43. §. The Impediments of our apprehenfion ‘hereof are the Co- 
lour, Size and Shape of the Diffinilar Leaves. Notwithftanding, that 
they are nothing elfe but the Main Body of the Seed, how 1 came 
firft to conceive, and afterwards to know it, was thus. Firft, 1 ob- 
ferved in general, that the Dilfimilar Leaves, were never jagg’d, but 
even edg’'d: And feeing the even verges of the Lobes of the Seed here- 
to refpondent, I was apt to think, that thofe which were fo like,might 
prove the fame. Next defcending to particular Seeds, [ obferved,firft, 
of the Lupine 5 that, as to its Colour, advancing above the Ground, 
(as it ufeth to do) it wasalways Changed into a perfet Green. And 
why mightnot thefame by parity of Reafon-be inferred ofother Seeds 2 
That, as to its fize,it grew but little bigger than when firftfet. Whence, 
asI difcern’d (the Augmentation being but little) we here had only 
thetwo Lobes: So, (as fome augmentatiot there was) I inferrd the 
like might be, and that, in farther degrees, in other Seeds. 
44. §. Next of the Cacumber-seed, That, as toits Colour, often 
appearing above ground,in its primitive white, from white it turns to 
yellow,and from yellow to greens the proper colour ofa Leaf: That, 
as to its fize, though at its firft arife, the Lobes were little bigger than 
upon fetting 5 yet afterwards, as they chang’d their Colour, fo their di- 
menfions alfo, growing to a three-four-five-fold amplitude above their 
primitive fize, But whereas the Lobes of the Seed, are in proportion, 
narrow, fhort and thick : how then come the Diffimilar Leaves, to be 
fo exceeding broad, or long, and thin? ~The Queftion anfwers it felf: 
For the Diffimilar Leaves, for that very reafon are fo thin, becaufe fo 
very broad orlong; as we {ee many things, how much they are ex- 
tended in length or breadth, fo much they lofe in depth, or grow 
more thin; which is-that which here befalls the now effoliated Lobes. 
For being once difimprifcned from their Coats,and the courfe ofthe Sap 
into them, now more and more encreafed; they muft needs very confi- 
derably amplifiethemfelves : and from the manner wherein the Semi- 
nal Root is branched in them, that amplification cannot be in thick- 
nef, but in length or breadth. In both which; in fome Diffimilar 
Leaves, ’tis very rematkable 5 efpecially in length; as in thofe of Let- 
tice, Thorn- Apple, and others; whofe Seeds, although very fmall, yet 
the Lobes of thofe seeds growing up into Diffimilar Leaves,are extended 
anInch, and fometimes more, in length. Though he that fhallattempt to 
geta clear fight of the Lobesof Thorn-Apple,and fome others,by Diffecti- 
on,will find it no eafie Task 5 yet isthat which may be obtained 5 and in 
the Laft Book fhall be fhew’d. From all which, and the ob- 
{ervation of other seeds, I at laft found, that the Diffimilar Leaves of 
a young Plant, are nothing elfe but the Lobes or Main Body of its 
Seed. $o that, as the Lobes did at firft feed and impregnate the Ra- 
dicle into a perfed Root 5 fo the Root, being perfected, doth again feed; 
and by degrees amplifie each Lobe into a perfect Leaf.

45. §. The Original of the Diffimilar Leaves thus known, we un- 
derftand; why fome Plants have nones becaufe the Seed either rifeth 
not, as Garden-Beans, Corn, &c. Or upon rifing, the Lobes are little 
alter'd, as Lupines, Peafé, &c. Why, though the proper Leaves are 
often indented round; the Diffimilar like the Lobes are even-edg’d. 
Why, though the proper Leaves are often hairy; yet thefe are ever 
fmooth. Why fone have more Diffiailar Leaves than two, as crf’,
