is it to be prefumed, that they bear a juft Proportion to thof in the 
Trunk of the fame Tree 5 and that therefore they are here larger, thaa 
in an Apple or Pear. The Skiz likewife of a Plum, is more jibrous, 
thick, and tough, than in thofe Frnits. The Ends of thefe Diverfities, 
we fhall prefently fpeak of. } 
2. §. Of the Stone, among{t other particulars wherein the con- 
B.1. Ch.6, trivance of Nature is very admirable, I have formerly fhewed, That

it is compofed of Two or rather Three diftin& Bodies. One of them, 
_the Living 5 which anfwers to the Coar in a Pear. And is originated 
from the Parenchyma, which the Seed-Branch brings along with it, 
through the Chanel in the Side, and at laft into the Hollow, of the 
Stone 3 and is there {pread all over it: as when a {mall Glafs-Pipe, is 
blown and expanded into a Bubble. Or as if a Bladder, being ftretch- 
out, and put throughthe Neck of a Bottle; were then blown up, fo 
as to be every where contiguous to the Sides, and become, as it were, 
the Living of the Boitle. ; 
3. §. The Foundation or Ground of the Outer and more Bulky 
Part of the stone, is the Iner Part of the Parenchyma 5 and anfwers 
to the Acetary in a Pear, As the Fruit grows, the Tartareous Parts 
of the Sap, being continually precipitated upon this Parenchyma, it is 
hereby petrify’d. As will beft be feen, by comparing the feveral A- 
ges of the fame Fruit together. And in fome Stoves; on the Surface 
whereof, fome of the faid Tartareous Parts appear in diftin& Grains. 
So that whereas in a Pear, the Calculary and the Acetary are diftint, 
here in a Plu, they are thrown one into the other. Or, as fome 
Mineral Waters only make a Cruft about a Stick or other Bodies im- 
merféd in them; but others, by finking into thefe Bodies, do here: 
by petrify them: Soina Pear, the Tartareous Parts of the Sap, only 
make a Cruf? about the Acetary; but in a Plum, they fink into the 
Body thereof, or that Part of the Parenchyma, which ftands in the 
place of it, whereby it is converted into a Stone. The F. igures of Stones 
fall hereafter be fpoken of, when I come in the next JPatt, to the Co- 
vers of the Seed. 
4. § AN APRECOCK is of the Phim-Kind. But fome 
things are herein better obferved. As firft, the Pofition of the Blad- 
ders of the Parenchyma. For the Tartareous Parts of the Sap not being 
here difperfed, in little Grains, throughout the Frvit, asin a Pear 3 
but all thrown off into the Stoze: the Bladders therefore are fo difpo- 
fed, asnot to have refpett to feveral Centres, as ina Pear; but only the 
Stone, to which they all do moft exa@ly radiate; thereto conveying 
the feculent Sap, in {o many little Streams. This is beft feen, when the 
Fruit is full ripe. 
5. §- In this Fruit, while itis young, the gradual tranfmutation of 
the Inner Part of the Parenchyma into a Stone, is al{O more apparent. 
And {6 are the Three Coats, which ferve forthe Generation of the 
Seed; being now all very diftiné:; and remarkable, not only for 
their Bulk5 but alfo, the Analogy which they bear to the Three Mem- 
branesin many Viviparons Animals. Whereof I thall give a more par- 
ticular Defcription, when I come, in the following jPatt, to the Co- - 
vers of the Seed, 
6. §. A PEACH hatha much bigger stone, than either a Ply, 
or an Aprecock : and hath therefore, when full ripe, and efpecially in
