To clear the better allhehathdifcourfed of the ftrudureof a 
Plant, herefembles the whole Bt?/^/;' of it to a piece of fine Bo fie- 
Uce^ at fucb time as 'tis wrought upon the Cufliion. ¥or Jaith he^ 
all the Varemhymom parts, as the Pith, Infertions, and Parenchyma 
of the Bark, are nothing elfe but Lace-rvork ; the Ffters of the 
Pith running horizontally, as do the threds in the Lace,and bound- 
ing the feveral Bladders of the Pith and Bark, as the threds do the 
feveral holes of the Lace ; and making up the Injertiom without 
Eladders,or with very fmall ones , as the fame threds like wife do 
theclofe parts of the Lace; which they call the cloath-mrkthnd laft- 
ly, the Vejfels^ ftanding perpendicular ly^xm crofs to the horizontal 
fibers 5 even as in the Lace the Pins do the threds. And this he 
makes to be the true texture of a Plant, and the general compofure, 
HOC only of ^ Branch, but of all the other parts, from the feed to 
the feed. 
To proceed to the fecond part of this Book, which gives an Ac-

natomy, andfliewingthc/Z/^thatmaybemadeof the fame in or- 
der to explicate the manner of Vegetation \ the chief Heads, to 
which this whole matter is reduced, are thefe feven ; viz^ 
u The Motion and Courfe of the SAP \ where he obferves rn^(> 
kinds of Bleeding in the Plants ; gives the caufes of both 5 toge- 
ther with the caufe of the Sap's Afcenf. 
2* The motion of theklK'-^ that it firft enters the Plant by the 
Trunk, but chiefly by the Root, and is thence in a peculiar man- 
ner diftributed throughout the whole Plant.- Where he notes the 
ufe of the hferticns herein, and compares this ufe with that of the 
Membranous parts of the Lungs. 
3. The Struciure of the PARTS ; where he explains the Uni- 
on of the Eark 10 the Body of the free, with the caufe of it : Con- 
fiders the various Surface and Falling off of the Bark; the leffen- 
ingof the Tith in the Elder branches; the ruptures of the Pirb, 
and for what ends made ; further, how tlie jlir-vcjfels come to be 
lefs in the Trunk of the fame Plant than in the Root ; and thofe of 
the firft year ufually tnucb lefs than thofe of the years following 5
