thereof; the Fruit afterwards growing to fome head, and {o inter- 
cepting and preying upon the Aliment of the Flower, ftarves that 
and therefrom fuperfedes the fervice of the faid Branches to it felf, 
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 Parenchyma, 
through which to difpence it felf all abroad, quits the Pith, which 
thereby hardens into a Coar. Thus we fee the Infértions, although 
originate from the Cortical Body, yet their Parts being, by the Izof- 
culations of the Lignous, fo much comprefsid and made to co-incide 
together, they become a Body very compact and denfe. And in the 
Barque the fame thing is effected by Arefatfion only, ora meer voydance 
_ofthe Sap 3 the Iver 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 
JPart of the Fourth Book, 
3. §. IN A PEAR thereare five diftintt Parts, the Piling, the 
Parenchyma, Branchery, Calculary, and Acetary, The three former are 
here and in an Apple much alike ; faving that here the Juwer or Seed- 
Branches ordinarily ftand double. The Caleulary ( moft obfervable 
in rough-tafted, or Choak-Pears ) isa Congeries of little ftony Kvots. 
They are many of them difperfed throughout the whole Parenchyma: 
But lying more continuous and compact together towards the Center 
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 ftill grow clofér, and there at laft gather 
(almoft ) into the firmitude ofa Plum-ftone it felf. Within this lies 
the Acefarys ‘tis allways four, and by the bounding of the Calcwlary 
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 fub- 
ftantial nature withthe 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 I feem to have neglected, But 
hereof we may here beft fay, that whereas all the other Parts are Er 
featial and truly Vitals the Calenlary isnot: but that the feveral Kwots 
whereof it confifts, are only fo many meer Coneretions ox Precipitations 
out of the Sap; asein Urines, Wines, and other Liquors, we often 
fee. Andthat the Precipitation is made by the mixture and re-aCtion 
of the Tixdures of the Lignous and Cortical Bodies upon each other: 
Evenas all Vegetable Nutrition or Fixation of Parts is alfo made by the 
joynt efficiency of the two fame Tiniures, as hath been faid. Hence 
we find, that as the Acetary hath no Branches of the Lignous Body, fo 
neither hath it any Kwots. Hence likewife it is, that we have fo dif- 
ferent and contrary a taft in the Parenchymabeyond the Calculary, from 
that inthe Acetary : For whereas thisis four, that, wherein the faid 
Precipitations are made, is {weet 5 being much alike effect to what we 
find in mixing of Corals, &c. with Vinegar or other acid Liquors, The 
Parts ofa Pear, See in Tab. 4. But efpecially in the Figures belonging 
tothe Third Patt of the Fourth Wook.
