Show ThePower of Mixture. Week, or Month, or longer, without ceflation. Led. I. roduce, not only /fravge, but wfeful Effeds, in the Solution of fome, and the Mixture of other Bodies. And mayferve to mix fuch Bodies, asthroughthe fmal/ number oftheir congruous parts, are hardly mingleable any other wav. itation being, as carrying the Key to and fro, till it hit the Lock; or within the Lock , till it hit the Wards. 5. $- Secondly, For the Choice of materials, if they are not im- mediately, that is, of themfelves, mingleable, we are then to turn one by mediation g. Species of Mixture intoa Rule, which is, To mix them offome third, whether more fimple or compounded Body, which may be congruous iv part to them both: as Sulphurous Salts are to Water and Oyls and are forthat reafon mingieable with either ofthem. Or, By any to congruous Bodies, which are alfo, i# part, congruous to tive others: and otherlike ways. Led. I. 233 The Power of Mixture. Which may probably Whereby the parts of Bodies, though never {0 heterogeneows, may yet be all bouvd and locKd up together. Even as twenty Keys may be united, only by uxiting the two Rings whereonthey hang. 6. §. The Confideration of thefe things, have put me upon making feveral Experiments, for the minghng of heterogeneous Bodics, I fhall give two Examples of Tryal ; the one upon Flaid, the otherupon confiftent Bodies. 7. §. For the firf?, Ltook Oy! of Avifceds, and pouring it upon another Body3 I fo order’d it, that it was thereby turned into a per- fect milk-rhite Balfam, or Butyr. By which means the faid Oy! became mingleable with any Winy, or Watery Liquors eafily, and infiantaneoufly difolving therein, im the form of a milk, And xote, That thisis done, without the leaf? alteration of the Smell, Taft, Nature, or Operation of the faid Qyl. By fomewhat the like means, not only Ost of Axiféeds, but anyother ftillatitions Oyl, may be transformed Bag. Firft, For the Iwitation of an Animal Body, I will inftance in Fat. Which may be wade thus; Take Oy/ Olive, and pour it upon high Spirit of Nitre. Then digeft them forfome days. By degrees, the Oy! becomesof the colour of Marrow; andat Jatt, is congealed, or hardned into a white Fat or Butter, which diffolveth only bythe fire, as that of Avimals. In converting Oy! thus into Fut, it is to be xoted, That it hardens moft upon the exhalation of fome of the more Sulphureows parts of the Spirit of Nitre. Which I effeéted, well enough for my purpofe, by unftopping theglafs after fome time of dige/tion 5 and fo fuffering the Oy! to diffolue and thickendivers times byfucceflive heat and cold Hence, The true Congealing Principle, isa Spirit of Nitre feparated from its Sulphur. For the better doing whereof, the Aer isa moft commodious Menftruum to the faid Spirit of Nitre. Whencealfo, if we could procure fuch a Spirit of Nitre, we might congeal Water in the midft of Summer. We might alfo refrigerate Rooms herewith Artificially, Andmight Imitate all frofty Meteors. For the making of Fat, is but the Durable Congelation of Oyl: which may be done without fros?, as I have fhewed how. Hencealfo it appears, That Avimal Fatit felf, is but the Curdling of the Oyly parts of the Blood; either by fome of its ownSaline parts 5 or by the Nitrous parts of the Aer mingled therewith. Hence likewife it is, That fome Animals, as Conies, and Fieldfares, grow fatter in frofty weather: the oily parts of the blood, being then more than ordinarily coagulated with a greater abundance ofwitrous parts received from the Aer into their bodies. For the fame reafon it is, That the Fat of Land-Avimals is hard 3 whereas that of Fifbes is very foft, and runs all to Oyl, /2. Becaufe be render’deafily diffoluble in Water 5 as may Rofiz, and all refinoys the Water, wherein they live, and which they have inftead of breath, hath but very few vziétrous parts in it, in comparifon of what the Aer hath. 4. §. Secondly, For the Imitation of a Vegetable Body, 1 will give three Inftances ; In Rofiz, Gum, and a Lixivial Salt. The firfé may be made thus; Take good Oy! of Vitriol, and dropit upon Oyl of Axifefeeds 5 and they will forthwith zzcorporate together 5 andby degrees, will harden into a perfect Rofiz, with the geveral and defining Properties and friable Gums. As alfo Wax : and this without changing much of their Color, Taff, or Smell. Whereof likewile, whatfoever others at leaft, not any more, then anynatural Rofiz or Gum: yet very eafily into a milk-white Butyr 3 Water or any other Liquor. and in like manner be mingled with Which is of variows uje in Medicine; and what I find oftentimes very convenient and advantageous to be done. 8. §. Again, not only Fluid but confi/fent Bodies, which of themfelves will mix only with Oyl; by due mzxtwre with other Bodies, may may do, the Phyjician may make a manifold Uye. INSTANCE YY Mixture alfo, we may be taught to Imitate the Produdions of it. But I will alfo give an Instance of fomewhat that maybe done ia And, by fire: as alfo higly iwflamable: and exceeding friable, Althoughthis Artificial Rofiz, be the refult of two Liquors, both which very ftrongly affect the Senfé: yet being well wafhed from the uxincorporated parts, II. } Nature. As to which, from what we have before {aid of Mixture, we may conclude; That there is no Generation of Bodies unorganical, but whatis in the Power of Mixtureto imitate. As of Animals, to Imitate Blood, Fat, Chyle, Spittle, Flegm, pile, &c. OF Vegetables, tolmitate a Milk, atucilage, Rofin, Gum, or Salt. Of Minerals, to ImitateVitriol, A#om, and other Salts; as alfo Metals, and the like. 2. §. Ido not fay,J? I cando allthis: yet if? upon good Premifes, i > we can conclude this poffible to be done ; it is one {tep to the doing of every kind. of a truly Natural Refinous Gum. Being not at all diffoluble in Water 5 or ae 32 8- (whichis to be done with fome care ) it hath fcarce any Taft or Smell, The Concentration of thefe two Liquors, is likewife fo wniver/al 5 that the Rofiz is not made by Precipitation, but almoft a total Combination of the faid Liquors; and that with fcarce fo much, as any w/b/e fumes. 5. §. Again, Having taken a certain Powder and a Saline Liquor, and mixed them together in a bottle, and fo digefied them for fome time ; the Pomder wasat lat tranfmnutedto a perfect Oily Gum 3 which will alfo défolve either in Oylor in Water 3 inthe felf fame manner, as Galbanum, Ammoniac, and the like will do. 6. §. And Lajftly, A Lixivial Salt may be imitated thus; Take Nitre, Oyl of Vitriol, and high spirit of Wine, of each alike quantity, Of thefe three Bodies, not any two being put together, that 1s to fay Na neither, |
