19. §. Another ufe is for Augmentation ; or, the capacity for 
the due {preading and ampliation of a Tree or other Plant , are its, 
Leaves. For hetein'the Ligvous Body being divided into {mall Fibres, 
and thefe running all along their lax and {pongie Parenchyma; they 
aré thus a Body fit'for the imbibition of Sap, and eafie Growth. Now 
the sap having a frée reception into the Leaves, it {till gives way to 
the ext fucceeding in the Branches and Truwk, and the voyding 
of the Sap in thefe, forthe mounting of that in the Root, and ingrefs 
of that in the Growad, But were there no Leaves to make a free 
reception of Sap, it muft be needs be ftagnant in all the Parts to the 
Root, and fo the Root being cloge’d, its fermenting and other Offices 
will be voyded, and fo the due Growth of the whole. As in the mo- 
tion of a Watch, although the original term thereof be the Spring, yet 
the capacity for its continuance in a due meafure throughout all the 
Wheels, is the free and eafie motion of the Ballance, 
20. §. Laftly, As the Leaves fubferve the more copious advance- 
ment, fo thehigher purity of the Sap. For this being well fermen- 
ted both in the Root, and in its Afcent through the Trwwk, and 
fo its Parts ptepar'd to a farther {eparation ; the grofler ones are 
{till depofited into the Leaves ; the more elaborate and effential only 
thus fupplied to the Flower, Fruit and Seed, as their convenient Alj- 
ment. Whence it is, that where the Flowers are many and large, in- 
to which the more odorous Particles are copioufly receiv'd, the green 
Leaves have little or no fmell sas thofe of Rofé-tree, Carnations, French- 
Marigold, Wood-bind, Tulips, &c. But on the contrary; where the 
Plomers are none, or fmall, the green Leaves themfelve are likewife of 
a ftrong favour as thofe of Wormwood, Tanfie, Baum, Mint; Rue; 
Geraninm Mofchatum, Angelica, and others. 

oAn Appendix. 
Of Thorns, Hairs and Globulets; 
Hovis ave of two kinds, Lignous and Cortical. Of the firt are 
fuch as thofe of the Hawthorn, and are conftituted of all the 
fame fubftantial Parts whereof the Germen or Bud it felf, andin a 
like proportion: which alfo in their Infancy are fet with the refem- 
blances of divers minute Leaves. Ofaffinity with thefe are the Spinets 
or Thorny Prickles upon the Edges and Tops of divers Leaves, as of 
Barbery, Holly, Thiftle, Furze, and others 5 all which I think ate the 
filamentous extremities of the Lignous Body theathed in the Shiv, But 
this principal differnce betwixt a Bud and thefe Lignous Thorns, isob- 
fervable; That the Bud hath its Original from the Inner part of the 
Lignous Body, next the Pith: But thefe Thorzs, from the outer, and 
lefs fecund Part ; and fo produceth no Leaves, but is, as it were, the 
Mola of a Bud;
