thereof; the Frit afterwards growing tofome head, and fo inter-

and therefrom fuperícdes the fervice of the faid Braz to it flf 
fifteen for its Parenchyma, and five for its Seed. The Coar is origina 
ted from the Pith; for the sap finding room enough in the Parenchyora, 
through which to difpence it felf all abroad, quits the Pith, which 
eby hardens into a Coar. Thus we fee the Infertions, although 
iginate from the Cortical Body, yet their Parts being, by the Ixof- 
culations of the Lignous, fo much comprefs'd and made to co-incide 
together, they become a Body very compact and denfe. And in the 
Barque the fame thing is effe&ted by Arefallion only, ora meer vaydance 
ofthe Sap ; the Inner Part whereof,though foft and fappy, yet its fuper- 
ficial Rind is often fo hard and fmooth, that it may be fairly writ up- 
on. The Parts of an Apple, See in the Figures belonging to the Third

ES They are many of them difperfed throughout the whole Parenchyma:

Je of the Pear, furround the Acetary there, in a fomewhat Globular Form, 
About the stalk they ftand more diftant; but towards the Cork or 
Stool of the Flower, they {till grow clofer, and there at laft gather

the Acetary; 'is allways four, and by the bounding of the Calculary 
of a Globular Figure. “Tis a fimple Body, having neither any of the 
Lignous branched in it, nor any Calculous Knots. It is of the fame füb- 
ftantial nature with the outer Parenchyma; but whether it be abfo- 
lutely one withit, or bederived immediately from the Pith, my En- 
quiries yet made, determine not. 
4. $. The Original of the Calculary Ifeem to have neglected. But 
hereof we may here belt fay, that whereas all the other Parts are Ef 
Sential and truly Vital; the Calewlary is not: but that the feveral Kwots 
whereof it confifts, are only lo many meer Concretions or Precipitations 
out ofthe Sap; as in Urines, Wines, and other Liquors, we often 
fee. And that the Precipitation is made by the mixture and re-aétion 
of the Tindures of the Lignous and Cortical Bodies upon each other: 
Even as all Vegetable Nutrition or Fixation of Parts is alfo made by the 
joynt efficiency of the two fame Timéfures, as hath been faid. Hence 
we find, that as the Acetary hath no Branehes of the Lignous Body, fo 
ueither hath it any Kuots, Hence likewife it is, that we have fo dif- 
ferent and contrary a taft in the Parenchyma beyond the Calewlary, from 
that in the Acetary : For whereas this is four, that, wherein the faid 
Precipitations are made, is {weet 5 being much alike effect to what we 
find in mixing of Corals, &ex with Vinegar or other acid Liquors. The
