Experiment XXXII. 
We have a farther proof of the great 
force with which vegetables imbibe moi- 
fture, in the following Experiment, *viz. I 
filled near full with Peafe and water, the 
iron Pot (Fig. 3 7.) and laid oh the Peafe a 
leaden cover, between which and the fides 
of the Pot, there was room for the air which 
came from the Peafe to pafs freely. I then 
laid 1 84 pounds weight on them, which (as 
the Peafe dilated by imbibing the water) 
they lifted up. The dilatation of the Peafe 
is always equal to the quantity of water 
they imbibe : For if a few Peafe be put in- 
to a Veffel, and that Veffel be filled full of 
water, tho* the Peafe dilate to near double 
their natural fize, yet the water will not 
flow over the Veffel, or at moft very incon- 
fiderably, on account of the expanfion of 
Jittle air bubbles, which are iffuing from the 
Peafe. 
Being defirous to try whether they would 
raife a much greater weight, by means of a 
lever with weights at the end of it, I com- 
preffed feyeral frefh parcels of Peafe in the 
fame Pot, with a force equal to 1600, 800, 
and 400 pounds $ in which Experiments, tlxf
