ASTLY, and confequently, It isa Key To Difcover the Medicinal Use and Operation of Bodies. Thus, for Example, by the Imita- ie EY G, : thefirft Edition ofthefore:going Dit Ch. 5. Lnft. courle, made mention of the preparation o. are, and whem, and wherefore tobe ued. For what are Maftick, Fran- kincenfe,Olibanum, Benzoin, and otherlike Rofins, or Refinous Gums, for their principle and predominant parts, thatis, qua Rofins 5 but Bodies refulting from Natural, in like manner, as have fhewed, they may be made to refult, from Artificial Mixture? Thatis to fay, the Olcows, and Acid parts of Vegetables, being both affufed and mingled together, per minima, wfome one fort of Feffels in a Plant, they thus éacorporate into one confiftent and friable Body, which wecall Rofiz. >. §. Nowfrom hence it is, That the faid Rofizs, and Refinous Gums as alfo Amber and Sulphur for the fame Reafons5 are of fo great and effectual Uje againft moft thix and falt Rhewms 5 fe. as they are Acidoleows Bodies. For by their Acid parts, whichin all thefe Bodies areexceeding copious, they mortifieand refratt thofe Salt ones, which feed the Rhenm. Andby their oleows parts, the fame Salt ones are al- fo Imbibed. Whence, they areall, in fome degree,incorporated together 5 that is, The Rheum is thickzed: whichis the defired effe#. . §. Whereas, onthe contrary, if the Cough proceed not from a thin, and {pecially a Salt Rheum, but from a Vifcous Flegm3 the ule of many other Bodies which are alfo moreoleous, and abound notfo much with an Acid as thefe do, efpefcially fome of thers, is more proper: fach asthe/e, in this Cafe, proving fometimes not onlyineffectual, but prejudicial. Since the very Caufe of the faid Vifcoufne/s of Phlegm, is chiefly fome great Acidity in the Blood, or in fome other part, as may be proved bydivers Arguments. 4. §. Manymore Instances might be hereunto fubjoyned : and may hereafter be offered to the acceptance of fuch, whoare inquifitive into matters of this Nature. If Ifhall not herein anticipate, or reiterate the Thoughts and Obfervations, of thofe two Accurate and Learwed Perfons Dr. Willis, and Dr. Walter Needham, as to what the one hath already publifhed, and both have put usin Expeéfation of. But the Inftances alreadygiven, are fufficient to evidence what I have faid. And, I hope, this prefent Di/courfe to prove, infome meafure, thus much 5 ThatBxperiment, and the Common Notions of Senfé are prolifick; and that nothing is Barrez, but Phanfieand Imagination. a i. §.8. tial Oyls, fo as to become olGty caustic any anoyly Liquor. fall here acquaint the Reader, 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 dion of Reins and Refinous Gums, we certainly know whatall of them the Meridiag-Sun in Summer, continued for the fpace*of three Weeks oraMonth; and inthe mean time, to be now and then ftirred a little together. The Yelk will by degrees, imbibe the Oy!, and at length be: incorporated with it, and become a Balfam, as white as milk, eafily diffoluble in any watery or winy Liquor. <7 2..§. Iconfefs, that it will be very difficult to prepare any good quantity for ufe, this way. But this being a fafficient proof of the poflibility of fuch a méxture; I confidered, whether the application of fome other forementioned Caufe of Mixture, might not fupply the defect of this: and hereupon, have made feveral fuccefsful tryals ; not only for the mixing of the faid Oyls, but likewife of all forts of Rofins and Gums with any wizy or watery Liquor, in great quantities, in a fhort time, and without much trouble. But for the mixing offome of them, the Ye/k of an Egg alone will not ferve, without intervening of fome other fociable Body, according togaia one ofeaoh the Rules given Cf, 5. Laff: in the foregoing Di/cour/e. 3. §. In the fame Difcourfe, upon certain premifes, I have laid a §.6. downthis following conclufion. —— By accumulating the Canfes of Mixture, that is, by joyning Ch, 5. 38 “two or three or more together 5 or by applying more in fome cafes “ where Natu¥e applyeth fewer 3 we may be able to make,if not a more “perfect, 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 meanscontrived for the purpofe, for “the fpace of a Week or Month,or longer without Ceffation. Which “may probably produce, not only ftrange, but ufeful effects, in the “SOL “ I i of a and the mixture of other Bodies. 4. §. For the proof whereof, and that I had through i what I have faid; Mr. Pappiz hath fince given us an eon ee, in his new Digefter. Whichis,a Balneum Marie clanure: all Infufions and Digeftions made with Donble Vefels, having hitherto been made with the outer Vefél, open. Sothat whereas by the old way of Digeftion, their is no.other Power made ufe of but that of Heat: iti thi way, that alfo of Compreffion is joyned therewith: ra |
