and by divers other mays, then by the fire. For whether you Caleine a body, orelfe Ferment it, (after the manner fhewed by the curious Improver of Chimical Knowledg, Dr. Daniel cox) or putrifie it under ground, or drown it in the Sea; it {till yieldeth fome kind of Sait. All which Salts are made, not by making the Saline Principle ; but only byits being differently asixed, by thof feveral ways ofthe Solution of Bodies) with other Principles : from which its different Mixture, it receives the various Denominations; of Marine, Nix trous, Volatile, or Lixivial. 14. §. Hence, Thirdly, the moft perfeE Mixture of Bodies, can gono higher than Coxtaé#. For all Principles are unalterable 5 and all Ch. 4. Matter is impenetrable 5 as hath been faid. In the molt vifible and laxe Ch. 3. $3 §.2 Mixture, there is Contad 5 and inthe molt Jubtile and perfec, as in Generation it felf, there is xothing more. 15. $. Hence, Fourthly, we eafily underftand, howdivers of the fame Principles, belonging both to Vegetables and many. other Bodies, are alfo atfually exiftent in the Body of Man. Becaufe even in Gene- ration or Tranfimutation, the Principles which are tranflated from one Body to another, as from a Vegetable to an Avimal, are not in the leaft alter'd in themfelves; but only their Mixture, that is, their Conjugation, Proportion and Location, is varied. 16. §. Hencealfo thedifference of mixture, arifing from the difference of Contaét, is intelligible ; /e. as to thofe three degrees, Congres &ation, Union, and Concentration, Congregation, and Inconfiftent Mixture, is when the feveral Atomes touch but in a Poimt, or fmaller part. In which manner, I have divers Ch.3. $2 8s atguments, inducing me to believe the Atomes ofall Fluid Bodies, gua Fluid, do touch 5 and in xo other. Mm 2 Waion |
