isit to be prefumed, that they bear a juft Proportion to thofe in the 
Trunk of the fame Tree ; and that therefore they are here larger, than 
in an Apple or Pear. The Skin likewife of a Plum, is more fibrous, 
thick, and tongh, than in thofe Fruits. The Ends of thefe Diverlitics 
we fhall prefently fpeak of. 
2. $. Of the Stone, among{t other particulars wherein the con- 
trivance of Nature is very admirable, I have formerly thewed, That 
it is compofed of Two or rather Three diftin& Bodies. One of them, 
the Lining ; which anfwers to the Coarin a Pear, And is originated 
from the Parenchyma, which the Seed- Branch brings along with ir, 
through the Chanel in the Side, and. at laft into the Hollow, of the 
Stone and is there fpread all over it: as when a {mall Glafs-Pipe, is 
blown and expanded into a Bubble. Or as ifa Bladder, being ftretch- 
out, and put through the Neck of a Bottle; were then blown up, fo 
as to be every where contiguous to the Sides, and become, as it were, 
the Lining of the Bottle. 
3. $. The Foundation or Ground of the Outer and more Bulky 
Part of the stone, is the Iner Part of the Parenchyma 3 and anfwers 
to the Acetar 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 42 
ges of the fame Fruit together. And in fome Stores; on the Surface 
whereof, (ome of the faid Tartareous Parts appear in diftind: Grains: 
So that whereas in a Pear, the Cakulary and the Acetary are diftin&, 
here in a Phi, they are thrown one into the other. Or, as fome 
Mineral Waters only make a Cruft about a Stick or other Bodies im- 
merfed 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 Craft 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 
(hall hereafter be fpoken of, when Lcome in the next Part, to the Co- 
vers of the Seed. 
4 $ AN APRECOCK is of the Plum-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 Fruit, asin a Pear; 
but all thrown off into the Stone: the Bladders therefore are fo difpo- 
fed, as not to have refpett to feveral Centres, asin a Pear; but only the 
Stone, to which they all do moft exaétly radiates thereto conveyin; 
the feculent Sap, in lo many little Streams. This is beft feen, when the 
Friit is fall ripe. 
25. §. In this Fruit, while itis young, the gradual tranfmutation of 
the Inner Part of the Parenchyma into a Stone, is alfo more apparent, 
And ‘fo are the Three Coats, which ferve forthe Generation of the 
Seeds being ‘now all very diftin& ; and remarkable, not only for 
their Bulk; but alío, the Analogy which they bear to the Three Mem- 
branes in many Viviparons Animals, Whereof | {hall give a more par- 
ticular Defeription, when I come, in the following Patt, to the Co- 
vers. oF the Seed,

or an Aprecock : and hath therefore, when full ripe, and ann
