11. $. In Beet, they ftand in feveral Rings; and every Rir . 
made of Rays. In Cumfry, the Rays and Rings are feparate; thoje 
Tab, 8,9. ftand without, thefe next the Centre. In Dandelion, they ftand alto- 
gether, and make a little Rope, in the Center it felf In Geranium, 
and others of that Kindred, they make a little Thred, in the fame 
place. And in Skirrer, they ftand in two Threds, near the Centre.

Root, into Three little Wedges, with their poynts meeting exactly 
in the Centre. In Cinguefoyle, and Strawberry, they are alfo polturd 
in three Conjugations, triangularly. In the young Roots of Oak , 
they ftand neither in Radiated, nor otherwife ftrait, but Winding 
Lines. And in Borage the pofition, of many of them, is Spiral. As 
likewife, fometimes, in Mercury, or Lapathum unttuofum. In Horfe- 
Radith, they ftand more confuled neither in Rings nor in Rays; yet 
their feveral Conjugations, are radiated: with very many other dif- 
ferences, 
13. $. The Quantity of thefe Vefels, as to the fpace they take up 
in the Root, is to be computed Two ways, By their Number, and 
Size. Their Number may, in fome Roots, and in fome meafüre, be 
judged of, by the bare Eye; having, frequently, a whiter furface 
than the other Parts. As alfo their Size; the Bore of thefe Veffels be- 
ing greater than that of the Lignows in all Roots; efpecially in- fome. 
For if you take the Roots of Vine, Fenil, Dandelion, Plum-tree, El. 
der, Willow, &c. and lay them by, for fome time, to dry 3 and then, 
having cut off a very thin Slice of each, tranfverfely 3 if you hold up 
thofe Slices before your Eye, fo as the Light may be trajected through 
the faid Vefels, they hereby become vifible, as notably different, both 
in Number and Size. 
14. $. Butundeceitful and accurate Obfervation of both their 
Number, and Size, muft be made by the Microféope 5 and fo they will 
appear to be much more various. In Biffort, Skirret, they are very 
few; in Beet, very many: betwixt which extreams there are all De- 
grees; asin Orpine, Venns Looking-Glafs, Scorzonera, Great Celandine, 
Peony, Borage, Fenil, &c. may befeen. So their Size, in fome is ex- 
tream finall, asin Strawberry, Biftort, Valerian 5 in others very great, 
asin Afparagus, Buglofs, Vine. They are alfo of feveral Sizes in one 
and the fame Numerical Root; but in fome, are lef varied, asin Li- 
Tabs 10, to lite mon bulbofm, Afparagus, Bughf’s in others, more, as in Bryony, 
ab. 10, to 
Lovage. Amongft all Roots, they vary by about Twenty Degrees 3 
as by comparing the Roots of Vine, Thorn-Apple, Bryony, Lovage, 
Fenil, Wild Carrot, Saxifrage, Parfley, Peony, Hore-hound, Cinguefoyh, 
Strawberry, Exc. together, may be feen. Some of thofe in the Vine, 
being of the greatelt Size; appearing through a good Glafs, at leaft 
one Third of an Inch in Diametre: thofe in Strawberry, and that 
Kind, of the fmalleft; moft of them appearing, in the fame GI, 
no bigger, than to admit the poynt of a fmall Pin, according to 
the Standard, in Tab. 12. Sec alfo the Figures of fo many of them 
as are drawn.
