‘Led. 1. The Power and Ofe of Mixture, 237 
Oe ee 

An Appendix to the precedent difcourfe of 
Mixture, 
A VING, in the firlt Edition of the foregoing Dif- Ch. 5. Ixft, 
courfe, made mention of the preparation of Effen- 1, §.8: 
tial Oyls, {0 4s to become eafily mingleable with 
any azoyly Liquor. 1 fhall 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, witha very foft heat, like that of 
i the Meridiae Sun in Summer, continued for the 
fpace’of three Weeks or aMonths and inthe mean time, to be now 
and then ftirred alittle together. The Yelk will by degrees, imbibe the 
Oy, and at length be incorporated with it, and become a Balam, as 
white as Milk, eafily diffoluble in any watery or winy Liquor. 
2. .§. Iconfefs, that it will be very difficult to prepare any good 
quantity for ufe, this way. But this being a fufficient proof of the 
poffibility of fuch 4 mzxtvre5 I confidered, whether the application of 
fome other forementioned Cau/é of Mixture, might not fupply the de 
fe& ofthis: and hereupon, have made feveral fuccefsful tryals 5 not 
only for the mixing of the faid Oyls, but likewife of all forts.of Rofins 
and Gums with any winy or watery Liquor, in great quantities, in a 
fhort time, and without much trouble. But for the mixing of fome of 
them, the I¢/k of an. Egg alone will not ferve; without the interve- 
ning of fome other fociable Body; according to one of the Rules given CA, &. Tuft: 
in the foregoing Di/courfe. . itn Cole 
3. §. In the fame Difcourfe, upon certain premifes, I have laid 
down this following conclufion. Che 6: 5. 84 
——. By accumulating the Caufés of Mixture, that is, by joyning ~~ 3 Ped! 
“two or three or more together 5 or by applying more in fome cafes, 
“ where Nature applyeth fewer 3 we may be able to make,if not a more 
“perfect, yet a far more fpeedy Mixtire,than Nature doth. As by joyn- 
«ing COMPRESSION, Heat, and violent Agitation,and fo con- 
“ tinuing them altogether,by fome mieans contrived for the purpofe; for 
“the {pace of a Week or Month,or longer without Ceffation. Which 
“may probably produce, not only ftrange, but ufeful effects, in the 
“SOLUTION of fome, and the mixture of other Bodies. 
4. g. For the proof whereof, and that I had throughly weighed 
what I have faid; Mr. Pappiz hath fince given us an ingenious Inftance; 
in his hew Digeffer. Which is,a Balneus: Marie claw{um : all Infufions 
and Digeftions iade with Double Vefels, having hitherto been made 
with the outer Vefel; open. So that whereas by the old way of Di- 
geftion, their is no other Power made ufe of but that of Heat: itt this 
ways that alfo of Compreffion is joyned therewith:
