Of Vegetation . 345 
That the force of dilating fap and air, in- 
cluded in the innumerable little vcficles of 
young tender (hoots and leaves, is abundantly 
fufiicient for the extending of (hoots, and ex^ 
panding of leaves, we have evident proof 
from the great force we find in the fap of 
the Vine, chap. 3d. and from the vaft force, 
with which infinuating moifture expanded 
the Peafe. Experiment 32. we fee the great 
power of expanding water, when heated in 
the engine to raife water by fire : And wa- 
ter with air and other adlive particles in ca- 
pillary tubes, and innumerable fmall veficles, 
do doubtlefs adt with a great force, tho* ex- 
panded with no more heat than what the 
Sun’s warmth gives them. 
And thus we fee that nature exerts a con- 
fiderable, tho’ fecret and filent power, in car- 
rying on all her produdlions; which demon- 
ftrates the wifdom of the Author of nature 
in giving fuch due proportion and dirediiou 
to thefe powers, that they uniformly con- 
cur to the produdlion and perfedtion of na^ 
tural Beings 3 whereas were fuch powers 
under no guidance, they muft: neceffarily 
produce a Chaos ^ inftead of that regular and 
beautiful fyftem of nature which we fee.
