Show Let.L ~- The Power of Mixture, The Canfes of Mixture. 5. §. Le&I. CAMA Pave Digeffion. For whichthere isthe fame reafon, as for Mixture, by Solution. For, Firft, All heat doth attezuate, that is, ftill further feparate the parts of a Body; and forender them more mingleable with ‘the parts of azother. Of the POWE RandUSE of Mixture. And therefore, Secondly , Doth alfo add more Motion to them, in order to their Mixture. 6. §. Agitation. Which] aminducedtobelieve a great and effectual means of Mixture, upon divers Confiderations. As, Firft, That the gy VING enumerated the general Canfés, we thall, @, \altly, enquire into the Power and Ufe of Mixture5 ZB or, into whatit canDo and Teach. And 1 thall In- making of Blood in the Bodies of Animals, and the mixing ofthe Chyle therewith, is very much promoted by the fame means ; fc. by the Agi- tation of the parts of the Blood and Chyle, in their continual Circulation, Again, from the waking of Butter out of Milk, by the fame means: wherebyaloneis madea/éparation of the oleous parts from the Whey, and Conjunttion of the Oleows together. Moreover, From the great Effe#s of Digeftion ; well knownto all that are converfant in Chymical Preparations. Which Digeftionit felf, isbuta kind of infenfible agitation ofthe parts of digefted Bodies. “Tis alfo a known Experiment , That the readieft wayto diflolve Sugar in Wine or other Liquor 5 is to give the Veffel a hafty turn, together with a fiart knock, againft any hard and fteady Body: wherebyall the parts of the Sugar and Liquor, are put into a vehement Agitation, and fo the Sugar immediately diffolved, and mixed with the Liquor. And remember, that having (with intent, tomake Mr, Matthews’s Pill) put fome Oyl of Turpentine and Salt of Tartar together in a Bottle, and fent it up hither out of the Country 1 found, that the continual Agitation upon the Road, forthree or four days, haddone more towards their Mixture; than far greater time of Digeftion alone had donebefore. Andit is certain, That avehement Agitation, efpecially, if continu’d, or joyned with Dige- ftion, willaccelerate the Mixture of fome Bodies, ten timesmore, than any bare Digeftion alone 5 as may be proved by many Experiments. I will inftance in this one. Let fome Oy! of Turpentine and good Spirit of Nétre be ftop’d up together in a Bottle, and the Bottle held to the Fire, ull the Liquors bea little heated, and begin to bubble. Then having removed it, and the Bubbles by degrees increafing more and mores thetwo Liquors will of themfelves, at laft fall into fo impe- tuous an Ebullition,as to make a kind ofExplofions fendingforth afnsoak for the {pace of almoft two yards high. Whereupon, the parts of both the Liquors, being violently agitated, they are, in a great portion, incorporated into a thick Balfarein a moment: and that without any intenfe heat, as maybe felt by the Bottle. And thus much for the Canfes of Mixture. % {tancein fix particulars. Féri?, to Renderall Bodies 2 Sociable, whatfoever they be. Secondly, To Make Artificial Bodiesin Imitation ofthofe of Naturesown A production. Thirdly, to makeor imitate the fenjible Qualities of Bodies 5 as Smells, and Tajts. Fourthly, To make, or imitatetheir Faculties. Fifthh, risa Key, to difcover the Nature of Bodies. Sixthly, To difcover their Ufe, and the Manner of their Medicinal Operation. INSTANCE IL IR ST, To renderall Bodies Sociable or Mingleable: as Water with Oyl, Salt with Spirit, and the like. For Natural and Arti- 7 ficial Mixture, are the fame 5 as we have before proved, If therefore Nature can do it, as we fee in the Generation of Bodies fhe doth, ‘tis ikewife i Power of Art to doit. ee nk for the doing of it, two general Rules refult from the Premiffes, fc. The Application of Canfes, and the Choice of Materials. As for the Can/és, they are fuch as] have now inftane’din. And for CA. 4. the Application of them, I thall give thefe two Rules. 3. §. Firft, That we tread in Natures fteps as near as we can a ane only in the Application of fuch a Canfe, as may bemoft proper forfucha Mixtures but al(o in allowingitfifficient time forits effet. For fowefee Nature her (elf, for her more perfec Mixtures, ufaally doth. She maketh not a Flower, or an Apple, a Horfe, or a Man, ina moment5 butallthings by degreess and for her more perfect and elaborate a ives, for the moft part, fhe requireth more time. Becaufé all fuch Mixtures are made and carri’d on per minima; and therefore require a greater time for the compleating of them. 4. §. I ene A fecoud Rule is, Not only to make a due Application of the Cavfes; but fometimes to Accummlate them. By which means, we may not only, imitate Nature, but in fome cafes go beyond her. For as by adding a Graft or Budtothe Stock, wemay produce Fruitfooner, and fometimesbetter, than Nature by the Stock alone would do: So here, by accumulating the Canjés of Mixture,thatis, by joyning ee, three, or more together; or by applying more in fome Cafes, where J be ture applyeth fewer; we may be able to make, if npr a more perfect, yetafar more fpeedy Mixture, than Nature doth. As by joyning Cov- preffion, Heat, andviolent Agitation, and fo continuing them all together, by fome means contrived for the purpofe, for the ipace |
