Of the Fruit . 
Of a plumb, and fome other fruits of the 
fame kind. 
Plumb confifts of a parenchyma, the two general 
iT kind of veffels, and a ftonej and in proportion to 
the bulk of the fruit, hath more veffels than an apple or 
pear. Alfo in plumbs, all thefe veffels are braced together 
into one uniform piece of net-work, every where ter¬ 
minating at an equal diftance from the circumference, the 
ikin is fibrous and tough. 
The ftone is compofed of two, or rather three diftindt 
parts, one of them the lining, taking its rife from the 
parenchyma, which the feed branch brings along with it, 
through the channel in the fide, and at laft into the hol¬ 
low of the ftone, and is there fpread all over it. 
The foundation or ground of the outer and more bulky 
part of the ftone, is the inner part of the parenchyma, 
upon which the tartareous parts of the fap are continually 
precipitated, and thereby petrified, as appears on com¬ 
paring the feveral ages of the fame fruit together ; on the 
furface of many ftones, fome of the faid tartareous parts 
appear in diftindt grains. 
An apricock is of the plumb kind, hut fome things are 
herein better obferved, as firft the pofition of the bladders 
of the parenchyma; for the tartareous parts of the fap, 
not being here difperfed in little grains, throughout the 
fruit as in a pear, but are all thrown off into the ftone 3 
therefore the bladders all radiate exactly to the center of 
the ftone, conveying thereto the feculent fap, in fo many 
little ftreams. This is beft feen when the fruit is full 
Ape. 
The gradual tranfmutation of the inner part of the 
parenchyma into a ftone, is alfo more apparent in this 
fruit.
