And yet, in all the fifty fix days which it flood thus, s 
very inconfide ^able quantity of Water bad gone off^ viz, 
fcarcely Twenty Grains ^ tho' the Sand continued moijl 
up to the top till the very laft. The Water had impart-

of the Tube. And, in the Viol, it had precipitated a 
greenip Sediment^ mixt with black%. To the bottom and

above. Other hke Tubes I fili'd with Cotton^ Lint^ 
Fith of Elder ^ and feveral other porous Vegetable Sub- 
fiances s fetting fome of them in clear Water : Others 
in Water tinged with Saffron^ Cochinele^ &c. And fe« 
veral other Trials were made, in order to give a Mecha^

"Juices in Plants : and of fome other Phenomena obferva-

the hotter Seafons^ in which the before recited Trials 
were made. 
Some ReJleBions upon the foregoing Experiments. 
I. In Plants of the fame kind^ the lefs they are in 
Bulk, the fmaller the ^antity of the Fluid Mafs in which 
they are fet is drawn off-, the Difpendium of it, where 
the Mafs is of equal thicknefs, being pretty nearly pro- 
portioned to the Bulk of the Plant. Thus that in the
