Philofopbical History of Plants. 
Plants; yet the Inward Ones, which, generally, are as Precile and 
Various as the Outward 5 we fee, how ufual it is, forthe beholding of 
Thefe, to be omitted by them. And befides, when we have obferved 
Nature's Work, as well as we can 5 it may be no impediment to our 
belt Endeavours, to believe, That fome Parts of it, will (till remain 
behind, Unfeer. So that ifto be Seen, were the only End of it, itmuft 
needs be wholly fruftrate, as to the greater number of Men; and, in 
fome part, as to all. Wherefore, we muft fuppofe fome other Ends 
of the faid Varieties, which fhould have their Efe&#, and fo Theft, 
not bein vain, whether Men beheld them or not; which, are, there- 
fore, fuch as have refpect to Vegetation: That the Corn might grow, 
fo; andthe Flower, fo, whether or no Men had a mind,leifure, or abi- 
lity, to underftand how,

ought not to ftreighten it; but to force this, as well as the reft, to its 
utmoft Extent. And therefore, firft ofall, To go through all the 
Parts, with equal care; examining the Root, Trunk, Branch, Leaf, 
Flower, Fruit, and Seed. Then to Repeat or Retrograde the Dif- 
fection, from Part to Part : in that, although the beft Method of De- 
livery, for clear Difcourfe, can be but one, according to that of Na- 
ture, from the Seed forward, to the Seed : yet can it not but be ufe- 
ful, for That of Diffection, to proceed to and fro; fomewhat or other 
being more Vifible in each feveral Part , from whence ftill an Hint 
may be taken, for the ufhering in the obfervation of it in the others. 
To examine, again, not only all the Parts,but Kinds of Vegetables, and 
comparatively, to obferve divers of the fame fize, fhape, motion, age, 
Sap, quality, power, or any other way the fame, which may alfo agree, 
in fome one or more particulars, as to their Interiour Strudture : and to 
make this comparifon, throughout all their Parts and Properties. To 
obferve them likewife, in feveral Seafons of the Year, and in feveral 
Ages of the Plants, and of their Parts 3 in both which, divers of them 
may be noted to change, not only their Dimenfions, but their Natures 
alfo; asVeffels, do into Ligaments, and Cartilages, into Bones, fome- 
times, in Animals. And to do all this by feveral Ways of Section, 
Oblique, Perpendicular, and Tranfverfe ; all three being requifite, if 
not to Obferve, yet the better to Comprehend, fome Things. And 
it_will be convenient fometimes to Break, Tear, or otherwife Divide, 
without a Seéfion. 
Together with the Köfe it will be neceflary to 
joynthe Microfeope ; and to examine all the Parts, and every Way, in 
the ufeof That. As alfo, that both Immediate, and Microftopical 
Infpeétions, be Compared : fince it is certain, That fome things, may 
be demonftrated by Reafon and the Eye conjunét, without a Glaf, 
which cannot be difcovered by it ; or elfe the difcovery is fo dark, as 
which, alone, may not be fafely depended on.

obferve their Com; sounding Parts; as Simply confidered,and asvarioufly 
Proportioned, and Dipped. As simply confidered, to note their Num- 
ber 5 what, and whether the fame, in all: their Kinds, wherein die

Whole: Strudue, as to their Contexture and their Czvitiess Their
