Week, or Month, or longer, without ceffation. Which may probably 
produce, not only ffrange, but ufeful Effects, in the Solution of fome, 
and the Mixture of other Bodies. And may ferve to ~#x fuch Bodies, 
asthrough the fizall number of theit congriows parts, are hardly mingle- - 
able any other way. Agitation being, as carrying the Key to and 
fro, till it hitthe 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, ~ingleable; we are then to turn one 
Species of Micture into a Rule; which is, To mix them by mediation 
of fome third, whether more fimple or compounded Body, which may 
be congfuons 7# part to them both: as Sulphurous Salts are to Water and 
Oyl5 and are for that reafon mingieable with either ofthem. Or, By 
any tio congruous Bodies, which are alfo, 7 part, congruous to two 
others: and other like ways. Whereby the parts of Bodies, though 
never fo heterogeneous, may yet be all bound and lockd up together. 
Even as twenty Keys may be united, only by uniting the two Rings 
whereon they hang. 
6. §. The Confideration of thefe things, have put me upon ma- 
king feveral Experiments, for the mingling of heterogeneous Bodies. I 
fhall give two Examples of Tryal ; the one upon Fiid, the otherup- 
on confiftent Bodies. 
7. §. For the firfz, I took Oy! of Avifeeds, and pouring it upon a- 
nother Body 5 I fo order‘d it, that it was thereby turned into a per- 
fect. milk-white Balfam, or Butyr. By which means the faid Oy] be- 
came mingleable with any Winy, or Watery Liquors eafily, and inftanta- 
neoufly diffoloing therein, in the form of a wk, And xote, That 
this is done, without the /eaft alteration of the Smell, Taff, Nature, or 
Operation of the faid Oyl. By fomewhat the like means, not only 
Oy! of Anifeeds, but any other /p#latitious Oyl, may be transformed 
into a wilk-white Butyr 5 and in like manner be mingled with 
‘Water or any other Liquor. Which is of varios ufe in Medicine 5 and 
what I find oftentimes very convenient and advantageous to be 
done. 
8. §. Again, not only Flxid but confiffent Bodies, which of them- 
felves will mix only with Osl; by due mzxture with other Bodies, may 
be render'd eafily diffoluble in Water 5 as may Rofz, and all refinous 
and friable Gums. As alfo Wax : and this without changing much 
of their Color, Taft, or Smell... Whereof likewife, whatfoever others 
may do, the Phyficdan may make a manifold Ue. 
INSTANCE IL 
Y Mixture alfo, we may be taught to Imitate the Produdions of 
| Nature. As to which, from what we have before {aid of Mix- 
ture, we may conclude; That there is no Geueraticn of Bodies xnor- 
ganical, but whatis in the Power of Mixtureto imitate. As of Animals, 
to Imitate Blood, Fat, Chyle, Spittle, Flegm, Bile, &c. Of Vegetables, 
to[mitate a Milk, Mucilage, Rofin, Gum, or Salt. Of Mineral;, to 
ImitateVitriol, Allow, and other Salts 5 as alfo Metals, and the like. 
2. §. Ido not fay, I cando allthis: yet if, upon good Premifts, 
we can conclude this poffible to be done 5 it is one ftep to the doing of 
it. But I will alfo give an Instance of fomewhat that may be doxe in 
every.kind. And, : BRS a
