latcd by imbibing the water) they lifted 
up. The dilatation of the Pcafc is always 
equal to the quantity of water they imbibe : 
For if a few Peafe be put into a VelTel, and 
that Veflel be filled full of water, tho’ the 
Peafe dilate to near double their natural 
fize i yet the water will not flow over the 
Veflel, or at moft very incgnfiderably, on 
account of the expanfion of little air bub- 
bles, which are ifliiing from the Peafe. Be- 
ing 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- 
prefled feveral frefh parcels of Peafe in the 
fame Pot, with a force equal to 1600, 800, 
and 400 pounds 5 in which Experiments, tho* 
the Peafe dilated, yet they did not raife the 
lever, becaufe what they increafed in bulk 
was, by the great incumbent weight, prefled 
into the interftices of the Peafe, v/hich they 
adequately filled up, being thereby formed 
into pretty regular Dodecahedrons. 
We fee in this Experiment the vaft force 
with which fwelling Peafe expand, and 'tis 
doubtlefs a confiderable part of the fame 
force which is exerted, not only in pufli- 
ing the Plume upwards into the air, but
