An Appendix to the precedent difcomfe of 
Mixture, 
A VING, in the firft Edition of the foregoing Dit 
courfe, made mention of the preparation of Effen- 
tial Oyls, fo as to become eafily mingleable with 
any wmoyly Liquor: Y (hall here acquaint the Rea- 
der, That this may be done, by digefting any of 
the faid Oyls with about an equal quantity of the 
Yelk of an Egg, with a very foft beat, like that of 
the Meridian Sun in Summer, continued for the 
fpace of three’Weeks or a Month; and inthe mean! time, to be now 
and then ftirred a little together. The Yelk will by degrees, imbibe the 
Oyl, and at length be incorporated with it, and) become a Balfam, as 
white as Milk, eafily diffoluble in any watery or wizy Liquor. 
2. §. Iconfeß, thatit will be very difficult to prepate any good 
quantity for ufe, this way. But this being a fufficient proof of the 
pofübility of fuch a Mixtures I confidered, whether the application of 
fome other forementioned Canfe of Mixture, might not fupply the de- 
fect of this: and hereupon, have made feveral fuccefiful tryals ; not 
only for the mixing of the faid Oyls, but likewife o£ all forts of Rofins 
and Gums with any winy or watery Liquor, in) greatóquantities, in a 
fhort time, and without much trouble. But for the mixing of fome of 
them, the Yelk of an Egg alone will not ferve, without the interve- 
ning of fome other fociable Body, according to one of the Rules given 
in the foregoing Difconrfe. 
3. $. In the fame Difcourfe, upon certain premifes, I have laid 
down this following conclufion. 
—— By accumulating the Caufés of Mixture, that is, by joyning 
“two or three or more together 5 or by applying more in fome cafes, 
< where Nature applyeth fewer 53 we may be able to make,if not a more 
“perfed, yet a far more fpeedy Mixture,than Nature doth. As by joyn- 
“ing COMPRESSION, Heat, and violent Agitation, and fo con- 
“ tinuing them altogether,by fome means contrived for the purpofe, for 
“the {pace of a Week or Month,or longer without Cefatior. Which 
“may probably produce, not only ftrange, but ufeful effects, in the 
“SOLUTION of fome, and the mixture of other Bodies. 
4. $. For the proof whereof, and that I had throughly weighed 
what I have (aid, Mr. Pappin hath fince given us an ingenious Inftance, 
inhis new Digeffer. Which is, a Balneum Marie clanfum + all Infufions 
and Digeftions made with Double Vefels, having hitherto been made 
with the outer Vefél, open. So that whereas by the old way of Di- 
geftion, their is no other Power made ufe of but that of Heat: in this 
ways that alfo of Compreffion is joyned therewith:
