fome thicknefs, as in Plevs, Borage, Scabious. Yet always extream 
thin at the Tzp of the Radicle ; the more eafily to break and yield to 
it, as the Secundine to the Fetus, when it firft fhoots into the Ground. 
And fometimes, as in the Seeds of'an Orange, it hath at cne end, the 
refemblance of a Placenta. But of this, and the two upper Coats, I 
thall give a further Defcription in the laft Chapter. 
9. §. AS ALL Seeds are ex Ovos fo there are many with thin 
Covers, as of Orach, Spinage, Beet, and the reft of that Tribe, 8c. 
which befides the Albumen or clear Liquor out of which they are bred; 
have alfo, a Vitelum, or a Body thereunto Azalogus : being neither part 
of the Seed, nor part of the Covers, but diftin& from them both. .With 
‘refpect to the Bulk of the Seed, very large, as white as Starch, and pret- 
ty friable, like good Rice or Barley: of a roundith Figure, and grooved 
on the Girth, fo asto have a double Edge ; Whereby the Seed, which 
is long and flender, lies round it, as a Sack of Corn upon a Pack-Saddle 
ora Rope upon a Pully-wheel. Upon my firft notice hereof, it feemed 
to anfwer to a Placenta. But upon further confideration, the Analogy 
doth not hold betwixtahem. For the Placenta lies without the atem- 
branes in which the Fetus is conteined: whereas this body lies within 
the Covers contiguous to the Seed, and fo becomes its firlt and fineft.A- 
liment, as the Yelk doth tothe Chick, For which purpofe, as in the Ge- 
neration of the Seed, it isa pure Milky Chyle 5 So in its Vegetation, it is 
converted into the like again. 
_ Io. §. The fame Body for Suftance, is obfervable in the Seeds of 
Rhapontich, Dock, Sorrel, and the reft of that kindred, with this difz 
ference; That whereas in Orach, &c. the Seed only lies upon it 5 here, 
the main Body or Lobes of the Seed are immerfed therein, the Radicle 
ftanding naked or above it. So that the {aid Lobes, and therein the 
Serminal-Rovt are beded herein, as in aTub of Meal or alittle pot of pure 
refit’d Afould, neceffary for the firft Vegetation of the Radicle, 
11. §. BY THESE midle Steps, Nature proceeds from the 
Thiner Covers of Seeds 5 or thofe, which after the Generation of the 
Seed is finifhed, thrink up; to the Bulky Kind, or thofe which keep 
their Bulk after they are dry. Wherein, not only the Lobes, as in 
Dock, but the whole Seed is immediately lodged. Different in Sub- 
fiance, Shapeand Bulks but always many times biger than the true Seed 
withinit: for which it is commonly miftaken 5 but isno more the Seed, 
than is the Stone of a Plum, the Kerzel, 
12, §. Inthe Barbado Nut, ‘tis White, Soft, Conick-oval, and tas 
king all its Dizentions, 8 or 10 times bigger than the Seed within it. 
In Afhen Keys, ‘tis of a fad Colour, hard, yet fomewhat Oyly, Oval and 
iat, and of the fame Bignefs asin the Barbado Nut, with refpeé to the 
Seed. In the Fruit commonly called Nux Vomica Officivarnes, ’tis of 
the,Colour and Hardnef; of a Cows-Horne and makes almoft the whole 
Body of the Fruit, being about 14. 0r 15 times the Bulk of the Seed, 
In Goofgrafs or Cliver *tis of the like Horny subftance, but fhaped fome- 
what like a Bowet with the Riv tuckt in. And fo ina Coffee-Berry; but 
rowled or foulded up intoa kind of Oval Figure, with a Notch or Ri- 
ma through the Length, where the two Ends mect. With other diver: 
fities which will beft be underftood, when I come prefently to the De: 
Jeviption of the Seed herein contained,
