the heat of the next day, fending up more Juyce, tbruft up 
higher from time to time, till it gets to the top , climbing thither 
as cwerd'by fteps : To which afcenc it is marvellouflyafljfted 
by the ftruftureof thefe Pipes, being divided into fquare par- 
ti tions, opening inio one another, and furnifh'd witb^fbmething 
that performs the part of Valves, endowed with a Spring. 
From thefe Pipes, he faith , do depend and break forth Ho- 
rizontal ranks of Baggs or bMUs , croffing thofe Fibres ; 
into which bubbles the afcending juyce, like a chyle, is dif- 
charged, and being ftay'd there a while, and mixed with the 
old juyce there refiding, comes to be fermented, and advan- 
ced to the nature of an Aliment: Whence it comes to pafs, 
that in many of thofe Bubbles there fall out due precipitacions 
of a tartareous matter , which is condenfed and hardned in 
thefe veiTels» And 'tis in thefe Bubbles , faich he further , that 
H)uch of this juyce is digefted, which afterwards is diftributed 
to the Woody, and oiher parts of the Plant. 
Bur, befides this preparation of the Aliment made in the 
B^y/^, there is another office, which that part feems to be ap- 
pointed for; and that is the increafe of the bulk of Plants, by 
adding yearly a coat or ring of Fibres, which being inter- 
woven by thefe Horizontal ranks of Bubbles , and by de- 
grees confolidated and hardned , do put on the nature of 
Wood. 
The Stem or trunck of Plants conGfts , 'according to him , of 
Liigneom fibres , tranfverfe ranks of Bubbles , and Mr-pipes, 
In young Trees ^ he faith, the ranks of thefe Bubbles pafs into 
the very Pith ; which pith is abounding in young Twigs , until 
by the growth and hardning of the ligneous fibres it waftes 
away. Now the clear Juyce , which through the Woody fila- 
ments rifeth up into the ftem and branches , is difcharged into 
the lateral appendages of the Bubbles, and there advanced, as 
hath been faid already, into a nourilliirig Juyce : And in Ani- 
mals the new Aliment enters under the form of Ghyle into the 
Veins, where being mingled with the old blood , which is en- 
dowed with feveral ferments , as the fympha^md others, and fo 
circulated into tl^e habit of the whole body , it enters into all 
the parts of it, in which it meets again with determinate fer- 
ments raifing them to the peculiar nature of every part , 
tranfpiring
