Show “The Power of Mixture. Led. L Let.= The Power and Ofe of Mixture. “neither the Nitre with the Oy/, nor the Oy/ with the Spirit, nor the Nitre with theSpirit,will make theleat Ebullition: yetall three mingled tocether, make avery confpicuows one. The Spirit of Wine being as the Sulphur 5 andfo that, and the Nétre together,{tanding,as it were, in the ftead of an Arkalizate, that is, a Sulphurious Salt, againft the Oy! of Vitriol. Diversother Experiments maybe fhew'n of the like Nature. 7. §. In thelatt place, for the Imitation of a Minera! Body, 1 will inftance in two, fc. Nitre and Marine Salt; if |may have leave to reckon them among(t Mineral Bodies. As for Nitre, by mixing offour Liquors together, and then fetting them to fhoot ; I have obtained Chry- flals oftrue and perfec salt; which have had much of a witrows taft 5 and would be melted with a gentle Heat, as Nitre is; and evenas ealily as Butyr it felf: 1 mean not, by the addition of any fort of Liquor, or anyother Body, todiffolve it; but only bythe fire. 8. §. AndasforaSea-Salt, that I might Lmitate Nature for the mahing thereof, I confiderd, That the faid Sat is nothing elfe but that of Avimals and Vegetables, freed from its true Spirit and suJ- phur, andfome Saline particles, fpecifically Animal or Vegetable, together withthem. For both Avimal and Vegetable Bodies being continually carried byall Revers into the Sea 5 and many likewife by shipwrack and divers other waysimmerfed therein: they are at latt corrupted, that is, their Compounding parts are opened and refolved. Yet the Refolution being in the Water, is not made precipitately , as it isin the Air 5 but by degrees, and very gevtly; whence the Sulphurious and other Volatile parts, in their Avolation, make not fo muchhaffe, as to carry themore fixed Saline parts along with them 5 but leaveth them be- hind in the Water, which izsbibeth them astheir proper Menfirunm. And the Imitation of Nature herein, may be performed thus; Put asmuch of aLixivial Salt as you pleafe, into a wide-mouth’d Bottle, and with fair Water makea {trong Solution of it 5 fo as {ome part thereof may remain uzrefolved at the bottom of the Bottle. Let the Bottle ftand thus for the {pace of abouthalf or three quarters of a year, all the time unftopped. In which time, many of the Sw/phurzous and other Volatile parts gradually flying away 5 the top of the wxrefolued Salt will be incruffate, or as it were frofted over, with many {mall and hard Cowcretions, which, in their nature, are become a true Sea-Szlt. Whereof there is a double Proof; Firff, In that moft of the faid Con- INSTANCEIII, & IV. ROM theaforefaid Premiffes, and by the aforefaid Means, thereig no doubt to be made, but that alfo the other /enfible Qualities of Bodies may be Iwitated, as their Odors, and Ta/ts. And that not only the general ones, as Fragrant, or Aftringent: but alfo thofe which are Jpecifical and proper to fuch afpecies of Bodies. 2. §. Thus for Example, by mixing Spirit of Nitre or Vitriol with retfified Oyl of Turpentine, and fome other Vegetable Oyls, feverally, and ina due Proportion and Time, 1 have Imitated the Smells of divers Vegetables 5 as of Tanfy, of Lignum Rhodium, and others. And I conclude it feafable, To Imitate the Taft or Smell of Musk, or Amber- greece, or axy otherbody in the world. 3. §. Hence alfo we may be Taught, How to Imitate the Faculties, as well as other Qualities of Bodies. The reafon is, becaufe even thefe have no dependance upon any fbifantiel Form: but are the meerrefult of Mixture; effeGted by the fame Caufes, whether in Nature or Art; asIthink I have made to appear in the foregoing Idea. And Id. §. 55. as in the Premijfes of this Di/courfe hath been fhew'd. Ch.2.$.10: Ch.3.$.10: INSTANCE V: ROM whence, agaiz,it is likewifea Key to Di/cover the Nature of Bodies, For how far foever we can attain to Mizgle, orto Make them, we may alfo know whatthey are. 2. §. For Bodies are mingleable, either of them/élues, or by fome Third. As to thofe which wingle ofthemfélves, we may certainly conclude, That there is a congruity betwixt them, in fome refpect or other: $o uponvarious Tryals I find, That E/fential Oyls do more eafily im bibe an Acid, then an Alkaly. Whence it is evident, That there is fome Congruity and Similitude betwixt Effentian oyls, and an Acid, which there isnot betwixt the faid Oyls and an Alkaly. 3. §. Astothofe that mingle only by fome third; we may alfocertainly conclude, That though the two extreams are unlike; yet that they have both of them fome congruity with that third, by which they cretions are of aCubical, or verylike Figure. Efpecially on their upper parts; becaufe having a fixed Body for their Bafis, their under parts, are united. therefore, contiguousthereto, are lefs regular. Degree of Mixture. Thusthe Acid Spirit of Nitre, asis faid, will coagulate Oyl-Olive, and render it confiftent. Whence it might be thought, That any other {trong Acid will do the like; and that therefore, there is no great difference in the Nature of the faid Acid Liquors. But the contrary hereunto, is proved by Experiment. For having digefted the Whereas the parts of the Salt inthe Sea, being environedonall fides with a Fluid; their Figure is onall fides regular. Secondly, In that a {trong Acid Spirit or Oyl being poured upon a full bodyd Solution hereof; yet it maketh herewith no Ebullition » which is alfo the property of Sea-Salt. And thus much for the more General Ivitation of Bodies. 4. $. Moreover, We may make a Judgment from the manner of fame Oy! in the fame warner, and for amuchlonger time, with ftrong Oyl of Sulphur; althoughit thenceacquired fome change of Colour, yet not any Confi/tence. 5. §. Again, Becaufe the faid Spirit of Nitre coagulates Oyl-Olive 3 itmight be expected, it fhould havethe fame effet upon Oyl of Ani= feeds; or, atleaft, that if other Acids will Coagulate Oyl of Anifeeds; that this fhould doit bef. But Experiment proveth thecontrary. For of all I have tryed, Oy! of Vitriolis the only Acid that doth it inftans taneoufly. Oyl of Sulphur, if very trong, will do it; but not fo Joon, Na 2 nor |
