where there is a Stone or Shell over it, asin the Barbado Nut, it is 
fofts but where there is none, as in Nux Vomica, Afh, &c. ‘tis hard 5 
‘and fo it fèlf inftead of a Stone. Asalfo, That it becomes hard, only 
by the proper Nature of its Parenchyma, and the exquifite fizallnefs of 
the Bladders of which it confifts. Whereas a Stone; is alfo hardened by 
the Lees or Tartar of the Sap which finks into it,and thereby petrifies it 
(2) as hath been faid. So that whereas a Stone, as it lies in the Ground, (a) P.3. 
only cleavs in certain Places, but continues hard : This Cover, like fome Ch, 3. 
Horns, upon the due acceflion of Moiftire, doth gradually become 
Soft. “Whereby, as while it is hard, it performs the Office of a Stone, 
in guarding the Seed til the proper Seajor for its Growth: So after- a 
wards when it is foft, it anfwers, as in Orach or Dock, (b) to api- (b) Ch, 3.

Of the FOETUS or true SEED: and firft of the 
RADICLE and LOBES. 
A V ING difcourfed of the Covers, I come next to 
B the Seed or Fetus it {elf Of the Shape and Po- 
lá, fiure whereof, I thall give fome Examples, firit, a- 
mong thofe with the thinner fort of Covers; and 
then, of thofe with the Bulky one: where I fhall 
fpeak only of the Lobes, or: Main Body, and the 
7 WOO Radicle. Next, I fhall deferibeithe feveral forts óf 
Nodes or Buds of Seeds. And laftly, the feveral Parts, of which the 
Lobes, Radicle, and Buds are compounded. 
2: $. Among Seeds with the Thinner Covers, are thofe of all forts of 
Corn and Grafs, Of a different make, from that of moft other Seeds + 
The Main Body being not divided into Lobes, but one entire Piece, 
doubled in the form of a Pair of Lipps. And» whereas commonly, 
the whole Seed is very Softand Oyly here, only thofe two minute 5 
Parts, which become the Root and Stalk, are fo: The Main Body 
being of a different Subftance ; when the Cormis ripe, hard and friable 5 
but when it is fown, eafily colliquable into a kind of Milk or Chyle, fo 
that, in fome refpeéts, it hath a near Analogy toaVitellum. For as that 
is gradually melted into'a fart of Chyle,: and by the Branches of the Du- 
Gus Inteftinalis carryed into the Bowels of the Chick: So is this, intoa 
like subitance, and by. the Branches of the Seminal Root ( formerly 
defcrib'd ) conveyed tò thofe Parts, which become: the future Plant. B.1, Ch.i 
3- 6. Of Relation .to this Kind, the Seeds of Dates, and of fome 
other like Plants, may. be efteem’d. For that which is commonly cal- 
led the Stone, feems indeed to be the Mair Body of the seed, doubled 
or folded up in the fame manner as inCorz. To which that Part which 
becomes the Plant, is annexed, But whereas in Cor», ’tis placed at Tab. 75.
