Tabite fide 
which, in that they differin nothing fave in their fize, I therefore on- 
ly here juft take notice of them. And thefé three Parts, /¢. the Adaiz 
Body, the Radicle, and the Plzme, are concurrent to the making up of 
a Seed 5 and no more than thefe 
15. §. Having thus taken a view of the Orgavical Parts of the 
Bean, and other Seeds; let us next examine the Similary, fe» thofe 
whereof the Organical are composd: a diftin& obfervation of which, 
for aclear underftanding ofthe Vegetation of the Seed, and of the whole 
Plant arifing thence is requifite: To obtain which, we muft proceed. 
in our Azatomy. ° 
16. §. Diffeting a Bea then, the firlt Part occurring is its Cuticle, 
The Eye and firft Thoughts, fuggeft it to be only a more denfe and 
gloffy Superficies; but better enquiry difcovers it a real Cuticle. ‘Tis 
fo exquifitely thin, and for the moft part, fo firmly continuous with 
the Body of the Beam, that it cannot, except in fome fmall Rag, be di- 
ftinGly feen , which, by carrying your Knife aflant into the Beaz, and 
then very gently bearing upward what you have cut, will {eparate,and 
fhew it felf tranfparent. This Cwticle isnot only fpread upon the Cox- 
vex of the Lobes, but alfo on their Flats, where they are contiguous, 
extending it felf likewife upon both the Radicle and Plume,and {o over 
the whole Bean. 
17. §. This Part, though it be fo far common with the Coats of 
the Beaz, asto be like thole, an Integument 5 yet are we ina quite dif- 
ferent Notion to conceive of it: For whereas the Coats, upon fetting 
the Beaz, do only adminifter the Sep, and, as being fuperfeded from 
their Office, then die ; as fhall be feen : this, on the contrary, with the 
Organical Parts of the Bean, is nourifhed, augmented, and by a real Vege- 
tation co-extended. : 
18..§. Nexttothe Cuticle, we cometothe Parenchyma it felf; 
the Part throughout which the Izner Body, whereof we (hall fpeak anon, 
is difleminated ; for which reafon I call it the Parenchywa. Not that 
we are fo meanly to conceiveof it, as if (according to the ftridter fenfe 
of that word, ) it werea meer concreted Juyce. For it is a Body 
very curioufly orgeniz'd, confifting of an infinite number of extreme 
{mall Bladders 5 as in Tab. 1. is apparent. The Surface hereof is fome- 
what denfe, but inwardly, ’tis ofa laxer Contexture. If you view it 
in a Microfcope, or witha very good Speéfacle-Glafs, it hath fome f- 
militude to the Pith, while fappy in the Roots and Trunks of Plants 5 
and that for good teafon, asinCh.2. fhall be feen. This is beft {een in 
green Beans. 
19: §. This Part would feem by its colour tobe peculiar to the 
Lobes of the Bean; butas is the Cuticle, fois this alfo, common both to 
the Radicle and Plume; that is, the Parexchywa or Pulp of the Bean, as 
to its effential fubftance, is the fame in all three. The reafon why the 
colour of the Plume, and efpecially of the Radicle, which are white, 
is fo different from that of the Lobes, which are green, may chiefly de- 
pend upon their being more compaét and denfe, and thence their dif- 
ferent Tin@ures. And therefore the Lobes themfelves, which aregreen 
while the Beaw is young; yet when it is o/d and dry, become whitifh 
too. And in mazy other Seeds, as Acorns, Aluouds, the Kernels of Ap- 
ples, Plums, Nuts, Gc. the Lobes, even fiefh and young, are pure white as 
the Radicle it (elf.
