Sothe Efeztial Salt of Wormmood, which may be obtained fromthe Lix7vial 5 is Bitter, tranfparent, and commonly, of a Cylindrickfigure: whereas that whichis obtained byCodon, or from the Extra, is tufile(’, greyifh, and almoft Cybick: and that in the Ex- tract of the Green Leaves of Violets, appears in fine tranfparent Shoots, like fo manylittle Needles. And it is probable, That the Sets of moft Kinds of Plants, whether Lixivial or Effential ; and ofthefe,whe- ther obtained by Decoéfion, or otherwife, haveeither their Figure, or other Qualities, proper to themfelves, whereby theyareall diftinguifh- ed one from another. Andlaftly, to make Experiment upon thefe Principles, mixing them with one another, or with other Bodies, or otherwife. 49. §. Iknowit will be difficult to make obfervations ofthis kind uponthe Organical Parts of Plants, feverally. Yet I have thought of fome Ways, wherebytrue and undeceivable ones may be made. And the betterto illuftrate what I mean, I fhall give one or two Inftances of Tryal to this purpofé. For the making of which, and fome others of the like nature, I confidered, That upon the Avatomical Analyfis of allthe Parts of a Plant, I had certainly found, (and fhall hereafter fhew) That in all Plants, there are Two, and only Two Organical Parts Effentially distin, viz. The Pithy Part, and the Lignous Part, ‘or fach others as are analogous to either of Thefe. So that, if we can think ofany Plants, which will affordus either of thefe two,though not per- fetly, yet infome good meafure, fimple and unmixed: We may then fee, by putting themto a Chymical, Teft, what Principles and Propertionof Principles, concur to fpecifie their Subftantial Forms, 50. §. To the Pithy Part, Starch, or pure Manchet is analogous, as having verylittle ofthe Ligwous mixed with them. Itherefore ordered 6 ij ofStarch to be put into a Retort, and witha Receiver affix- ed, to be fetin a Sad Furnace 3 and that all it would yield, fhould, by degrees, be forced over ; which, befides what was evaporated at the Neck ofthe Receiver, was about {6 j. of an acid and eager Liquor, ofa heavyandblackith Oy/z ff, and ofa light Oy! 3 j. The €cput Mortuumcould not be reduced to Afhes, by the ftrongeft heat which a naked fire in that Furnace wouldproduce. : 51. Tothe Lignous part, Hemp or Flaxis analogous, having verylittle ofthe Pithy mixed with them. I caufed therefore ib ij of Flax to be put into.a Retort, and manag’das the Starch : whereupon, it yielded a Liquor, as] remember, fomewhat like the former, and about the fame quantity ; no Oy! which remained liquid, when cold 5 but inftead ofthat a Butyr, almoft of the Confiftence and Colour of the Oyl of Mace ; and ofthis above3 iij, or near fix times the quantity ofthe Oy! which wasyielded by the starch. The Caput Mortunm being burned to a white Af, yielded fome portion of a Lixivial Salt. E $3, $. |
