Philofopbical Hiftory of Plants. 
Plants; yet the Inward Ones, which, generally, are as Precife and 
Various as the Outward; we fee, how ufual it is, forthe beholding of 
Thefé, to be omitted by them. And befides, when we have obferved 
Nature's Work, as well as we can ; it may be no impediment to our 
beft Endeavours, to believe, That fome Parts of it, will ftill remain 
behind, Uxféex. So that if to be Seen, were the only End of it, it muft 
needs be wholly fruftrate, as to the greater number of Men; and, in 
fome part, as to all. Wherefore, we mutt fuppofe fome other Ends 
of the faid Varieties, which fhould have their Effeé, and fo Thefe, 
not bein vain, whether Men beheld them or not; which, are, there- 
fore, fach as have refpe& to Vegetation: That the Corn might grow, 
Jo3 andthe Flower, fo, whether or no Men had a mind, leifure, or abi- 
lity, to underftand how. 
18. g. Ifthen the Avatomy of Vegetables be fo ufeful a Mean, we 
ought not to ftreighten it; but to force this, as well as the reft, to its 
utmoft Extent. And therefore, firft of all, To go through all the 
Parts, with equal care 5 examining the Root, Trunk, Branch, Leafy 
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 Nu- 
ture, from the Seed forward, to the Seed : yet can it not but be ufe- 
ful, for That of Difleétion, 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 ‘fixe, foape, motion, age, 
Sap, quality, power, or any other way the fame, which may alfo agree, 
in fome one or more particulars, as to their Ivteriour Strudure : 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 1n both which, divers of them 
may be noted tochange, not only their Dimenfions, but their Natures 
alfo; asVeféls, do into Ligaments ; and Cartilages, into Bones, fome- 
times, in Awimals. And to do all this by feveral Ways\of Section, 
Oblique, Perpendicular, and Tranfverfe 5 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 Sefion, Together with the Kaife it will be neceflary to 
joynthe Microfcope ; and to examine all the Parts, and every Way, in 
the ufeof That. As alfo, that both Immediate, and Microfcopical 
InfpeGions, be Compared : fince it is certain, That fome things, may 
be demonftrated by Reafon and the Eye conjuné, without a Glafs, 
which cannot be difcovered by it; orelfethe difcovery is fo dark, as 
which, alone, maynot be fafely depended on. 
19. §. By thefe feveral Ways of Infpection, it will be requifite, To 
obferve their Compounding Parts as Simply confidered,and as varioully 
Proportioned, and Difpofed, -As Simply confidered, to note their Nuw- 
ber ; what, and whether the fame, in all: their Kizds, wherein dif 
ferent in the fame, or divers Vegetables: their Original, in part, or in ° 
whole: Strudure, as to their Contexture and their Cavities; . Their 
Coutexture, within themfelves feverally, and as joyned together : their 
Cavities, as to their size, Shape, and Number s in which a great va-
